DOLBY SURROUND

Basic Operation

For 7.1 channel playback of 5.1 channel sources:

THX ULTRA2 CINEMA

You can only choose this mode if you have set up this amplifier for use with two surround back speakers (see pages 12, 26 & 38-40) and select 7.1 in LISTENING CH SELECT (see p.47).

When played using THX SURROUND EX, the surround sound field may actually sound narrower on some earlier Dolby Digital 5.1 and DTS 5.1 channel sources than with THX CINEMA processing. THX ULTRA2 CINEMA creates two extra channels from these sources and plays them through the surround back speakers.

With 5.1 channel sources, the THX ULTRA2 CINEMA mode is automatically selected when the LISTENING CH SELECT is set to AUTO (default).

THX MUSICMODE

You can only choose this mode if you have set up this amplifier for use with two surround back speakers (see pages 12, 26 & 38-40) and select 7.1 in LISTENING CH SELECT (see p.47).

THX MUSICMODE is for Dolby Digital 5.1 and DTS 5.1 channel sources that were not produced for a theatrical release—typically music. This mode creates two extra channels of natural, ambient sound and plays them through the surround back speakers.

ADVANCED CINEMA modes

The ADVANCED CINEMA mode is a newly designed system for enhancing movie soundtracks and other audio- visual sources that optimizes its effects in accordance with your source, LISTENING CH SELECT and speaker configuration. There are six ADVANCED CINEMA settings that use DSP (Digital Signal Processing) to create different types of sound environments.

ACTION

This mode is designed for action movies, which generally use lots of sound effects. The mode enriches the sound to make it more realistic and extends the parameters to pick up high and low sound effects.

SCI-FI

This mode is designed for science fiction movies. It creates a broad sound space, separating dialog from sound effects to heighten the overall impact of the soundtrack.

DRAMA

This mode is designed for movies with a lot of dialog. The elements of dialog are enhanced, making the characters seem more real. The mode also compresses the dynamic range somewhat so loud sounds do not overpower softer ones (compare this with the MIDNIGHT listening mode explained on p.54).

MUSICAL

This mode is primarily for music and adds a spacious feeling to the sound. A long delay time of reflected sounds provides resonant tones which emulate a concert hall.

MONOFILM

This mode is designed for older movies which are recorded with mono soundtracks. The special sound processing of this mode will allow you to experience these movies in surround sound even though they were not recorded that way originally.

X-D THEATER

This mode is especially designed to give sound depth to stereo sources. The overall effect builds a dynamic and broad sound space, allowing two-channel (stereo) signals to faithfully imitate a five speaker sound. The mode should be used in conjunction with Dolby Pro Logic for sources bearing the

mark.
