Hi folks,

Hoping for advice on a strange issue.  I have a Beolab 7-2 speaker used as a centre channel in a 5.1 set-up, alongside BL8000 fronts, BL6000 rears and a BL19.

These are all being driven from the preouts of an Anthem MRX520. The 7-2 is connected via an RCA-to-powerlink cable which also incorporates a 5v trigger which is connected to a USB socket on the TV

A couple of months back I first noticed a distortion on loud voices when playing one particular film.  I thought it was a one off and as it was a rip, I thought maybe I’d done something wrong. Since then I’ve noticed it on a few other things from various sources: other rips and also some streaming services. However it definitely doesn’t happen on everything.

I did wonder whether it was an input sensitivity mismatch and tried lowering the output level of the anthem, but then of course I was turning up the volume commensurately more, so I guess it’s all the same in the end and indeed I don’t think that made a difference.

It’s a weird one because it never happened before a couple of months ago, and it doesn’t occur on everything.

Any ideas? Does anyone have the input sensitivity spec for the 7-2, then I can check if that might be the issue?

I could pick up another 7-2 for a relatively modest cost, but want to be sure that this one is actually faulty before doing that, and at the moment, that seems unclear.

Thanks for your help.

Dan
