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).
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
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.
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
The discussion focuses on designing a simple wireless audio transmitter and receiver circuit to send audio signals to speakers without cabling. An IR-based amplitude modulation transmitter and receiver circuit is suggested, with schematics provided for audio transmission to headphones; adding an audio power amplifier at the receiver output can drive speakers. The transmitter and receiver operate on compatible IR frequencies with low distortion (1-2%). The user aims to wirelessly extend audio from an existing amplifier and speaker setup in a large room to additional speakers without running cables. Commercial alternatives like MusicLites, which offer wireless audio transmission with impressive sound quality, are mentioned but considered expensive and difficult to source locally. The user prefers a DIY circuit solution replicating similar functionality. Summary generated by the language model.
