1. Introduction
Module A-128 (Fixed Filter Bank) is a filter bank,
made up of
15 parallel band pass filters
, all with
fixed middle frequencies and bandwidth:
50 Hz 350 Hz 2.2 kHz
75 Hz 500 Hz 3.6 kHz
110 Hz 750 Hz 5.2 kHz
150 Hz 1.1 kHz 7.5 kHz
220 Hz 1.6 kHz 11.0 kHz.
Each band pass filter has its own amplitude control
knob, with which that frequency band can be attenua-
ted. The bandwidth of each of the filters is approxi-
mately half an octave.
The signal at the output of the A-128 contains a mix of
all the filters, depending on the position of each one’s
amplitude control knob.
The filter bank’s main job is to emphasise individual
sections of the whole audio frequency range. It’s like
a passive 15-band EQ.
