for Surround
A฀special฀mode฀has฀been฀included฀to฀
disable฀an฀input฀from฀being฀accessed฀
by฀the฀operator.฀This฀might฀be฀useful,฀for฀
example,฀when฀Stereo฀B฀is฀not฀connected฀
to฀a฀source,฀and฀has฀no฀valid฀reason฀to฀
be฀selected.฀This฀might฀also฀be฀useful฀
when฀connecting฀a฀special฀source,฀such฀
as฀a฀house฀“tie฀line”฀or฀router฀output,฀that฀
shouldn’t฀normally฀be฀accessible.฀Disabling฀
an฀input฀is฀simple฀to฀perform,฀just฀disable฀
all฀channels฀associated฀with฀it;฀six฀for฀Sur-
round฀A฀and฀B,฀two฀for฀Stereo฀A฀and฀B.฀To฀
confirm฀that฀an฀input฀has฀been฀disabled,฀all฀
LEDs฀associated฀with฀that฀input฀will฀flash฀
on฀and฀off.฀Once฀the฀Model฀75฀is฀returned฀
to฀the฀normal฀operating฀mode฀the฀disabled฀
input฀cannot฀be฀selected.
Speaker฀Systems/Monitor฀Outputs
The฀configuration฀parameters฀associated฀
with฀the฀speaker฀system฀selection฀but-
ton฀and฀monitor฀output฀channels฀offer฀an฀
extremely฀powerful฀resource.฀With฀just฀a฀
few฀button฀presses฀a฀wide฀range฀of฀moni-
tor฀system฀implementations฀can฀be฀easily฀
created.฀But฀spending฀time฀establishing฀
the฀goals,฀and฀what฀steps฀are฀needed฀to฀
achieve฀them,฀can฀prove฀very฀valuable.฀
Studying฀the฀configuration฀chart฀may฀at฀
first฀be฀confusing฀but฀should฀soon฀cause฀
comments฀such฀as฀“cool”฀and฀“wow,฀I฀can฀
really฀do฀that?”฀to฀spill฀out!฀
Physically,฀the฀Model฀74฀Central฀Controller฀
supports฀the฀connection฀of฀two฀6-channel฀
monitor฀loudspeaker฀systems.฀They฀are฀
designated฀A฀and฀B.฀This฀means฀that฀there฀
are฀two฀output฀connections฀for฀each฀chan-
nel,฀e.g.,฀two฀for฀left,฀two฀for฀right,฀two฀for฀
center,฀etc.฀On฀the฀Model฀75฀Control฀Con-
sole฀a฀pushbutton฀allows฀speaker฀system฀
A฀or฀speaker฀system฀B฀to฀be฀selected.฀
The฀configuration฀parameters฀allow฀which฀
of฀the฀twelve฀physical฀outputs฀are฀active฀
when฀speaker฀system฀A฀is฀selected,฀and฀
which฀of฀the฀twelve฀physical฀outputs฀are฀
active฀when฀speaker฀system฀B฀is฀selected.฀
There฀are฀no฀restrictions฀on฀what฀outputs฀
are฀active฀in฀any฀situation.
Talkback
Four฀configurable฀parameters฀are฀related฀
to฀the฀talkback฀function.฀The฀talkback฀but-
ton฀on฀the฀Model฀75฀can฀be฀configured฀to฀
operate฀in฀either฀a฀push-to-talk฀or฀latching฀
(push฀on/push฀off)฀mode.
The฀talkback฀function฀can฀be฀set฀to฀add฀
(sum)฀talkback฀audio฀with฀the฀selected฀฀
cue฀source.฀Alternately,฀it฀can฀be฀config-
ured฀so฀that฀talkback฀audio฀will฀interrupt฀
and฀replace฀the฀cue฀source฀whenever฀the฀
talkback฀function฀is฀enabled.
The฀talkback฀audio฀source฀can฀be฀selected฀
from฀two฀choices.฀In฀most฀cases฀it’s฀appro-
priate฀to฀use฀the฀microphone฀contained฀฀
in฀the฀Model฀75.฀For฀more฀specialized฀฀
applications฀a฀source฀connected฀to฀the฀
line-level฀talkback฀input฀can฀be฀effective.
A฀configuration฀option฀enables฀or฀disables฀
the฀ability฀to฀send฀a฀source฀of฀cue฀audio฀
to฀the฀talent฀amplifier฀and฀line-level฀cue฀
outputs.฀Typically฀this฀option฀will฀be฀set฀
for฀enable.฀In฀certain฀situations฀it฀may฀be฀
desirable฀to฀only฀send฀talkback฀audio฀out฀
the฀talent฀amplifier฀and฀line-level฀talkback฀
outputs.฀An฀example฀of฀where฀this฀setting฀
could฀be฀appropriate฀is฀when฀one฀of฀the฀
line-level฀talkback฀outputs฀is฀used,฀along฀
with฀an฀amplifier฀and฀loudspeaker,฀to฀cre-
ate฀a฀“stage฀announce”฀signal.
Solo
Solo฀operation฀can฀be฀configured฀to฀sat-
isfy฀operator฀preference.฀The฀additive฀solo฀
mode฀matches฀the฀functionality฀found฀in฀
most฀recording฀consoles.฀In฀this฀mode,฀
