Can no longer hear music through loudspeakers, unless I crank volume to maximum; even then, I can barely hear anything. Headphones work fine, can play tunes as loud as I want.
I had attempted to connect my imac computer, via RCA cable, to the NAD receiver. Foolishly, I started plugging into each jack, to see which sounded the best. I also plugged into the 'pre-out' and 'main in' jacks, without turning off receiver. (I later found my instruction manual, which stated I should always turn off receiver before plugging in/ pulling out cable from these 2 jacks).
Not sure if I screwed things up because:
(A) I plugged cable into these jacks, or (B) I didn't turn off receiver when connecting/ disconnecting cable from these jacks
Any idea what might be wrong (besides the fact that I should never have messed with the pre-out/ main in jacks)?
