Digital to provide a wide stable rear soundstage.
Advanced Speaker Array
ASA processing offers maximum effect when two surround back speakers are used and the speakers are
placed near each other. This technology is used for Ultra2 Cinema, THX Music MODE and THX Surround EX.
Boundary Gain Compensation
When using a THX Ultra2 compatible subwoofer or a subwoofer with ultra-low frequency playback
capabilities (with a frequency response extending to approximately 20 Hz), the low frequency band may rise
and the sound may seem booming. This technology compensates the gain and makes the audible level flat.

THX Surround EX
In 1999, a new surround system was launched simultaneously with the release of the movie “Star Wars
Episode I”. “Dolby Digital Surround EX” is a new movie sound track that greatly enhances the sense of
spatial expression and the positioning of the surround channel sound. The result is 360 degrees of
movement and moving sound effects that seem to pass right over the listener's head.
This system was developed jointly by Lucasfilm THX and Dolby Laboratories, fusing Lucasfilm's idea of
improving spatial expression and achieving a uniform 360 degree sound positioning with Dolby Laboratories'
matrix encoding technology. Emphasis was placed on compatibility with the existing system Dolby Digital
5.1-channel, and the new "surround back (SB) channel" was added to achieve improvements over the
conventional 5.1-channel system in terms of the positioning of the sound at the rear, the acoustic image of
sound moving from the two sides to the back as well as sound moving from the front to the center rear with
the multi surround speaker systems used in movie theaters, thereby enabling various types of surround
sound.
The surround back channel signal is a matrix-encoded signal inserted into both the Dolby Digital SL (surround
left) and SR (surround right) channels. Upon playback, the signals are decoded by a high precision digital
matrix decoder within the Dolby Digital decoder into the SL, SR and SB channels and output as 6.1 channels
of signals. With the AVC-A1SR, the signals further undergo Home THX Cinema processing to achieve a THX
Surround EX system.
Even without the proper environment for playing the SB channel, Dolby Digital Surround EX signals are 100%
compatible with existing 5.1-channel playback systems, so they can be played as such. In this case, the SB
channel signal is produced as a monaural signal from both the SL and SR channels, so none of the signal
components are missing. The effects specific to THX Surround EX (the sense of spatial expression and the
positioning of the sound), however, are the same as with conventional 5.1-channel surround systems.

Input the combination of speakers in your
system and their corresponding sizes (Small for
regular speakers, Large for full-size, full-range) to
automatically set the composition of the signals
output from the speakers and the frequency
response.
Use this function when using multiple
surround speaker combinations for more
ideal surround sound. Once the
combinations of surround speakers to
be used for the different surround
modes are preset, the surround
speakers are selected automatically
according to the surround mode.
Set the frequency (Hz) below which the bass sound
of the various speakers is to be output from the
subwoofer.
Set whether or not to lock the system setup
settings so that they cannot be changed.
This adjusts the volume of the signals output from
the speakers and subwoofer for the different
channels in order to obtain optimum effects.
This parameter is for detecting the maximum level
of the low bass signals output from the subwoofer
channel in order to protect the subwoofer from
damage and prevent unpleasant distorted sounds
from being produced.
This assigns the digital input jacks for the
different input sources.
This sets whether or not to display the on-screen
display that appears on the monitor screen when
the controls on the remote control unit or main unit
are operated (from MONITOR 1 outputs only).
