Sound Adjustment
Relationship between a Dolby-surround-sound-
encoded source and sound output from the
amplifier
Sound output from the amplifier for a Dolby-surround-
sound-encoded source will differ according to the
contents of the sound source and the settings on the
amplifier, as described below.
• For a sound source consisting of Discrete data
When the DOLBY NORMAL SURROUND or ENHANCED
SURROUND sound field is selected or the DIRECT PASS button
lights up:
“DISCRETE” appears in the display and the sound is
decoded and output as is for all Dolby Digital sound
channels in the source.
When a sound field other than ACOUSTIC and KARAOKE* is
selected:
“DISCRETE” appears in the display and all Dolby Digital
sound channels in the source are processed with the sound
field before being output.
When the ACOUSTIC sound field is selected or the sound field
is turned off:
The sound source is downmixed to 2 channels (L/R
stereo) and output. When the ACOUSTIC sound field is
selected, you can adjust the equalizer parameters (see
page 21).
• For a sound source with Dolby Pro Logic data
When the DOLBY NORMAL SURROUND or ENHANCED
SURROUND sound field is selected or the DIRECT PASS button
lights up:
“PRO LOGIC” appears and the Dolby Pro Logic sound is
decoded and output.
When a sound field other than ACOUSTIC is selected:
The sound source is processed with the sound field before
being output. If the sound field genre is MOVIE
(excluding MONO MOVIE sound field) or 3D, “PRO
LOGIC” appears in the display and Dolby Pro Logic
sound is decoded and output.
When the ACOUSTIC sound field is selected or the sound field
is turned off:
The sound source is downmixed to 2 channels (L/R
stereo) and output. When the ACOUSTIC sound field is
selected, you can adjust the equalizer parameters (see
page 21).
* The KARAOKE sound field reduces the level of the vocal
component which is located at the center of 2-channel
stereo sound. Since this sound field downmixes a 5-
channel Dolby Digital source to two channels and
processes it in the same way, “DISCRETE” does not
appear in KARAOKE mode.
Customizing the Sound Fields
Each sound field is composed of a tone parameter
(bass/treble) and surround sound parameters —
variables of sound that create the sound image. You
can customize the sound fields by adjusting some of
the sound parameters to suit your listening situation.
Also, since this amplifier uses Digital Signal Processing
(DSP), you can adjust the sound parameters
electronically. DSP automatically converts analog
audio signals to digital, which lets you adjust the
sound with virtually no degradation in sound quality.
Once you customize the sound fields, they are stored in
memory unless the amplifier is unplugged for about 1
week. To change a customized sound field, make new
adjustments to the sound field.
