created. But spending time establishing
the goals, and what steps are needed to
achieve them, can prove very valuable.
Studying the confi guration chart may at
fi rst 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 channel, e.g., two for left, two for
right, two for center, etc. On the Model
75 Control Console a pushbutton allows
speaker system A or speaker system B to
be selected. The confi guration parameters
allow which of the twelve physical out-
puts 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 confi gurable parameters are related
to the talkback function. The talkback but-
ton on the Model 75 can be confi gured 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 confi gured
so that talkback audio will interrupt and
replace the cue source whenever the talk-
back 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 confi guration option enables or disables
the ability to send a source of cue audio
to the talent amplifi er 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 amplifi er 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 amplifi er and loudspeaker, to cre-
ate a “stage announce” signal.
Solo
Solo operation can be confi gured to sat-
isfy operator preference. The additive solo
mode matches the functionality found in
most recording consoles. In this mode,
multiple channels can be simultaneously
“soloed,” allowing those channels to be
monitored at the same time. Other opera-
tors may prefer the exclusive solo mode.
When this mode is selected, only one
channel can be selected for solo at a time.
The additive solo mode is the default
setting.
Power-Up Mute All
By default, upon application of AC mains
power the monitor outputs remain muted
after the system’s power-up sequence
has been performed. Then an operator
must manually press the mute all button
to enable the monitor outputs. There may
be cases where having the monitor output
channels return to their respective states
as left at the time of the previous loss of
AC mains power, allowing normal opera-
tion automatically to resume.
Level Control Response
As expected, the level control on the
Model 75 Control Console is used to ad-
just the output level of the monitor output
