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.

Originally developed for the dynamics circuit of the acclaimed Shelford Channel, the 535 Diode Bridge Compressor captures the soul of Rupert Neve’s original 2254 compressor while providing modern updates including advanced timing control, significantly lower noise, fully stepped controls throughout, and internal parallel processing capabilities. What is diode bridge compression? Where the VCA compressor found in the Master Buss Processor provides unmatched clarity, the weighty, harmonically rich tonality of diode bridge compression can be essential in pushing key sources like vocals, electric guitars, bass and drums to the forefront of a mix. By understanding the limitations of vintage units like the legendary 2254, painstaking effort was taken to reproduce the unique tone of these classics while improving the noise floor & accuracy, expanding inflexible time constants, adding full wave sidechain detection for improved dynamic response, and widening the range of threshold and ratio controls. Delivering the powerful sound of these iconic designs with enhanced flexibility for the modern age, the 535 Diode Bridge Compressor is a dynamic tool equipped to make a bold statement on virtually any mix or track.

Proven reverberation classic for the future With the VSR 3.2, we happily rely on the proven old mechanical way to create reverberation. Rightly, because the used reverberation spring by AccuBell (formerly Accutronics) creates that magic 60's reverb which is slightly metallic and dense at the same time. Just like it predecessors, VSR 3.2 has a straight-forward and honest approach: signal in - spring reverb - vintage sound out. VSR 3.2 is equipped with an equalizer that is exactly adapted to the springs' frequency response. In addition, there are controls to mix the dry and effect signal as well as controls for the input and output level. This way, VSR 3.2 simply exactly does what it was designed to do. Designed for every situation Although using a large spring (type 9), VSR 3.2 fits in a 19" housing with one rack unit – minimal space requirements. Thanks to its extremely solid chassis, VSR 3.2 is a reliable vintage-effect that cannot only be used in a controlled studio environment. On the contrary, it also serves fine when being used in straining live situations. VSR 3.2 grants your sound an elegant touch of "good old times". Its simplicity makes it an unbelievable versatile companion. Inputs

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
