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).

Discrete and Cinema DSP preset parameters

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.
