DC Offset：If the OEM source unit has no REM signal output, you can choose DC OFFSET
mode.DC OFFSET can turn on/off processor 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.
If the volume of the source unit is too low, the processor may fail to turn on.
7.High Level Signal Input Terminal.
MAESTRO-812DSP-DSD features 8 high level signal inputs to connect amplified signal
cables coming from the main analog source.
8.REM IN & OUT.
REM IN: Connect it to the ACC control output Signal. The product will switch on/off
automatically with vehicle ACC signal on/off.
REM OUT：It provides separate REMOTE signal output to 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.
9.AUX Auxiliary Source Signal Input Terminal.
MAESTRO-812DSP-DSD features an auxiliary stereo signal input to connect an external
source mp3 player or other audio sources.
10.CH9/10/11/12 speaker output.
Connect speaker/subwoofer to these terminals. Be sure to check wire for proper polarity.
Never connect the speaker cables to chassis ground. Each channel output power is
100Wrms @4ohm or 170Wrms @2ohm.
11.Working Status Indicator.
POWER LED：Working status indicator.When the processor finishes self-checking and go
into proper working status, Blue led will illuminate.
PROTECT LED：Protection status indicator. When this indicator flashes, it indicates that
the product is in abnormal working state and there will be no output signal.
12.POWER.
+12V: Used to connect the positive terminal 12V car battery. In order to ensure adequate
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 product.
13.CH5/6/7/8 speaker output.
Connect speaker to these terminals. Be sure to check wire for proper polarity. Never
connect the speaker cables to chassis ground. Each channel output power is 100Wrms
@4ohm.
14.CH1/2/3/4 speaker output.
Connect speaker to these terminals. Be sure to check wire for proper polarity. Never
connect the speaker cables to chassis ground. Each channel output power is 20Wrms
@4ohm.
