Dolby Pro Logic II: Dolby Pro Logic II decoding is designed to produce a 5-channel output from

two channel source material.

There are two different modes available in Pro Logic II: ‘Movie’ and ‘Music’ modes, which are

intended for use as their names suggest. Due to the different recording methods used for movies

and music, it is recommended that the correct decoding mode for your source material is used

to obtain the best results.

Movie Mode: This is intended for use with ‘cinematic’ material, which is mixed and monitored in

a calibrated multi-channel environment. Movie mode is a ‘xed’ mode that is designed to give a

similar sound when listening using a home cinema system to that obtained in a cinema.

Music Mode: Stereo music is not designed for surround processing, although good surround

effects can be obtained through careful production. As the optimum decoding method varies

according to the recording, Music mode allows user adjustment of the processing characteristics.

Information about adjusting the Music mode by using ‘Dimension’ and ‘Centre Width’ controls

can be found in the ‘Main Menu Screen 2’ section.

Dolby Pro Logic IIx: Dolby Pro Logic IIx is an extension of the Dolby Pro Logic II matrix-decoding

method. The decoder allows the processor to derive seven outputs from a two or multi-channel

(up to 5.1 with EX) source to take better advantage of all ampliers and speakers in a 7.1 setup.

There are two different modes available in Pro Logic IIx: Movie and Music modes. Due to the

different recording methods used for movies and music, you should select the correct decoding

mode for your source material.

Dolby Pro Logic Emulation: Dolby Pro Logic decoding is a legacy mode that is designed to produce

a ve-channel output from two-channel source material. It should be used only when the

source material is encoded as Dolby Pro Logic; otherwise, we recommend the use of Dolby Pro

Logic II. This is because Pro Logic processing on straight stereo sources can sound mufed and

compressed.

DTS NEO:6: DTS Neo:6 provides up to six full-band channels of decoding from stereo material. The

AV9 will derive separate channels corresponding to the standard home theatre speaker layout.

Cinema: A movie mode designed to reproduce a movie theatre environment. Neo:6 technology

allows various sound elements within a channel or channels to be steered separately, and in a

way which follows the original presentation naturally.

Music: A music mode designed to produce a lively, high-integrity surround-effect from most two-

channel music sources from all available speakers. Neo:6 music mode expands stereo recordings

into the ve- or six-channel layout without diminishing the subtlety and integrity of the original

stereo recording.

Multi-channel source modes

Digital multi-channel source material is normally provided as ‘5.1 audio’. The ‘5.1 channels’ comprise of:

left, centre and right front speakers, two surround speakers and a low frequency effects (LFE) channel.

Since the LFE channel is not a full range channel, it is referred to as ‘.1’.

Surround systems decode and reproduce the 5.1 channels directly. Dolby Digital EX and DTS-ES

enhanced decoding systems create one extra rear channel from information buried in the two surround

signals of the 5.1 source. These EX and ES enhanced systems are sometimes referred to as ‘6.1’

systems. This extra surround back channel is normally reproduced through two separate loudspeakers,

creating a ‘7.1 system’.

5.1 Playback on 7.1 speaker systems

When listening to 5.1 channel digital recordings, such as Dolby Digital and DTS on a 7.1 channel speaker

system you will have two speakers producing no sound. These two surround back speakers can be

assigned the same signal as the surround speakers in the ‘Speaker Sizes’ page of the Set-up Menu.

When both the surround and surround back speakers are selected the volume from both will be reduced

by 3 dB to keep the sound levels in balance.

Decoding modes

The following modes are available for multi-channel digital sources. Special modes such as DTS-ES 6.1

Matrix and DTS-ES 6.1 Discrete are available only from the correct source material.

For Dolby Digital sources:

Dolby Digital 5.1

Dolby Digital 5.1 Stereo Downmix

Dolby Digital 5.1 Mono Downmix

Dolby Digital Ex

Dolby Digital 5.1 + Pro Logic IIx Movie

Dolby Digital 5.1 + Pro Logic IIx Music

Dolby Digital 5.1 Surround Ex

For DTS sources:

DTS 5.1

DTS 5.1 Stereo Downmix

DTS 5.1 Mono Downmix

DTS-ES 6.1 Matrix

DTS-ES 6.1 Discrete

Dolby Digital 5.1: The most commonly used sound format for DVD video, and is also the standard

for US digital television. Dolby Digital 5.1 sources deliver surround sound with ve discrete full-

range channels; left, centre, right, surround left, and surround right, plus a low frequency effects

(LFE) channel.

Dolby Digital Ex: This is an extension to Dolby Digital decoding that provides a 6-channel output

from a 5-channel input. The extra channel is the centre-surround channel (for which the two

surround back speakers are used), and is derived from the left and right surround channel

information. This decode mode should be used only when the source material is ‘Surround

EX’ encoded (which is normally indicated on the disc packaging and should be detected

automatically by the AV9), but may be used at other times if desired.
