122 ANDROMEDA A6 REFERENCE MANUAL
HOW FILTERS WORK
In Chapter 3, we used a number of flowcharts to illustrate how audio, modulation
and control signals flow though a generic synthesizer. Since the A6 is more advanced
than our generic example, let’s expand on this model with specific A6 components:
1. The A6’s audio sources, before being routed to the filters, have their levels set
in the
PRE FILTER MIX section.
2. The output of the PRE FILTER MIX is routed first to FILTER 1 where the initial
frequency is set by the
FREQ knob.
