- 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 | This item is in excellent working condition and barely used.

Please Note: The item displayed in the images may not be the actual item you receive. | In today’s modern age of digital recorders, DAWs and software plug-ins, Mike-E is the ultimate solution for getting a clean and strong, yet warm and musical signal into the box…and it couldn’t be easier to work – its front panel layout is so straight ahead that even inexperienced engineers will have no problem moving around on it right away.
When the engineering team at Empirical Labs sets out to build a microphone preamp, you can be sure it’ll deliver spectacular sound, be effortless to work, and will provide features unlike any other device in its class. To that end, we proudly present Mike-E, a high performance transformer-coupled mic preamp with a noise floor far below any microphone’s self noise, combined with a one-of-a-kind compressor/saturator circuit that delivers classic knee compression as well as versatile tonal ‘coloring’ that can replicate many of the best characteristics of vintage analog recording equipment.
Mic Preamp
The Mike-E features a super low noise transformer input amplifier section with the gain under precise digital control. The signal to noise far exceeds any microphone in existence. Having used many mic preamps over the years, we’ve implemented a unique stepped gain control that should be impervious to the normal flakiness that age causes to pots and detented switches. A “Bad!” LED indicates when the input signal is overloading the circuit.
CompSat
The CompSat’s unique circuitry sets the Mike-E apart from all other mic preamps.
- SATURATOR – a multi stage soft-clipping circuit. At lower levels, a triode-type saturation affects the signal. As the level increases, a second unique clip circuit starts to more severely flatten out the peaks.
- COMPRESSOR – based on ELI’s world famous Distressor, but with other characteristics (including a much longer attack time). Preset ratios include: 2:1, 4:1, 8:1…and, of course, Nuke.
- EMPHASIS – a two-stage circuit that boosts and soft clips high frequencies before the CompSat™ circuit, and then cuts the frequencies after it. Emphasis has the added perk of improving signal to noise, and is the reason analog tape decks used emphasis to begin with.
Frequency Response: 3 Hz to 200 kHz on (No CompSat). CompSat is 3Hz – 150Khz. Optional Transformer output is 6Hz–80kHz.
Signal to Noise: 130 dB signal to Noise.at 40dB gain. Maximum output is +28dBu.
Distortion: Ranges between .0006% and 15% depending on mode and settings.
I/O: Transformer coupled Input, Active and Transformer Outputs available. High quality audio caps used internally.
Impedance: Input Impedance is above 600 Ohms at all frequencies, transformer coupled. Output impedance is less than 38 ohms. Instrument In Impedance is 332K Ohms.
Attack/Decay Range: .9 – 70mS attack. .15 – 1 Sec.
Power Consumption: 15 Watts Max.
Metal Chassis: single height 1.75″ high, 10″ deep, 19″ wide. | The vintage EQ tones you know & love.
The 551 is the only equalizer for the 500 Series actually designed by Rupert Neve. Featuring 3 bands of EQ inspired by Mr. Neve’s most prized vintage designs, along with custom-wound inductors, transformers and class-A gain blocks, the 551 brings the thick, powerful lows and sweet highs of Rupert’s classics to the 500-Series format.
The “Best-Of” EQ
The 551’s 3-band, custom-tapped inductor EQ was inspired by our favorite elements of Rupert’s vintage EQ designs. The low frequency band is designed to produce a creamy, resonant bass response similar to a vintage 1064 – but unlike the vintage modules, the LF band on the 551 can be used as either a shelf or a peak filter, adding punch, dimension, and control to your low end.
The midrange band is based on that of the 1073, ideal for sweetening vocals and instruments while bringing them forward in a mix, and its proportional “Q” response makes it well-suited for minimizing problematic frequencies. The high frequency band is a hybrid vintage / modern design, blending inductor circuitry with capacitor-based topologies to achieve vintage tones with enhanced control. The High Pass filter is a 12dB/octave design with a fixed 80Hz frequency, and can be used in tandem with the low frequency EQ to add low-end presence without clouding the source material.
As with Rupert’s most prized classic designs, each EQ section uses low-feedback, class-A discrete electronics to prevent low-level artifacts and harshness from detracting from the tonal shaping. However, this new circuit is a decidedly modern design with updated techniques and components that were simply not available 50 years ago, and is definitely not a “clone”.
What Are Inductors?
Inductors are wires wound around a coil that provide a form of frequency-dependant resistance. When they saturate, they bring out beautifully musical harmonics that give your tracks the smooth, polished sound that has made Rupert’s consoles and equipment so desirable for over fifty years. This is what makes them different from capacitor-based EQ designs, which do a great job at surgical equalization. But inductors provide the tone.
While it is certainly possible to create a functioning EQ using off-the-shelf inductors, we choose to use our own custom inductors for the 551. This attention to detail in controlling variables such as the winding and core materials in relation to the surrounding circuitry allows the 551 to capture the vitality and personality of Rupert’s classic designs.

| Arguably the coolest and most unique device in the Empirical Labs arsenal, the FATSO (Full Analog Tape Simulator and Optimizer) is a digitally controlled analog device that gives musicians and engineers easy access to many of the desirable characteristics exhibited by older tube and Class A electronics and magnetic tape mediums. This two channel audio processor musically integrates frequencies and transients, increasing the apparent volume while keeping tight control over peak levels.
With the FATSO, recording studios and audio production facilities can enhance and soften the sound of Hardware Digital Recorders (HDRs) and Digital Audio Workstations (DAWs). Mix engineers will have the option not to have to use bulky, expensive analog tape recorders to get the warmth and sweet high end they’ve come to rely on for so many decades. Owners of DAWs and HDRs can finally put a stop to complaints about the coldness and brittle edge of their mixes and instruments. Even audiophiles can benefit from the FATSO, bringing back the warmth and ambience of LP’s and tapes to their CD players and other digital reproduction mediums.
The FATSO Goes to Eleven
ELEVEN is a new compressor for the FATSO, replacing the old GP Ratio, and emulates the famous UREI 1176LN in 20:1, with the slowest attack, and fastest release. This 1176 setting has been used on countless hit records through the decades. With the slower “1176” attack, the transients keep the dynamics present, while the high ratio, can radically limit the dynamic range of any source, making it present and sitting in a nice little place in your mix. One can slam it, or just touch it with a few dB of compression. You will find it great on Vocals, Bass, acoustic guitars, drum room mikes, pianos etc. Click here to find out how to upgrade your EL7 to an EL7X.
Four Types of Processing
- Harmonic Generation and Soft Clipper (Distortion Generation) – this class A circuit gently rounds the peaks like saturated tubes or tape.
- High Frequency Saturation (Warmth) – a one-of-a-kind dynamic low pass filter which softens high frequencies when they “pile up” on a source.
- Transformer & Tape Head Emulation – a simulation of the effect of input and output transformers of older devices, which adds the low frequency harmonics that characterize them, as well as analog tape..
- Classic Knee Compression – your typical automatic leveling device found on just about every instrument and vocal track as well as on the overall buss, done Empirical Labs compression – smooth and sweet, but in your face!
Universal Audio's FATSO Emulation
Endorsed and scrutinized for accuracy by designer Dave Derr of Empirical Labs, Universal Audio has painstakingly recreated the FATSO Jr. in this highly anticipated UAD Powered Plugin, capturing the sonic nuances of the original hardware. As part of the FATSO Powered Plugin, UA has also worked closely with Dave Derr to model the original concept of the FATSO, the FATSO Sr., with attack, release, and threshold compressor controls, among other features not available elsewhere.

Metal Chassis: single height 1.75″ high, 10″ deep, 19″ wide. | 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.
