Wireless Audio transmission

post #1 of 11
Thread Starter 
Here is my dilemma. I am going to be purchasing a new projector that will be places at the back of my viewing room. I will have the cable set top box back there as well and i would like to hook the hdmi up to the projector from the cable in the box but somehow transmit the audio (without a wire) to the front of the room where the speaker will bad near the screen. MY thought is to get one of those rf link 5.8ghz wireless av transmitter receiver packages and hook the transmitter up to the rca LR out of the cable box and then hook the receiver up to the speaker in the front of the room which has a RL rca input. My question is 1. will the cable box output on both the hdmi and LR RCA 2. Will the RF LInk transmitter / receiver send just audio 3. Does this make sense. Thanks

You might want to consider the Amphony 1500 (http://www.amphony.com/products/l1500.htm). I just got one and in my initial tests I have found it to be quiet and reliable. It is designed purely for audio which it sends uncompressed.

thanks that looks like exactly what i need. What is the difference between the 1520 and 1500?

THanks for the headsd up on that. Is there a audio device switch? similar to an hdmi switch but just audio rca LR plugs.

The 1500 receiver is designed to plug into a receiver and has RCA connectors, the 1520 contains an amplifier and has speaker connectors.

For audio switching you could use something like this:

I appreciate all the help. I ended up getting the Amphony and a rca switch and they should be here next week. I will let you know how things turn out.

Any reactions/reviews of the Amphony yet??

I'm wondering if there's any delay in the audio transmission. I know this would be difficult to test without a wired connection to compare to.. I've installed a wired whole home audio system in a home with 3 surround sound rooms. Now that the house is done, the homeowner is telling me he wants the whole home audio music in the home theater rooms also. I could use the Amphony, but it would be useless if there's any sort of delay between rooms.

The specs show overall audio latency of 1.2ms

Which is the time it takes sound to travel a little over a foot, so it's not significant.

Yeah, hopefully it won't be much different from the wired Xantech Digi5 system
