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 matrix 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.

DTS-ES discrete is a true ‘6.1’ source, with six discretely encoded channels, plus the ‘.1’ LFE channel.

Dolby Digital Plus, Dolby TrueHD and DTS-HD are high-resolution surround formats found on Blu-Ray discs

Decoding modes

The modes given in the following table are available for multi-channel digital sources.

Special modes such as DTS-ES 6.1 discrete, Dolby Digital Plus, Dolby TrueHD and DTS-HD are only available from the correct source material.

High resolution audio sources

Dolby TrueHD

Provides up to 7.1 full channel at 96kHz, 24bit resolution, with potentially no

 

losses in the compression process. Data rates can be up to 18Mbps.

Dolby Digital Plus

Provides up to 7.1 discrete channels of audio with less compression than

 

traditional Dolby Digital encoding. Data rates can be up to 6Mbps.

DTS-HD Master Audio

Provides up to 7.1 full channel at 96kHz, 24bit resolution, with potentially no

 

losses in the compression process. Data rates can be up to 24.5Mbps.

For Dolby Digital sources

 

Dolby Digital 5.1

The most commonly used sound format for DVD video, and is also the

 

standard for US television. Dolby Digital 5.1 sources deliver sound with five

 

discrete full-range channels; left, centre, right, surround left, surround right,

 

plus a low frequency effects (LFE) channel.

Dolby Digital 5.1 Stereo

Provides a stereo downmix of the source material for use with headphones.

Downmix

 

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

 

AVR360), but may be used at other times if desired.

Dolby Digital 5.1 + Pro Logic

This mode is used to derive information for the individual surround back

IIx Movie

channels from the surround channels, using the Pro Logic IIx Movie decoder.

Dolby Digital 5.1 + Pro Logic

This mode is used to derive information for the individual surround back

IIx Music

channels from the surround channels, using the Pro Logic IIx Music decoder.

 

The controls for adjusting Pro Logic IIx Music in ‘General Setup’ can be used in

 

this mode.

For DTs sources

 

DTS 5.1

Less common than the Dolby Digital format, but generally recognised within

 

the audio industry as being of superior sound quality. DTS 5.1 delivers

 

surround sound with five full range channels plus an LFE channel.

DTS 5.1 Stereo Downmix

Provides a stereo downmix of the source material for use with headphones.

DTS-ES 6.1 Matrix

This is a 6.1 channel format based on DTS 5.1. It has the sixth channel matrix

 

encoded into the surround left and surround right channels. The sixth channel

 

is a surround centre channel and is directed to the surround back left and

 

surround back right speakers.

DTS-ES 6.1 Discrete

This is a true discrete 6.1 channel sound format (unlike DTS-ES Matrix).

 

DTS-ES discrete mode operates only on sources with DTS-ES 6.1 discrete

 

audio encoding.

DTS96/24

Provides up to 5.1 channels of audio at 96kHz, 24bit resolution for superior

 

sound quality compared to standard DTS 5.1
