The DA1 has been specifically designed for MOST25 systems to interface seamlessly into the vehicle bus network for unprecedented control and audio reproduction.
The heart of the device is a 533MHz Blackfin Digital Signal Processor (DSP). The DA-G2.Standard MOST25 allows for channel summing, channel mapping and mono channel volume controls only. It does not contain any advanced DSP processing beyond what the vehicle controls provide such as bass, treble, balance, and fade etc.
The pre-amp stage is driven by a Burr Brown DAC converter, providing an audiophile quality without compromise.
The DA1 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 fully 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.
The DA1 also eliminates the need for high to low voltage converters and/or summing devices, as well as the need to cut into the vehicle’s wiring to access the audio signal.
mObridge DSP User Interface
The DA1 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.
- This product should be used when running an external processor, and not the DA2 as it does not contain a digital output.
- This product has the graphic equalizer disabled for BMW vehicles, equating to more volume. This is in contrast to the DA2, which has less volume, and has it’s graphic equalizer enabled.
- When a DA2 is used in conjunction with an external processor via the low level RCA analog connections, which also has a graphic equalizer, the overall volume is too low which has resulted in installers trying to compensate by increasing the amplifier gain which also increases the amplifier noise floor to an unacceptable level.
The mObridge DA1 MOST25 Digital pre-amplifier provides a connection between the in-vehicle MOST25 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 DA1 does not contain advanced DSP controls beyond what the vehicle provides, such as bass, treble, fade, and balance. For a complete DSP solution, with advanced DSP algorithms, the DA-G2.Pro MOST25 can be used. If only basic analog + TOSLINK outputs are required, the DA-G2.Standard MOST25 can be used.
