Engage Fold-Down for Main
Enable the Engage Fold-Down for Main option
(Type 1) to automatically fold down the MAIN
CR Path from the selected
Format (such as 5.1 ) to
the selected Fold Down setting (such as Stereo ).
Engage Fold-Down for ALT
Enable the Engage Fold-Down for ALT option
(Type 1) to automatically fold down the ALT CR
Path from the selected
Format (such as Stereo ) to
the selected Fold Down setting (such as Mono ).
Control Room Fold-Down
The Control Room Fold-Down setting (Type 2) de-
termines whether or not to fold-down between
the MAIN and ALT CR Paths.
For example, if the MAIN CR Path Format is set
to 5.1 and ALT is set to Stereo , and the Control
Room Fold-Down setting is set to Fold-Down Be-
tween CR Paths , enabling ALT on the front panel
of HD OMNI folds down the 5.1 MAIN CR Path
to the Stereo ALT CR Path.
Fold Down Between CR Paths Select this option
to fold-down from the CR Path with the larger
Format setting (channel format) to the CR Path
with the smaller Format setting, whether from
MAIN to ALT or from ALT to MAIN.
For example, if MAIN is 5.1 and ALT is Stereo ,
MAIN will fold down to ALT. However, if MAIN
is
Mono and ALT is Stereo , ALT will fold down to
MAIN.
Do Not Fold Down Between CR Paths Select this
option to disable fold down between the MAIN
and ALT CR Paths.
For example, if the MAIN Control Room moni-
tor path is set to 5.1 and the ALT Control Room
monitor path is set to Stereo, only the front Left
and Right channels of the 5.1 source are heard
in the ALT Stereo monitor output path and the
other source channels are not.
Headphone Fold Down
The Headphone Fold-Down setting (Type 3) deter-
mines how the CR Path channels are folded
down to stereo for headphone monitoring.
Fold Down If Control Room Is Larger Than
Stereo
Select this option to fold down any
greater-than-stereo CR Path to stereo for head-
phone monitoring.
For example, if the MAIN CR Path Format is set
to 5.1 , those channels fold down to stereo for
headphone monitoring.
Fold Down Without LFE (If Present) Select this
option to fold down any greater-than-stereo CR
Path to stereo for headphone monitoring, but
not passing the LFE channel if present (such as
with 5.1).
Do Not Fold Down (L/R Channels Only) Select
this option to not fold down from a greater-
than-stereo CR Path and only pass the Left and
Right channels for headphone monitoring. All
other channels are not heard on the headphone
monitoring path.
Engage Fold-Down for MAIN can also be
enabled from the front panel in SETUP
mode (see Chapter 5, “SETUP Mode”).
Engage Fold-Down for ALT can also be en-
abled from the front panel in SETUP mode
(see Chapter 5, “SETUP Mode”).
