Digital Coax Audio - Interference from ZWave Dimmer?

1106 Views 4 Replies 4 Participants Last post by  crutschow
I don't know the best place to post this but I will try here first.

I send digital (coax) audio via RG6 cable from the PC in my basement to the AVR in my family room (~30 feet). I have an Intermatic ZWave dimmer switch in my family room. When I turn the switch fully on or off there is a temporary interruption in the audio signal. When I dim the lights some the signal is permanently "interrupted" (no signal at all received at the AVR). There are also "blips" in the signal when the air conditioner turns on. I have a pair of Cat5 baluns for digital audio that I tried instead of the RG6 but still have the same interference.

Is there anything I can do to prevent this? Thanks.

try optical spdif instead? or check for ground loops or anything of that nature that could be causing the issue.

I've had similar problems for years with HVAC turnon and things like that, and occasionally if I grounded myself on computer case and got zapped. Now that everything is HDMI or toslink its no longer a problem though

Unfortunately coax is the only option at the moment. Thanks for the responses.
You might try an isolator such as http://www.amazon.com/Viewsonics-VSI...ref=pd_sim_e_2 .
