It didnt take long to get back here!

The last step of my (in-laws) set up (5.1 wharfedale diamond pack) is to connect sky to the tv or receiver.

TV: toshiba 42hl800az
Receiver: Onkyo TX NR-515
old Sky satellite box (red, white, yellow connectors)

Originally I bought a toshlink optical cable but the tv, nor the satellite box had the correct terminal.

A friend at JB hi fi swapped the toshlink with 2 rca plugs-2 rca plugs.

My first question is should the sky box be connect to tv or receiver?

My second question is, will the 2x rca plug leads work ok.
And how should it be configured? tv->receiver, or sky->receiver

Another question is that the tv has a digital audio output (coaxial). Would this be a better option?
Im guessing it would have to be digital out of tv to digital in of receiver. With the sky to the tv?

 
Thanks

The first thing I'd do is get Sky to swap that old box for a silver Pace with SCART to Component cable.

I'm not sure if the 515 can route and output all sources out of the Main HDMI output (which would involve upscaling of composite/component sources). If it can't, then they are going to have to do some source switching on both the TV and the AVR.
In that scenario, there wouldn't be any advantage in connecting the cables directly to the AVR.

You could just connect them directly to the TV and then use a pair of RCAs from the TV's LR 'Monitor Out' to send back to the AVR (or single Coax if it works for more than just the internal tuner). The advantage of this would be that they could use the TVs speakers for the times when they don't want to use the AVR.

What sort of Tv is it.
I thought all modern TVs had optical digital out. Haven't seen one with co-ax out.
There are two types of optical connectors. Toslink with a flat on one side of the plu and also 3.5mm ones like the mini stereo plugs. Adaptors are available to convert one to the other and a lot of cables come with adaptor include. Sounds like you had the wrong connectors.
Definitely use optical out from the TV. The RCAs only give you stereo sound so you'll miss out on the surround decoding.
With moderm receiver you should connect external equipment to the recever via HDMI and then HDMI from receiver to TV.
I have an old Pace Sky box which connects to TV via Component (no HDMI), RCA audio to Receiver and Recorder and composite video to recorder. If your sky has HDMI out then connect to the receiver.

The onkyo 515 will up convert a 480i/576i component (or composite) to hdmi (multiple resolutions inc 4K). It won't up convert progressive or anything over that resolution.

In that case, I'd recommend connecting directly to the AVR and running a set of RCAs from the decoder to the TV for the times they only want to use the TV's speakers.

When they get that new sky box, they'll need that optical cable again.

Thanks for the replies.

I was surprised as well. The TV only has a Digital Audio output terminal, and a PC/HDMI Audio input, and usual L&R audio input/output terminals

The sky box only has an audio L&R, and is connected to tv by red, white & yellow connectors.

So the 2 rca plug leads I have will only play stereo, If I get a digital audio (coax) cable, would that decode to surround sound?

If so, then Im assuming the following set up is needed:

sky to receiver, then digital audio cable (coax) from tv to receiver?

Its pretty confusing

Nope. Forget anything digital with that current sky decoder. The Coaxial connection on the TV is for sending back audio from the internal (freeview) tuner. Its an output, not an input.

With a replacement Sky decoder, you can connect Component and Optical into the AVR.
Honestly, the sound quality isn't going to be much different, but that upgrade from Composite to Component is. Thats why its worth swapping the box (and Sky should do that without charge).

Just had a look at the manual and I see what you mean. Only one HDMI input and no optical out, only co-ax digital.
It's pretty basic. Connecting the co-ax digital out to the Receiver/Amp is the only way you're going to get surround sound.
Yes on the sky to receiver and co-ax digital tv to receiver.
I run my sky audio (2 x RCA) to the TV and the DVD Recorder. The sky box has two audio outputs (SCART sockets).
The TV doesn't appear to have ARC on the HDMI so most likely won't have passthrough from A/V or HDMI input to co-ax digital out either. On my Sony TV any audio input from any source (HDMI or RCA) will output via optical digital to the Receiver/Amp except on HDMI 4 input.
Sure is confusing til you get it sorted..

Thanks for the replies, I think its starting to make sense!

From what I have read (searching many other forums) is that the cable I now have (2 rca to 2 rca) will provide sound to all of the speakers but will not produce true surround sound!?

The coaxial digital audio cable from the tv to the receiver will decode / convert to surround sound?

Is that correct???


Youre not wrong about the confusing part!! Hopefully Im getting somewhere (thanks to everyone here)

Only for the TV's Freeview tuner.

ah ok thanks.

So there will be no point in getting a digital coax cable until they upgrade their sky box?

If they do that then they would need the above cable to get 5.1 surround sound? or not?

cheers

* An optical cable is required for the new Sky box to go directly into the AVR.

* A Digital coax cable is required to send back audio from the TV's freeview tuner and other analog sources that are connected to the TV (like say an old camcorder etc).

These are two different cables for two different purposes and they are not interchangeable.

Are they going to be watching Freeview aswell as Sky? If not, then I would keep things simple and not even bother with the TV's digital coax connection. Trying to get my folks/clients to understand the basics of switching between Sky and the internal tuner is a nightmare even without an AVR in the mix. I don't think you should go down that path unless you want to deal with the consequences.

Ah ok thanks for explaining it.

They will only be using it for sky.

So they will be getting 'stereo' by the front and rear speakers until they get a sky box with optical output.

I apologise for the basic questions

If they engage Dolby Prologic IIx on the AVR, then stereo sources will be mixed and distributed to the appropriate speakers, so they won't be stuck with 2.0 in the meantime.

I'm not sure what Sky offer in the way of DD 5.1 encoded programming, but they won't be able to take advantage of it until they get the new box.

If they are only using it for sky and not watching freeview on TV they won't be getting any surround sound unless they get MySkyHDi with HD ticket. I think they get Tv1,2,3 etc in HD and 5.1 for free (no HD ticket) on a MySkyHDi.
With the co-ax digital cable they can at least watch Freeview now with 5.1 sound on TV. If they are currently watching TV1,2,3 etc on sky they only get SD and Stereo. There's a big difference in quality.

B1GGLZ, although I don't disagree with anything you've just said, I think its important to point out that this for his inlaws. With all due respect to 33coupe, he is the best they've got. When it all turns pear-shaped and they switch to a blank input and can't find their way back again, he's the one who is going to have to sort it out. And probably over the phone.

Juggling Sky and Freeview is a basic task for us, but it doesn't make sense to everyone.
