(Not quite sure if this is the correct place to post this. If anyone advises, I'll put elsewhere within the forum.) We are building a home gym and I'm looking to install a wireless transmitter - from the HDTV's and receiver to a wireless receiver which attaches to each of the following; (1) treadmill (2) stationary bike, (3) cross trainer. The receiver usually is a little box that has controls (ie, channel changing and volume) - one plugs their headphones into the jack on the receiver. This way, my wife can be on the treadmill with her headphones listening to one TV, while I'm on the bike listening to a different TV (we have 2 TV's in gym). Does anyone have any recommendations regarding equipment or companies for this??? My gym uses Cardio Theater, but can't find anything else. Thanks for your input.
