| Content | If there’s one style of preamp that professional engineers would unanimously agree has defined the tone of pop/rock records for decades, it would most definitely be the venerable '73-style of mic pre. '73-style preamps have been massively used in recording and live applications for many years and are still considered to be the “Holy Grail” of preamp choices today. The Warm Audio “WA73 Family” consists of single and dual channel '73-style preamps (with & w/out EQ), that each pay careful homage to British audio history.
When we at Warm Audio decided to release the WA73-EQ it was imperative that it met vintage expectation in both design and performance. The tone and sweet character that vintage '73-style mic preamps impart is so unique and familiar, that we had only the pure desire to release sonically accurate reproductions. After years of R&D, intense research and countless hours of auditioning, the WA73-EQ was born!
The WA73-EQ is a “Desert Island” boutique preamp, but it can also be classified as a studio and live work-horse. Classic '73-style preamps are known for being versatile tools that work with all kinds of microphones from Condenser, to Dynamic, to Ribbon. The WA73-EQ equally shines on all types of microphones and sources including; vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, and even as a tone shaping tool to run partial or complete mixes through. With 80dB of gain and a fully discrete Carnhill Transformer balanced signal path, there’s no recording, mixing or engineering task that the WA73-EQ can’t handle.
Enthusiasts unequivocally get excited about the components used in classic '73-style British preamps. The signal transformers are a common topic of conversation. Vintage units used various versions of transformers throughout the years, but the most coveted were the earliest versions. These are regarded as the most desirable choice due to their fluid and forgiving nature. They saturate sweetly when pushed, and have been known to make engineers cry when they hear how beautiful their mixes sound through them!
Warm Audio worked closely with Carnhill Transformers of Cambridgeshire, UK, to design faithful reproductions of these most coveted, early version transformers. We at Warm Audio have not yet heard a modern day '73-style preamp sound as sweet and musical as does our WA73-EQ with these beautiful custom Transformers.
An important part of the classic British circuits not often discussed are the different styles of capacitors and output transistor used. We found it important to maintain integrity to the original design by using tantalum and polystyrene capacitors in the signal path and an output transistor choice that is much smoother in the high gain settings than what is typically found in modern '73-style reproductions.
A great sounding '73-style circuit should be just as reliable as it is great sounding. The complex dual concentric switch potentiometers in the EQ sections of the WA73-EQ are made in the UK by Blore Edwards who manufacture military spec switches and potentiometers. The use of Blore-Edwards components is no small inclusion for a '73-style preamp-eq in this price range.
Classic '73-style preamps were often hand-wired and so is the WA73-EQ! Guru’s claim that a portion of the sought after classic British tone can be attributed to the hand-wired nature of the build. The WA73-EQ is hand-wired and hand assembled, including the pcb components that are all populated by hand.

| Firmly rooted in six decades of console design experience, the 5057 Orbit gives your mixes the legendary tonality, power, and wide-open soundstage that only Rupert Neve’s class-A analog summing can provide. Coupled with Rupert’s famous custom audio transformers and Silk Red & Blue circuitry for variable harmonic saturation, the Orbit launches sterile in-the-box mixes to new heights of tone, depth and clarity – without compromising the recallable convenience and repeatability of your DAW-based workflow.
When you push a mix buss and output transformers towards saturation, the non-linear, musical harmonics that occur are what truly glue a recording together and bring it to life.
Rather than using an external summing solution that offers little more than an ultra-clean representation of the in-the-box experience, the Orbit provides the extraordinary richness, harmonic complexity and depth that only a Rupert Neve console can bring to your mixes.
The Orbit utilizes a highly custom output transformer configuration originally developed for the acclaimed Shelford Channel, which provides both a Main Output and a -6dB Output – the latter of which enables you to fully drive the Orbit to achieve more transformer harmonics without clipping the next device in the chain. This unique transformer drive is a hallmark of the sound of Rupert Neve throughout the years – and the sound of countless classic hit records.
Classic Sounds on Demand
Every mix demands its own treatment. In addition to the choice of outputs, the continuously variable Texture control with Silk Red and Silk Blue modes gives you complete control over the harmonic density and tonality of your mix – or lets you keep it utterly pristine and uncolored.
The Silk Red mode accentuates transformer saturation in the high and high-mid frequencies to amplify the vibrant midrange harmonics associated with Rupert’s vintage equipment, while Silk Blue accentuates saturation of the lows and low-mids to add thickness and weight to any source – especially useful for “thin-sounding” mixes. Unlike EQ, these Silk & Texture controls saturate the output transformers, and add highly musical harmonics to the source material according to the amount of Texture applied.
Drive the mix buss hard, choose your Silk flavor, and crank the Texture knob for a rich, saturated, vintage vibe – or disengage Silk entirely for clear, wide-open sonic beauty. The choice is yours.
Build your Dream
While the Orbit is an extremely effective tool on its own, multiple units can be combined through the Buss Link for a higher channel count. The 5057 Orbit can also be used as a building block in an expandable summing system utilizing the 5059 Satellite for flexible summing & routing, and the 5060 Centerpiece for additional mixing and monitoring features.
These units create the core of a world-class analog modular console system rivaling any traditional large-scale studio setup.
Channel Separation and Accuracy
With precisely fixed channel levels and accurate mix buss attenuation via high-quality stepped switching, the Orbit’s purist signal path has vanishingly low crosstalk, and channels matched to within +/-0.1dB. This provides your mixes with the widest and most accurate stereo image, the greatest depth, and the most direct signal path, allowing you to hear every single detail of your mixes.
DAW Based Recall without Compromise
Frequent recalls can be a challenge for modern mix engineers. The Orbit’s elegant simplicity and fixed level accuracy provides rapid, repeatable DAW-based recall from mix to mix, while adding the rich, unrivaled sound quality of Mr. Neve’s class-A transformer-coupled mix buss.

- Converts balanced line level signals to unbalanced
- Stereo signal path with set & forget level control
- Transformer isolated to eliminate hum & buzz
- J-Iso features Jensen™ transformers for optimal signal path
The Radial J-Iso and Pro-Iso are stereo line isolators designed to convert a professional +4dB line level balanced signal to an unbalanced -10dB consumer level device. This enables you to take the balanced output of a mixer and feed a consumer level recorder or audio input on a computer.
J-Iso Part # R800-1025: The J-Iso employs a premium Jensen transformer for optimal signal transfer to minimize distortion and artefact. Full bandwidth performance makes the J-Iso ideal for music production.
The passive design begins with 100% discrete components throughout. A set & forget level control lets you attenuate the input signal to prevent it from overloading the destination device. Output connections include a stereo pair of ¼" connectors, a set of RCAs and a mini 3.5mm (1/8") for interfacing to a mini recorder or lap-top computer. Transformer isolation helps eliminate hum and buzz caused by ground loops while eliminating stray DC currents from flowing.
Construction begins with 14 gauge steel throughout utilizing Radial's unique bookend construction. This creates a protective zone around the connectors and controls for added durability. The steel construction also assists by shielding the transformers from outside magnetic fields. Inside, the J-Iso features an innovative I-beam skeletal insert that makes it virtually impossible to torque the PC board. This reduces potential stress which could cause premature solder joint failure.
Designed for full range applications, the J-Iso combines exceptional signal handling with the type of durability that has made Radial famous. Signal Processors | Radial X-Amp Active Reamper
- Active Reamp® with two outputs
- 100% discrete class-A signal path
- Transformer isolated to eliminate noise
- Variable 'set & forget' level control
The Radial X-Amp is an active Reamper™ that allows the engineer to play a pre-recorded track back through guitar amplifiers and pedals. This opens the door to explore new musical sounds and spur on the creative process so that your recording stands out.
Using the X-Amp is easy: start by recording a dry track using a high quality direct box like the Radial J48. Send the new track from your recorder via the X-Amp to your guitar amps, effect pedals or combinations thereof. Once the basic track has been recorded, replacing or adding tracks can be done well after the session player has gone home. This eliminates tiresome repetition and assures a fresh vibrant performance on the final recording. Furthermore, by driving two amps at the same time, new sounds and textures can be created while allowing you to make artistic decisions as the recording progresses.
Following the critically acclaimed Radial JD7 Injector, the X-Amp employs a unique class-A circuit design that has been optimized for use with guitars. Features include balanced line level input with LED peak indicator and level control, class-A circuit topology for optimal reach and frequency response, a transformer isolated output to eliminate hum and buzz caused by ground loops, a 180º polarity reverse switch to bring both amps into phase, and a dual ground lift switch for noise-free operation.
As with all Radial products, the X-Amp is built like a tank to provide years of trouble-free performance. An internal I-beam skeleton provides maximum protection against external stress which could cause solder points to fail. This is supplemented with an innovative bookend design that creates a protective zone around the switches, potentiometer and connectors. A full bottom no-slip pad performs double duty by keeping the X-Amp from sliding around when placed on a vibrating amplifier while also providing electrical and mechanical isolation. Reamping works equally well on bass, keyboards, drums and voice. Once you start Reamping, you will never record any other way.
