for Surround
channels can be muted as required. In 
the solo mode, a single channel can be 
monitored while the others are automati-
cally muted. In either solo mode multiple 
channels can be simultaneously selected 
for “soloing.” The fl exibility of having both 
mute and solo available allows an operator 
to quickly select the most comfortable and 
productive operating mode.
A special solo mode is also provided, 
called channel pop solo, which offers a 
unique aid in monitoring audio material. 
Channel pop solo allows the level of a 
single channel to be raised while the level 
of the other channels is reduced. This 
helps to emphasize the content on one 
channel without fully muting the others. 
Broadcast applications can benefi t from 
this solo mode, allowing, for example, the 
center channel to be highlighted while still 
maintaining some level on the other chan-
nels. The amount of level increase—the 
“pop”—as well as the amount of attenua-
tion can be confi gured to meet the needs 
of specifi c applications.
Two functions allow the format of the 
monitored sources to be checked for level 
or phase inconsistencies. The surround to 
stereo downmix function is used to create 
a stereo signal from the selected surround 
(5.1) source. The stereo to mono downmix 
function allows audio on the left and right 
channels to be added (summed) and moni-
tored on the center output channel. The 
two downmix functions can be simultane-
ously enabled, allowing a surround source 
to be checked for mono compatibility. A 
small speaker simulator feature is associ-
ated with the stereo to mono downmix 
function. It is included to assist an opera-
tor in determining compatibility with “real-
world” playback environments. It functions 
by placing an audio bandpass fi lter into 
the path of the mono signal, simulating the 
response of a loudspeaker associated with 
an inexpensive television or clock radio.
Up to four Model 77 Control Consoles 
can be connected to a Model 76 Central 
Controller. The Model 76 can provide 
power for the fi rst two Model 77 units while
