DSP presets for multichannel material

Multichannel audio signals can come from either encoded data

streams (such as Dolby Digital) or as discrete channels from a DVD

player. If you are using Meridian SmartLink then all formats will

reach the G68 as discrete channels. With suitable loudspeakers the

G68 can upsample these to provide a more enjoyable surround

experience.

The G68 Digital Surround Controller will automatically select the

right decoder algorithm and present the same set of preset choices

for all streams. Note: Some presets are only available if there are

four surround speakers in the system.

There are four multichannel Music presets:

• Discrete, PLIIx Mus6, THX Music, and Ambisonics B format

(discrete inputs only).

There are five multichannel Movie presets:

• Cinema, PLIIx Mov6, THX, THX Surround EX, and THX Ultra2

Cinema.

The multichannel Music presets all use the Music speaker layout

and the multichannel Movie presets all use the 5.1 Movie speaker

layout; see

Speaker layouts

, page 43.

Cinema

The Cinema preset is recommended for listening to multichannel

movie soundtracks when no further processing is required.

Discrete

The Discrete preset is similar to Cinema, except that it uses the

Music speaker layout and sets the LFE level to -10dB.
