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 ModesHome 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 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.

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.

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.
