OPERATIONS & CONTROLS
NO.
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.
Before connecting the power supply, you must confirm that the power supply meets
the designated power requirements and connect in strict accordance with the
equipment instructions. Otherwise, the equipment may be damaged and may cause
accidents such as fire, electric shock, etc.
Remote Turn-ON Singal In/Out
REM IN: Connect it to the ACC control output Singal. The processor will switch on/off
automatically with vehicle ACC signal on/off.
REM OUT: It provides separate REMOTE signal output to the other amplifiers to
control other amplifiers switch turn on/off. Note: the starting signal of the external
power amplifier must be taken from the REM OUT terminal of this equipment.
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.
