AUDIO AMPLIFIER CONSTRUCTION

BHE092066910T01

## Main Amplifier

• Located in the rear package tray.

• A digital amplifier has been adopted.

• Converts music signals (analog voltage waves) output from an audio unit, into digital pulse signals, and then amplifies and outputs them.

## Front Door Speaker Amplifier

• Located in the front door trim.

• A digital amplifier (switching amplifier) has been adopted.

• On/off digital signals are amplified and output, allowing power conservation and lower heat generation. Due to this, a radiating plate (heat sink) is not required, and downsizing of the amplifier has been achieved.
