Factory Presets

To get users up and running as quickly as possible, a few basic presets have been created 
for different situations. The name of the game with this unit is “play”. There is no possible 
way that presets appropriate for every situation could be generated, so we have included a 
few to get you started. By all means, make adjustments, listen, store your new preset with 
a name of your choice when you get it just right.

The UPMAX ships with the following factory presets: 

Music Full 

- Straight two-channel to 5.1 channel upmixing, with the center channel 

spread across the Left front, Center, and Right front outputs. This is very useful for 
programming that either contains dialogue with music or is just mono dialogue as it 
nicely fills the front three channels, and feeds the surrounds when appropriate.

MUSIC Narrow

 - Straight two-channel to 5.1 channel upmixing, but with the Center 

channel kept fully discrete with no spread into Left front and Right front channels. 
Useful for film mixes and certain music mixes. Two-channel mono programs will be 
reproduced from the Center channel only. Note that Sum to LFE is enabled by default.

COMMERCIAL DEEP

 - Straight two-channel to 5.1 channel upmix with the Sur-

round audio positioned all the way to the back and the Center channel spread by the 
standard 33%.

Quad

 - Two-channel to 4.1 channel upmixing, with audio coming from Left front, 

Right front, Left surround, Right surround and LFE channels and nothing from the 
Center channel. This preset is useful for creating a surround “bed” with a hole in the 
center into which a wet or ambient announce feed can be added. Innovated by Linear 
Acoustic in 2004, this mode and Quad Spill have found widespread use in sports pro-
duction including the Olympics.

Quad Spill

 - Two channel quad upmixing, but with 33% “spilled” back into the Center 

channel. Since there is some Center information still present, this preset is useful for 
creating a 5.1 channel mix with a dry announce feed (little or no ambient information 
such as audio from a voiceover booth).

Bypass

 - Center Spread set to 100% and Surround Depth set to 0% resulting in two 

channels in, two channels out. Useful for “soft bypass” comparisons, although using 
the Up arrow from the main screen accomplishes the same thing.
