+12V
The terminal marked +12V should be connected to a permanent (i.e. not ignition switched) positive 12 Volt supply from
the vehicle battery.
GND
The terminal marked GND (Ground) should be connected to a cable which is terminated to the vehicle chassis.
Ensure that the point where this cable attaches to the vehicle chassis provides good electrical contact. It may be ne-
cessary to rub away paintwork to expose the metal at this point. In this case, after making a firm screw connection of
the ground cable to the chassis, paint over the terminal point to protect the metal from corrosion.
To avoid noise problems, ensure that this point on the vehicle chassis measures as a true ground reference. You will
need a multimeter to check that there is no (or very minimal) resistance (in ohms) between the battery negative post
and the point you have chosen on the chassis.
If drilling a new ground point, check that there is nothing behind the panel you are about to drill, such as the fuel tank!
Where a ground point already exists (for an existing power amplifier, for example) it is generally best practice to ground
the ADP amplifier and any other system components to this same point on the vehicle chassis (a practice known as
Star Grounding). This helps ensure that the ground reference is the same for all components, thus avoiding the chance
of automotive noise.
REM
The terminal marked REM (remote) accepts a +12V switched input from the source unit (Cassette or CD player). When
the source unit is switched on, a pulse is sent down this line. The amplifier senses this pulse and switches itself on.

Installation & Setup Instructions
5
The source unit should be equipped with a suitable Remote Switch cable - check the instruction book supplied with your
Tape or CD player.
If the Remote output from the source unit is already being used to switch on another unit that is close to your ADP
amplifier, it is usually possible to 'daisy-chain' a cable from the Remote terminal on that unit to the REM terminal of the
ADP amplifier. This avoids the need to run a separate cable from the source unit.
You will find a Power Input terminal block at the far end of the side panel. There are three connections to be made:
