Can it hurt a 5.1amp only using left & right chnls


Hello

Can anyone tell me if I am hurting a 5.1 channel amp by only using the front left and right channels for output.
Its a Harman Kardon avr 525 it always has run a little warm.
I am using it for stereo sound only.

Nope, just turn off the unused channel in it's menus, if possible. Will be something like 'no' in the places where it lists the crossover slopes Won't damage anything either way.
