Digital Audio Playback
Digital audio is a major advancement over older analog surround processing systems such as Dolby Pro Logic. It delivers five or six discrete channels: left front, center, right front, left surround and right surround and with DTS ES (see below) even surround back (with identical signals for left and right). Each channel repro- duces full frequency range (20Hz to 20kHz) and offers dramatically improved dynamic range and significant improvements to

Note that an optional, external RF demodulator is required to use the AVR to listen to the Dolby Digital sound tracks available on laser discs.
Connect the RF output of the LD player to the demodulator and then connect the digital output of the demodulator to the Optical or Coaxial inputs *Ó of the AVR. No demodulator is required for use with DVD players or DTS- encoded laser discs.
DTS
DTS is another digital audio system that is capa- ble of delivering 5.1, 6.1 or 7.1 audio. Although both DTS and Dolby Digital are digital, they use different methods of encoding the signals, and thus they require different decoding circuits to convert the digital signals back to analog.
rear panel | or front panel *Ó. |
In order to listen to DVDs encoded with DTS sound tracks, the DVD player must be compatible with the DTS signal as indicated by a DTS logo on the player’s front panel. Note that early DVD players may not be able to play DTS- encoded DVDs. This does not indicate a problem with the AVR, as some players cannot pass the DTS signal through to the digital outputs. If you are in doubt as to the capability of your DVD player to handle DTS DVDs, consult the player’s owner’s manual.
Please note that some DVD players are shipped with their output set for Dolby Digital only. To insure that DTS data is being sent to the AVR, please check the setup menu system on your DVD player to make certain that DTS data output is enabled.
PCM Audio Playback
PCM (Pulse Code Modulation) is the non- com- pressed digital audio system used for compact discs,
Connections may be made to either the Optical
or Coaxial inputs on the rear panel or the front panel Digital Inputs *Ó.
To listen to a PCM digital source, first select the input for the desired source (e.g., CD) to feed its video signal (if any) to the TV monitor and to provide its analog audio signal for recording. Next press the Digital Select button ÛG and then use the ⁄/ ¤ buttons Eon the remote, or the Selector buttons 7$ on the front panel, until the desired choice appears in the Lower Display Line ˜, then press the Set button @Fto confirm the choice.
In most cases this will be 48 KHZ, though in the case of specially mastered,
The PCM 48 KHZ indication will also appear when modes or inputs are changed for analog sources. In those cases the system is telling you the sampling frequency used internally at the output of the
During PCM playback the unit automatically will turn to the default surround mode or to the LOGIC 7 mode but you also may select any surround mode except Dolby Digital or DTS.
