Phil,
I've tried every available outlet in my condo. And it's the same in every room. Turning down the mic input level was one of the first things I did, and that did not help. I later found that static is also present in headphones, and in the output jacks. The noise comes primarily from the tweeters. The speakers I used were a PC based set up with two satalites and a subwoofer. The sats didn't have tweeters so the noise wasn't as loud because the tweeters weren't there. I then hooked it up to my stereo system, and since those speakers have tweeters the sound was louder. I'm beginning think it's an internal problem with the amp. It's possible it got damaged during shipment. Currently I don't know what the heck I'm going to do. I spent a good chunk of change on the board and right now it's unplayable in my home. I don't know anyone who's qualified enough to open the thing up and take a look. The nearest authorized repair center to me is hours away, and I have no idea what they'd charge. I also don't know what Yamaha would charge me either considering the boards not covered under the warranty anymore.
