You can ask in the MoOde Audio forum, Tim or the rest are very helpful.

No harm trying. Next, I will try to see if I can control the MPD.

@Blitz, thanks to Tonno, he has a better approach writing directly to the serial interface and controlling the DAM1941 volume. He has shared it on MoOde Audio website. The MPD software mixer is not used this way.

I have tested it and it works like a treat.

Balanced output by itself add 6 dB signal but only 3 dB noise....

Hi — I’m trying to design an SPDIF input for a dam1121. Understanding that Soekris no longer recommends the max3280, can someone with eyes on a dam19x1 confirm the part number for the RS-422 receiver? It looks like it might be a DS26LV32A, but the pictures in the manual aren’t quite clear enough to confirm.

Thanks!

Thanks for confirming. Proper implementation includes Pin 4 (EN) to ground and Pin 12 (EN*) to Vcc?

Check table in datasheet again, any other combination will work. I have both to GND.
