I'm using DSP3200 speakers with it, and I presumed, with an AC12/Reviver I would be able to hook in an SW1600 sub.

But it won't play ball. Not daisy changed from a DSP3200 out or direct from the AC200, master or slave out.

The AC200 does have a sub setting but that is just telling the sub and speakers to play full range, crossover at 80hz and crossover at 100hz I think it is.
But that was added in a later firmware update and is designed more for the DSW sub.

I wonder if an earlier firmware might resolve the issue?

Can the firmware be rolled back on these?

I was trying to find out if the comms address has changed? When we set speaker for 500, G, SLS etc. is that changing comms addresses?
Maybe the SW1600 is set at 500 comms and no way to change it?

No Darling, I've had it months!
