Will hookig up only 2 channels on a 3 amp hurt the


Hi every one, another rookie question from yours truly, I have a dbx BX-3 power amp which can be ran in 2, 3, or 4 channel configurations. I'm using the amp for my main speakers, and have the inputs connected to my Yamaha receiver. I've attempted to place the amp in a 2 channel configuration for more power as the manual show's,
but I get a slit buzzing sound from the left speaker when I do this. To get rid of the buzzing sound, I've used the 3 channel configuration, but without a center channel. That's still running through my receiver. I hope I'm making myself clear. So, to my quesion. Could it hurt my main speakers by using the 3 channel configuration with out the bridged 3rd channel? Remeber, I'm a rookie
so please be nice.:)

Hi Sean, Every time I have a question, I can always count on you being one of the ones with an anwser. Thank's. You've helped make putting my system together a heck of a lot easier :).
To answer your question, Yes I was bridging the four channels down to two. Here's what the manual said "The BX-3 incorporates 4 monaural power amplifiers, and they can be configured into 2 channel stereo amplifier by binding four output stages into two pairs to drive 2 channel stereo speaker system". once the cables are configured, you just have to move a switch to 2, 3, or 4 channel, dependent on the configuration your using. I purchased this amp while stationed in Germany backin the 80's. Up until recently my whole system consisted of the digital series DBX. I've since sold most of the sound processors and am down to the amp, pre amp, cd player and a range expander. I no longer use the pre amp and expander since my receiver handles all their functions. Thanks once again for you help. DBX
