 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 G61 as discrete channels. With suitable loudspeakers the 

G61 can upsample these to provide a more enjoyable surround 

experience.

The G61 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 

The Cinema preset is recommended for listening to multichannel 

movie soundtracks when no further processing is required. 

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

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