Is there a simple ethernet bridge for audio?
Submitted by doc on Thu, 11/30/2006 - 02:13.
I'm looking for a nice simple bridge that goes like this:
Audio line in > Ethernet > audio line out.
Two boxes. One at the source. One at the destination.
Context: Helping a neighbor get audio from a stereo system in one room to a stereo system in another room when the only path is the house's structured wiring system, which has Ethernet going to every room and a patch panel in the middle.
We want cheap here. Nothing complicated, and nothing silo'd into a system that requires a PC or haredware dedicated to other purposes (such as, all due respect, Apple's or Sonos's). Just an audio-Ethernet bridge.
Anybody know any?

I too have been looking for a solution to this very problem. The only thing I have come up with is the following: http://www.barix.com but they retail for around $250 each.
There is also the balun option which just converts RCA inputs into CAT5 perhaps with some coils to help balance the signal, not sure: http://www.smarthome.com/7829ss.html which I think someone commented on before.
All depends if you want ethernet (IP) to share the cable or not.
Hope this helps.

This would be SHARING The ethernet with real ip traffic right?
I used ethernet wiring to run source level audio through my whole house from my PC and WiFi mp3 player. I didn't know there were any products available that did that stuff, so I just spliced 1/8" audio jacks into the line and mounted those in wall jacks so I could plug in 2.1 computer speakers in some rooms instead of big old stereos. I thought about using ethernet jacks instead and making little RJ45 to 1/8" and RJ45 to RCA jumpers but decided that while that was cleaner it was WAY more work.
But, my ethernet wiring is dedicated for audio - it's not ethernet, just Cat5. If you're actually using the ethernet wiring for data you'll have to do something complex like the sonos.
What would be REALLY cool would be to put audio on two pairs and use the other pairs for serial control signals. Then you could use a learning remote in any room to send commands to an IR LED on the front of the stuff you're controlling. One pair could control the reciever to switch sources/etc, and one pair could control your MP3 source to skip songs, etc. But I didn't think of that until I'd buttoned it all up and haven't been motivated to open it all up and redo my connections.
Make Some!
I went down to my local Big Box Hardware Retailer and built something just for this. Audio works very well over twisted pair CAT 5.
It takes two pairs of RCA jacks, some CAT5 and some RJ45 plugs. If you're clever, you can use a CAT5 patch cable and skip the crimping-plugs stuff.
Simply solder a pair of RCA jacks to two pairs of wires on each end, making sure your pairs match up on both ends, of course. Then plug the RJ45 end into a "dark" RJ45 run. You'll now have an audio pathway that you can use anywhere you have CAT5 in the house.
Just make sure you don't use the jacks on any segment that's being used for your network, or Bad Things Will Happen (tm).
The soldering takes 5 minutes and total cost is about 20 bucks. I use it to send 2-channel audio and S-Video signals from one floor to another in my home. Works very well!

Hi, nice site! HTML http://www.justurl.com/it-is-to-page-which-very-long.html
must it be Ethernet, or just twisted pair ?
If there is a patch panel then one could connect a Cat 5 line
coming from one room to the Cat 5 line going to another directly,
with a cable that's NOT through an Ethernet bridge, and use a pair
of "baluns" for Audio+Video transmission, one in each room.
Search for UTP+transceiver+audio, they should be around $50 each.

Agreed: line-level audio over UTP
I worked for a firm producing such things in Fremont, California: ETS
http://www.etslan.com/Audio.htm
has the specific type of products useful for this purpose. There are other manufacturers, of course, and resellers that OEM all of these sorts of things. I just happen to be familiar with this one, and *know* the products work. Available as external inline baluns or as wallplate models.
Note that I haven't worked for them since we moved to Maryland four years ago, but they remain friends.

This is it
Yep, that's what I'm lookng for. While it might be fun to build, ready-made is the Easy Way.
Looks like a PA807 (Stereo RCA to RJ45 (pins 1,2 & 3,6)) is what we need at each end.
Much thanks to you, and to everybody else who responded.

Common. Not Cheap
Such devices are quite common in broadcasting now, but they're not cheap. See, for example, http://comrex.com/products/access.htm (about $3,000 per location). ...doug

any audio chat program should do
like gizmo or skype, configured to see each other on the local network. What mac users call bonjour, right? Another option would be to use VLC media player to somehow stream from one computer to the other. None of these options would probably preserve the best audio quality though.
There are some audio plug-ins used for production, like wormhole, that are used to send audio streams from one audio recording program to another (on another computer), may also be something to look into.
A last option would be to use the middle 3 cables from the ethernet jacks, and wire those to RCA or phono plug connectors. Although that signal would be sent to the connectors through out the house, and might not be powerful enough to be picked up at the other end.
