6. ADSP 8 INSTALLATION PROCEDURE
The ADSP 8 has been designed for easy installation into your vehicle.
Please follow the indications below to ensure good operation and long term
reliability.
1. The ADSP 8 digital sound processor needs to be installed in the
signal path between your signal source and your external amplifier(s).
2. The ADSP 8 digital sound processor must be installed to a
solid surface. Please select a dry clean location in the trunk or passenger
compartment only. Do not install the ADSP 8 to any area that may experience
excessive vibrations. Position the ADSP 8 processor in a location that will allow
for sufficient airflow with taking into mind an ease of service for subsequent
accesses.
Notes:
We suggest to check the suitability of the installation before you
begin. Do not cut any of the car’s structure, take heed to what could be
beyond the panel or carpet where you intend to operate. The manufacturer
will hide wires, computers or other electronic devices in the exact areas you
wish to install your product.
When installing your ADSP 8 to the floor of the vehicle, be sure to
inspect underneath the vehicle to prevent damage to the vehicle’s fuel
delivery system or factory wiring, so as to prevent serious damages or
hazardous conditions to your vehicle.
If you don’t have experience with automotive electrical and
mechanical systems, contact a professional installer. Paying a qualified
installer is almost always cheaper than paying a dealership to repair your
car.

and REM IN2, by other devices (such as : source device vehicle, DVD, etc.) though
the signal input to control the processor.
Note:
The REM IN input can be connected in parallel.
7.1.3. REM OUT
Provided 4 pcs “same time same voltage” output control interface REM OUT1 -
REM OUT4 to control the car amplifier. You can also use only 1 pc and join-up in
parallel of all the external car amplifier, then others as spare.

8.2. Input, Output, Routing Connection Rules
Power amplifier output to the corresponding speakers, we define the six
sound field locations: left-front, right-front, left-rear, right-rear, center and subwoofer.
Specific output signal corresponds to the input of the routing rules defined as
follows: (general rules: the left input signal is sent to the left speaker sound field, the
right input signal is sent to the right speaker sound field, front input signal is sent to
the front speaker sound field, front input signal is sent to the front speaker sound
field, rear input signal is sent to the back speaker sound field.
