Why do I get buzzing coming out one Speaker when I Change the Input Selector on my Denon Amp? Please Help?
It Doesn't happen when The Tuner is on or the CD it only seems to happen with the Turntable and the Tape Player? I know it's an Old System , but I've tried everything I've took the system apart then reconnected the wiring , even tried different speakers it seems to coming back now and again I have to play about with the wiring and sometimes it goes away?Is buzzing only happening while you are switching sources of is it still there afterwards?
Source selector switch may simply need a squirt of contact cleaner
Amplify. Please explain why this might only effect the source switching in two positions only....It's likely to be a light dimmer or switch mode power supply nearby.
True that OP reports only 2 out of 4 affected sources, but if you had to pick the 2 most susceptible to nearby interference, it must be TT cart and tape head with their high gain amps - maybe TT signal lead acting as aerial - and why moving cable clears buzz??Amplify.

He never said anything was connected to the tape input and one reason I asked him to remove the turntable leads to see if it still happened.True that OP reports only 2 out of 4 affected sources, but if you had to pick the 2 most susceptible to nearby interference, it must be TT cart and tape head with their high gain amps - maybe TT signal lead acting as aerial - and why moving cable clears buzz??
He mentions a tape player above, so I assumed one was connected.He never said anything was connected to the tape input and one reason I asked him to remove the turntable leads to see if it still happened.
Correction, he does mention a tape player. So perhaps it may be feedback depending on the tape source switch position.
I hope so as he hasn't yet responded to my suggestion,He mentions a tape player above, so I assumed one was connected.
Who knows? He'll let us know probably.
Why wouldn't it?Amplify. Please explain why this might only effect the source switching in two positions only....
