- Page 5 Installation & Setup Instructions Mounting the Unit Your ADP Series Power Amplifier has two fixing 'ears' at each side, allowing it to be firmly screwed to a suitable surface. It may be mounted vertically or horizontally, but avoid mounting the unit upside down (suspended from a shelf, for example) since this may affect efficient heat dissipation.
- Page 6 You will find a Power Input terminal block at the far end of the side panel. There are three connections to be made: +12V The terminal marked +12V should be connected to a permanent (i.e. not ignition switched) positive 12 Volt supply from the vehicle battery.
- Page 7 Installation & Setup Instructions Use the correct size Allen Key to tighten the terminal screws. Before reconnecting power to the circuit, double check all connections are correct and ensure there are no stray strands of wire which could touch the chassis of the ADP amplifier or any of the other terminals.
- Page 8 (single channel) mode, or in tri-mode. However, it is possi- ble to operate your stereo amplifier in bridged mono mode as long as the overall speaker load is no less than 8 ohms.
- Page 9 Brief Technical Overview Although commonly referred to as a "digital" amplifier, Class-D is more accurately described as a Pulse Width Modulated (PWM) amplifier. A PWM amplifier converts the music (which is a complex arrangement of sine waves) into a series of pulses.

Troubleshooting Power LED not lit: Is the Remote switch cable from the source unit (Cassette or CD Player) attached to the REM terminal of the ADP amplifier, and is the source unit switched on? Are the +12V and GND (Ground) terminals connected correctly? Is the Ground cable properly attached to the chassis of the vehicle or to an existing ground point that is known to be OK? Check the fuse and replace if blown (use only a fuse of the correct rating).
