Noise in one channel


Newbie here, both to the forum and to high quality home A/V.

I have a two year old Emotiva Fusion that was never used.  I just purchased KEF Q300 and Q600 and have some old Onkyo surrounds.  

Upon install, I have been hearing intermittent crackle/pop sounds from one channel (FL).  I assumed I had compromised speaker wire somewhere so to confirm I swapped Center and FL channels at the receiver.   The sounds followed the swap and began emanating from the Center channel.   I believe that points to the amp circuit from the receiver, does it not.

What are my options to fix or further isolate this?

thx,
Stevie

i see. you might want to check/re-apply solder on input and output terminals of FL channel. re-apply to all of the inputs
if that won’t help, it’s perhaps noisy output transistors(or amp modules whichever applies). usually they may have hotter temperature than on all other channels.
