AutoMAX TM Mode
This mode will automatically switch between stereo and 5.1 at its input to
provide 5.1 output at all times. This ensures a fully automatic delivery of 5.1
audio to the consumer.
Note: When AutoMAX™ is enabled, the input channels 1-2 (L/R) are
always up-mixed onto outputs 1-6 (L/R/C/LFE/Ls/Rs). If input
channels 3-6 are also present then these signals are mixed onto
the up-mixed C/LFE/Ls/Rs outputs. In summary there is no
dynamic signal detection between 5.1 and stereo inputs.
Up-Mix Processing Times
Up-Mix processing takes one video frame to perform.

Up-Mix 1
The Imagestore 750 has built-in video delays that allow the user to
compensate for this delay. This is covered for Dolby modules on page 375,
and exactly the same principles apply to Up-Mix.
