I created a support ticket for this yesterday but wondered if anyone here might want to chime in on the issues...thanks!!

I have a couple of issues with my 990/7700 combo.

I believe it is specifically something with the amp.

I am using balanced inputs from the 990.

1) There is nothing coming from the left channel.

2) Whenever I put anything into the center channel on the amp I get a huge amount of what I can only really describe as "electrical" noise from the speakers.

I swapped out different cables and switched inputs from the 990, but everything seems to come back the the amp.

It also seems to be isolated to those two inputs because I am currently running everything without issue using the SBL and SBR in place of the C and L channels.

(I currently do not have 7 speakers only 5).

Any thoughts?
