Dear Steve

Thanks for your help ,I am not able to open the link ,also I need to ask you please the transmitter cct you send has the same frequency that the receiver has ,I mean can both communicate under one frequency

Very strange -- I was just there. Perhaps the site is having temporary trouble. Maybe try again tomorrow. The medium is IR. As far as I can tell, they're compatible.

OK the site is back. It's an amplitude modulation IR transmitter with an IR receiver. Very simple, but they claim 1 to 2% distortion, so it's pretty good. Don't know if it's good enough for your application (you didn't offer much information).

Hi Steve ,

I can now open the site ,I need please to give you more details on what I am planning to do ,I have big room that has one speaker for announcement connected by cable from one amplifier ,I need to add more speakers but I do not want to put cabling from the old speaker to the new speakers ,so I thought if I can do Tx and RX CCT and I connect the TX board to the old speaker and the RX board to the new speakers and whenever there is any broadcast the new speakers RX the audio by the RX board

I was at Lowes today and saw something that might apply to your problem. It's called MusicLites:

But, they're rather expensive. A transmitter is $100 (there are various, so research it) and each MusicLite is $200-$250. But, the sound _was_ impressive.

Steve ,thanks alot ,

it was great ,but i am in QATAR ,and it is not that easy for me to buy ,i am looking to do the same that Musivlite do , so i still looking for CCT tha i can do bu my self .thank you very much for you help
