Anyone done this successfully? Success being NO hdmi issues, bleed over, etc?
Chasing Ernie's post count, one useless post at a time.

Purists will scream and yell, but I have about 200 rooms with two HDBT inputs, two HDBT outputs and a 45W 70V cable bundled together for at least 10' with no issues. The real question is how long are the runs in proximity and how much power is being drawn from the speaker circuit...

It is a tuff one to say.

I've seen cat5 cable that someone installed with a bundle of Romex, wrapping around it, going thru the same holes, the entire run of cable (about 40-50 feet). Put a cheap HDBaseT extender on it and it worked fine.

Then I have a house I'll prewire with Cat6, keeping it away from everything, put in a good HDBaseT extender (tried a couple of good brands)... and every time the customer turns the lights on/off the picture blanks for a few seconds. *facepalm*!!!

I wouldn't think a 70V system would cause you any problems. But it's HDMI so....

I have seen problems with 70V in proximity to line/mic level audio that was laying over a ceiling. Any time I have a choice, I keep cables with high impedance or weak signals separate from higher voltage or current.
My mechanic told me, "I couldn't repair your brakes, so I made your horn louder."
