Adcom question. Need help

boston1450

Hooked up the Adcom today. Sounds wonderful. Playing around with the buttons I noticed when balance knob is in middle both speakers are working & sounds perfect. Turn balance knob to left nothing/no sound at all---Turn it all the way to right & both speakers are both working--vs just the right speaker...Any thoughts besides leave it in the middle. Lol (where both work fine)

---

also. There is a little button on back by speaker connect that is adjustable. Where should i keep it set at---i did no research on this & thought i would just ask here--- hooked to my SDA's only. TIA randy

Randy- Could you post a pic of the back? A lot of times there is a output level adjustment on each channel. If that is what it is, I would run it maxed out and control volume with the pre.

As to the balance ?... could you try gently removing the plastic knob covering the actual shaft and see if you can hand turn the knob all the way left for left and right for right only. Bring it back to the indent indicating center/equal balance and replace knob with indicator pointing straight up. If it still has the same issue, I'd try using some deoxit spray (access the hole on the shaft inside the chassis by removing cover) and working the shaft thru full motion multiple times to see if that clears and oxidation or crud issues on the contact. Other than that I don't have any idea why it would do that. Good luck working it out.

BINGO. THATS WHAT IT WAS. I thought i put switch on stereo. It perfect now

one more question. Should i turn amp off first. Or pre ? Thanks a bunch

Attachment not found.This Adcom is incredible on SDA's

No scratchiness at all. In balance or volume. It was the switch. Huh. Little things matter. I dusted the fins on back n must of hit it. I know for a fact i put it on stereo. I know nothing about bridging.

Thanks. That is a big big help there. I knew there had to be a order in on-off operation. I will learn that THANKS AGAIN

Isn't that combo great. You have a winner amp great speakers and a resolved pre/amp problem.Good stuff,clearly a fan of Adcom and when my cable issues are resolved I just might look into an Adcom pre to match.

I may add a Adcom tuner down the road, but for now all i have to say is ive been missing out..these amps are very nice clean sound. I was worried i wouldnt like the sound..but well worth the money

Glad it was a simple fix and you are enjoying it.

Randy, which pre to you have and what are your thoughts on it compared to your other AVRs or 2-ch receivers?

Congrat's on the new-to-you setup! :cool:

Thanks for asking. I listened to it for about a hour before the misses got home & there is no comparison.(although receivers work nicely too). It seems the quality is more cleaner. Robust. I brought it to 10:00 or so. and sounded very good to my ear. I listened to some N Young on the Nakamishi 500 & perfect. I hope to play around some more today with it & adjust some of the buttons. I need to research unit as i didnt get a manual for it. I do not listen to music at high high volumes anymore. I find it relaxing to put it at 9 oclock and sit back & enjoy it
