+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.
4 4 Fuse 5 5 Input Gain Control Use this control to match the pre-amp output level of your car audio source unit (tape or CD player) to the input stage of the ADP amplifier . The amplifier's input gain is variable from 400mV (MAX Gain) to over 15V (MIN Gain).
See how far you can take the volume control before the signal begins to clip (you may need to reduce the amp gain if it gets too loud). If you see it clip on the scope, back off the volume control a little. Now increase the gain on the amp until you find the highest level before distortion or visible clipping.
8 LTO LTO TM Although commonly referred to as a "digital" amplifier, C lass-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.
