On my marantz sr6400 the peak indicator lite comes on when I play music loud. Will it hurt anything if i don't push the ATT button on. When I do turn it on, the music gets low in volume. Thats something I don't like. So again, will it hurt anything on my receiver.
The ATT button is over-kill, lowering the bass or volume a notch would be better. I'm not sure how that peak indicator function is set-up, if it has to do with the power supply or is just a reference level. Really harm will only come if the receiver is clipping the signal to the speakers, which you should be able to hear.
clipping not a problem. I got 200x3 power amp on the front 3. I'm running Monitor Audio 9i The light only comes on when I play hard rock at loud volumes. BTW my cd player is Nad 541i and my sub is velodyne FSR15
