I've got some questions about connecting existing wiring into my receiver for whole house audio.
Here's what I have:
The existing wiring in the room has 2 sets of simple 2-wire cable run from wall locations to a junction box. Then a single simple 2-wire cable runs from the junction box to the receiver cabinet. Four rooms of the house have this same set up.
I'd like to run these speakers off zone 2 of this receiver for music only as an audio tech connected the home theater to zone 1.
My main questions are: how do I connect this to have both channels represented with only a single 2-wire feeding each room, and further, how would I connect a speaker selecter/powered amplifier to be able to control the volume to each room? Rewiring to each room is really undesirable since there is rigid wall insulation.
Suggestions for a speaker selecter/powered amplifier are appreciated.
Thanks in advance for any assistance. - Brett
You'll probably want to double check, but I believe running 4 speakers off of 2 wires brings you down to 4 ohms, so you need an amp that is stable to 4 ohms.
I have a similar set up and just added two speakers for zone 2 for my Yamaha RX-v673.
Probably the cheapest way to have zone 2 sound would be speaker selectors in each junction box. This would allow you to have one of the pairs of speakers installed playing zone 2. You'd also need a selector at the amp. Check out the speaker selector at htd.com.
The next step for my system is a multi-channel amp. I am going to go with a MCA-66 Multi-Zone Controller/Amplifier from Home Theater Direct. Over the years, I've purchased in-wall and in-ceiling speakers from this outfit and they always get good reviews and are responsive to questions. (other than buying some of their speakers, I have no association with HTD)
Again, I'd double check, but I believe the 6-zone amp would handle all 4 rooms. Each 4 speaker room that is wired together would be able to be an independently controlled and sourced zone. If your Yamaha has a zone 2 pre-out, you can plug it into the MCA-66 and it can be one of up to 6 sources.
You could be watching a movie in your home theater and have background music playing everywhere else in the house, both sourced by your Yamaha.
I would double check with Home Theater Direct on your specific wiring set up, but it sounds like you'd be able to run your system with the MCA-66.
An additional option you could have with the MCA-66 set up (similar to what I will do in two places) is to put a volume control at the junction box for one of the pairs of speakers. This would allow for a kind of cascading volume control. The master volume controlled by the MCA-66 and then sub-volume control for the 2nd pair of speakers.
In my case, I am putting a pair of speakers on an enclosed patio and a pair on the outside of the house for bbqs. I am going to put the volume control for the outside speakers in the patio leading outside. I'll only want those speakers on when we are having a bbq. However, the speakers on the patio will be on more often. This allows me 2 purposes for one zone. When you move beyond 6 zones, the cost jumps up, so I've laid out my system to only need 6 zones by the time I'm done with it.
I've been researching whole house audio for a while, and the HTD equipment is, by far, the least expensive set up that I have found.
I do not yet have the MCA-66, but I just added some of their 8inch in-ceiling speakers for my zone 2 off of the Yamaha and to me the sound is clear an crisp. My wife also likes the sound of the speakers. I'm planning on picking up an MCA-66 around summer. I've got a trip to Hawaii to pay for first, otherwise, I would have gifted myself with an MCA-66. :-)
