For฀flexibility,฀the฀system฀is฀designed฀to฀
easily฀integrate฀with฀recording฀consoles,฀
specialized฀playback฀systems,฀and฀audio-
for-picture฀machine-control฀electronics.฀
Four฀hard-wired฀remote-control฀input฀func-
tions฀are฀provided:฀mute฀all,฀dim,฀talkback,฀
and฀input฀select.฀By฀providing฀access฀to฀
the฀StudioComm’s฀mute฀all฀and฀dim฀func-
tions,฀talkback฀or฀slate฀activity฀from฀an฀
audio฀console฀or฀other฀communications฀
system฀can฀control฀the฀monitor฀output฀
level.฀The฀remote฀talkback฀input฀allows฀
an฀externally฀provided฀contact฀closure฀or฀
logic฀signal฀to฀control฀the฀talkback฀function.฀
This฀allows฀easy฀integration฀with฀additional฀
wired฀or฀wireless฀talkback฀devices.฀The฀
remote฀input฀select฀function฀is฀provided฀
expressly฀for฀audio฀post฀applications,฀al-
lowing฀automatic฀switching฀of฀the฀Studio-
Comm’s฀input฀source฀whenever฀the฀mode฀
of฀a฀recording฀system฀changes฀between฀
playback฀and฀record.฀This฀function,฀re-
ferred฀historically฀as฀PEC/direct฀switching,฀
allows฀accurate฀monitoring฀during฀dialog฀
replacement,฀Foley,฀or฀other฀overdub฀฀
sessions.
In฀most฀cases฀Model฀35฀Talent฀Amplifier฀
modules฀will฀serve฀as฀the฀user’s฀head-
phone฀control฀center.฀Each฀Model฀35฀
contains฀amplifier฀circuitry,฀stereo฀level฀
control,฀mono฀switch,฀and฀two฀output฀jacks.฀
For฀convenience,฀a฀microphone฀mounting฀
stand฀adapter฀is฀included฀with฀each฀Model฀
35.฀In฀addition฀to฀the฀talent฀amplifier฀out-
put,฀the฀Model฀74฀also฀provides฀a฀stereo฀
line-level฀cue฀output.฀This฀allows฀interfac-
ing฀with฀other฀headphone฀cue฀systems฀or฀
could฀connect฀to฀a฀transmission฀system฀
associated฀with฀a฀remotely฀located฀studio฀
or฀control฀room.฀The฀line-level฀cue฀output฀
can฀also฀serve฀as฀a฀source฀of฀“slate”฀audio฀
for฀workstations.
Additional฀Details
It’s฀interesting฀to฀note฀that฀while฀each฀
of฀the฀two฀surround฀inputs฀has฀a฀chan-
nel฀that’s฀labeled฀LFE,฀the฀correspond-
ing฀channel฀on฀each฀of฀the฀two฀monitor฀
outputs฀is฀labeled฀SUB.฀The฀term฀LFE,฀an฀
abbreviation฀for฀low-frequency฀enhance-
ment,฀is฀used฀to฀indicate฀an฀audio฀source.฀
So฀LFE฀is฀appropriate฀in฀reference฀to฀the฀
inputs฀Surround฀A฀and฀Surround฀B.฀But฀the฀
term฀SUB,฀short฀for฀subwoofer,฀is฀correct฀
for฀the฀monitor฀outputs฀as฀they฀are฀intend-
ed฀to฀connect฀to฀a฀powered฀subwoofer฀or฀
an฀amplifier฀associated฀with฀a฀subwoofer฀
loudspeaker.฀In฀this฀case฀the฀monitor฀
outputs฀are฀feeding฀subwoofer฀loudspeak-
ers฀which฀are฀reproducing฀the฀LFE฀content฀
