DA1 MOST25 Digital Preamp

Description

The DA1 has been specifically designed for aftermarket car audio systems to interface seamlessly into MOST25 vehicle bus networks for unprecedented control and audio reproduction.

Blackfin DSP

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.

Burr-Brown

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

Seamless Integration

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.

Note

• This product is designed to integrate factory MOST25 systems with aftermarket car audio
• This product should be used when running an external DSP processor
• This product has the graphic equalizer disabled for BMW vehicles, equating to more volume. This is in contrast to the DA-G2 Standard, which has less volume, and has it’s graphic equalizer enabled.
• When a DA-G2 Pro 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.
