Hi Jeroen,

Thanks for the update, so if I have this right:

The 861v4 is connected to the 7200 via Coax.
The 818v1 is connected to the 7200 via SpeakerLink.

So effectively you have two semi-independent systems sharing a pair of DSP7200s.

For this setup the 7200 that the 818 is connected to must be the MASTER DSP and its Aux (SLS) input must be configured to use the SpeakerLink input (not the coax).

Unless recent firmware has changed this behaviour. The SLAVE DSP always use just one input (either Coax or SpeakerLink dependent on config).

So this means that the SLAVE 7200 should just be connected to the MASTER DSP (not the 818) and I'd suggest doing that via SpeakerLink.

----------

Once this is working and note I suspect this will not work but it might now know with later firmware so it's worth a quick experiment to find out.

You could try to configure the SLAVE DSP7200 to use coax input (from MASTER DSP) for all inputs except AUX (SLS) which should be configured SpeakerLink and connected it back to the 818.

Regards,
Carl
