for Surround
An LFE low-pass filter function is provided
as a means of checking the audio content
in the selected input’s LFE channel. The
operator can enable and disable the func-
tion as required, helping to ensure that the
proper signals are being mixed to the LFE
channel. Having the correct mix content is
critical as the LFE channel is often band-
restricted during distribution.
The monitor output level can be controlled
by way of a large, easy-to-use rotary
control. The “curve” or “taper” of the level
control can be configured to match an op-
erator’s preference. The choices available
are true logarithmic and modified logarith-
mic. The level control auto mute-all func-
tion allows the monitor output channels to
automatically mute whenever the rotary
level control is in its fully counterclockwise
(minimum) position. This is useful in ap-
plications such as broadcast. By using the
reference level function, the monitor output
level can set to a preconfigured value. This
is provided for applications that require a
specific monitor level to be quickly select-
ed. The reference level is easily configured
by taking an electronic “snapshot” of the
position of the rotary level control. For op-
erator confirmation, the 4-digit LED read-
out displays the level of the monitor output.
For operator convenience, the dim function
allows the monitor output level to be
reduced by a fixed dB amount. The mute-
all function allows one button to simul-
taneously mute all eight monitor output
channels. The input mute/solo section
provides individual input channel control.
One push-button switch sets the operat-
ing mode for either mute or solo. In the
mute mode, individual input channels can
be muted as required. In the solo mode,
one channel can be monitored while the
others are automatically muted. Depend-
ing on the configuration, multiple channels
can be simultaneously selected for “solo-
ing.” The flexibility of having both input mute
and input solo available allows an operator
to quickly select the most comfortable and
productive operating mode.
Two output mute functions are also provid-
ed. One button allows the seven main out-
put channels to be directly muted. A second
button allows the subwoofer monitor output
channel to be muted. The output mute func-
tion, along with the input mute/solo func-
tion, allows an operator complete flexibility
when checking an input source and its path
to the loudspeaker system. These mute and
solo resources are crucial in a multichan-
nel environment, especially when signals
are passing through a bass management
system.
The Model 79 Control Console connects
to, and is powered by, the Model 78 Central
Controller. The Model 79 generates MIDI
system-exclusive messages to control the
Model 78. Remote-control signals con-
nected to the Model 78 Central Controller
are routed to the Model 79 via pins in the
interconnecting cable.
Remote Control Capability
For flexibility, the StudioComm for Surround
system is designed to easily integrate with
recording consoles, studio communications
systems, and film motion-control electron-
ics. Three remote-control input functions
are provided: mute all, dim, and input
source override. By providing access to the
StudioComm’s mute all and dim functions,
talkback or slate activity from an audio
console or other communications system
can control the monitor output level. The
input source override function is provided
expressly for film post applications, allowing
automatic switching of the StudioComm’s
