Display and Display Mode
The Model 77’s 4-digit LED display shows
the post-fader surround and stereo digital
and analog monitor output levels as either
the amount of attenuation or the sound
pressure level (SPL). Both will indicate
level in dB. What the digits actually repre-
sent will depend upon how the Model 77
has been configured.
Display in dB of Attenuation
If configured for the attenuation mode
the display will show the post-fader moni-
tor output level as an attenuation value in
reference to the maximum output. This is
in the form of 0.5-dB steps less than the
maximum of 0.0 dB. So a display of –40.5
would indicate that the surround or stereo
Input Delay
Two input delay settings, A and B, can be
selected and saved during system con-
figuration. These are provided for aligning
the audio input signals with latencies as-
sociated with video processing and display
systems. During normal operation of the
StudioComm system the active input delay,
A or B, can be selected. The channel mute/
solo button, stereo to mono button, and 4-
digit display are used to display and select
the input delay. When the mute/solo button
is pressed and held the LED associated
with the stereo to mono button indicates
whether input delay A or input delay B is ac-
tive. The 4-digit display will show the active
delay time in milliseconds. While pressing
and holding the mute/solo button the stereo
to mono button can be pressed to change
the selected input delay. Refer to Figure 10
for details. The selected input delay will be
During normal operation, press and hold the Mute/Solo button
