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 swapped speaker wire leads from Center channel to left front and vice  versa....the noise moved to the speaker that now was plugged to the left front amp channel....the original speaker was quiet.
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.

My Emotiva receiver is still under warranty so I think I can either call in a warranty claim or get an amp and relieve the receiver of those duties....correct?
