for Surround
system’s two surround (5.1) and three 
stereo (2-channel) inputs. The confi gura-
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 
benefi t from this confi guration fl exibility.
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-confi gured 
value. This is provided for audio-with-
picture applications that require a specifi c 
monitor output level. The reference level 
is easily confi gured by taking an elec-
tronic “snapshot” of the desired monitor 
output level. For operator confi rmation 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 
confi gured 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 
fi xed dB amount. The dim level is confi g-
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.
