RS-120 Comb Filter
Voltage Controlled Comb Filter
- 10 mA +12V
- 10 mA -12V
- 0 mA 5V
- 2.5 inches depth
- 12 hp
The filter is based on a bucket-brigade-device delay with very short times that clearly changes the phase of the signal. The feedback of this delay is used here as a resonance parameter that goes up to self-oscillation.
There are two audio inputs with level control. Unity gain is reached at the pot´s position 4, beyond thsi point the filter will be overdriven. A control sets the delay time from 2.5ms to 25ms and in addition there are two CV inputs for controlling delay time, one with fixed 1V/oct and a variable one.
CV: one input with 1V/octave and one variable input with attenuator.
Audio: 2x signal input, 1x signal output
