Radial 500 Series

The Powerhouse is a 10 module 500 series power-rack designed to accommodate both older and newer 500 series modules and provide the studio with maximum density in a standard 19" rack frame.

The design begins with heavy 14 gauge steel construction and durable powder coat finish for maximum shielding against noise and greater durability when subjected to road use. An 'easy glide' slider tray makes it painless to align the PCB connector to the 15 pin card edge receptacle when swapping modules. Once connected, the rear panel sports a standard array of XLRs to connect to and from the workstation or mixer. This is augmented with a series of ¼" TRS connectors that enable cross-patching and open the door to the excitement of parallel signal processing. Instead of having to hard patch modules together using a cable, the Powerhouse incorporates an innovative feed switch that instantly connects the signal to the adjacent module. This makes building signal chains quick and eliminates the need for extra cables. And unlike older racks that require soldering when modules are used in stereo, the Powerhouse is equipped with a stereo link function that takes care of the task with a simple slide of a switch.

Unlike older racks that are limited to an average of 130 milliamps per slot, the Powerhouse boasts a 1600 milliamp power supply that lets you share the power as needed. This means it can deliver 300 milliamps to your two tube preamps and still have over 1000 milliamps left in the pool! And just like all Workhorse racks, the Powerhouse is equipped with extra safety features to ensure safe use when mixing and matching various brands.

The Powerhouse delivers more flexibility than all others.

The Workhorse WR-8 is a trimmed down version of the Tec Award winning Workhorse power rack without the 8 channel summing mixer. This enables those that may not need a mixer to join in the fun while leaving the door open to upgrade in the future.

Like the Workhorse, the WR8 features eight slots to accommodate both Radial modules and other API Lunchbox™ compatible modules. An innovative slide-in tray makes loading modules easy! Rear connections include XLR and ¼" TRS inputs and outputs plus parallel connections via D-Subs. Unlike older API type racks that need to be hard patched, the WR8 features an innovative FEED switch that lets you connect modules in series by simply setting the switch to suit. This leaves the other connectors open for mult'ing, parallel processing and cross patching.

Stereo-ready modules such as compressor-limiters no longer need to have inside traces soldered! A simple LINK switch performs the connection and lets you revert back to normal without de-soldering. Radial also upgraded the 500 series spec with Omniport, a ¼" TRS connector that enables the manufacturer to assign a special module-specific function to increase functionality. Radial modules employ the Omniport in a variety of ways. For instance, the PowerPre assigns the Omniport as an instrument input, the Komit is a key input for the side chain and the JDV-Pre uses it as a direct box output for stage use.

The WR8 provides extra power to the modules for more headroom with over 1600 milliamps of shared power for the 8 slots. This enables you to use power hungry devices like tube preamps with confidence. The external supply makes international travel easy with 100V to 240V compatibility and the use of a standard IEC connector. To keep modules safe, the WR8 is equipped with protective circuitry to prevent mishap should improper connections be made.

The WR8 power rack - All the power of a Workhorse without the mixer.

The Radial Workhorse is a modular rack and mixer that combines the popular 500 series platform with an incredibly flexible patching system to let you create the ultimate studio environment.

Equipped to handle up to eight modules, the Workhorse lets you mix and match preamps, EQs and compressors and bring them all together in one rack. Individual modules may be accessed on the rear panel following the traditional API™ format or bussed to the built-in 8x2 summing mixer for left-right signal panning, level control and muting. Once mounted, a unique 'feed' functon lets you configure modules to feed one another in series to create the channel strip of your dreams!

The master section features a traditional virtual ground mix buss combined with the superb sonic performance of Jensen Transformers on the main mix outs. A separate stereo monitor output provides playback, plus a super-loud dual-output headphone amp lets the engineer share the mix with the artist. Multiple Workhorses may be ganged together using the expansion buss to build 16, 24 or even 32 channel systems.

Rear panel connectivity is extensive: Each channel is equipped with traditional XLR input and output. This is augmented with ¼" TRS jacks for balanced or unbalanced connectivity. A special Omniport™ jack delivers module-specific functionality that can range from an extra output, ducking input or effects insert depending on the module design. The Workhorse comes ProTools™-ready with 8-channel D-subs for the inputs and outputs plus third D-Sub gives you access to the built-in summing mixer for those that prefer the added warmth of analogue summing. Powering concerns are addressed with a unique 'pooled' supply that shares 1200 milliamps of current between the available 8 slots. This allows high current demand modules to exceed the usual limitations of other 500 series racks without the worry of brown outs.

Plug and play easy to use, the Workhorse brings the fun, excitement and creative advantage of warm-sounding analogue to the modern \ digital studio.

The SixPack is a desk-top power rack for 500 series modules that lets you mix and match up to six modules and safely power them to create a stereo channel strip or unique signal chain.

The design begins with a heavy 14 gauge steel construction and durable powder coat finish. This provides extra durability when moving the SixPack around the studio while also providing better shielding against stray magnetic fields. To reduce induced noise, the power supply is external and connects using a 5-pin locking XLR. To ensure positive contact, the module card-edge connector is mated to a double sided EDAC 15-pin receptacle that is 100% compatible with the old API pin format. Extra safety is built-in to ensure malfunctioning modules will not harm the SixPack or other modules that may already be connected. And with 1600 milliamps of shared current, the SixPack exceeds all others with an average of over 265 milliamps per slot to ensure even the most power hungry tube modules will be satisfied.

Rear panel connectivity includes individual XLR input and output connectors wired in parallel to ¼" TRS connectors. These may be used as mults or for cross-patching various modules together to create innovative sounding signal paths. A set of 25-pin D-Sub connectors enable the SixPack to easily integrate with a Workstation. Two XLR connectors are front mounted and may be routed to the D-Sub or to inputs 1 and 4 to make patching in a microphone more expedient. Extra features include a feed switch that patches one module into the next, a link switch to combine stereo-ready modules and Omniport, a ¼" TRS jack that adds extra functionality.

The convenient design lets you set the SixPack down on your work surface or carry it around the studio using the side-mounted handle. Optional flanges let you mount it in a 19" rack if you plan to take your SixPack on the road!

The Radial SixPack – the tastiest 500 series lunch basket ever!

The Cube™ is a three module desktop power rack designed to bring the fun and excitement of 500 series modular audio to everyone!

Unlike other 500 series enclosures that are usually rack mounted, The Cube™ is designed to sit on the desktop or be carried around the studio using the convenient top-mounted handle. This enables the engineer to position instrument and microphone preamps as close to the source as possible for improved signal to noise. The Cube can also be recessed into the work surface using the optional mounting flanges. These allow either flush mounting or 30° angle mounting to optimize viewing position.

Following the criteria established by the Radial Workhorse, the PowerStrip is 100% backwards compatible with older API modules while being optimized for Radial's expanding range of preamps, processors and routing devices. Construction begins with a 14 gauge steel frame and features dual gold contact EDAC 15-pin connectors for optimal signal transfer. To maximize headroom, the external supply delivers 500mA of current for power hungry modules plus a separate 48V phantom tap delivers a full 10mA of current for microphone preamps. Rear panel connectivity includes standard XLRs for each slot along with ¼" TRS connectors for multiple modules, cross patching and parallel processing. Instead of the traditional 'hardwire patch' system employed by others, The Cube employs an innovative feed function that patches modules together in series without the need of a cable. And stereo modules no longer need to be soldered to be paired, they can now be sync'd together using a simple switch. The Cube is also equipped with Omniport on each slot. This TRS jack enables the module manufacturer to implement a unique function for a given module such as a key input on a gate.

The Cube... The World's most advanced desktop power supply for 500 series modules.

The Radial PowerPre™ is a high performance microphone preamplifier designed to be used with the Radial Workhorse and other 500 series modular racks. It features 100% discrete components for optimal signal transfer and employs a 'vintage' Hammond broadcast output transformer for warmth and exceptionally smooth tone.

The design begins with a front mounted XLR for instant connectivity plus a recessed 48V phantom power switch for safety. Unlike most mic preamps that require careful gain adjustment to avoid troublesome noise, the PowerPre is equipped with the newly developed AccuState™ input stage that automatically optimizes signal-to-noise at all levels with up to 55dB of gain. This is supported with a full 10 segment LED meter for precise signal monitoring.

To add extra character; a 3-position Vox control lets you set the PowerPre to 'breath' for added high frequency air such as when accentuating a vocal track or adding harmonic content to an acoustic guitar. The 'punch' setting adds body when recording electric guitar or can be used to fatten a voice. When set to linear, the PowerPre delivers a truly natural rendering for orchestral recording that will suit the most demanding purist. This is augmented with a gentle high-pass filter that helps control low end resonance when layering acoustic instruments.

Ultra quiet, low noise and exceptionally warm sounding… the PowerPre makes spectacular audio easy.

The Radial JDV-Pre is a unique preamplifier designed specifically to capture the natural tone and distinct character of the instrument. This may sound like another 'marketing line', but unlike mic preamplifiers that are centered on 'the microphone', the JDV-Pre is completely focussed on the various types of pickups used while transferring the signal without introducing distortion or artefact of any type.

The design begins with a 100% discreet class-A amplifier for optimal signal transfer. But unlike all other amplifier designs, the JDV-Pre's front end is completely void of the negative feedback loops normally used to stabilize the circuit. This revolutionary design eliminates the use of phase-cancellation which inevitably degrades the signal. This is augmented with Drag Control™ load correction that allows the engineer to optimize the load on the instrument pickup for the most natural rendering.

The quest for perfection does not stop there. When the impedance is set for piezo pickups, the JDV-Pre remains unbelievably quiet. Accustate gain control not only allows complete freedom over the signal path, but retains the signal-to-noise ratio at all levels. Acoustic instruments are further advantaged with a fully variable high-pass filter that gently rolls of the low end to eliminate troublesome body resonance while allowing each instrument to sit more comfortably in the mix. To address instrument microphones, the JDV-Pre features a transformer coupled balanced mic input with available 48V phantom power for condenser microphones. Connection is made via standard 500 series rack XLR input.

Natural sounding, transparent and remarkably quiet, the JDV-Pre is without a doubt, the finest instrument preamp ever presented in a 500 series module.

The Radial PowerTube is an 'old school' 100% discrete class-A vacuum tube microphone amplifier intended to capture the essence of the voice or instrument while adding the rich harmonics, warmth, and character of a transformer coupled tube circuit.

Designed to fit inside the Radial Workhorse and other 500 series racks, the 'single-wide' PowerTube begins with an ultra low-noise Jensen input transformer. This exhibits near perfect frequency response while producing the warm Bessel curve Jensen is legendary for. The signal is then amplified via a select 12AX7 tube using an innovative non-radiating charge pump that supplies 140 volts to the tube to deliver the excitement and character of a high-voltage vintage tube amplifier. This feeds a class-A balanced output stage that together, can produce as much as 60dB of gain. This makes the PowerTube ideal for use with all microphones.

Features include an easy-access front panel XLR input with a safely recessed 48V phantom power switch. To optimize signal-to-noise the PowerTube is equipped with fully variable trim and gain controls. A 10 segment LED bar graph provides visual feedback and driving the PowerTube into the red is encouraged. This increases the grit, harmonic content and distortion. For even more character, activating the Air adds a slight edge to a male vocal or sparkle on an acoustic guitar. Low frequency resonance is easily tamed using the high-pass filter. For added pleasure, the PowerTube comes factory-loaded with a select 12AX7 tube along with a second Tonebone distortion pedal tube for more grit and madness.

The Radial PowerTube... the true character of a world class vintage tube preamp without the noise!

The PreMax is an all-in-one channel strip that combines a low noise mic preamplifier with a state-of-the-art 3 band equalizer to deliver exceptionally clean results each and every time it is used.

The design begins with a high performance Op-Amp coupled with Radial's unique Accustate gain control that simultaneously sets the input sensitivity and signal gain to deliver outstanding signal-to-noise at all levels. Visual monitoring is provided with LEDs for signal and overload. The preamp then feeds a traditional 3 band EQ for tone shaping. This musical sounding EQ lets you gently boost the top end for more clarity, add warmth to the bottom end, or cut back the mids on an overly aggressive instrument. A front panel switch lets you bypass the EQ and compare the pre-post effect. This is augmented with a high-pass filter to eliminate low-end resonance that can cause a track to sound muddy or lack detail. A 180° polarity reverse works double duty to either help align a stereo mic setup or enable the PreMax to be interfaced with older vintage gear that may not follow the AES Pin-2 hot convention. For safety, the 48V phantom power switch is recessed to prevent accidental turn-on which could damage tweeters or vintage ribbon microphones. When used with a Radial Workhorse power rack, the Omniport jack is configured as an instrument input and activated using a convenient front panel switch. When the Omniport is not connected, the switch acts like a microphone mute.

Designed to deliver quick, dependable results, the PreMax's integrated design eliminates the concern of matching levels between modules. You simply plug in, set the gain, tone shape and start recording. This makes the PreMax the perfect channel strip module for project studios, post production, broadcast and live recording.

The Radial Q3 is a spectacular sounding induction coil EQ that has been formatted to fit the popular 500 series format and the Radial Workhorse. It is designed to accentuate the character of a voice or instrument without introducing the artifacts and phase anomalies commonly associated with typical gyrator (resistor-capacitor) equalizer circuits.

The Q3 features four easy to use controls: top-end boost, mid-range cut, low frequency bass boost and gain make-up to offset the signal loss that occurs when using passive equalization. Each of the three EQ bands employs a 12 position Grayhill switch with a different preset curve at each position. These are carefully crafted to introduce subtle accents, huge hype and warm sounding cuts that will flatter and enthral. Each EQ setting is augmented with a miniature toggle switch that enables you to attenuate the curve for more subtle effects to deliver over 10,000 combinations of tonal bliss. And because presets are employed, it's easy to recreate favourite patches by setting the dials with 'easy to remember' 3-number combinations.

Adapted for use with the Radial Workhorse and older API Lunchbox racks, the Radial Q3 is plug-and-play easy to use. Simply feed it with a balanced line level signal and you are set to go. When connected to a Workhorse, the Omniport is assigned as an effects loop to allow various processing devices to be inserted into the EQ signal chain.

The Q3 induction coil EQ... probably the most exciting equalizer ever made.

The PreComp channel strip is a combination mic preamplifier and compressor made for the popular 500 series rack format and designed to bring greater efficiency to the recording process by simplifying the signal path and gain stage management.

The single wide module begins with a high performance preamp that can deliver in excess of 60dB to handle all types of microphones. Equipped with Radial's unique Accustate gain control, the PreComp simultaneously sets the output and sensitivity to maximize signal-to-noise at all levels. This is particularly important when recording in the digital domain where background noise can often be audible during quiet passages. A full-feature VCA compressor follows with adjustable threshold, compression ratio and gain make-up controls. The advanced compression algorithm reads the program material and automatically transitions from soft-knee to hard knee as the signal rises above the threshold. A simple slow-fast switch makes it easy to set the PreComp for either vocals or percussion.

Once connected to a 500 series power rack, connections to and from the PreComp are automatically routed to the XLRs for balanced operation. When used with a Workhorse, connectivity increases with ¼" TRS connectors and D-Subs while the Omniport provides direct patching to the preamp or the compressor, enabling the engineer to use each processor separately. Other features include 180° polarity reverse for phase matching two microphones, a high pass filter to eliminate unwanted resonance, 48V phantom power for condenser mics and an IN/OUT switch that lets you quickly compare the original uncompressed signal with the processed result.

This makes the PreComp an excellent choice for recording, broadcast and post production suites where instant control over voice and instrument is desired. The PreComp will also be a favorite for multi-channel live recording engineers where the small footprint can accommodate many input channels in a higher density rack.

The Radial Q4 is a unique equalizer that combines the warmth and detail of a pure class-A circuit with the character of true 100% discrete state-variable filters. In other words, no integrated circuits are employed whatsoever. Each full size through-hole part is carefully inserted by hand and then wave soldered to ensure optimal signal flow. This produces a level of sonic warmth and musicality that excels above the others.

Designed to fit in the Radial Workhorse and other 500 series racks, the Q4 features four frequency bands with high and low shelving at 10kHz and 100Hz and two semi-parametric mid sections that let you sweep frequencies from 300Hz to 8kHz. The two mid-bands can be further optimized by selecting either a wide or narrow Q. All frequencies may be cut or boosted by up to 12dB - affording plenty of range. A handy 'bypass' switch lets you compare the dry tone with the EQ's effect and for those equipped with a Workhorse, the Omniport is designated as an unbalanced ¼" TRS input/output connection that can be inserted into a console channel strip using a single TRS cable.

This makes the Q4 a wonderful choice for adding analog character to a voice or instrument and a natural for enhancing music program material.

The Radial EXTC™ is a 500 series module that lets you incorporate guitar effects into the realm of pro-audio recording. Just imagine… add a touch of grit to a vocal track, some wah on a kick drum, maybe flange a violin…The EXTC is a creative tool made for your esoteric-inventive side, ready to unleash fresh new sounds that will make your recordings stand out from the crowd.

And it's super easy to use: connect a line level signal from the recording system. The EXTC unbalances the signal and converts it to high impedance where guitar pedals can be inserted at will. Front mounted ¼" send & receive connectors provide easy access. Turn track on, set levels, adjust the blend for just the right amount of magic. Be prepared for instant amazement. Legalized ecstasy.

Features include Radial's award winning 100% discrete class-A guitar buffering for ultimate audio integrity, transformer isolation to eliminate buzz and hum caused by ground loops, 180º polarity reverse to keep effects and balanced signals in phase, plus a separate patch bay insert point to add studio effects into the fun.

The Radial EXTC is without a doubt one of the most innovative effect manipulating devices ever made. And it opens the door to new sounds by taking Reamping™ technology to an all new level.

Be prepared for wild & wonderful!

The Radial Shuttle is a combination effects insert and routing module that enables you to bring playback tracks, effects and other non-Radial modules into the Workhorse. This opens the doors to tremendous patching options that would otherwise require complex wiring.

The design begins with an input feed via the Workhorse or other 500 series rack. This feeds two front panel insert loops. The first is fully balanced to make interfacing with +4dB studio gear quick and efficient while taking full advantage of the lower noise affo0rded by a true balanced insert. The second loop is unbalanced for -10dB operation. This is the most common form of insert found in studio workstation environments. A third loop can be accessed via the Omniport for those that are equipped with a Workhorse. Each is equipped with an individual insert on-off selector that allows the effects to be compared.

Where the Shuttle really begins to get interesting is when using the Workhorse for real-time playback. A feed from the recorder is sent to the Shuttle where the program track can be auditioned at the same time as a new recording track without latency of any kind. One simply routes the mic preamp and shuttle to one of the 8 channels while auditioning via the main, monitor or headphone outputs.

The Shuttle makes connecting effects to your 500 series rack quick, easy and super effective..

The Radial Komit™ is a feature-rich compressor-limiter that simplifies the process of dynamic manipulation while expanding upon creative tone shaping. At one end is a super-clean compressor that delivers amazing results with single knob control. At the other, an old-school diode bridge clipping limiter goes from 'vintage to nasty'. But don't let the minimalist approach deter; the Komit provides exceptional flexibility by integrating a series of automatic functions that are both musical and intuitive. Close your eyes and listen… the Komit does the hard work for you.

The design begins with an auto-detecting feed-forward VCA that reads the incoming program material and reacts 'real-time' to the time constant. Set the 3 position attack-decay switch to slow for vocals, medium for instruments and fast for percussion. As you increase the ratio, the Komit FlexKnee™ compression dynamically adjusts the pivot point, seamlessly transitioning from soft to hard knee for more natural results. Yet unlike most limiters that are designed to be transparent, the Komit Clipper™ is designed to introduce personality to your recordings. The Clipper simulates the sound created by old-school diode bridge circuits from the early days of radio. These clip the input signal when they exceed the headroom. Same deal… only here, you are in complete control. Ten settings are graduated from mild harmonic overload to extreme nasty. Think of Nine Inch Nails.

To ensure absolute signal integrity, full size discrete electronics are employed throughout while the vintage style Hammond broadcast transformers add extra warmth to the signal path. A variable level control provides gain make-up or can be used to drive the Clipper for added distortion. Dual ballistic VU metering makes it easy to simultaneously view compression and output when making adjustments. Designed for use with all 500 series racks, the Komit can be linked for full stereo operation. When used with the Radial Workhorse, the Omniport is assigned as a key input for frequency dependent compression, de-essing, ducking or any number of dynamic manipulation effects.

The Komit transcends the complex world of dynamic manipulation with the simplicity of single dial control. Stand by for take off...

The Radial X-Amp™ is a 500 series module that lets you take a pre-recorded guitar track and send it back to amplifiers and effects so that you can tailor the sound to suit. The advantages of Reamping™ are many: when recording, the guitarist need only concentrate on the performance. Working out specific sounds and optimal mic placement can be done later. This eliminates hours of tiresome repetition while allowing the producer to adjust the character of the track as the production evolves.

Using the X-Amp is 'plug and play' easy to use. The design begins with an XLR balanced line level input located on the 500 series rear panel that feeds the X-Amp. To ensure the very highest fidelity, 100% discrete class-A circuitry is employed. The X-Amp unbalances and buffers the pre-recorded signal where it then feeds two transformer isolated hi-Z guitar level outputs. The ¼" jacks are front mounted for desk-top convenience and equipped with ground lifts to help eliminate hum and buzz caused by ground loops. Independent level controls enable you to adjust the drive going to each amp for optimal tone. Should one of the amps be out of phase, depressing the 180º quickly brings both in line.

The X-Amp Reamper™ works with guitars, basses, keyboards and even voice! You can send the signal through guitar effects pedals too. In fact the only thing holding you back is your imagination.

The Radial X-Amp…active Reamping™ made easy.

The ChainDrive is an innovative 1x4 'distro' module designed to fit inside the popular 500 series rack format. Once connected, it enables the engineer to send an audio signal to various processers, effects or remote audio systems simultaneously as a means to create innovative signal paths.

The design is simple and easy to use. One connects to the module via the power rack's rear panel XLR input which then feeds the four corresponding ¼" TRS outputs on the front panel. The unique circuit design enables both balanced and unbalanced signals to be used while also accommodating unbalanced stereo sources. Those with a Radial Workhorse may connect to the ChainDrive via the XLR, ¼" TRS input or D-Sub. Designated as an unbalanced input, the ChainDrive's Omniport input automatically converts the unbalanced signal to a balanced line so that it can then feed other 500 series modules.

Applications include sending a pre-recorded track to multiple dynamic processors to create multi-band compression, feeding a variety of effects processors simultaneously and splitting the signal to feed various guitar amps and pedals. Each TRS signal path may also be used to distribute a stereo signal such as a CD or iPod and feed it to four stereo destinations.

The ChainDrive is a unique tool designed for creative engineers who are looking to expand the sonic landscape by adding more routing flexibility than ever before!

The Radial Tank Driver is a wonderfully unique 500 series module that allows you to drive a balanced line level signal through the reverb tank in your Fender Twin amp! Yes, an affordable interface designed specifically to drive spring reverbs of all types and deliver the long trailing shimmering effect that is only possible with a true spring.

The design begins with a transformer coupled output driver with normal and high settings for new and old spring reverbs alike. Separate drive and return controls allow signal optimization to maximize signal to noise. To further tailor the tone, the Tank Driver is equipped with two tone controls that let you adjust high end shimmer and low frequency boom. (Let's face it... what else would you call it?)

Plug in an instrument and hear spring reverb with less noise and wider bandwidth than ever before. Plug a mic pre into it to add spring reverb to voice. Try it with drums to create unique sonic spaces. And since you probably have more than one amp in your studio… you will soon be using different reverbs for different tracks.

The Radial Tank Driver… Hachtung Baby!

The Radial JDX™ Reactor™ is a unique guitar amplifier interface designed to capture the tone of a 4x12 cabinet by either recording 'direct' or by interfacing the Reactor via an amplifier head and cabinet. This makes the JDX ideal for fast-paced recording environments such as film and gaming where take after take consistency is required. But don't let the high-speed production capability lead you to think compromise… the JDX is used by many of the world's leading artists including heavy metal master Kerry King of Slayer, Rascal Flatts, Radiohead and Dimmu Borgir just to name a few.

The most astonishing results are obtained when patching the JDX in between a head and cabinet. The JDX captures the sound from the head while the reactive load captures the back electro-magnetic impulse from the loudspeaker. Advanced multistage filters shape the tone to emulate the sound of a 4x12 half stack. For quick tracks and overdubs, you can plug your guitar into a distortion and then into the JDX and get a great consistent sound without having to move mics around or trying to manage variables such as room acoustics and amp levels. And with this new 500 series module, bass amps can join into the fun! Use the standard 4x12 emulation to capture the robust mid-range tone of an SVT or power-up the bottom end using the low frequency extension. Choice of 100 and 300 watt settings are available. The on-board low-pass filter gently smoothes the top end to tame overtly bright amps.

The JDX employs 100% discrete electronics and transformer isolation to create the analogue tone and the 500 series modular format makes it super easy to Reamp™ a track and warm it up. As with all Radial 500 series modules, the JDX is backwards compatible with older racks while integrating all of the new capabilities found in the Workhorse including direct connection to the mix buss and the Omniport , which in this case is designated as a direct box out to capture the live performance.

Plug & play easy to use, the JDX lets you record without having to mic your guitar amp each time. It delivers tremendous consistency from track to track while producing the realism of 4x12 half stack cabinet.

The Submix is an ultra quiet 4 x 1 mixer module designed to fit the 500 series format and enable the studio engineer to combine multiple audio stems such as line level devices and effects together and route them as needed. The Submix is also ideally suited for keyboards, samplers and drum machines where these need to be mixed into the audio chain.

The design begins with four conveniently located ¼" unbalanced inputs on the front panel. Separate level controls for each input are clearly designated for easy manipulation. These are equipped with Radial's unique dual-gang Accustate circuit that simultaneously sets the input sensitivity and the gain to maximize signal-to-noise. This enables both instrument and line level signals to easily be interfaced without the need for a typical level reducing pad. Following the Radial Workhorse and classic mixer designs pioneered by Neve and SSL, the Submix employs a traditional virtual-earth mix-buss circuit topology. This delivers exceptionally quiet performance even when several Submix modules are combined via the Omniport mix-buss input.

The single-space Submix may be used alone, or doubled-up for full stereo operation. When used with a 3-slot Radial Powerstrip, you can instantly assemble a 12 x 1 keyboard mixer for live use. With a full-blown Workhorse, you can go as far as building a 32x2 analog summing mixer or combine various modules to create unique multi-band effects.

The Radial Submix is an innovative studio tool designed to manage audio signals and open the door to creative new patching options.

The Tossover™ is a unique 500 series module that enables you to frequency-divide the audio signal path into two stems and process the high and low frequencies separately. This enables parallel processing whereby one could, for instance, process a vocal track by adding distortion and presence to the high-end while leaving the low frequencies unaffected.

The design begins with separate low-pass and high-pass filters with variable frequency and amplitude controls for each range. These are connected in series and can be used separately to split off either the bass or treble regions or used together to create a band-pass filter to enhance the mid range. This is augmented with a choice of 12dB, 18dB or 24dB per octave slopes that let you apply subtle filtering on instruments to gently smooth things out or apply a more radical filter at the cut-off frequency for more intense effects.

Either filter may be accessed via the 500 series power rack's XLR output by assigning a rear-mounted slider switch. Using the Omniport on a Radial Workhorse lets you take things a step further by allowing each frequency range to be processed separately and auditioned simultaneously. This, for instance enables you to split a bass track and process the low frequency stem using a compressor while processing the high frequencies with an effect like a tube distortion pedal. You would then mix the two stems together to create new and exciting effects.

The Radial Tossover is an innovative module that opens the door to creative options never before realizable in the 500 series world.

The Radial Space Heater 500™ is a studio-grade tube distortion for the 500 series format. Built to provide anything from subtle warmth to thick and heavy harmonic distortion, the Space Heater 500 is both useful and fun!

Designed for use in the Radial Workhorse or any other 500 series rack, the Space Heater is built around a 12AX7 tube. First, a drive control lets you determine the amount of signal passing through the tube. Next, a 3-position heat switch allows you to apply 35, 70 or 140 volts at the plate to change how the tube reacts to the signal. At the low 35V setting the tube is starved for voltage which causes the tube to break up at a very low volume. The middle 70V setting is a great starting point and allows the tube to handle more level before breaking up to a moderate distortion. At 140 volts, maximum voltage is applied to the tube producing slight saturation and warmth. Sweepable high-pass and low-pass filters can be assigned 'pre or post' tube, allowing you to focus the tube effect on a particular frequency band or cause the tube to react in a different way. Finally, an output level control provides attenuation or boost through an oversized Jensen transformer specially selected for its big bottom end and vintage character.

Enhancing a snare with a touch of distortion can increase presence without losing dynamic range. Blending in some overdrive to a bass track can add clarity without overpowering. Adding distortion to a vocal track can add character and sizzle to cut through the mix without over-compression. The Space Heater 500's amazing 'adjustability' allows it to be used as a subtle effect or as a high gain monster. And no matter your approach, it is sure to find its way on nearly everything you record!

The Space Heater 500… to infinity and beyond!
