Note: The PGM4 Pre-Fader and PGM4 Pre-On settings affect both
PGM 4 and the Off Line audio. This means the PGM 4 output, which
is still active even when
PGM4 Off Line is checked, could have
some sources active all of the time (if PGM4 Pre-On is checked)
and those could be at a fixed level (if PGM4 Pre-Fader is checked),
which could lead to unexpected operation. Thus, we recommend
not using the PGM 4 bus when Off Line is active (i.e., when the
PGM4 Off Line option is checked for any source). Navigator can be
used to connect a different source to the output labeled as PGM
OUT 4 on the Mix Engine.
PGM4 Pre-Fader – When checked, the signal feeds the Off Line and PGM 4
buses without fader level control (the same level as cue). When
unchecked, the channel fader affects the level feeding both Off Line and
PGM 4.
PGM4 Pre-On – When checked the signal always feeds the Off Line and
PGM 4 buses, unless PGM 4 Pre-Fader is unchecked, in which case the
fader still controls the level. When unchecked, the signal only feeds the Off
Line and PGM 4 buses when the channel is turned on. Typically, this
setting is checked for all sources so that no channels must be on in order
to feed the Off Line bus.
PGM4 Off Line – This setting affects the bus minus signal sent to callers
and remotes. It also affects how the PGM 4 assignment buttons function.
When checked on any source, the PGM 4 buttons also assign the channel
to the Off Line bus. When unchecked on all sources, the PGM 4 buttons
assign channels to the PGM 4 bus and the Off Line bus is not active. For a
caller/remote this means they always hear the bus assigned in the Bus
Minus/Base Mix selection (default setting is PGM 1 for all sources).
Studio Mutes
Any signal can be set to mute one
or more of the monitor outputs
when their channel is turned on, but
typically only microphones are set to
mute outputs. For mics located in the Control Room, both the
CR and Cue
outputs are typically checked (muted). For mics located in a Studio,
typically only the
Studio output is checked (muted), unless cue is fed to
the studio, then Studio and Cue would be checked.
Usually the HDPN output is never checked. Figure 3-10 shows the typical
settings for a CR mic and a Studio mic.
Studio Tallies
Each mic is typically set to trigger one of the
Tallies. Tally 1 is typically used for the Control
Room while Tally 2 is typically used for an
associated talk studio. Tallies 3 and 4 can be
used to trigger hot mic warning lights at two additional locations like a
producer position, call screener, newsroom, etc. Assigning a Tally activates
two Surface displays when a mic channel is on: a red
On-Air indicator
lights up in the Meter Bridge; and a mic icon , shown in the channel
display to the left of the Mode name, which turns red. These mic status
indicators will not be shown if a mic is not assigned to a light a Tally.

Bus-Minus / Direct Out
The DMX includes an internal mono
signal that’s associated with each fader
channel. For a DMX-8 Surface there are
eight check boxes, for a DMX-16 Surface there are sixteen check boxes.
These signals have the default names: DMXBM01
– DMXBM16, with the
BM standing for Bus-Minus , which are audio signals specifically used with
callers and remotes. Any of the mono “BM” signals can alternately be used
as a Direct Out signal to feed an outboard FX unit, air skimmer, or system
monitor.
The settings in this section set which type of signal is generated when
the signal is on a channel. If no boxes are checked a bus-minus signal is
created on any channel that signal is on. When one or more boxes are
checked, and that signal is taken on a checked channel, a Direct Out signal
is created for that channel.
Note: The Direct Out audio is affected by the settings in the Direct
Out Pre-Fader and Direct Out Pre-On sections.
