Connect the remote terminal of the crossover to a swit12V.
This connection allows the crossover to be turned on and off with the power
control of the head unit. If the head unit has a
REMOTE OUTPUT WIRE
(+ 12V),
connect it to the
PLXR3B
terminal marked REM. Now when the head unit is
turned on, the crossover will automatically turn on. If the head unit does not
provide a remote output, it is necessary to connect the crossover to a sw
12V power supply (when the car is on or in use).
SIGNAL CONNECTIONS
Before making your signal connections, you will need to decide how you wish to
configure your system. The
PLXR3B
is extremely flexible allowing for many
different configurations. All signal connections should be made using higher-
grade RCA patch cables and these cables should be run away from electrical
wiring to avoid inducted noise. The
PLXR3B
allows for three different types of
input connections that control all three outputs of the crossover.
1. USING ONE PAIR OF PRIMARY INPUTS
When only one pair of input is available, input the signal into the “
FRONT
"
input section and set the
SUBWOOFER INPUT
switch to “
MIXED
" and
“
Y-CONNECT INPUT
” switch to “
ON
" position. This will allow the signals to be
fed internally to the
SUBWOOFER
and
REAR
sections to give proper outputs.
