Hey all - was hoping y'all would have some advice for a friend of mine. He recently had satellite TV installed and when he hooked it up to his HT system, he said his subwoofer started humming big time. It was like it was getting feedback from the satellite signal and he wasn't sure what was going on.
We think the culprit is that he has a switchbox at his TV to select between the satellite signal and VCR signal. He has a VERY old TV that *only* has a co-axial input (no RCA composite). So he installed a co-axial switchbox that allows him to choose between the satellite (antenna) signal and the VCR signal.
Here's how everything is hooked up:
video:
DVD ---RCA---> VCR ---co-axial---> co-ax switch ---> TV
audio/video:
satellite box ---co-axial---> co-ax switch ---TV
audio:
DVD---digital co-ax--->receiver
VCR---RCA--->receiver
receiver--->5.1 surround speakers/sub
Granted the easy solution is to buy a new TV that accepts S-video/composite hookups, but he's still looking and not ready to buy yet. However, for the time being, can someone tell him why the sub is receiving feedback? Is there anything he can do to get rid of it? Thanks for any advice y'all may have.
Components:
Denon 1603 H/T receiver
Ascend Acoustics CBM-170s fronts/rears
Ascend Acoustics 340c center
HSU VTF-3 subwoofer
unknown brand of DVD player, VCR, TV
