Headphone฀Cue฀System/Talkback
The฀headphone฀cue฀system฀and฀its฀associ-
ated฀talkback฀function฀is฀simple฀to฀use,฀but฀
does฀offer฀a฀number฀of฀user฀and฀configura-
tion฀options.฀On฀the฀Model฀75,฀three฀but-
tons฀and฀one฀LED฀are฀used฀to฀control฀these฀
functions.
The฀talkback฀button฀on฀the฀Model฀75฀is฀used฀
to฀enable฀the฀talkback฀function.฀Depending฀
on฀the฀Model฀75’s฀configuration,฀the฀but-
ton฀may฀provide฀a฀push-to-talk฀or฀a฀latching฀
(push฀on/push฀off)฀action.฀In฀most฀cases฀
enabling฀the฀talkback฀function฀will฀also฀
cause฀the฀dim฀function฀to฀enable.฀However,฀
be฀aware฀that฀a฀Model฀75฀configuration฀
does฀allow฀talkback฀to฀not฀enable฀dim.฀The฀
LED฀associated฀with฀the฀talkback฀button฀will฀
light฀whenever฀talkback฀is฀enabled฀using฀the฀
button฀on฀the฀Model฀75.฀Remotely฀enabling฀
talkback,฀using฀a฀hard-wired฀connection฀or฀
an฀infrared฀(IR)฀source,฀will฀cause฀the฀talk-
back฀LED฀to฀flash.
By฀using฀the฀two฀talkback฀level฀buttons,฀
the฀talkback฀level฀can฀be฀selected฀over฀an฀
8-step฀range.฀To฀adjust฀the฀talkback฀level,฀
enable฀the฀talkback฀function฀and฀press฀the฀
up฀or฀down฀button฀as฀required.฀The฀LED฀
associated฀with฀the฀talkback฀button฀will฀flash฀
each฀time฀the฀level฀is฀increased฀or฀de-
creased฀until฀the฀top฀or฀bottom฀of฀the฀range฀
is฀reached.฀At฀this฀point,฀if฀you฀continue฀to฀
press฀the฀same฀level฀button฀the฀LED฀won’t฀
flash,฀indicating฀you’re฀at฀the฀top฀or฀bottom฀
of฀the฀8-step฀level฀range.
Depending฀on฀how฀the฀talkback฀function฀
has฀been฀configured,฀talkback฀audio฀will฀
either฀add฀to฀(sum฀with)฀the฀selected฀cue฀
audio฀source฀or฀it฀will฀replace฀(interrupt)฀
the฀source.฀Note฀that฀it’s฀also฀possible฀to฀
configure฀the฀system฀so฀that฀no฀cue฀audio฀
source฀will฀be฀present฀at฀any฀time.
A฀Model฀75฀function฀allows฀the฀cue฀audio฀
source฀to฀be฀selected฀from฀between฀two฀
choices.฀The฀first฀choice฀is฀the฀left฀and฀฀
right฀audio฀channels฀being฀sent฀to฀the฀
monitor฀outputs.฀These฀channels฀are฀post฀
(after)฀the฀input฀source฀buttons฀and฀the฀
downmix฀functions;฀whatever฀is฀being฀
heard฀out฀of฀the฀left฀and฀right฀monitor฀loud-
speakers฀will฀be฀heard฀in฀the฀headphone฀
cue฀system.฀The฀second฀cue฀audio฀choice฀
is฀Stereo฀B.฀If฀this฀choice฀is฀selected,฀the฀
source฀or฀sources฀selected฀for฀the฀moni-
tor฀outputs฀will฀have฀no฀impact฀on฀what฀is฀
heard฀in฀the฀headphone฀cue฀system.
It’s฀a฀simple฀matter฀to฀determine฀which฀
cue฀audio฀source฀is฀selected฀and,฀if฀de-
sired,฀change฀to฀the฀other฀one.฀When฀the฀
talkback฀function฀is฀not฀active,฀press฀both฀
the฀talkback฀level฀up฀and฀level฀down฀but-
tons.฀The฀four฀input฀source฀LEDs฀will฀no฀
longer฀reflect฀the฀selected฀monitor฀source฀
(or฀sources)฀but฀instead฀will฀display฀the฀
selected฀cue฀audio฀source.฀Observing฀the฀
LED฀associated฀with฀Stereo฀B,฀if฀it฀is฀not฀lit฀
the฀cue฀audio฀source฀is฀the฀left฀and฀right฀
channels฀being฀sent฀to฀the฀monitor฀outputs.฀
If฀the฀LED฀associated฀with฀Stereo฀B฀is฀
flashing,฀the฀cue฀audio฀source฀is฀Stereo฀B.฀
To฀change฀the฀selected฀cue฀audio฀source,฀
press฀the฀Stereo฀B฀button.
Note฀that฀the฀Model฀75฀doesn’t฀provide฀an฀
overall฀level฀adjustment฀for฀the฀cue฀audio฀
and฀talkback฀output฀signals฀that฀are฀sent฀
to฀the฀talent฀amplifier฀and฀line-level฀cue฀
outputs.฀As฀was฀previously฀discussed,฀the฀
relative฀level฀of฀the฀talkback฀audio฀versus฀
the฀cue฀audio฀can฀be฀adjusted.฀This฀re-
flects฀the฀StudioComm’s฀system฀architec-
