What I'm testing...
Not configured completely yet... hoping to get it working tomorrow...
Mobridge DA2 MOST to analog/MOST to Toslink gateway: - MOST input - 8 RCA outputs (2 pair fading, 2 pair non-fading) - Toslink S/PDIF digital output - internal DSP EQ controlled by 7-band EQ UI in BMW head unit - 24-bit Burr-Brown DACs - 4V RMS analog outputs - USB programming (no more SD card!) |

You can configure this thing to allow the EQ in the BMW UI to adjust the EQ in this unit??? I suppose that would make sense if the signal processing is done in the factory unit as well, but that is awesome!
Can you assign different frequencies and Q's to the eq bands? I would assume you woulnd't be able to change what it says on the screen though... This thing looks seriously promising for a badass system. |

This weekend I will test exactly what that means, with the RTA. It isn't customizable at all... But it's better than bass and treble controls. The head unit recoded today, not sure how it happened or what I did "right". But I have EQ on the iDrive now and my analog outputs are dead, and I have output from the DA2 now. I currently have the Toslink out feeding a Helix DSP, feeding an Arc amp. No noise, no hiss, clear as day. |

In this configuration, is it basically acting as a MOST to toslink converter? Since you have a DSP downstream, would you be EQing the signal 2x? Would the OEM volume control still work when using the toslink output?

Now as far as why, I'm not sure. The original Sony/Philips specification for S/PDIF doesn't define volume control specifically. There are some "words" reserved for some possible volume state data, and perhaps those have been defined in a later version of the specification which I haven't read. It's also possible that they are doing some transform where they are changing the amplitude of the signal in the digital domain based on some algorithm they have created, which looks at the volume knob state of the HU. If they do that, they are essentially compressing the dynamic range of the digital signal, but that's not a horrible thing, since in a car - especially a moving car - the dynamic range of a CD is useless, and Ken Pohlmann - an early advocate of digital audio - long advocated a "compression" button for CD players for cars for this reason. But it seems great so far. |

I have not yet received a firmware version which would allow the device's RCA outs to be used with any degree of fidelity. I do not knows for certain if the issue is firmware or hardware. Wish I had different news, but I will keep you posted. I would like to use these in that manner too...
