Longtime lurker, first time poster. I've just acquired a second hand BeoCenter 2500 with Beolab 2500 speakers. However, the BeoCenter 2500 does not output any audio when attached to either the BeoLab 2500's or a pair of BeoLab 4000's.
The BL4000's are known to work perfectly - they were unplugged directly from a BM4500 just to test.
The BL2500's attached to the BC2500 never come off standby - red lights stay on.
Is there some auxiliary master link output mode that the BC2500 might be in? How can I debug this problem some more? Tomorrow I'll check the BL2500's are functioning by plugging them into the BM4500, but I'm pretty sure they're functioning fine already.
