Using the Surround and THX Modes
This unit activates a variety of Surround and THX modes automatically. The stored basic settings and adjustments
performed on the Setup and Adjustment Menus (see pages 35 to 50) are applied.
• The following operations are only possible when the receiver is ready for Zone 1 operations, and are used only
for Zone 1 sources.
Reproducing Theater Ambience
In a movie theater, many speakers are located on the walls to
reproduce impressive multi-surround sounds, reaching you from all
directions.
With these many speakers, sound localization and sound movement
can be expressed.
Surround modes built in this receiver can create almost the same
surround sounds as you can feel in a real movie theater—with only
five or seven speakers (plus subwoofer).
Introducing the Surround and THX Modes
Home THX*
1
Home THX Audio Systems, developed by THX Ltd., has become
the world’s standard for film enjoyment in the home. It is one of the
multi-channel home entertainment systems to reproduce all multi-
channel sources accurately in the home.
In newly developed THX Ultra2 Cinema Mode or THX Music
Mode, all multi-channel software (5.1 channels or more) is
automatically detected and proper processing is applied to improve
directional and ambient surround information through four surround
speakers—two at the side and two at the back.
• This receiver provides four types of THX modes—THX Ultra2
Cinema (THX U2 CINEMA), THX Music (THX MUSIC), THX
Surround EX (THX SURR EX), THX Cinema (THX CINEMA).
When any one of the THX modes is activated, the
indicator
lights up on the display.
THX Ultra2 Cinema : Best for playing any 5.1-channel encoded
movie software, this mode can stabilize the
sound localization and enlarge the sound
field. (Only selectable with a pair of
surround back speakers.)
THX Music : Best for playing any 5.1-channel encoded
music software. (Only selectable with a
pair of surround back speakers.)
THX Surround EX : Best for playing Dolby Digital EX encoded
software. (Only selectable with one or a
pair of surround back speakers.)
THX Cinema : To reproduce the sound through all
activated speakers except surround back
speakers. (When THX Cinema is applied to
Neo: 6 Cinema, sounds can also be emitted
from the surround back speakers.)
• THX modes can be also applied to any source together with
another Surround mode.
Dolby Digital*
2
Dolby Digital is a digital signal compression method, developed by
Dolby Laboratories, and enables multi-channel encoding and
decoding (1ch up to 5.1ch).
• When a Dolby Digital signal is detected through the digital input,
the
DIGITAL
indicator lights up on the display.
Dolby Digital 5.1CH
Dolby Digital 5.1CH (DOLBY DIGITAL) encoding method
records and digitally compresses the left front channel, right front
channel, center channel, left surround channel, right surround
channel, and LFE channel signals (total 6 channels, but the LFE
channel is counted as 0.1 channel. Therefore, called 5.1 channel).
Dolby Digital enables stereo surround sounds, and sets the cutoff
frequency of the surround treble at 20 kHz, compared to 7 kHz for
Dolby Pro Logic. As such, the sound movement and “being-there”
feeling are enhanced much more than Dolby Pro Logic.
Note:
When the ZONE 2 speaker indicator is lit on the display, you
cannot use the THX modes and Surround modes requiring the
surround back speakers.
– You can only use those modes which do not require the
surround back speakers.
