Description

At the heart of the ISA range is the microphone preamplifier with its Lundahl input transformer – essentially the same circuit, based on the original ISA110, that has been used for 30 years in successive Focusrite designs. The input transformer imparts a special character to the sound that can’t be truly emulated in any other way: inseparable from the microphone itself, the transformer input stage is ideal for use with classic microphones. But this mic pre has a twist the original didn’t have, which makes it far more versatile: four carefully-selected impedances allow you to match microphone to input in different ways. Bring out the character of a classic mic or emphasise a special feature, or go for a totally transparent, modern sound – it’s up to you.Whether you’re an artist, engineer or producer, you’ll appreciate the versatility of the ISA One, with its front-panel DI input. The DI includes low/high impedance switching and an amplifier output, and its own feed to the optional A/D converter and separate rear-panel XLR output.

ISA series transformer-based preamplifier
Encased in a rugged and portable chassis, ISA One offers the classic Focusrite microphone preamplifier at its lowest cost to date.

Flexible independent DI channel
ISA One is ideal for both engineers and demanding performers alike, featuring independent gain control, an output for routing to an amp, an independent XLR output on the rear and routing to the optional A-D converter.

Switchable impedance
Choose one of four carefully selected input impedances, including the original ISA110 setting, to suit any microphone.

Headphone output with volume control
ISA One can feed either a sum of the two input to the headphones output, or an external stereo cue mix (such as a stereo feed from an interface) via two TRS jack inputs on the rear of the unit.

Dedicated insert point
Allows you to place extra processing between the preamplifier or DI and the optional converter, such as an EQ or compressor.

Optional stereo 192kHz A-D converter
You can chose to upgrade your unit with an optional digital card that delivers the best A-D performance in its class (dynamic range of 118dB). Alternatively, the ISA One Digital comes with the A-D converter as standard.

Lundahl LL1538 Input Transformer
The original mic transformer used in the original Red modules helps to provide the unique sound and performance of this groundbreaking design.

Backlit VU meter with variable calibration
ISA One has a moving coil VU meter with variable calibration to suit analogue and digital recording media, alongside two six-LED peak meters; inputs can be metered either pre- or post-insert.

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

  • 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

As with ELI’s other signal processors, the Lil FrEQ Equalizer takes a somewhat unique approach to its job. Instead of daisy chaining several equalizers and frequency processors, we combined most of the sound sculpting tools an engineer needs into a compact single rack space box, while still offering the highest performance of any design in its class. Eight Sections of Processing There are eight sections of processing – what other EQ offers that? Even better – in addition to a master bypass, each of the Lil FrEQ’s sections features its own dedicated bypass switch, letting you instantly A/B the effect of each section as you adjust and fine-tune them. HIGH PASS – The High Pass section is a really easy to use sharp filter that cuts all content below one of eight preset frequencies from 30-330 Hz. This filter is very steep and has a special shape that prevents frequencies from thinning out just above the cutoff point. The corner frequency is selected using up/down buttons, and indicated by LEDs that glow softly when the section is bypassed, and brightly when the section is engaged. HIGH & LOW SHELVING – These two knobs function similarly to the familiar “bass and treble” tone controls found on many consumer audio playback systems; however, these are designed to a much higher performance standard, providing exceptionally smooth and musical boost and cut on the high and low frequencies. PARAMETRIC EQ – The Lil FrEQ has four sections of fully parametric EQ (LF, Lo Mid, Hi Mid and HF), with each section featuring individual gain, bandwidth (Q) and frequency controls.  It may be the cleanest parametric EQ section ever produced, operating below .0007% THD (Total Harmonic Distortion) even at extremely high audio levels. Try finding those specs anywhere else! DS (DYNAMIC EQ) – The DS section provides the highest performance, easiest to use, and possibly most natural sounding “De-esser” ever built.  This powerful tool combines tunable filters with a compressor-like circuit that can help contain and control excessive high frequency content such as sibilants or other sharp transients, especially in the absence of other lower frequency content.  It can also function as a one of a kind soft knee High Frequency limiter, which is one of the main things responsible for the Lil FrEQ becoming the go-to vocal EQ for engineers everywhere.  It has been used on many acclaimed albums and major live performances all over the world, becoming the “go to” EQ for key tracks like lead vocals, snares, and bass.  There are now dozens of hit record vocals that were processed thru the Lil FrEQ. Frequency Response: 5 Hz to 140 kHz on transformerless inputs and outputs. Transformer output 10Hz to 110 kHz. Dynamic Range: 120 dB from maximum output (.1% clipping) to minimum output. Greater than 110 dB signal to noise. Distortion: Ranges between .00056% and .005% depending on mode and settings. DS section has THD < .005%. I/O: DC coupled inputs and outputs and one transformer coupled output. Dynamic Time Constraints: Attack is approximately .5 ms. Release .04 sec fixed internally. Power Consumption: 15 Watts Max. Metal Chassis: single height 1.75″ high, 10″ deep, 19″ wide.
