TV Speaker for Center Front Surround

Threaded View


I think I've answered my own question but thought I'd verify:

I'd like to use my HDTV speakers as front center speaker for
surround sound.  I was thinking I could connect my receiver's
speaker output for the center front speaker to the audio
input of the HDTV.  Seems to me the HD Tv's audio input
has a 1v peak to peak limitation and this would likely harm
the input circuit of the HDTV or possibly blow the channel
driver out of the receiver.  That would be a bad idea, right?

I'd like so save the expense and space for a separate center
front speaker.  Any other ideas?

Re: TV Speaker for Center Front Surround




Your HDTV has "audio in" RCA type plug that can be used if your receiver

has "pre-out" connectors. Just run a cable from the center channel

pre-out to the audio in on the TV. The problem might be getting the TV

to recognize two input sources if your TV doesn't have the right setup:

one for your video source (DVD, Sat, Antenna, etc..) and one for the

audio. So depending on the TV inputs it's do-able.  

List what type of TV you have and if your reciever has pre-outs and

I'll try to help.

Do not try to connect the reciever's center channel speaker wire to

anything on your TV. Smoke from the back of a TV is never a good thing.

I've a Hitachi 51UWX20B.  I've a Pioneer VSX-515.  I've not noticed
any preouts.

Re: TV Speaker for Center Front Surround




Thunder,

You're correct, your Pioneer does not have pre-outs. That makes it more

difficult.

What is the source going to be? DVD player, SAT dish, cable box? Send

me the model and I'll try to see if there's a way we can accomplish

what you wnat.

I'd like the sources to be the DVD and Cable Box.  I can get digital
from either and DTS from the DVD.

Thanks for the help, as I'm just now coming up on this stuff.

Re: TV Speaker for Center Front Surround




Let’s get the DVD to work first because even though the cable says

digital it may not carry a 5.1 signal (mine didn’t) so it’s another

issue.

From the DVD there should be both “digital out” and “analog out”. Hook

the digital out (either optical or co-axial) to the Pioneer. Then hook

up the “analog out” from the DVD to the “audio in” on the Hitachi. It

should be on the same input connection that you’re using to route the

“video out” from the DVD to the Hitachi (DVI, Component or S-Video).

Now play a DVD with the Pioneer off. You should hear the movie from the

TV.  So far so good.

When you hook up speakers to the Pioneer do not hook anything to the

“center” channel, just Front L/R and Surround L/R and Sub. Adjust the

settings on the Pioneer until it sees the DVD input (there’s a way to

tell it to find the digital input when you press the DVD button). Now

when you play a DVD you’ll have 4.1 from the Pioneer and quasi-center

from the TV. It’s not going to be perfect 5.1 or DTS but you may not

notice.

If it doesn’t sound right, I’m afraid you may have to move up a level

on the Pioneer to one with the pre-outs.

I think I understand what you're saying.  I may have a misconception,
though.  I thought analog output of the DVD and the Digital output
both had to be connected to the surround sound receiver.  When
receiving digital, doesn't the analog also have to be connected?
In other words, can you get audio out of the receiver with just
the digital connection with a digital signal?

Somehow I'm thinking you have to have both digital and analog
connected to hear audio.  

If I hear what you're implying is: for digital output audio from the
dvd, I don't need to have the analog cables connected to the
surround sound receiver to hear audio.  Is that right?

It may depend on your DVD player and how it handles the signal but

generally the digital and analog are not both required. Try it this

way. The worst that happens is we have to think of something else.

There are worse ways to spend an afternoon than tinkering with

electronic equipment (if you can't already tell, it's something I enjoy

doing.) Also, post the make/model of your DVD player for reference.

Re: TV Speaker for Center Front Surround




Your 953 has both digital and analog outs (they all do) and I'm pretty

sure they are both active when playing a DD/DTS encoded DVD. So try the

setup I described and see if it works to your satisfaction.  I'm

researching one more option but it may be a couple of days..

OK,

Cheers,


Re: TV Speaker for Center Front Surround




Another option and one that may sound better is to turn the center

channel off on the Pioneer. It will then route the center channel

signal to the front L/R. You do this by making the adjustment on the

setup menu on the receiver.

Try both ways and use the one that sounds best.

This is my current configuration.  I've the center channel turned off
via the receiver's internal menu.  It sounds good.  You can hear
the Gladiator's arrows whistle across the screen and horses pass
by like you're right there.

My nephew says if would be even better to have the center
front speaker.  He says it is the most important speaker in
5.1 digital.  So I thought I'd look into it.




Re: TV Speaker for Center Front Surround




Your nephew is correct. The center channel carries nearly all of the

dialog and a good portion of the overall sound.

The issue you'll likely face is the quality and tonal charistics of the

TV speakers and getting them to match the fronts. It may take some

tweeking of the TV volume and tone controls but have at it. It's not

going to do anything bad and it will give you a reason to play.

Re: TV Speaker for Center Front Surround


I'm amazed that the thing that I want to do is being talked about here,
the same day that I want to do it!

Anyway - I'm hoping to find a way to connect the center channel pre-outs
from my  Sony STR-D665 to the Audio In RCA ports on my Sony KV-27V42 TV
(in Video1 port). I have and S-Video cable coming from my Samsung DVD
Player (DVD-R120) going into the TV (in Video1 port), and the audio from
my DVD Player going into the audio in on my stereo receiver.

Is there no way to connect the raw (black/red) ports on my receiver's
center channel and send that mono signal to both the left and right (white
and red) speaker inputs on my TV?

Thanks - hope I gave enough info!!
Matt

Re: TV Speaker for Center Front Surround




Matt,

!!!!Do not connect the center channel speaker terminals (black and red

plastic either screws or spring loaded clips) to anything on your

TV!!!!

Did your Sony come with speakers? The only one that shows up on the

Sony web site is a HTIB system that does not appear to have preouts.

Are you sure you have the model number correct?

If your Sony does have pre-outs (it will have 6 of them Front-L/R,C,

Surround-L/R, and sub) try running the center pre-out (it will be only

one plug) to the L audio plug on the TV at video1. Then your speakers

get hooked up to the corresponding treminals on the receiver (unless

you have a separate amplifier the other pre-outs do not get hooked up).

That takes care of the surround. (How it sounds is another thing -

depends on your ears and listening habit. You may have to do a lot of

adjusting to balance the volume.)

Re: TV Speaker for Center Front Surround


OK - My receiver only has those spring loaded clips for all speaker
outputs - so is there no way to convert those two into one rca cable at
least? I wonder: while there's an input into the left speaker on my TV, if
there's a way to get the sound to come out both (in mono).

Re: TV Speaker for Center Front Surround




There is no way, that I know of, to convert your speaker level output to

one that would be acceptable for the TV.



On the DVD player there are analog audio outs (L/R - actually there are

two pairs). You can hook one of those pairs up to the audio in of the TV

(the same # input where you have the s-video cable). You should also run

a cable (either analog or optical either will work) from the digital out

of the Samsung to the digital in of the receiver. That is how you'll get

surround sound from the system.



Nice DVD player by the way...

Got to a car stereo store and tell them that you need a speaker level to rca
converter with a volume control built in wire both inputs of the unit
together and then hookup the unit to the TV...




Re: TV Speaker for Center Front Surround




Good idea - I hadn't thought of that solution...that's why there's more

than one of us on these forums....
