D-subminiature connector is used to con-
nect the Model 76DA with up to four Model
77 or Model 71 Control Consoles. A sec-
ond 9-pin “D-sub” connector is used to
interface with remote control signals. AC
mains power is connected directly to the
Model 76DA, with an acceptable range of
100 to 230 volts, 50/60 Hz.
Additional Details
The Model 77 provides five buttons and
associated LEDs for selection of the sur-
round and stereo input sources to be moni-
tored. While in most cases only one input
source will be monitored at a time, stereo
input C can be selected for simultaneous
monitoring with one of the two surround
or other two stereo inputs. This allows
the two selected inputs to be combined
(“summed”).
The post-fader surround and stereo digital
and analog monitor output levels can be
controlled by way of a large, easy-to-use
rotary control. The control, actually a digital
encoder, allows level selection in precise
0.5-dB steps. The auto mute all function
causes the post-fader surround and stereo
digital and analog monitor output channels
to automatically mute whenever the output
level control reaches maximum attenua-
tion. Using the reference level function, the
post-fader surround and stereo digital and
analog monitor output levels can be set to
a pre-configured value. This is provided for
audio-with-picture applications that require
a specific monitor output level. The refer-
ence level is easily configured by taking an
electronic “snapshot” of the desired moni-
tor output level. For operator confirmation a
4-digit LED readout can display the level of
the post-fader surround and stereo digi-
tal and analog monitor output channels.
To match the needs of a facility, it can be
configured to display either the attenuation
level or the sound pressure level (SPL).
The dim function allows the post-fader sur-
round and stereo digital and analog moni-
tor output levels to be reduced by a fixed
dB amount. The dim level is configured
from among four available values. A mute
