 Rack-24 Rack Mount System

Three 19" 5U tall rack mount frames hold an excellent array of modules including 3 oscillators, 2 envelope generators, 2 amplfiers, and our State Variable Filter. Use the instrument interface to process signals from guitars and microphones and use the MIDI interface to connect to your computer or keyboard. Also included is a noise source, sample and hold, ring modulator, slew limiter and more. Two blank panels allow expansion with another oscillator or our Q150 Ladder filter.

Calibrated Range Switches
Increase range switching accuracy on your Q106 oscillators from 1% to .1% by adding a Q106CRS to each. This is helpful for fast accurate range switching in real-time without a need to fine tune.

Ladder Filter
The Q150 Transistor Ladder Filter is based on Bob Moog's famous design.

Add the Q130 Clipper/Rectifer to beef up oscillator outputs, tweak modulation signals, and add distortion to waveforms.
