Triple VC Resonance Filter

A-127

1. Introduction

Module A-127 is a Voltage-Controlled Triple Reso-

nance Filter

), consisting of three separate

band pass

filters with one common input.

For each of the filters, the

filter frequency

and

Reso-

nance can be manually controlled, and in addition

the filter frequency can be voltage controlled.

Each

filter has its own audio output. There is also a Mix

output which takes your chosen amounts of each of

the three filter outputs and the original signal - set by

the Audio Level controls - and outputs them from one

socket.

Each of the filters also has an internal LFO (a triangle

waveform) for modulating the filter, and there are

controls for LFO frequency and amplitude. Instead of

the LFO, an external control voltage can be used,

whose amplitude can be manually controlled.

There is an alternative scenario:- each of the

three filters can also be configured as a

12dB low-pass filter

with resonance con-

trol. To do this, a jumper has to be re-

positioned on each of the three circuit boards

(see chapter 7, Appendix).
