EXP.FILTER
0 ~ 0.6
Expander Filter. connect to an external capacitor to filter the full
wave rectifier's output. This capacitor affects attack & delay times, as
well as low frequency accuracy.

EXP.OUTPUT
1.5
Output of the expander amplifier
Expander input. Nominally signal range is 3.16mVrms to
316mVrms. Must be capacitor coupled to the signal source
An internal reference voltage. This is an AC ground, and must be
well filtered to obtain high power supply rejection and low crosstalk.

Input to the compressor Variable gain stage and rectifier.
Normally, this is connected to the compressor's output through
filtered DC feedback path.
Compressor input, Normally. Signal range is 100uVrms to 1.0Vrms.
Must be capacitor coupled to the signal source
