High End audio amplifier

High End audio amplifiers (AMPT) are audio amplifiers with active frequency diplexers. Active frequency diplexers achieve better acoustic results than passive frequency diplexers. The speakers that are suitable for the frequency are selectively activated. The active frequency diplexers transfer from the audio amplifier only the frequency range that can be optimally played back by the relevant connected speaker.

In F13, the active 16-channel High End audio amplifier (AMPT) supplies the following 16 speakers with a maximum power output of 1300 watts:

7 tweeter, 12.5 watts
7 mid-range speakers, 75 watts
2 bass speaker, 250 watts

The High End audio amplifier (AMPT) is a control unit in the MOST network with the following functions:

Audio amplifier for high and mid-range speaker
Audio amplifier for bass speaker

The class-D audio output stages of the High End audio amplifier (AMPT) have a significantly higher efficiency and therefore result in reduced power loss compared with traditional audio output stages.
