| Content | 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.

Weight: 8.6 lbs | Imagine having the power and flexibility of the OP-Z sequencer available to any other music equipment. Now you can, with the new oplab module - the magic link between OP-Z and the rest of the world. The oplab module is the first hardware expansion module for OP-Z. once mounted in the back of your OP-Z, you can use it to connect to any equipment using standard cv and gate, such as the pocket operator modular or any other modular system. It features three cv outs and one gate out, all programmable and playable from OP-Z. have your wall of modules sequenced from the palm of your hands. Use the po sync out to unleash the power of your regular pocket operators and have them play in sync with the rest of your setup. Even connect standard midi devices, using midi over 3.5 mm jack or the included midi over din adapter cable. Oplab features both midi in and out ports as well as trig in and out for other synthesizers and sequencers. | Condition: Item is subject to minor cosmetic imperfections.

- 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 | Effective against boredom, supporting creative sound design
A unique team play of spring reverberation, analogue multimode filtering, distortion and VCA, modulated by an ultra fast LFO and an envelope that can be triggered in flexible ways – Retroverb Lancet offers a comprehensive arsenal of many-sided effects for different applications. The spectrum by far surpasses classic reverberation, filter sweeps or overdrive because you are able to tweak and bend any parameter fast and intuitively to your liking.
Retroverb Lancet will change the way you work with effects. It becomes part of your sound engine, fires it up and will end up as essential part of your sonic signature.
Source of effectiveness
We designed Retroverb Lancet in a way that it can perfectly handle signals of any kind: Guitars, basses, synthesizers, organs or microphones. On top of that, Retroverb Lancet allows you to create percussive sounds using its crash function.

In link mode, the compressor generating the greater sidechain voltage (resulting in higher amounts of compression) will control the compression of both audio signal paths to maintain proper stereo center image while compressing. Note: it is advisable to always audition the unlinked sound as well, to decide if the benefit of a constant stereo center image is worth the potential trade-off of reduced left / right independence in the stereo field.

SIDECHAIN HPF
- The S/C HPF switch allows the user to insert a 12dB/octave 150Hz high-pass filter in the compressor sidechain. When this filter is engaged, the compressor will be considerably less responsive to information below 150Hz. For example: if used on a drum kit, the low end of the kick drum would have less proportional effect on the compression than a snare drum or cymbals, since a significant portion of the kick drum’s dynamic energy is focused below 150Hz.
LEVEL AND GAIN REDUCTION METERING
- These two LED meters provide accurate representations of both the output level of the compressor and the amount of gain reduction being applied to the input signal.
