wiring tv and hi-fi to 1 set off speakers ??

as it says is this a good idea or bad

i have a jvc dolby pro logic tv
and
a technics stereo system

i am wanting to use my technics speakers at the rear of the room and put a switch box on the cable so that i can switch between using these as the surround sound speakers for the tv and the speakers for when listening to the stereo.

will this cause any major issues or is it as straight forward as it sounds ??

thanks for looking

I'm no expert but at the moment your hifi speakers are powered by the amplifier in your Technics system.... if you run a cable from your TV to the speakers, there will be nothing to power them. The output of the TV will not be enough to "drive" the speakers"

Has your hi-fi got an Externel, or Auxilliary input on the back? Most do. It will have RCA sockets (Red and White thingies). If your TV has the same RCA sockets on the back , you will just need a RCA cable to join them up.

That way, you'd just select Aux on your Stereo to listen to the TV sound through the hifi speakers.

This is the set up I had before I got my all-singing all-dancing Dolby Digital 5.1 system.

Good luck!

The jvc dolby pro-logic tv is already suround sound - it should have rear speakers of its own. Switching these for the hifi speakers wont work very well as the rear speakers on surround sound tv's only get a small level of volume, which would be a bit hopeless if put into bigger speakers.

Having a switch box might also have a negative effect on the other speakers. Might result in less volume going into the speakers.

the tv also has it's own amp i guess for the rear speakers .

my concern is that the loss is going to be quite large .

i never got speakers supplied as it was a insurance replacmeant and i have been using the ones from my original phillips tv . i am now re-decorating the living room and i am wanting to tidy things up by getting rid of one set .

cheers so far guys

Assuming that the rear outputs on the TV are power amplifier outputs and not low level signal outputs (aka line level signals) it should be easy enough to wire a switch to connect either a TV output or an amplifier output to each speaker.

If the TV outputs are low level signal jobs then do as the man says and connect to aux in on the amp.

The TV manual will say what you have. It can be difficult to tell by looking at the TV (unless it says "speaker" of course). If the connections are two spring loaded things per channel then you have speaker outputs, on the ther hand if you find RCA phono jacks (the round red/white ones) then you could have low powered speaker outputs or (more likely) low level signal outputs.

In either case it is quite safe to connect to connect the outputs to a speaker, if its a low level it just won't work. Don't connect speaker outputs to aux inputs though, that way lies grief. Obviously a speaker must be connected to only one amplifier at a time.

People have suggested that the TV amplifiers might be too low power to adequately feed the speakers, maybe so, but why not just try it?

As usual you try anything at your own risk!!!

it is deffo pro logic surround sound the connectors are spring loaded for a straight forward speaker connection

just that i dont want to loose any sound by connecting these both togeather via a source switch box like what maplin sell
