The ZEN-AUDIO ZEN-25 processor seamlessly converts 2004-2019 BMW M.O.S.T. 25 factory amplified infotainment systems to 12-channel analog RCA and TOSLink output. Adding aftermarket amplifiers to the factory amplified BMW M.O.S.T. system has never been so simple. This module integrates directly with the M.O.S.T. bus to retain volume control, full fade (analog only), balance, treble, bass control, factory 7-band EQ & phone calls with no external speaker (true OEM integration).

The interface comes standard with a user interface that allows 2 different time alignments selectable through the factory Logic 7 button, full independent control of phone and gong volumes, the ability to reassign audio, warning chimes or phone calls to any channel, and simultaneous use of the digital TOSlink and analog outputs. ZEN-25 includes a single stereo TOSlink output and 12 analog channel outputs, providing 17 volt peak-to-peak with a signal to noise ratio of 114dB.
