Digital Audio Connections

Optical Digital Audio Connection Notes

•Remove the dust protection cap from the optical digital audio output and connect the cable firmly so that the configurations of both the cable and the connector match.

•Keep the dust protection cap and always reattach the cap when not using the connector.

For Your Reference:

•Dolby Digital is a digital sound compression technique developed by the Dolby Laboratories Licensing Corporation. Supporting 5.1-channel surround sound, as well as stereo (2-channel) sound, this technique enables a large quantity of sound data to be efficiently recorded on a disc.

•Linear PCM is a signal recording format used in CDs. While CDs are recorded in 44.1kHz/16-bit, DVDs are recorded in 48kHz/16-bit up to 96kHz/ 24-bit.

•If you have a Dolby Pro Logic Surround decoder connected to the DVD 25’s analog audio out con- nectors, thanks to the “Downmix” function of the DVD 25 you will obtain the full benefit of Pro Logic from the same DVD movies that provide full 5.1- channel Dolby Digital soundtracks, as well as from titles encoded with Dolby Surround.

•The DVD 25 is designed to digitally output 96kHz PCM audio with a 96kHz sampling rate. The 96kHz indicator will light in the display. However, some 96kHz DVDs may include copy protection codes that do not permit digital output. For full 96kHz fidelity from these discs, use the analog outputs of the DVD 25. If your surround processor converter does not support 96kHz PCM audio, you must use the DVD 25 analog outputs for full 96kHz fidelity with these discs.

•When connecting an amplifier (with an optical/ coaxial digital input) that does not contain a Dolby Digital or DTS decoder, be sure to select PCM as the initial setting in the Digital Output menu (see page 18). Otherwise, any attempt to play DVDs may cause such a high level of noise

that it may be harmful to your ears and damage your speakers.

•CDs can be played as they would normally be played.

NOTE: Some first-generation DTS decoders that do not support DVD-DTS interface may not work properly with the DVD/CD player.

Dolby Digital and DTS

Both Dolby Digital and DTS are audio formats used to record 5.1-channel audio signals onto the digital track of film. Both of these formats provide six separate channels: left, right, center, left rear, right rear, and common subwoofer.

Remember that Dolby Digital or DTS will only play

5.1-channel sound if you’ve connected the optical or coaxial output of the DVD 25 to a DTS or Dolby Digital receiver or decoder (see page 13) and if the disc was recorded in the Dolby Digital or DTS format.
