I have the following setup:
an oldish Arcam 6 amp connected to some Fostex speakers and also to a Wharfedale SW150 sub.
The Arcam does not have line level or sub outputs so I have connected the sub to the arcam using the subs high level inputs from 'speaker b' on the Arcam amp. This suits me well because when I do not want sub output then all I do is switch 'speaker b' off on the front of the amp.
The problem I am having is that if I switch speaker b off then the sub starts to hum. Since I only really switch the sub off for late night low level listening the hum is intrusive...
I could switch the sub off with its power switch but the power switch is at the back of the sub under everything so accessibility is a pain...
Do I have any other options?
