for Surround
A “phantom” center channel can be easily
created by connecting the insert send of
the center channel to the insert returns of
the channels designated for left and right.
In the Model 59’s configuration mode, the
left and right channels of the insert section
would be selected for sum, while the
center channel would be set for mute. With
this implementation, however, a level
“buildup” problem may occur. If this is the
case, the source of the phantom center
may need to be attenuated by 6dB (volt-
age). This would be easily accomplished
using a resistor “pad” to drop the level.
With the insert sends capable of driving
600 ohm loads, a simple three resistor
pad would work well; two 150 ohm and
one 300 ohm resistor would do the trick.
Remote Control
Provision has been made to allow remote
control of several system functions. Con-
tact input 1 allows remote activation
of the mute all or dim functions. Contact
input 2 allows remote activation of the
insert 1, insert 2, or bypass functions. The
level control input allows remote control of
the monitor output level. The exact func-
tioning of the remote inputs is dependent
upon the configuration of Model 59 Control
Console parameters. Refer to the Configu-
ration section of this guide for details.
Remote control of mute all or dim is pro-
vided to allow a variety of applications to
be supported. Placing a mechanical switch
adjacent to a telephone, allowing person-
nel to conveniently mute the monitor
loudspeakers, is a perfectly acceptable
application. Allowing a talkback system to
automatically dim the monitor loudspeak-
ers is another typical application.
Remote control of the bypass function is
specifically provided to support interfacing
with an associated console’s PFL/solo
system. By connecting contact input 2 to
a switch or contact closure that indicates
when the PFL/solo system is active, audio
signals connected to the bypass inputs will
automatically be monitored.
The remote level control input is one of
those features which may rarely be used,
but when needed, it’ll really be needed!
Without having support built into the Model
59 Control Console’s hardware and soft-
ware, it would be almost impossible to add
a remote level control later.
The remote level control input, along with
the remote mute all and dim functions,
makes it simple to create a small control
console for secondary locations. The
remote level control input was provided
specifically to allow a producer, director,
or other “big cheese” to have their own
level control for use when previewing
motion picture or video work-in-process.
Note that software “smarts” in the Model
59 Control Console inhibits the use of the
remote level control any time the operator
selects the reference output level. This
ensures that the calibrated monitor level
won’t accidentally be changed by some
maroon. This, along with a remote activity
LED indicator on the Model 59, keeps the
remote level control from doing more harm
than good.
Bypass
The bypass function was expressly pro-
vided so that surround monitoring capabil-
ity can be added to a facility while main-
taining compatibility with existing stereo
monitoring systems. The bypass signal
source would normally be the stereo
