Welcome input on multi-room audio distro

post #1 of 15
Thread Starter 
Hi all,

We are doing an addition and will have access to open walls. When the walls are open, I will be wiring as much CAT6, coax, and security as I can. I also will be wiring for speakers. I plan to wire for 7.1 in the family room, 2 speakers in the kitchen, and 2 speakers for outdoors (maybe 1 in hallway and 1 in d/s bathroom too). For video, I am using SageTV extenders (unfortunately no longer supported).

So for audio, I am starting from scratch (well I have a few shelf speakers) in terms of equipment. But I am on a very tight budget. I would like some input on what I need to get audio distributed to the different rooms / speakers. Ideally I would like to play a different audio source in each zone, but if that jacks up the price, then just one source but able to control on/off/volume in each zone.

I would like input on the best way to do this. I was looking at a Denon 1712/1612 as a receiver (will also be putting all video into it and HDMI out to TV). And of course I will need speaker wire/speakers (can route all to receiver or to basement). And controls for each zone/set of speakers. But what do I need to distribute it? and what is best to control it? Do I run CAT6 to each wall plate? Do I need an amp? I would like to stream from internet, and ipods, computer.

I am behind the times on audio and could use some good advice. Thank you.

Search this forum for lots of examples of "whole house audio" and the pre-wiring that goes along with it.

Focus on the wiring first - if you wire correctly, you can use just about any of the products on the market. You can start simple and upgrade over time, too. And yes, multiple simultaneous sources takes you from a simple "zone 2" setup to a whole house distribution. There are ways to do that economically, but it will depend on what you want for sources, how you'll control it, and so forth.

Take a look at the systems on www,HTD.com and NuVo's sites. (www.nuvotechnologies.com)

Thanks Jeff, yes I have been reading a lot on this over the last couple of days. I have probably read too much and have it all cluttered in my brain. I can't determine if I can do this all off of a Denon receiver and use wall plates from monoprice, or need a centralized control (server) like the NuVo, HTD, Sonos, Control4, Russound and hardware that goes with them. of course i would like a nice system, but sadly cost takes priority (so maybe need to be creative).

Wire for the whole house systems, and you can use a simple receiver + speaker selector/volume control setup in the near term. Then you can upgrade later...

A single receiver gives you one output, and you have to decide how to adjust volume in the rooms (all together, or individual volume controls in the rooms). A single receiver coupled with a speaker selector with wallplates (e.g. the Aton DLA line) is a nice middle ground.

Thanks Jeff, this helps greatly. I will look into such a setup. So I will go with one receiver for one output, but can have mutiple input (ie, CD, FM, ipod -- Pandora if network port?). And between the receiver and the speakers is the selector which goes to the wall plates, which go to the speakers. If I have that right. So no need to run CAT5/6 to the wallpates, just 4 wire?

Correct. But you want to run a cat5e in parallel with the speaker wire to the wallplates. That will allow you to upgrade the simple volume control to a keypad or control panel. That's the "standard" method of pre-wire, and will set you up for using most any of the systems on the market.

Sorry to keep going on this, but if I wanted to play all speakers at once -- up to 13 -- would there be any issue w/ signal? When wound an amp be needed? They will probably be mid range shelf/ceiling/outdoor speakers.

If going right to a whole home audio solution, what would be the cheapest solution?

Also, wiring with CAT5e, I assume this could support HA in the future?

Ok, one step back. Assuming you have a 7.1 setup already, that's a separate AV receiver, just add a cheap stereo receiver/amp to power the other rooms. If not, the cheapest method to do multiple "zones" is an AVR with "zone 2" support and an inexpensive amp for the other zones.

Put in lots of Cat5. Swiss army knife / duct tape of low volt wiring... Expect just about anything HA or A/V distribution related in the future will run on cat5e. At least, except for speakers!

If you go initially with impedance matching in-wall volume control, and a 4 channel amp, from a simple AVR, those VC's are usually installed at light switch height. Leave a few feet of slack in the category cables run to the VC so you can eventually install audio keypads or other controllers at eye height.

You can realistically run 4-6 indoor zones off of 2 amp channels, for background music. You won't need 26 channels of amplification for 13 zones.

If you think you may ever want intercoms, run 2 category cables to the VC/KP location.

Thanks all, I think I would go for an AVR like the Denon 1712, which has 2 zones. That should be able to handle all my video hook up for my main TV. And if i have it right i would need an output from that to an amp, and the amp would take all of the speaker inputs from the "non 7.1" (or 5.1) speakers? From the amp, I would run 4 wire to the volume control and 2 wire to the speakers. I would also run a lot of CAT5e/6, and locate plates at switch height.

This would probably be the most economical setup to achieve the task. If I wanted to get more complex, I guess I would have to move to Russound or Nuvo type system to control the distribution -- and I assume that adds a lot of $$. Anyone care to guess how much $$ that would add. I am pretty much starting from zero on the equipment side, so all will have to be bought (given tight budget I would likely go with the above setup, but I just want to get a sense of what the next step would cost) . Thanks much.

Based on looking at this article
http://www.crutchfield.com/S-YcnxMYs...oom_power.html

I am now thinking about using a new AVR (now leaning to Denon 2112CI for networking, and zone 2 preamp, happy to hear any better low cost ideas) for the main room 5.1/7.1 setup, and run that zone 2 preamp out to an input on a 2nd receiver i have (Sony STR-DE435). I would then run 4 wire to vol controls, and 2 wire to ceiling speakers and pair of outdoor speakers.

Questions:
-the Sony is 5.1 with an A/B. If I have to extra zone, do i run the speaker wire from say L/R front on the 5.1 to zone 1 and L/R surround on the 5.1 to zone 2? Or use the L/R front on the 5.1 for zone 1 and the B pair for zone 2?

-Control: with this setup I can only control vol at the zones, so would have to physically go to the AVR each time to select source and speaker selection. I guess the only way around this is a more expensive distributed audio system. (I forgot, with the 2112CI, does it have an app for control?)

-I assume the Sony would be strong enough for the 4 extra speakers? (it is 400 watts). Would getting a multichannel amp be much better -- while adding some cost.

-Forgot to mention, I think most zone 2 can only take an analog source -- so I assume I would have to run RCA output from ie, DVD and other HDMI inputs (used for the main zone) either to the main AVR, or maybe the 2nd receiver?

Thanks

If the Sony has an "all channel stereo" mode, you could use the surround channels, which would give you more total power. But that may cause some usability issues - try it and see. If not, the A/B speaker connections will work.

I would expect that any modern receiver with an app and Zone2 pre-outs would be able to fully control the Zone2 support from the app. Check to make sure. If you used an inexpensive external amp with "audio sensing" for power on/off, you wouldn't have to go to the AVR at all...

Should be plenty for 4 speakers - most whole-house audio / multichannel setups are in the 20-60W/ch range anyway.

Yes, absolutely. And make sure the receiver will output any built-in (Internet Radio) music sources on Zone2. Should - just double check and/or post in the Receiver forum...

I know I'm the oddball around here, but I'd read the Denon manual several time through before buying it. Most of your questions will be answered in there. For the other Qs, as jautor said, ask in the dedicated 2112 AVS forum.

With the nearly infinite amount of info available online, no reason to get burned.

Agreed, the Denon thread is great, and swayed me to the 2112 from the 1712. And confirmed there is an app. Thanks

Of course, now I am reading more about Russound, mainly CAA66 and CA4. Seems much neater and more useful w/ keypad controls. Yes, more $$. Hmmm
