Input Setup
Input source signals
a. Analog/PCM
Analog sources consist of LP records, AM and FM
broadcasts, cassette tapes, and the such. PCM (Pulse
Code Modulation) is one form of digital audio signals
and is recorded directly onto compact discs and DVDs
without compression.
b. PCM fs > 48 k
Digital PCM sources that are recorded at a sampling
rate of greater than 48 kilohertz. This includes compact
discs and DVDs that are recorded with high quality au-
dio.
c. PCM fs = 192 k
Digital PCM sources that are recorded at a sampling
rate of greater than 192 kilohertz. This includes com-
pact discs and DVDs that are recorded with extremely
high quality audio.
d. Dolby D (Dolby Digital)
Digital data with AC-3 compression and a maximum of
5.1-channel surround sound. This source signal comes
from DVDs and LDs that have the
mark and there-
fore recorded for 5.1-channel output. This source also
comes from digital satellite broadcasts that support
Dolby Digital.
Dial norm
Dialogue Normalization (Dial Norm) is feature of
Dolby Digital. When playing back software that has
been encoded in Dolby Digital, sometimes you may
see a brief message in the front panel display that
read Dial Norm xdB (“x” being a numeric value).
Dialogue Normalization serves to let you know if the
source material has been recorded at a higher or
lower level than usual. For example, if you see the
message “Dial Norm: +4” in the front panel display,
to keep the overall output level constant just turn
down the volume control by 4dB. In other words, the
source material that you are listening to has been
recorded 4dB louder than usual. If you do not see a
message, then no adjustment of the volume control
is necessary.
e. DTS
DTS (Digital Theater System) is compressed digital
data with a maximum 5.1-channel surround output
that allows for an extremely high-quality sound. This
source signal requires a DVD player that supports DTS
output and comes from compact discs, DVDs, and
LDs that have the
mark.
f. MPEG
Digital data with a maximum of 5.1-channel sur-
round audio with MPEG compression. This source sig-
nal comes from DVDs that have the
mark.
g. D.F. 2 ch
This corresponds to 2-channel digital format sources.
This signal source comes from LDs, DVDs, and other
digital sources that are recorded with 2-channel au-
dio.
h. D.F. Mono
This corresponds to monaural digital format sources.
This signal source comes from LDs, DVDs, and other
digital sources that are recorded with monaural au-
dio.
Listening Modes
Mono
This mode is for listening to the left and right channels
separately. This mode also allows you to listen to the
multiplexed soundtracks on DVDs, and other media
that have them.
Stereo
This mode has all input sound is output from the left and
right front speakers.
Direct
This mode delivers pure sound with minimum sound
quality adjustment and filtration. The sound recorded
for the right and left front channels is output to the right
and left front speakers only and not output to the
subwoofer.
Dolby D (Dolby Digital)
This mode is for listening to sources encoded with Dolby
Digital in their plain format.
DTS
This mode is for listening to music DTS sources in their
plain format.
DTS Film
This mode is for listening to cinema DTS sources in their
plain format.
MPEG
This mode is for listening to music MPEG sources in their
plain format.
MPEG Film
This mode is for listening to cinema MPEG sources in
their plain format.
THX (THX Cinema)
Movies that have been encoded in Dolby Digital, DTS,
MPEG, and Dolby Pro Logic can all benefit by activat-
ing the THX mode. THX should be activated only when
watching movies that were mixed for playback in large
movie theater environments. THX need not be acti-
vated for music, for movies that were made especially
for television, or for shows such as sports programming,
talk shows, and the like. This is because they were
mixed in a small room environment.
For best results, use a THX certified speaker system.
• How to enjoy THX Surround EX
When the THX listening mode is selected, you can
press the THX button on the remote controller to
cycle through the settings “Auto,” “On,” and “Off.”
When “Auto” is selected, if a Surround EX encoded
source is input, it is automatically played in the THX
Surround EX mode. When “On” is selected, all sur-
round EX encoded sources and THX Surround EX
playable sources (i.e., DTS-ES encoded sources) are
played in the THX Surround EX mode. If the sound
does not feel correct, set this to “Off.”
If “On” is selected and a source that cannot be
played in the THX Surround EX mode, “THXCinema”
appears in the front display. If “Off” is selected, the
listening mode becomes THX Cinema.
