DA2 Analog Pre-Amp MOST

The mObridge Analog Pre-amplifier provides a connection between the MOST system in the vehicle with any aftermarket analog amplifier.

It provides 8 channels of RCA analog outputs and an amplifier turn on/off control.


This product has been superseded by DA-G2.Standard MOST25.

Full retention of the factory controls is supported – control Volume, Balance, Fader, and Equalizer (where applicable). There is no need for an external mounted controller or volume knob.


  • From software revisions 1.7.0 onwards the DA2 has gained channel mapping available through the mObridge DSP graphical interface. The default mapping in its nonvolatile memory may not match your current output channels. Please refer to the release notes for the channel mapping description and details.
