The digital Top HiFi amplifier (AMPT) and the High End HiFi amplifier (AMPT) convert the digital audio signals transmitted from the headunit to the MOST bus into analogue audio signals. The Top HiFi amplifier and/or High End hi-fi amplifier (AMPT) also receive the analogue signals from the Active Sound Design (ASD). The combined and amplified audio signals are transmitted to the relevant speakers.
