Dolby Digital
Dolby Digital provides discrete multichannel
(up to a maximum of 5.1) audio. This is the same
audio system as is installed in movie theaters.
To enjoy Dolby Digital sound you need to con-
nect this unit's optical digital input to the digital
output on a DVD player with Dolby Digital
decoding capability.

Dolby Surround Pro Logic
When you play a 2-channel audio disc marked
Dolby Surround Pro Logic using an AV amplifier
equipped for Dolby Pro Logic, the audio is con-
verted into 4-channel audio.
Dolby Pro Logic gives enhanced spatial and
directional effects, creating theater-like sense of
presence and ambience.

DTS for Digital Theater Surround
DTS is a surround system delivering multi-chan-
nel audio from up to 6 independent sources. To
hear DTS discs, you need to connect the digital
output on DTS-capable DVD players and other
units to this unit's digital input.
Dynamic Range Control
Dolby Digital has a function for compressing
the difference between the loudest and softest
sounds: Dynamic Range Control. This control
ensures sounds with an increased dynamic
range are heard clearly even at low volume lev-
els.
Linear PCM (LPCM) /Pulse Code
Modulation
This is a recording technology used on music
CDs. Some DVD-Video discs also contain PCM
sound tracks. While music CDs are recorded at
44.1 kHz/16 bits, DVD-Video discs’ sound tracks
are recorded at 48 kHz/16 bits to 96 kHz/24 bits,
thereby offering better quality audio than music
CDs.
Optical Digital Input
By receiving optical digital input audio signals
in a digital signal format, the chance is mini-
mized that the sonic quality deteriorates in the
course of transmission. An optical digital input
is an input designed to receive digital signals
optically. (To take advantage of the digital input,
output units such as DVD players must have
optical outputs.)
