Loudspeaker hum/buzz conundrum
Posted by: webrat11 on 16 September 2006
Can anyone suggest a reason as to why I have a hum/buzz in my rear speakers please.
I have upgraded my Olive amps to the latest models. I now have DVD5, AV2, NAP250.2, NAP200 and NAPV145. Wilson Benesch Discovery front, Arcs at the rear.
When I attach the Arcs to the 200 I get a buzz – the equivalent sound level typical of an earth hum. However, when I attach the Discos to the 200 there is no hum. When I attach the arcs to the 250 there is no hum.
I don’t think I have any earth hum – when I switch off the AV2 through which, I understand, every is earthed then I do get earth hum through the centre and rear Arcs (but oddly not the front Discos)
I am a bit confused! Any suggestions or advice will be gratefully received,
Regards Ian,
