I purchased a new Prosub1000 by Definitive Technology at a local Best Buy. It's the sub which was in my price-range, and thought it got good reviews. Was hoping to get some technical advice before calling Definitive Technology.
First, here's my setup:
Denon AVR (purchased in 2005) w/ no HDMI inputs, no automatic speaker setup
Def Tech ProCinema1000 center channel
Boston Acoustics bookshelf left and right speakers wired to AVR
Def Tech ProCinema1000 left and right surround speakers wired to Rocketfish rear-speaker wireless kit.
Def Tech ProCinema1000 ProSub using LFE output to AVR LFE input
Blu-rays are played on a Playstation 3 with optical audio out line to AVR
I was initially running just the center channel and two front speakers for the longest time. 3 weeks ago, I purchased the sub and two surround satellite speakers. I installed them, and everything was working perfectly. The sound coming from the sub was amazing. The sub is self-powered, and plugged into a simple AC power surge protected bar, which is plugged into the wall outlet.
I just tried to play Iron Man 2 on Blu-ray, and powered up my AVR and rear speakers. All of a sudden, my sub started a loud buzzing noise. A few things I've tried:
1) disconnected the LFE cable from the sub to see if it was a faulty cable. Buzzing was still there.
2) Changed the AC source by plugging the sub into a different outlet. Buzzing is still there.
3) Changed the location/placement of the sub to rule out electromagnetic interference. Buzzing-- Still there.
4) Plugged the sub into the dedicated power management filter box used to power all my home theater equipment. Buzzing is still there.
5) Checked the fuse in the back of the sub--doesn't look blown.
Soooooo...does anyone have any clues before I check into my warranty?
