The mObridge DA-G2.Pro MOST150 pre-amplifier & DSP combo provides a connection between the in-vehicle MOST150 infotainment system with any aftermarket analog/digital amplifier.

It provides 10 channels of RCA analog outputs, 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.Pro 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. The DA-G2.Pro also allows the mono sink channels to bypass the time buffering to avoid delays and issues such as echo cancellation and delayed reverse park beeps. The DA-G2.Pro is the most advanced OEM DSP available for these vehicles.

The DA-G2.Pro MOST150 is a complete DSP solution, with advanced DSP algorithms. If only basic analog + TOSLINK outputs are required, the DA-G2.Standard MOST150 coax can be used. Where only basic TOSLINK outputs are required, the DA-G2.Entry MOST150 coax can be used.



The DA-G2.Pro MOST150 Coaxial has been specifically designed for MOST150 Coax 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). With it, the DA-G2.Pro MOST150 Coax is capable of concurrently running advanced DSP algorithms on up to 12 channels. It provides full access to channel mapping, channel summing, parametric crossovers, a 1024 point graphic equalizer, channel high/low/band-pass filters, phase inversion, time alignment, master/channel gain control, center channel upmixing algorithms, in-vehicle preset control, and many other features.


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

Seamless Integration

The DA-G2.Pro MOST150 Coax interfaces seamlessly with the controls of the vehicle. Volume, fade, 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.
