digital
While the Module is On: Program 1 is the Fold-
back mix source. If it’s not assigned, then the
source is selected in this order; Program 2, Pro-
gram 3, Program 4, Off-Line 1, Off-Line 2.
While the Module is Off: Off-Line 1 is the pri-
mary Foldback mix. If it’s not assigned, then Off-
Line 2 is the source. If neither Off-Line is assigned,
there will be no mix-minus audio (except for any
talkback on the left output).
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
input and the caller’s Telco are assigned to O/L 1.
With the Telco module Off, the caller can hear the
talent thru the O/L 1 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 switches to Program 1 (assuming the
air feed is Program 1), so the caller can hear ev-
erything going to air—minus their voice.
Auto-Foldback Of f
When Auto-Foldback is off (the AUTO F/B but-
ton is not lit), the module uses a different bus pri-
ority order.
While the Module is On
or Off: The primary Fold-
back source is Off-Line 1.
If it is not assigned, then
Off-Line 2 is the source.
If it is not assigned then
the program buses are se-
lected in this order; Pro-
gram 1, Program 2, Pro-
gram 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-mi-
nus should not change, thus only Program 1 can
be selected on the Telco and the Program 1 mix-
minus will always be sent back to the remote, re-
gardless of whether the module is On or Off. If a
special remote broadcast mix is required, assign
Off-Line 1 or Off-Line 2 as well, and it will be the
return feed, regardless of the Program bus assign-
ments and whether the module is On or Off.
TELCO RECORD MIX
A two-channel Telco Record Mix output is avail-
able on the Output 1 module.
The left channel has
only the callers from
those Telco modules that
have their TO REC but-
tons lit solid (see page 3-
7 for more info on this
button).
The right channel has
a base mix from one of
the program or off-line
buses. The source for the
base mix is determined
through a bus priority
order, similar to how the
Foldback Mix source is
selected. Again, the high-
est priority bus assigned on any TO REC Telco
becomes the source for the base mix—even if more
lower priority buses are assigned on more TO REC
Telco modules.
Typically, only one caller is recorded at a time,
but, because there can be up to six Telcos, and
each module can have completely different assign-
ments, the TO REC buttons not only record en-
able a module, they also indicate whether or not
that Telco is actually being recorded.
When the TO REC buttons are lit solid, as shown
above, those callers are feeding the left channel of
