REDOX - Stereo Reverb

Stereo Algorithmic Reverb Processor

Price and Availability | REDOX Manual | Sounds | Videos

Reverb is the key to bringing out the best is so many sounds, and this is especially true with electronic music production where we often start off with excessively dry signals. REDOX is designed from the ground up to be a companion for electronic musicians and producers looking for a universal reverb solution for both studio and stage. With a fast and intuitive user interface, great metering, and a wide range of algorithm types, REDOX is ready to impressive you with its sonic flexibility.

REDOX is part of our new line of power desktop music machines designed to offer studio-grade effects in rugged, portable units. Designed to complement synths, drum machines, DJ tools and computer-based audio interfaces, REDOX integrates perfectly into the modern studio or performance setup.


Designed from scratch, the REDOX reverb algorithms offer both classic and modern sounds that use a number of proven reverb structures to create subtle and rich reverb sounds to suit a variety of uses including synths, drums, vocals and more. All effects allow their filter and size controls to be adjusted in real-time from the front panel, as well as an additional parameter based on the algorithm chosen.

MOD Effects

REDOX gets even better when you add MOD effects. These additional effects are like having a separate effects processor strapped around the reverb unit. Signals can be processed before and/or after the reverb in the signal path. Effects such as phasing, flanging, vibrato and panning and various distortions can be used to create special sounds. And special built-in looper lets you create textures that can continue feeding the reverb input while you perform new material. The MOD and reverb effects can be separately set up, but saved together in a single preset. This lets you create complex setups that you can call up quickly.

USB Power and MIDI Control

By using the latest technology REDOX has been created to run off USB power with just over 1W of power usage. Take you studio on the road or to a park without worrying about bringing the correct power adapter. You can even plug multiple units into a multi-output USB power supply. Or connect REDOX to your computer and control over MIDI. But despite its tiny power consumption REDOX still has a proper audio section with high quality TI op amps designed to interface with most electronic music gear flawlessly.

Built-in DIN MIDI ports allow REDOX to fit into your sequencer and MIDI setup with all parameters being controllable in real-time via MIDI. You can change presets and adjust parameters via CC messages. The built-in hardware THRU port offers a low-latency copy of the MIDI IN signal to pass to other units.

Powerful Core1™ Technology from Kilpatrick Audio

We use the best technology that we can fit into our products, and in the case of REDOX that means something completely new! Our Core1™ hardware technology uses the latest Digital Signal Processor (DSP) chips, efficient power management and high-end analog audio components. In addition, our companion software platform helps us develop better algorithms and make the most of the powerful DSP hardware.
