Hens, Sometimes, perhaps one out of every ten 'power ons' the amp will emit a little vibration/rattle but then settles down to dead or near dead silent operation. I don't have any abnormal quirks like sound cutting out, volume change, run hot, harsh distortion, it operates fine imo. However, I don't have it on a test bench w/ test equip and would not know what to do if I was in such a sutuation. Question, amp and recv'r both have pwr cords that are 2 prong male/2 hole female. The cords are removable type but only 2 terminals vs 3 ? Perhaps a gnd issue? I assume the manufacturer designed it knowingly. Amp list 2k and recvr list 3k new. Although I did not pay that much. Should I forget about it and just crank it/enjoy!?
added amp...now hiss from spkr's
Addd an amp to the mix. SS multi-ch. Had no problems prior in relatively simple rig or atleast I did not notice. After making connections to recv'r(now used as pre/pro) I noticed a slight hiss/static like sound comimg from mids on my spkr's. So the process of elimination/isolation began. Long story short, I narrowed it down to the hiss/buzz coming from spkr's with only the amp connected. Nothing else...no interconnects no nothing. That cancels out cable problems, bad dvd player, etc, etc. Just power cable plugged in and wires going from amp to spkrs. When powered on it makes the noise. Amp runs quiet as far as I can tell when putting ear next to it. What's the deal? Tried diff outlets, diff spkr...makes no difference. When taking amp out of the mix and connecting spkr's to recvr, there is no noise at idle. Amp plays fine/sounds fine but the noise, although slight, is bugging me to pieces. Amp was shipped to me and had shifted cady/catty corner while in it's factory packaging which is pretty substantial. Perhaps it took a hit/drop...weighs about 80 lbs! Could something have gotten jared loose...a transformer which it has two of and quite large. Or is it the nature of the beast to output some noise when at idle? Thank you.
