I have a doctors office that wants 2 TV's in the waiting room with 2 sources and headphones that can toggle between the TV's audio depending on which one the listener wants to hear. Does anyone know of a way to do this? The distance from the source to the listener is approx. 50 feet.

Thanks

Check out Sennheiser, not sure about the switching though.

For some reason I thought Pico Macom dealt with this sort of thing but I was wrong. I remember someone mentioning taking a fm modulator and broadcasting within a building but cant remember the details.

Thanks anyways I guess they will have to have to have certain headphones attached to a dedicated source.......????

Pico does make an fm modulator that is installed in health clubs around the country.
Fixed line level in, you choose the fm frequency out. Works great....

I called Pico and talked to Terry J. and he said he didnt have anything capable of doing what I wanted. He said his stuff was only capable of modulating baseband into coax on the FM band 88-108. He also said you couldnt really broadcast FM due to FCC regulations. Is this wrong?

Even if I could broadcast something in there would I want to around all that medical gear?

Let me ask a question. Could I take a FM modulator from 12v car audio like the ones used on modulated changers and take the antenna out from the modulator into a car antenna to broadcast within that building? The only thing is I would have to have a pair of headphones that could select certain frequencies depending on what I had it modulated on as well as have a modulator with more than one frequency output and multiple inputs. I guess I would have to take two modulators with a far enough separation frequency to keep them from interfering with each other.

I might just tell them they cant do it and save myself some grief.

Thanks for the responses

Technically, Pico is doing a posterior protection move. Setting up your own broadcast system is potentially something the fcc might frown upon, and so I'm not surprised by their response. Frankly, they've told the same thing to me.

I can cite a racetrack in Wisconsin, health clubs throughout the midwest, on a large street in NYC, and more as systems I have engineered.

Clearly, it's in your best interest to decide whether you want the job or not. If you do, then I know the Pico works. It does require some skill to install, and you will need to rely on your Pico supplier to give you support, not Pico themselves.

There is a way to do this with Sennheiser, we've done it. The only problem is it was about ten years ago, and I'm hazy on the details. It was pretty cool, though. Two sides of the Master Bed, and each had an individual LCD panel on an arm. They both had a pair of Sennheisers, and each was powered by the same brain. I think it had something to do with balance control. One pair was all L and the other was all R. Ended up being quite slick.

Wouldnt both signals play through the headphones, one on the left and the other on the right at the same time? So I would hear TV1 through my left ear and TV2 through my right? The only way I can see the balance doing this is listening to only one side of the headphones at a time. Did I miss something or is there more to this? Thanks,

There was some kind of switch on the headphones that was some sort of L,R,L+R switch. (remember, I'm kind of hazy on the details...) If you set the switch wrong, that's exactly what happened. (TV1 in one ear and TV2 in the other). Either could be set to listen to the other. The base had two spots for extra batteries, so they were never down.
