Analogue/digital converter

WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

The audio signals between headunit and amplifier are transmitted directly via 8 lines. These lines connect the speaker outputs of the headunit with the signal inputs of the amplifier. The analogue signals are digitized by the analogue/digital converter. This enables further processing without quality losses.
