Soundcast ACT-211 AudioCast Wireless Transmitter for PC, Mac, or MP3 Players

This is my second transmitter. I have been using my original system for about 5 years and it's still rocking. I wanted a backup for use in a backyard projection system. Once used it to transmit from inside a house to the receiver in a backyard approximately 200 feet away. Worked perfectly. If you can still get a whole system I would highly recommend this or if you can't find one the outlaw audio owa3 or the atlantic technologies wireless system. Hope this helps.

I was looking for a solution to stream audio from my computer in one corner of the house to multiple locations elsewhere in the house. I tried several attempts using my 802.11g network, but it always ended in frustration - could NOT get streaming to work consistently if at all. Then I took a chance on these devices, and I am extremely pleased. Use the audio out from your PC, and have a powered receiver + speakers on the other end of the wireless link. They are ultra portable (not battery powered FYI), lightweight, and there's no configuration - the receiver and transmitter just find each other and start talking. It's great.I haven't had any interference problems when using these. And the signal is definitely more robust than my Linksys 11g router provides.I'm thinking about getting a third receiver, even though the instructions say you can only use two receivers per transmitter for some reason. If not, a y-cable and a second receiver, and I'm in business.
