• Downmix Output: An LoRo or LtRt encoded version of the main inputs (Ch. 1-6) is
available from this connector at all times. Optionally, the LfRf source can come from
7/8 to allow separate upmixing and downmixing (see I/O Settings)
2.4 Quick Setup Notes
The Linear Acoustic UPMAX is configured at the factory and is ready to go on the air after
making the proper input and output connections and determining if upmixing is desired.
• Apply a two channel (stereo or LtRt) signal to Main Input 1/2
• The Reference and Main Input front panel indicators should be green.
• The main menu will default to showing output meters, and you should see activity on
some or all of the first six meters.
• Upmixed audio will be output from the Main Out 1-6 AES outputs in the following
format: 1/2 = Left Front/Right Front, 3/4 = Center/LFE, 5/6 = Left Surround/
Right Surround
• Note that 7/8 is the downmix output and will show activity and produce output only
when signals are applied to the LoRo/LtRt encoder inputs.
The best way to learn the processor is to explore the different settings with audio applied
and monitored. There are several factory presets to support many different tastes. Some
presets may not sound much different at first, but will perform very depending on program
content. When in doubt, try turning the upmixing process off or as a last resort use the
Master Bypass feature which will remove the UPMAX completely from the signal path.
