DIGITAL AUDIO CONNECTION Optical Digital Audio Connection Notes Gently push the cable plug through the built-in shutter that covers the Optical Digital Audio Output 3, and connect the cable firmly so that the configurations of both the cable and the connector match. Audio Output From the Unit's Optical/ Coaxial Digital Audio Output Connector Disc: Sound recording Optical/coaxial digital format: audio output: DVD Dolby Digital Dolby Digital bitstream (2-5.1ch) or PCM (2ch, 48kHz, 16-bit)† Linear PCM (48/96kHz, 16/20/24-bit) Linear PCM (2ch) (48/96kHz, 16/20/24-bit) DTS Bitstream or no output† MPEG (2.0) MPEG bitstream (2ch) or linear PCM (2ch, 48kHz) VCD MPEG-1 CD-DA Linear PCM† CD Linear PCM MP3 (MPEG-1 Audio Layer 3) DVDAudio, SACD WMA (Windows Media Audio) Linear PCM (44.1kHz sampling) Linear PCM (44.1- 48kHz, depending on source, if digital output format selected as "Bitstream"). (48kHz if digital output format selected as "PCM") Linear PCM (32-48kHz) No digital audio output available † Digital format must be selected as "Bitstream" or "PCM" in Digital Output menu (see "Digital Output" section on page 21). For Your Reference: • Dolby Digital is a digital sound compression technique developed by the Dolby Laboratories Licensing Corporation. Supporting 5.1- or 6.1channel surround sound depending on the specific disc, as well as stereo (2-channel) sound, this technique enables a large quantity of sound data to be efficiently recorded on a disc. • DTS is another digital audio technology developed by Digital Theater Systems, Inc. It supports 5.1 and 6.1 surround sound, depending on the specific disc, thanks to a sophisticated encoding system. Some receivers and processors also feature Dolby Pro Logic IIx and DTS Neo:6® matrix postprocessing decoders that may be used with DTS 5.1 discs to derive the surround back channel. • 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 47's analog audio out connectors, thanks to the "Downmix" function of the DVD 47 you will obtain the full benefit of Pro Logic from the same DVD movies that provide full 5.1channel Dolby Digital soundtracks, as well as from titles encoded with Dolby Surround. • The DVD 47 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 47. If your surround processor converter does not support 96kHz PCM audio, you must use the DVD 47 analog outputs for full 96kHz fidelity with these discs. • When connecting a receiver or surround processor with a 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 21). 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 in a conventional CD player. • Dolby Digital, DTS and PCM signals are passed through the HDMI Output 2. However, DVD-Audio and SACD signals are not carried via the HDMI connection. You must connect the 6-Channel Audio Outputs 9 to the corresponding input jacks on your receiver or processor in order to enjoy DVD-Audio and SACD materials. 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 surround, right surround and LFE (low-frequency effects). The latest discs may include the 6.1-channel formats, such as Dolby Digital EX and DTS-ES® Discrete or Matrix. These formats add an additional surround back channel behind the listener to create an even more realistic sense of envelopment. 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 47 to a DTS or Dolby Digital receiver or decoder (see page 16) and if the disc was recorded in the Dolby Digital or DTS format. NOTE: Some first-generation DTS decoders that do not support DVD-DTS interface may not work properly with the DVD/CD player. DVD-Audio and SACD The high-resolution output of DVD-Audio and SACD discs is only available as an analog signal. For that reason, it is necessary to make direct analog connections between the 6-Channel Audio Outputs 9 on the DVD 47 and the matching 6-channel inputs on your receiver or surround processor. 18 DIGITAL AUDIO CONNECTION
