Source selector problem, for eg if the selector is on cd and i plug a cd player in the tuner input, i can hear the sound. no matter what source the selector button is on.
Hi Seamus377
You have a faulty input selector chip by the sound of it. First, power the amp off at the wall for 30 mins, then fire it up again to see if that resets the problem.
Hopefully that fixed the problem, if not, you may need to get a tech to look at it. The input selector chips are quite sensitive and susceptible to failure, producing the symptoms you speak of. They can be damaged also and fail at any point if subjected to a voltage spike. Here is why they fail
When outboard devices such as
are plugged into your amp, the RCA connectors connect the center "signal" connection first, then the earth ring. Until the earth ring connects, any potential difference or stray voltage present on the earth of the connection being plugged in, can result in as much as 50volts being spiked into the input selector chip. I have seen scores of amps damaged by this.
How to avoid it
Before making any connections to your amp, FIRST
