Synthesis Technology E440 Discrete OTA VCF, USED
This item is used, has been fully tested and is guaranteed to be working.
Voltage-Controlled Lowpass FilterThe Synthesis Technology E440 is a lowpass voltage-controlled filter with 3 simultaneous outputs. The input is any audio source (can be from line level to synth level) and the output is via the different slopes of the filter: 2pole (-12db/oct), 3pole (-18db/oct) and 4pole (-24db/oct). There are 3 CV inputs to control the cutoff frequency plus a separate CV input for the resonance. The E440 will self-oscillate at high resonance and can be used for a sine VCO (each output is phase shifted 45 degrees from the prior one) with 1v/Oct tracking (trimmable) over a 4-octave range. This response is also temperature-compensated. An external audio mixer module can be used to blend the 3 outputs into “in-between” slopes and by inverting them relative to another, different frequency responses.
