Blu Ray player inputs/outputs - 25/1/2013 3:08:16 PM

Guys, have spied a cheap Blu Ray player, and wondering if my current 5.1 system will work on it. My current system came along with the DVD player, and the speakers are all connected to the DVD player with wires inserted into the back of the DVD player. Will I be able to do this with the Blu Ray player, or will I require a new surround sound system. I'm unaware of what connections are round the back of a Blu Ray player (never looked at the back of one) and unaware of how to connect surround systems up-the current one was my first, and like I said, that attaches up simply to the DVD player. Please help, would like to be able to make the leap up to Blu Ray!

If it's a stand alone Blu-Ray player then no, you won't be able to plug all the speakers into it.

Your DVD player is most likely an All-In-One solution, which means it contains amplification (for the speakers) amongst other things.

What you might be able to do is plug the Blu-Ray into the DVD All-In-One combo unit via optical or coaxial leads and use it that way, for sound only. You'll have to see if your DVD All-In-One unit has inputs (not outputs) on the back for such things, it might not even support external inputs, but it's worth a look.

Hope this helps.

This is exactly my setup - we have a DVD/HDD combo with surround sound and the Blu Ray plugs into it via the old red/white cables.

I currently use a PS3 for Blu Ray movies, which lets me output the sound through our older DVD player speaker combo setup through the standard red-white leads easily enough. Does your player have those ports on the back? It's never going to get any kind of HD sound upgrade but it works enough for me.

Edit: as UTB said while I was still typing. So sounds like a plan right.

I hate to be the bearer of bad news guys (Rich and UTB) but both your setups are not providing you with surround sound, they're just giving you stereo sound (the same standard audio you'd get if you just watched through your TVs).

When you use the red and white RCA cables, you're limiting yourself to analogue sound tracks rather than the digital surround sound tracks from the discs you are watching. The reason there is two cables in your setup is simply because you are wiring up two channels of audio, a right and a left speaker, where as with surround sound there are numerous channels one for each speaker and subwoofer. In most home cinema cases there should be 6 channels, front left, right and centre, rear left and right, and your subwoofer.

Any sound you guys are getting from your extra speakers and subwoofer are emulated, i.e. it's just sound copied from the left and right rather than directional sound/sound specifically intended for an individual speaker or speakers.

My advice would be to check as Paulyboy says if your DVD player has an optical or coaxial input port on the back and your Blu Ray player has a matching output, there's every chance that both could have the required optical port, coaxial less so.

You'll then need to go into the settings of your Blu Ray player/PS3 and ensure surround sound is switched on and is outputting via the optical port rather than via HDMI or any analogue means of output.

No worries I thought that would be the case.

Still sounds awesome though

So how do they get away selling these types of quick cinema setups that have all the speakers if the sound isn't really 5.1? Bastards. To be honest I have never noticed it being simply stereo and its worked that way since the days of the old Rogue Squadron speaker test on my first and cheapest version of these things back in the day.

Here's a question then.. I have a 2.1 system (L/R and a woofer) - does that mean I'm still getting the best I would out of it?

It will have been surround sound for the built in DVD player, but for any connected source urns only going to be surround sound if it has the correct inputs, anything else such as your red and white RCA connections won't be surround sound. Just see if you've got an optical in port on the back of the player, if so you can connect it to your Blu ray player to get surround sound once again.

Sadly not as it is an RCA connection so there's nothing specific for your your subwoofer, where as if it was HDMI/Optical/Coaxial you'd get to use a digital sound track such as Dolby Digital or Pro-Logic which include specific subwoofer sounds. However if your TV speakers aren't up to much at least you'll have an improvement and the subwoofer will add some bass to any lower tones.

As I said to rick, just check if the DVD player has an optical input on the back, if it does you can buy a cheap optical cable and take advantage if the better soundtrack and audio quality by hooking up your Blu ray player this way.

Cheers - there is an optical input on the back of both so I'll hook that up :)

That isn't necessarily entirely accurate.

When a Blu-ray (or DVD) player downmixes the multi-channel sound to 2 channel stereo it can usually encode extra surround information into those tracks. If a suitable decoder receives this information it can extract surround channels from the 2 tracks. The most common form would involve 4 channel surround matrixed into a 2 channel track; this was commonly used on video tapes under the trademark "Dolby Pro Logic". This was a domestic version of the "Dolby Stereo"system used in cinemas.

It gives a 4 channel surround sound: 3 front channels and 1 mono surround channel, which while not as good as a true discrete surround track is better than no surround at all. There are also more advanced forms of Pro Logic offering 5 or more channels from a 2 channel track.

Assuming your player adds this information to the 2 channel stereo (it may have to be switched on in the menu), and your DVD player/surround system can decode it you will be getting a form of surround sound, albeit a somewhat less precise version.

Further to SHP's excellent response, all speaker/subwoofer packages (in fact any speaker with more than one driver) will have a crossover. This is a filter which sends certain frequencies to the subwoofer and the rest to the speakers. It allows small speakers to provide a fuller, deeper sound than they could by themselves.

As a 2.1 system won't get the benefit of a full multi channel surround track the phono cables should be just fine. You might see an improvement if the DAC (digital to analogue converter) in the speaker system is better than the DAC in the player. But that will be an increase in fidelity rather than anything else and is in no way assured.

Valid points Dpp, it's been a while since I was very much into the while A/V scene, so probably not as in depth a response as I should have given.

However it is worth noting that whilst what you say about the 2.1 setup is correct you would still be limited to an analogue signal and there's definitely an argument to be had that using a digital signal from an optical cable would provide you with a better audio experience.

Besides all that, what bluray player? http://www.richersounds.com/ have often got good deals on, a friend got a Bluray all-in-one for 130 (LG one) and it's really good!

That depends entirely which component has the best DAC. If it is the player you're better off letting the player decode and using analogue cables. If it is the 2.1 system you might be better off sending a digital signal and decoding there.

Unless we are talking about mid range to high end gear I doubt the difference would be very noticeable.
