for Surround
system’s two surround (5.1) and three
stereo (2-channel) inputs. The configura-
tion mode also allows stereo inputs A and
B to be used as either stereo or monau-
ral sources. This is especially useful in
broadcast applications where a 2-channel
AES3id source may carry two independent
monaural signals. To highlight this powerful
feature: the Model 77B allows independent
monitoring of the two channels associated
with a single AES3id source. Broadcast
master control applications can greatly
benefit from this configuration flexibility.
The surround monitor output level 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 monitor output channels to
automatically mute whenever the output
level is set to its minimum position. Using
the reference level function, the monitor
output level can be set to a pre-configured
value. This is provided for audio-with-
picture applications that require a specific
monitor output level. The reference level
is easily configured by taking an elec-
tronic “snapshot” of the desired monitor
output level. For operator confirmation a
4-digit LED readout can display the level
of the surround 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 surround
monitor output level to be reduced by a
fixed dB amount. The dim level is config-
ured from among four available values. A
mute all function allows all surround moni-
tor output channels to be simultaneously
muted. The channel solo section provides
individual surround channel monitoring
control, allowing a single channel to be
monitored while the others are automati-
cally muted. Multiple channels can also
be simultaneously selected for “soloing.”
A special solo mode is also provided,
called channel pop solo, which offers a
unique aid in monitoring audio material.
