RCA Surround Sound Connections
|

What does the connector on the device look like?
RCA surround sound connectors on the back of your device look like this.
There are six RCA jacks for each of the 5.1 surround sound connections.
Front left/right, centre, surround left/right and subwoofer.
On some devices you may find more connections than this, and this would be for 6.1/7.1 configurations.
What does the cable look like?
You don't really need a special cable for connecting to a device with an analog multichannel output. You just use standard analog RCA to RCA cables.
For instance, you could use three cables with a stereo RCA plug to make the connections - or six individual ones.
Just make sure you connect the same jacks together - front right to front right, centre to centre, front left to front left etc.
What does it do?
It is used for transmitting multichannel analog audio signals. It does not support digital audio signals.
When should I use it?
In most cases, if you wanted to send multichannel audio to an AV receiver or amplifier, you would use the digital audio connections such as an HDMI connector, optical digital audio or coaxial digital audio.
However, it may be that your DVD/Blu-ray or your amplifier doesn't have any digital audio connections. In this case, you could still hear surround sound in your room if your player and amplifier both had analog multichannel jacks.
Also, in some circumstances, you may need to use analog multichannel outputs from a DVD/Blu-ray player in order to hear some types of multichannel audio such as SACD, Dolby TrueHD and DTS-HD Master Audio.
What else can you tell me?
With more devices having digital audio connections, it is becoming less common to find audio-visual components with an analog multichannel output.
However, the presence of this type of connection can lengthen the lifespan of older devices by removing the reliance on digital connections.
Whilst a digital audio connection has many good things going for it, the copy-protection that is present in some of these digital audio signals isn't one of them! Which is where analog multichannel devices can come into their own.
As long as your DVD/Blu-ray player can decode the digital audio on-board, you can then hear this audio from the analog outputs without worrying about having a compatible digital amplifier. This can enable you to hear SACD, DVD-A, DTS-HD Master Audio and Dolby TrueHD soundtracks without spending extra money upgrading all your equipment.
