Hi everyone,

I have multiple DDRC24 units working on a 5.1 setup:

Unit A = Front LR
Unit B = Front C and LFE
Unit C = Rear LR

My Front LCR are very well placed, there's nearly no need for delay to align them, but my Rear LR are closer to my listening position, so they require some 5ms of delay to compensate. Everything is aligned manually with the help of REW.

After some initial tests I managed to get the Front LCR tuned very tight, but I wanted to start fresh on the Front LCR to include the Rear LR. That's when a weird problem showed up. For some reason, Unit A (Front LR) started to present a 10ms delay on both channels, and no matter what I do, I can't get rid of it. Doesn't matter if there's any Dirac filter in place or not. I've tried flashing other firmwares, rolling back to MiniDSP 2x4HD and then back to DDRC24... no luck.

I can't recall precisely what I did right before the problem started, but I definitely didn't do anything unusual other than just loading a fresh Config file or something I had already done several times with no issues.

I understand I could just swap Unit A with Unit C (since the Rear LR always have 5ms of delay), but I'm trying to avoid adding any unnecessary delay to the Front LR because I use them for recording as well, and the DDRC already has a latency of 13ms, a bit high for this task.

Any help or suggestions?
