Presets
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.
This selects the subwoofer speaker for playing deep bass signals.
Set the method of playing the surround back channel for digital
signals.
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).
FM stations are received automatically and stored in the memory.

(6) 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 AVR-4802, 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.
