4.4
DC
POWER
The C-DSP 8x12 incorporates an isolated DC-DC power convertor and is designed for direct connection to the
vehicle's power supply (nominally 12 V DC). Power is connected via a four-way terminal block. There are two
modes of operation, described below.
4.4.1
Powered on power (position 1)
To power on the C-DSP 8x12 whenever 12 V DC is applied to the
DC IN
terminals, set the
REMOTE MODE
switch
to position 1. Typically, power is provided from the main vehicle supply (always on).
4.4.2
Remote trigger (position 2)
To reduce battery drain, the remote trigger option should be used. To enable remote trigger, set the
REMOTE
MODE
switch to position 2. In this case, the C-DSP 8x12 is powered on when the voltage on the
REMOTE IN
terminal exceeds 4 V DC. Typically,
REMOTE IN
is connected to the remote trigger output from the head unit.
In this mode, the
REMOTE OUT
terminal should be used to turn on the power amplifier(s). There is a time delay
between
REMOTE IN
going positive and
REMOTE OUT
going positive. This can be configured in the plugin
–
see
page 40.
Position 3 of the
REMOTE MODE
switch is reserved for future use. Do not set the switch to position 3.
