DA-G2.ENTRY MOST150 Coaxial Mercedes Preamp

DA-G2.ENTRY MOST150 Coaxial Mercedes Preamp

The mObridge DA-G2.Entry MOST150 pre-amplifier provides a connection between the in-vehicle MOST150 infotainment system, with any aftermarket DSP/amplifier containing TOSLINK input capability.

It provides a TOSLINK output, and an amplifier turn on/off control. Multi-vehicle compatibility is provided via DIP switches, and a USB connection can be used to connect it to the mObridge DSP user interface for configuration and firmware updates.

The DA-G2.Entry MOST150 also allows adjustment of the mono sinks such as Phone, Navigation, PDC and Voice recognition to compensate for OEM systems that may need adjustment.

Pls note: The DA-G2.Entry also allows the mono sink channels to bypass the time buffering to avoid delays and issues such as echo cancellation but once passed to an external processor this feature is beyond the control of the DA-G2.Entry processing.

The DA-G2.Entry MOST150 does not contain advanced DSP controls beyond what the vehicle provides, such as bass, treble and balance. For a complete DSP solution, with advanced DSP algorithms, the DA-G2.Pro MOST150 coax can be used. If only basic analog + TOSLINK outputs are required, the DA-G2.Standard MOST150 coax can be used.


The DA-G2.Entry MOST150 Coaxial has been specifically designed for MOST150 systems to interface seamlessly into the vehicle bus network for unprecedented control and audio reproduction.

Blackfin DSP

The heart of the device is a 533MHz Blackfin Digital Signal Processor (DSP). The DA-G2.Entry MOST150 Coaxial controls mono channel volume controls only. It does not contain any advanced DSP processing beyond what the vehicle controls provide such as bass, treble, balance etc.


The pre-amp stage is driven by a Burr Brown DAC converter, providing an audiophile quality without compromise.

Seamless Integration

The DA-G2.Entry MOST150 Coaxial interfaces seamlessly with the controls of the vehicle. Volume, balance, bass, and treble remain completely controllable via the existing vehicle controls, and all factory audio such as parking sensors, navigation, voice, and telephone are integrated to behave exactly as per the original system. This means that unlike other integration options, there is no need for mounting of any additional controls inside the vehicle. The vehicle will look and feel stock, with exceptional audio quality.
