4.5.4

Selects the preset to be recalled via GPI controls 1 through 4.
4.5.5
Monitor Mode
determines whether outputs 1 - 6 are multichannel output or the output from the downmix
stage. Note: This is a global adjustment and affects, the Analog outputs, AES outputs, and
HD-SDI output.
4.5.6
Upmix LfRf When
Controls how upmixing is engaged. Selections include:
•
Set On Now (Local Control)
•
Set off now (Local Control)
4.5.7
When Upmixing, (Mute Ch 3 - 6 / Do Not Mute)
Because Input 2 (C/LFE) and 3 (Ls/Rs) are also inputs to the Downmix encoder, it is nec-
essary to mute these inputs when using the upmixer and downmixer together. The upmixer
will always mute these inputs, and this setting allows the same thing to happen for the
downmixer. When using the downmixer for a separate program not related to the audio
applied to the upmixer, set this to Do Not Mute.
4.5.8
Downmix Type
Set for LoRo ITU style stereo downmix or LtRt surround downmix compatible with Dol-
by Pro Logic and Pro Logic II. Note that the LtRt setting introduces an additional 5 msec
of delay on the 7/8 output due to additional filtering requirements of this mode.

Routes the downmix to output 7/8.
4.5.10
Downmix Center Level
