Hi folks,
I've just joined but have a bit of a query, I have a ML 5.1 setup but have noticed that there is a loud hum coming from one of the Quest speakers' panels.
I am using Mark Levinson 331 amps (bridged) to the front speakers. They are connected via XLRs to a Bryston SP7.1 pre-amp.
I've tried swapping the XLRs to each speaker/amp at the preamp but have found that the problem is definitely with the speaker panel itself - as connecting the other amp to it still makes it hum! The same amp does not hum when connected to the other speaker.
I even tried to unplug the speaker overnight and disconnect it from the power amp but this had no effect.
I did notice that if I took the XLR for the power amp to this speaker off at the preamp side that the hum was MUCH louder. It went quieter as soon as I reconnected the XLR to the preamp again.
I have had the same setup for many months but have never had anything like this before.
Any advice? Is it likely to be a problem with a component in the X over ?
Any help would be much appreciated!
