Q: I want to locate my speakers in a place where it’s difficult to run wires from the sound source. How can I do this without wires?
A: Yes, here are a couple of different ways to do this. The first uses FM radio waves, and the second uses IR, or infrared. Each has it’s set of characteristics, and work with both audio and video – although it uses a composite connector, so it degrades hi-def picture.
I tested the Terk LF-30S, and found that my 2.4GHz cordless phone interferes with it. As long as the phone was on, the unit had a lot of static interference, and was unusable. The reviews at the Amazon page listed below are revealing as well, however I did not experience the interference with my wireless network that these reviews mentions. The sound was very good – more than enough quality to stream radio.
- Terk Technologies Leapfrog LF-30S Wireless 2.4 GHz A/V Distribution System
- 2.4GHz Wireless AV Audio Video Sender IR Transmitter & Receiver
The above two products work with FM radio technology operating at 2.4 GHz.
Alternatively, there is a different product I found that uses infrared (IR) operating at 5.8 GHz. If you have devices that interfere at 2.4 GHz, then you would want to use this type instead. This also will transmit 450 feet, while the above products transmit up to 150 feet. Both will go through walls and floors without a problem.
