1.
RCA INPUT JACKS
- accepts line-
level outputs from head units or
signal sources at voltages from 200
mV to 8 volts.
2.
RCA INVERT IN JACK
- use this jack
to accept signal from another
600d/1100d when operating in
synced slave mode. This jack also
supplies an in-phase output when
the unit is set to “Master”.
3.
RCA INVERT OUT JACK
- use this
jack to send an inverted phase
signal to another 600d/1100d
operating in synced slave mode.
4.
MASTER/SLAVE INVERT SWITCH
-
selects operating mode for synced
operation. For normal operation set
to master/0.
5.
GAIN ADJUSTMENT
- controls the
gain (input sensitivity) of the
amplifier.
6.
SUBSONIC FILTER
- Switchable vari-
able subsonic filter prevents
damage to subwoofers in vented
and free-air applications.
7.
BASS EQ
- This switch activates an
8 dB bass boost circuit. Use as
necessary for low frequency
enhancement.
8.
CROSSOVER FREQUENCY
- controls
the cutoff frequency of the built-in
low-pass crossover.
9.
OUTPUT PHASE INVERT SWITCH
-
controls the output phase of the
amplifier. The output signal inverts
with the switch set to 180.
10.
REMOTE SUB LEVEL
- controls gains
of the amplifier.
