"Great working condition, this filter/processor comes with manual and power cord. Read below to learn about this unusual channel strip.

Features
- fully analogue integrated modular sound-design-machine/channel-strip

- two different 4-pole super-sonic multimode VOLTAGE CONTROLLED FILTERS (VCF's) with 12 characteristics each (lowpass, highpass, bandpass, notch, allpass) and with an extreme tonal range

- completed by an easy controllable superb COMPRESSOR,
a sweet sounding 2-way spectral DISTORTION unit and a final VCA
- all surrounded by a lot of very wide range voltage controlled MODULATORS (high speed VC-LFO, 2x high range VC-AHR (Attack-Hold-Release) - ENVELOPES, super fast RMS-VOLTAGE-FOLLOWER (logarithmic/linear scale), a S&H and a NOISEGATE.
- the very fast high precision AUDIO-TRIGGER is able to derive absolute reliable triggers for gating, synchronizing and controlling other modules like ENV's, LFO, S&H or external stuff - capable to produce perfect in-time rhythmic and synchronous modulations according to your music data input - very sensitive and independend on the input level.
Modules & Features:
-Input Amplifier (0db/+20db)
-Automatic Softknee Compressor (Attack/Release times: 20 ms/125 ms or 40 ms/250 ms)
-2-way spectral Distortion with two change over frequencies (96 Hz/ 1050 Hz)
-quick Signalflow change (parallel/serial/anti-serial mode of VCF1, VCF2, Distortion)
-2 x VCF with 12 filter functions each (6xlowpass, 2xhighpass, 2xbandpass, notch, allpass)
-VCA
-VC (Voltage Controlled)- high speed LFO
-Sample & Hold (S&H)
-true RMS Voltage Follower (linear/logarithmic (db-linear) scale)
-2 x VC-(Voltage Controlled)-Envelope Generators (Attack/Hold/Release or Attack/Release)
-dynamic (level independent) Audiotrigger
-Noisegate
-Bypass
