1. RCA INPUT JACKS - accepts line-
level outputs from head units or
signal sources at voltages from
200mV to 8 volts.
2. GAIN ADJUSTMENT - controls the
gain (input sensitivity) of the
amplifier. Each control sets the gain
for that half of the amplifier.
3. CROSSOVER SELECTION SWITCH -
controls the type of filter for each
of two on-board active crossovers.
Set crossover switches for proper
filter type depending on system
configuration.
4. REMOTE SUB LEVEL - controls the
subwoofer output level
5. SUBWOOFER LOW-PASS
CROSSOVER - use the gain and
crossover frequency controls to
adjust the subwoofer output.
6. BASS EQ - This switch activates an
8dB bass boost circuit. Use as
necessary for low frequency
enhancement.
7. CROSSOVER FREQUENCY - controls
the frequency range of the ampli-
fier. Each half of the amplifier can
be set independently for optimum
performance.
8. LED INDICATOR - the green Power
LED lights to indicate normal opera-
tion. The green LED will shut off to
indicate amp shutdown due to
thermal, short circuit, DC offset, or
over-current conditions detected by
on-board protection circuits.
