Electronic power-down

The audio amplifier is connected to "terminal 30" and GND for voltage supply. The audio amplifier works in an operating voltage range of 9 to 16 volts (alternatively from 7.5 to 16 volts) at the control input.

If the voltage at the control input is lower than 9 volts (alternatively lower than 7.5 volts), the audio amplifier is automatically switched off. This ensures that the audio amplifier does not remain switched on, for example in a parked vehicle.
