perfectly if either the audio source does not incorporate any volume adjustment or the source always delivers a high signal
level. In that case the audio processing inside the BRAX DSP is done without reducing the audio resolution at any time. For
adjusting the playback volume either the cable remote URC.3 or the display remote DIRECTOR can be chosen.
The speciality lies in the fact that the volume information from the remote will be encoded inside the BRAX DSP and em-
bedded into the digital audio data stream of the SPDIF outputs and thus transferred to the MX4 PRO.
The MX4 PRO itself is able to extract and decode the volume information from the digital data stream, using this to adjust
the lossless analog volume controllers (PGA’s) after the DA converters. This simply means that the volume control takes
place in the signal path where it does not have any negative impact on sound quality, actually just before the output stages
that drive the loudspeakers.
This type of volume control is truly an uniqueness in the car audio segment and proofs once again that Audiotec Fischer
didn’t spare any effort to redefine the pinnacle of sound quality once again.
