Before installing the P.I.P. mod-
ule, it should first be configured.
3.1 P.I.P. Configuration
1. Set the corner frequency (–3 dB
frequency) for each subsonic
filter with DIP switches S1 and
S2 (see Figure 3.2). Notice that
the first six switch segments
control the corner frequency.

Figure 3.2). Notice that the
last three DIP switch seg-
ments control attack and re-
lease times. The actual attack
time depends on the release
time. Figure 3.3 provides ap-
proximate times for each set-
ting.
3. Adjust each channel’s com-
pressor threshold using the
compressor threshold pots
(see Figure 2.1, “C”). Each
