Brief description of components: Amplifiers

The amplifier has 4 input channels and 7 outputs. The amplifier has a separate power supply. The amplifier is switched on by the RAD_ON signal from the ASK (> 8 V = ON/< 6 V = OFF).

On request from the ASK, the amplifier performs speed-dependent volume adjustment. The low frequency range in particular is boosted at high driving speeds.
