Description

The Radial J+4 is a stereo interface designed to accept unbalanced low output level devices such as instruments, computers or CD players and boost the signal to a balanced +4dB level for easy manipulation in professional environments such as broadcast, recording studios and live touring.

The design begins with 100% discrete components for optimal signal transfer. Careful attention has been paid to eliminate noise by combining the advantages of active signal buffering with transformer isolation. The J+4 delivers better than 95dB signal to noise while ensuring hum and buzz caused by ground loops along with spurious noise from clocking does not pollute the signal path. For ease of use, controls have been kept to a minimum. This includes a stereo level control, a high pass (low cut) filter and ground lift. The choice of input connectors include a stacked set of ¼“ jacks for DJ mixers or keyboards, RCAs for CD players and a mini 3.5mm for iPods.

As with all Radial products, the Radial J+4 is built tough to handle the extreme rigors of professional touring. A unique 14-gauge steel I-beam inner frame ensures the sensitive PC board will not be subjected to outside stress which could potentially cause solder joints to fail. An innovative book-end outer shell creates protective zones around the controls, switches and connectors to further improve dependability while a full bottom no-slip pad provides both mechanical and electrical isolation.

The Radial J+4 balanced line driver delivers exceptional sonic performance, plenty of headroom and ultra low noise making it the ideal companion for today’s more demanding professional audio systems.

  • 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. The Radial X-Amp… the active Reamp® for professional recording engineers.
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.

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.

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. Frequency Response: 2 Hz to 60 kHz in clean audio mode (+0, -3 dB). Dynamic Range: 110 dB from maximum output (20 %THD soft clipping) to minimum output. Greater than 100 dB signal to noise. Distortion: Ranges between .06% and 20% depending on mode and settings. I/O: DC Coupled input and outputs. Compressor Time Constants: Attack range 1ms – 60ms. Release range .05sec – 3.5 seconds. Attack and Releases are fixed by the compression type selected. Power Consumption: 15 Watts Max. Metal Chassis: single height 1.75″ high, 10″ deep, 19″ wide.
The Suhr Reactive Load delivers a simple solution to capture all of the warmth, and dynamics of your sound, without the hassle of miking a speaker cabinet during a live or recorded performance. The Reactive Load takes the place of your speaker cabinet in your signal chain. It provides an 8Ω load for your tube amplifier (maximum 100 watts), and produces a balanced and unbalanced signal that interfaces with recording devices, effects, and power amplifiers. The Suhr Reactive Load is the perfect link between your amplifier and computer audio recording interface. You can use the Reactive Load with your existing library of speaker impulse responses (IR) for the most realistic direct recording experience possible. Traditional resistive load boxes will safely load your amplifier, but they also alter the tone, dynamics, and response of your amplifier. Real speakers do not have a fixed resistance across the entire frequency spectrum. Real speakers are reactive. The impedance curve of the Reactive Load has been painstakingly tuned to react like a speaker. Your amp will never know the difference. The Reactive Load is dedicated to being the absolute best load box possible with zero compromises, and therefore does not include speaker emulation. You can use the Reactive Load with your speaker-sim or impulse response of choice, and benefit from the natural response, dynamics, and touch sensitivity of your amp. The Suhr Reactive Load features a balanced or unbalanced line level output. The INPUT is optimized for the 8 ohm output of your amplifier and the THRU jack can be connected to a physical speaker cabinet. If a physical cabinet is connected to the THRU jack, the Reactive Load’s internal load is bypassed and the amp will see the load of the physical cabinet. SPEAKER INPUT IMPEDANCE: 8 Ohm DI / LINE OUT LEVEL: +4 dBu at 7 watts input, maximum level setting BALANCED LINE OUTPUT IMPEDANCE: Less than 6KΩ UNBALANCED LINE OUTPUT IMPEDANCE: Less than 6KΩ MAXIMUM RECOMMENDED INPUT POWER: 100 Watts RMS ROHS COMPLIANT: Yes DIMENSIONS: 8.8" (W) x 8.9" (D) x 3.6" (H) WEIGHT: 6.6lb
