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
indicator is on:
The DISCRETE indicator lights up 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:
The DISCRETE indicator lights up 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 22).
• 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
indicator is on:
“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 22).
* 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, the DISCRETE indicator
does not light up in KARAOKE mode.
Customizing the Sound Fields
Each sound field is composed of a equalizer
parameters (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.
