Question about Audio Players & Recorders
I just purchased a panansonic home theatre system and with everything set up there is a constant, not so loud noise comming from the centre speaker only and its constantly there. Its only from the centre speaker.
What a very disappointing experience to have this happen.
Check the cable 1st. If this speaker is powered, you could have a bad shield, or the power is causing a ground loop.
If the speaker is coming from an amp using speaker wire ie: 2 lead + - check the connection and make sure no fraid strands are touching each other on the rear connection.
In addition check your TV, Ap, And speaker system (if sub is powered independently) are all on the same curcuit.
a certain cause for ground looping resulting in hum.

-Shorting (bare wires touching) of positive and negative speaker wires.
-Using speakers with an impedance lower than that rated for this unit.

-Using the unit in a hot environment without proper ventilation.
