If you recently got a DVD player you might be wondering what all those connectors on the back are for. Don't worry, you don't have to use them all, a lot of the connectors are redundant. In general, you will need to pick one type of video connection, and one type of audio connection for your system. We'll go through what each type of connector is for, and show you how to pick the best ones to use.
- Coaxial Digital Output and Optical Digital Output
These outputs provide the highest quality audio. They send six channels of digital sound information (for six separate speakers: front left, front center, front right, rear left, rear right, and subwoofer) to the receiver for decoding. You can use either one of these outputs if you have a Dolby Digital receiver.
This player has one coaxial and one optical digital output.

- 5.1 Channel Outputs
5.1 channel is a set of six analog outputs, one for each of the Dolby Digital channels (left front, center front, right front, left rear, right rear and subwoofer). The DVD player decodes the Dolby Digital signal and uses its own digital to analog converter (DAC) to output an analog signal. These are the outputs you'll need to use if you are hooking the DVD player up to a "Dolby Digital ready" receiver.
DVD players with 5.1 channel outputs will always have Dolby Digital decoders, and they may or may not have DTS (digital theater sound) decoders. If you have a "Dolby Digital ready" receiver and you want DTs sound, you will need a DVD player with a built-in DTs decoder.
This player has one set of 5.1 outputs.
- Stereo Outputs
These outputs carry only the stereo music signal. You would use these if you were hooking your DVD player up to a TV that has only two speakers, or to an older stereo (two-channel) receiver.
This player has two sets of stereo outputs.
