Page 1 of Home ceiling speakers - old (9yrs) audio input...

I bought a new house last month and all the rooms have integrated ceiling speakers and a small wall mounted control unit in each room.

The living room has the main control unit which appears to have an audio input but I don't recognise it.  The house is 9 years old and I think all this was installed from new.  It only plays the radio at the moment so I'm keen to find a way to utilise the speakers with another sound system like the Sonos.

Does anyone know what the audio input socket below is?  

The manufacturer, egiaudio, appears to be a Spanish company and the website isn't great!

The speakers in the room could be awesome but they just aren't being used to the best of their ability yet!

Cheers

I used to fit these sort of systems a decade ago in upmarket houses, they are totally hard wired. Not wirefree systems like nowadays, with picture hanging speakers, etc.

Each speaker or zoned speakers in a room or area (more than one on a zone) is wired way back to a room controller, that should be off/on and volume control (I bet), and all the pairs of speaker wires (per zones) go back to the main controller. So signal is derived at the main controller.
 
The 7 pin audio input socket was for a seperate record turntable.

If you feel the speaker system is working fine, and room controllers are working OK, then stick with the hard wired system, and you could buy a modern main controller, with radio, CD, Ipod dock, etc, where you would connect up to the old wiring in the existing zones.

If you want to keep and modifiy the existing main controller audio input socket to a modern aux socket, it can be done, but get an audio guy to do it, as the 7 pins are power/signal & earth to/from turntable. You would want it changed to  accept a modern compatible signal in.

It looks like a 7 or 8pin din connection used for keyboards and Synths etc, If that's any good.

Edit - The Unit you have seems to be an EGI Domos C14f, i couldnt link the manual for you so ive added it to my dropbox.

It might be this:

Or it might be a custom input, depending if it's stereo or multi-channel. With a meter you should be able to detect if it's that as pins 2 and 7 should be shorted and most likely connected to the shield.

If it takes balanced inputs, it might be harder to work out, but you could try feeding it a very low level signal on various pin combinations and see what noise comes out.

Cheers guys.

I'm going to buy a 3.5mm to 5 Pin Din cable and see what results I get with that... Also nice to see in that manual enemyonpc linked to I can get a white face for the wall unit (it's a smokers white/ivory at the moment).

I'll let you know how it goes.  I've got a brass wall control in every room to replace now (10 the size of a wall switch) as it doesn't go with the brushed chrome sockets/switches I spent 7 hours last week fitting!

Thanks again guys!

I tried the wire out last night and it was perfect!  I now have my s***e music pumping out rather than the radio! :)

Just another 1000 jobs to sort out now to get the house finished and I can sit down and enjoy the music!
