cwejman res-4 four band voltage controlled parametric resonator price : $799.00

the res-4 is a modified vceq-4 with combined four band pass filters in to two outputs; band pass and notch. the band pass is a sum of all four filters (res1, res2, res3 and res4) in phase and the notch is a sum of filter1 (res1) + fiter3 (res3) in phase and filter2 (res2) + (filter4 (res4) inverted. the result of these two outputs is a different frequency responce with differently positioned notches for the band pass and the notch.

all parameters (peak frequency, bandwidth and level) can be controlled manually (knobs) or by cv inputs, individually for all four resonators. additionally, peak frequencies and levels, for all four resonators, can be controlled by linked cv inputs (master cv freq and level).

total frequency range: 5hz to 22khz
bandwidth (bw): 0,6 to 0.02 octaves at 3db point
level: 0 to 20db (bw=0,6) and 35db (bw=002)

control inputs:

master freq: controls all four eq's frequencies
bandwidth: 0 to 5volts for 0,6 to 0,02 (frequency at -3db point/ peak frequency)
level: 0 to 5volts
maximal input/output: 20volts p-p
overload indicator: at 3db below clip level
current consumption: 110ma
dimensions 128.4mm (h), 121.7mm (b), 3 he, 24 te
