Low Level Signal Output Terminal
Support maximum 8 channels
Working Status Indicator
POWER: Working status indicator. When the processor finishes self-checking and go
into proper working status, Blue LED will illuminate.
ALARM: Protection status indicator. When this indicator flases, it indicates that the
processor is in abnormal working state and there’ll be no output signal.
Power Supply Terminal
B+: Used to connect the positive terminal 12V car battery. In order to ensure
adecuate power supply for the processor, special cable should be used to connect
directly, to the positive pole of the battery, and the fuse should be connected in series
within 20 centimeters from the positive pole of the battery..
GND: Used to connect amplifier grounding cable. The power supply grounding cable
need to be firmly connected to the frame of the vehicle or other places with good
conductivity. Please use the cable with same specifications as the power supply cable
and connect to frame of the vehicle near the installation position of the processor.
Auto Turn ON/OFF Control Model Options
For auto turn on/off mode, it offers three options: DC OFFSET/REM/AUDIO.
REM: When switched to REM, the remote control output terminal of the OEM source
unit is connected to the REM IN terminal of the DSP / amplifier, which is the preferred
starting method.
DC Offset: If the OEM source unit has no REM signal output, you can choose DC
OFFSET mode. DC OFFSET can turn on/off amplifier by detecting the 6V DC Offset
from the OEM source unit terminal.
Audio: This mode controls the power switch by detecting audio signals from the
source unit. When using this mode, please pay attention to the volume settings of the
source unit.
