Dolby encoded. It will use DTS Neural:X to send
audio to all congured speakers if a DTS encoded
audio stream comes in. If a 2 channel or multi-
channel PCM stream comes in, it will use Dolby
Surround to send audio to all congured speakers.
Dolby Surround will invoke Dolby’s post
processor to always send audio to every congured
loudspeaker no matter the input stream type.
DTS Neural:X will invoke DTS’ post processor to
always send audio to every congured loudspeaker
no matter the input stream type.
Multi-Channel Stereo will downmix and/or upmix
to send audio to all Left and Right oor speakers
(plus sub if congured) no matter the input stream
type.
Stereo will downmix to send audio to only the Left
and Right front speakers (plus sub if congured) no
matter the input stream type.
Through will neither upmix or downmix. The input
stream will be sent to the congured speakers per
the input le stream with no post processing.
In the Trim Menu (see “The Trim Menu” on page
27), the current input can be assigned to:
• Music
• Movie
• Game
• Auto
• Through
The Surround Mode represented by the Trim
selections Music, Movie and Game must be
assigned in Setup. If no assignment has been made,
the Default for each is Auto.
Audyssey
In the Audio Setup menu, three Audyssey setting
can be adjusted:
• MultEQ
• Dynamic Volume
• Dynamic EQ Offset
MultEQ XT32 optimizes the frequency response
of your speakers. It compensates for both time and
frequency characteristics of the listening area based
on Audyssey
®
Setup.
MultEQ menu options:
• Reference
• Flat
The default setting is Reference. Reference provides
a compensation curve that is optimized for movies
with a slight roll off at the higher frequencies. With
the volume set for 0dB (63%), you will be hearing
the mix at the same level the mixers heard it.
The Flat setting is optimized for small rooms where
your listening position is closer to the speakers.
Keep in mind that many movie soundtracks are
optimized for large theaters. The options in the
Audyssey
®
setup section help maintain the theater
experience in smaller spaces as well as at lower
volumes. The Flat setting utilizes the Audyssey
room correction curves without the additional
compensations for movie mixing.
Dynamic EQ solves the problem of deteriorating
sound quality as volume is decreased by taking
into account human perception and room acoustics.
Dynamic EQ can be turned On and Off in the Trim
Menu (see “The Trim Menu” on page 27). If it is
On (the default), the Reference Level Offset option
appears. Audyssey
®
Dynamic EQ
®
is referenced to
the standard lm mix level. It makes adjustments
to maintain the reference response and surround
envelopment when the volume is turned down from
0dB. However, lm reference level is not always
used in music or other non-lm content. Dynamic
EQ Reference Level Offset provides three offsets
from the lm level reference (0dB, 10dB, and
15dB) that can be selected when the mix level of the
content is not within the standard.
