3 Operation
Auto-Foldback On is the most common setting
for call-in contests or interviews where the caller
will go live on-air. Typically, only the talent’s mic
module and the caller’s Telco module are assigned
to the Offline (O/L) bus. With the Telco module
Off, the caller can hear the talent thru the offline
bus, and the talent can hear the caller through
either the Telco Monitor output or Cue. When the
Telco module is turned on, the mix-minus feed is
switched to Program 1 (assuming the air feed is
Program 1), so the caller now hears everything
going to air—minus their own voice.
Auto-Foldback Off
When Auto-Foldback is off (the AUTO button
is not lit), the module uses a different bus priority
order.
While the Module is On or Off, the primary
foldback source is Off-Line. If it is not assigned
then the program buses are selected in this order;
Program 1, Program 2, Program 3, Program 4.
Auto-Foldback Off is the most common setting
for recording callers for later broadcast and for
doing a live remote where a “broadcast” feed to
the remote site is required. In
a remote broadcast, when the
remote talent goes on-air, the
mix-minus should not
change, thus only Program 1
can be selected on the Telco
and its mix-minus will al-
ways be sent back to the re-
mote, regardless of whether
the module is On or Off. If a
special remote broadcast mix
is required, assign Off-Line
as well, and it will be the re-
turn feed, regardless of the
Program bus assignments
and whether the module is
On or Off.
TELCO RECORD MIX
A two-channel Telco Record Mix output is avail-
able in analog and digital format on the Output 1
module.
The left channel has only the callers from the
Telco modules that have their TO REC buttons lit
solid (see page 3-6 for more info on this button).
The right channel has a base mix (one program
or the off-line bus). The source for the base mix is
determined by a bus priority order, similar to how
the Foldback Mix source is selected. Again, the
highest priority bus assigned on any TO REC en-
abled Telco becomes the source for the base mix—
even if more lower priority buses are assigned on
more TO REC enabled Telco modules.
Typically, only one
caller is recorded at a
time, but, because
there can be up to
four Telcos, and each
module can have
completely different
assignments, the TO
REC buttons not only
record enable a mod-
ule, they also indicate
whether or not that
Telco is actually being
recorded.
When the TO REC
buttons are lit solid,
as shown to the right,
those callers are feed-
ing the left channel of the record output. When
the TO REC button is “winking,” (as shown on the
next page) it indicates that caller is NOT being
recorded.
As with creating the Foldback Mix, the bus pri-
ority order changes when a TO REC Telco has
Auto-Foldback enabled. But, there is added com-
plexity since multiple modules can have AUTO
Base Mix Source
(feeds the right
channel of the
Telco Record
Outputs)
TO REC buttons are
lit solid: both are
feeding the left
channel of the
Telco Record
Outputs.
