Hi,


I have my speakers (5.1) wired to a stereo/TV receiver on one side of the room. I recently added a PC & Projector on the other side.


I am wondering what would be the "best" way to set up the system to be able to select the source. And any recommendations on the needed hardware.


Should I run the PC audio output to the existing receiver & switch the inputs?


Or should I add another receiver and switch the speakers?


Or???


Suggestions please.


Thanks!

I'd run the PC audio into your receiver's S/P-DIF input and let the receiver do the switching. Easy and low cost.


Using two amplifiers to drive a single set of speakers can be done with an external switchbox. Just hooking up the two receivers to the same set of speakers will be a problem.

Thanks, that's what I have done.


But to kill the hum I added a Radio Shack ground loop filter, which resulted in a pretty low "volume". Have to crank the receiver way up.


Would be interested in anyone's experience with low cost balanced line converters.


Thanks Again

The computer audio out line runs about 40 ft - up a wall, across the attic & back down a wall. In both walls it is relatively close to 110 lines. Seems to be picking up 60 Hz or has a ground loop from the computer & receiver being on different pwr circuits.


I had similar (but less) hum when I that strung the line across the floor.


I noticed last night that I am also getting vertical banding on some channels of video - a possible sign of gnd loop problems on the video as well............


Thanks
