Audison Bit DMI – Digital MOST Interface

The Audison bit DMI is a digital interface for MOST systems, providing the ability to connect the Audison bit processors and the Audison amplifiers, equipped with digital input, to OEM multimedia systems in cars featuring the MOST technology based on optical fibre. Thanks to the digital connection, the signal can be transmitted without loss of quality, keeping the audio controls built in the OEM head unit – such as volume, balance and tone controls- as well as the hands-free kit, navigation system and parking sensors alerts unaltered.
