SS75.2 / SS125.2 2-CHANNEL AMPLIFIERS
The
X-OVER
slide switch selects the internal crossover functions:
-The input signal is routed directly to the
LINE OUT
RCA jacks, regardless of the
X-OVER
setting simplifying daisy chaining of amplifiers.
-HPF:
Selects the built in
HIGH PASS
filter, variable from 60 Hz to 1.2kHz.
-FULL:
Bypasses all crossovers for full frequency range operation.
-LPF:
Selects the built in
LOW PASS
, variable from 30 Hz to 250Hz.
MODE
: The mode switch allows you to choose Stereo for full range 2 channel operation or
MONO for bridging operation
HIGH INPUT
: If your radio/CD player does not have unbalanced (RCA) outputs, you can
use the HIGH level (wire) inputs.
LINE INPUT
: The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.
LINE OUTPUT
: The line output passes through signal from the line inputs which allows
you to daisy chain multiple amplifiers from one signal.

The 4 channel amps have the same features as the 2 channel models accept that there are
2 sets of controls.
1 set for channels 1 & 2 and 1 set for channels 3 & 4.
In addition, the 4 channel models have a
