You guys are missing the point.
His room is wired with all the speaker wires located in the rear, that's why is A/V receiver is located there. He does not want to go thru the labor and expense of moving all the speaker wires to the location up front with the rest of the A/V equipment (and maybe there isn't room either?).
He could locate all his source equipment where the A/V receiver is, but that also would require pulling more wire from there to TV (and depending on length and how the wire has to run - baluns). Again, labor and expense he doesn't want to spend.

It is what it is, until he wants to get more serious with his setup.

Well, if all of his speaker wire is in the rear, how is he getting sound to his L/R/C? I would think the speaker wire must run from the rear to the front for that, no? Could easily change the direction of those to connect to an AVR up front and have those speaker wires feed the rears - if that's the case.

I'm sure Directv can't wait to get their hands on your unit.

I didn't mean for this to become a major discussion and I apologize for not being as clear as some wanted.

Because of the configuration of room ( and that the stereo equipment was there before the TV) The TV and the receiver are about 10-12 feet apart in a straight line. 2 Rear speakers were wired in place during a room remodel and those lines run through the walls, and under the floor and back to receiver.

Wires to center and sub woofer go from receiver under the floor and come back up behind TV. L&R front speaker wires are under the floor from receiver and come up at the speakers.

The 2 audio lines now run from A/B box under the floor and back up to the receiver.

Everything works and the sound is better than it was a couple of days ago. When I get the new TV it may, or may not, be viable to move stereo equipment to the same stand as TV. It is not a question of money or putting in the effort. It just may not work.

I understand that there is some line loss because of the length of the runs but I have to wonder how noticeable it is.

There are limitations in the room that will eventually determine what happens here. I accept that I will not have the best sound experience but I would like the best possible sound based on what I have to work with.

That being said, couldn't you have your A/V receiver with your TV? You could connect the center, sub and L/R speakers directly to the A/V receiver, and use the current speaker wire that goes to the back of the room for your rears (even if you have to splice)?

Might make things much simpler.

I'm sure Directv can't wait to get their hands on your unit.

It might .......but would there be enough of a difference in sound quality to make it worth doing?

In all probability, yes.. In looking at a picture of the rear panel of your receiver, it appears that it has two component inputs, two optical audio inputs and two coaxial audio inputs.You didn't state whether your A-B switch is an auto switch, remote controlled switch or manual switch, but you might not need it. If you connect the component output of your DVD player to one of the component inputs of the AVR (and optical output of the DVD player to one of the optical inputs), and the component output of your satellite receiver to the other component input of the AVR (optical output of the satellite receiver to second optical input on the AVR), then connect the component output of your AVR to the component input of your TV, you would have the best possible combination of sound and video quality and do without the A/B switch.

If the price is not an issue, and the effort will not be a problem and doable, and there is room for you Sony amp to go with the other source equipment (Sat box & DVD); then yes... rewire and move that Sony amp to the other equipment. That is the 1st thing you should do.
Having an A/B box in the system is adding 1 more component that can fail, taking up space, complicating the operation of things, degrading performance, and if you move the Sony amp to the other equipment, not needed.

What you still have not stated (and some are assuming one way or the other), is how you have these devices hooked up? Meaning:
Audio = Are you using digital out from your sources to the digital audio inputs on your Sony Amp? Or are you using analog audio connections (left & right / white & red RCA)?
Video = HDMI into TV from sources, component video (red, green, blue), composite video (yellow)?

When you get your new TV, it will most certainly be a 1080p resolution of some sort. In order to get the 1080p signal to you TV, it has to hooked up with an HDMI cable. Your current Sony Amp doesn't do HDMI switching but that's OK. You just connect a HDMI cable from each source to TV (TV does the video switching). Then a digital audio cable goes from each source to the amp (amp does the audio switching).

Unless you want a stack of remotes laying around to switch everything, you NEED a universal remote control.
You push the button to watch satellite = The remote sends out the codes to switch the TV to the correct input, amp to the right input, and is ready to work the satellite box (with volume working the amp). Just 1 button push.
You push the button to watch DVD/Bluray = Same thing, everything is set to the right inputs on the TV and amp and is ready to work the DVD/Bluray player (with volume working the amp). Just 1 button push.
Hit the OFF button = Everything turns off. Just 1 button push.

I'll let the rest of the guys advise you on what universal would work best for you, that you could program yourself. I generally only work with the more professional remotes that are more expensive and require more indepth programming from my laptop. Regardless you can get a good universal for less then $99... maybe even less than $50 that will do what you need.

Note: Whatever new TV you get, make sure it's controllable! Meaning it has discrete codes for on/off and input. A lot of cheap TVs don't, they only have toggle codes for power & input. That would be a problem for a control system (universal remote). Your Sony amp responds to discrete codes, so you are good there.

The audio connections are analog. The tv doesn't have an HDMI input (its a Hitachi projection that predates HDMI) IT does have an input that they call a DVI HDTV input. The connection looks like the Kind used on CRT monitors. I have an HDMI cable out of the DTV box to an adapter that is plugged in there

With the new TV moving the receiver may be possible. One issue will be space for CD player and turntable, yeah I still play records.

I appreciate all the help

The audio connections are analog.


And there is yet another issue you have. You are not getting 5.1 surround sound, even thou everything you have is capable of doing it. It just isn't hooked up correctly to do it. You need to hookup the digital audio outputs from your sources to the Sony amp's digital audio inputs.
I won't even get into it here, as it would take pages more discussion. But I will bet you top dollar none (or at least most) of your speakers are not setup properly either.


If you really want to get everything right (the way it should be) and get the best picture and sound out of your system; it is going to be a long road to go down. You have a ton of stuff you are going to need to learn and know to get there. And since you seem to be starting out at the most basic level; it will probably take you awhile to research everything, ask the right questions, get the answers you need, and act on it.

One of the biggest obstacles you will likely run into, is getting the advice you need. There are many great books and publications you could buy. However that can get expensive (you could have hired someone for the price). The cheaper way of course is the forum boards. But it should go without saying " you are on the internet". Everyone is a self proclaimed expert, even thou many have no idea what they are talking about. You have to look closely at who's giving you advice.
Everything in this thread so far from everyone has been great. But that won't always be the case when your asking questions, sometimes you will get conflicting answers.

My favorite line: "Rocket science: it's just throwing fuel in a tube right!"
A/V systems are VERY complicated. It only seems simple to someone throwing something together that just makes noise and has colors on a screen. It's FAR more complicated to get an accurate sound reproduction and an accurate picture on a video display. 80%+ of people who have systems in their home, fall into the noise & colors category.

When you refer to Digital audio input/out put are you referring to optical cables http://www.newegg.co...N82E16812120019

Getting the colors right is another discussion when I get the new TV

Toslink is one type of digital audio. HDMI is another.

DVI carries all the video information that HDMI does (often including the HDCP copy protection stuff). This is the connection of preference if it supports HDCP as this will become a big issue going forward.

When talking about making long distance connections, TOSLink (optical) is a poor choice as the emitters and cables used are typically not of good quality. Coaxial digital is usually a better choice (if available).

So TOSLink is good for short runs-the equipment is close to each other?

What is the difference,if any, between coaxial digital and coax?

Thanks

I wouldn't say that it was good but rather that it is sufficient.

What is the difference,if any, between coaxial digital and coax?

Optical is optical and coax is electrical. Coax works on voltages (with very little current) where optical works, typically, using LED light and cheap plastic optical pipe.

If you have the option of coaxial DIGITAL, it is usually the better choice. If you have to parcel it out, use coaxial digital for your best sources (Blu-ray, DVD) and optical for the less wonderful sources (or the ones that don't have coaxial digital outputs).

There is much Internet traffic on the subject of coaxial digital versus optical if you really want to fill your head. Many discussions center around the term "jitter".

Your best sources for audio/video cables are monoprice.com and amazon.com.
Here is a link to optical cables from Amazon. http://www.amazon.co...optical,aps,163
I have used both the Amazon Basics and Mediabridge cables and find both to be well made and inexpensive. I've never had the need for an optical cable longer than 6 feet.

As to the difference between coaxial digital (coaxial digital audio) and coaxial (radio frequency and video coax) -- the former is a lightweight and more flexible form of coaxial cable, normally terminated in RCA type pin connectors. The latter is heavier, less flexible cable made according to industry specification (such as RG-6, RG-8, RG-11, RG-59 amongst others (RG-59 and RG-6 are the types normally used in consumer electronics and are terminated in "F connectors")).
Of the two types of digital audio connectors, optical is the most commonly used.
