Av2 -No signal in center and back

Posted by: Eplemac on 03 December 2008

Hey! Received my AV2 about a month or two a ago, and I was told by the reseller that it was completely new, so i guess it has the latest firmware...

The av2 is connected to two nap 250 cb (one to the center and one to the front channel) and two nap 90/3 for the surround channels.

The sources are a sony bdp-s550 and a Oppo DV-983hd.

The problem is that there is only sound coming out the front speakers, and not the surround/rear/center channels. The DTS led is lighted in the display as well...

Ive dobbelchecked all the connection, cables, and the different poweramps -they all work on the front channel... So Ive narrowed it down to being the Av2...

Anyone have Any idea? Should I just send it back to Naim? -Dont like the idea of spending the Christmasholiday without the naim systemFrown

I presume that you have spent quite some time following the Users Manual and are connected to your sources via a suitable digital cable and have set up these inputs to receive digital signals?

Yes! It worked perfect until yesterday... Came home, and nothing worked. Had it powered off for app. 24 hours, and when I turned it back on, only the front speakers were working...

2) check setup settings have not reset themselves back to defaults, i.e. are C/Surr on in the setup menu??
