The mObridge DA-G2.Entry MOST150 pre-amplifier provides a connection between the in-vehicle MOST150 infotainment 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 DA-G2.Entry 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. Pls note: The DA-G2.Entry also allows the mono sink channels to bypass the time buffering to avoid delays and issues such as echo cancellation but once passed to an external processor this feature is beyond the control of the DA-G2.Entry processing. The DA-G2.Entry MOST150 does not contain advanced DSP controls beyond what the vehicle provides, such as bass, treble and balance. For a complete DSP solution, with advanced DSP algorithms, the DA-G2.Pro MOST150 coax can be used. If only basic analog + TOSLINK outputs are required, the DA-G2.Standard MOST150 coax can be used.
