Pre-Amplifier

mObridge DA-G2.Pro MOST25

The mObridge DA-G2.Pro MOST25 pre-amplifier provides a connection between the in-vehicle MOST25 system with any aftermarket analog/digital DSP/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 MOST25 is a complete DSP solution, with advanced DSP algorithms. If only basic analog + TOSLINK outputs are required, the DA-G2.Standard MOST25 can be used. Where only basic TOSLINK outputs are required, the DA1 Digital Pre-Amp MOST25 can be used.

  • description

    The DA-G2.Pro MOST25 has been specifically designed for MOST25 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 MOST25 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.

    Burr-Brown

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

    Seamless Integration

    The DA-G2.Pro MOST25 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.

    mObridge DSP User Interface

    The DA-G2.Pro MOST25 utilizes the mObridge DSP desktop application for Windows/macOS to harness the full potential of the DSP. The application is also able to provide automatic online firmware updates.
