Whole House Question: Left Spkr, Right Spkr, Mystery Cable?

post #1 of 6
Thread Starter 
Hey everyone,

I'm new to whole house audio as I just bought a pre-wired home.

There are 2 speakers in each room, plus a volume dial on the wall.

At the hub, I am getting three cables. One is labeled Left and has both red/black wire wrapped in the sheath. One is labeled Right and has both a red/black wire in the sheath. There is a third wire from each room, cat5 cable from the looks of it but its cut not terminated with a plug.

What the heck is this cat 5 cable for? The home builder told me it's "for the volume control". ?

I am getting zero help from the builder and there are zero manuals.

Is this a common thing....?

Instead of using traditional volume controls it is for a smart keypad which gives you local room source select, volume control, and device control.

Read the 4th post in this thread as I just went over it with someone else...

It's pretty slick, but will cost more to setup than a traditional volume control system.

If your speaker wires are run through the single gang box near the door of each room, then you will find the cat-5 in there as well and you can choose to either use a traditional volume control or you can use a smart keypad.

Yes, it's for a keypad, which is generally part of a whole house audio (WHA) system. The fact that the cat5e cables are there mean your builder wired the house "correctly"!

The category cable could also be used for distributed IR, from the VC location; cheaper source control than a Smart KP.



If the speaker cables run to the VC location before running to the speakers, an ABus or Digi5 system could be used. Not a premium solution, but on the cheaper end of WHA systems.

The category cable could also be used to supply an iPod/dock as an audio input, or power an on-wall/in-wall tablet, iTouch, or conventional phone dock.

Thanks you guys are awesome.

Any idea how I would 'test' the cat5 cables? Any way for me to test one room at a time before I invested in keypads or something?

Are you concerned about the cables being damaged? You can easily test them for continuity, but it will be time-consuming. I wouldn't worry about it - but if you intend to buy a keypad-based solution, you can terminate both ends with an RJ45 and use a network cable tester to make sure all 8 wires are good.
