features expand the capabili­ties of your amplifier and en­able you to customize it for your

input of your amplifier. Three
conditions can cause a com­pressor to activate: (1) if the
compressor receives an “er­ror” signal from the amplifier’s
input/output comparator (
circuitry, (2) if the input signal
exceeds its adjustable thresh­old, or (3) if an excessively large

The compressor circuits acti­vate ahead of all preamp cir­cuitry resulting in low distor­tion.

Each channel’s compressor
can operate independently or
both channels can be tied to­gether causing the compres­sors to track each other.

Balanced XLR connectors are
provided for quick connection.

B. DIP Switches (S1, S2)

A nine-segment DIP switch is
provided for each channel.
Segments 1–6 select the sub­sonic corner frequency and
segments 7–9 configure the
compressor. S1 controls chan­nel 1; S2 controls channel 2.

C. Compressor Threshold

Each channel’s compressor
threshold can be adjusted with
these controls. They set the
