for Surround
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
monitor output is set to be 40.5 dB below
the maximum level. As the rotary level con-
trol is moved counterclockwise the output
level will go down and the indicated value
will get more negative.
Display in dB SPL
If the Model 77 is configured to display
the post-fader digital and analog monitor
output level in dB SPL, the 4-digit display
will always show the output level in positive
numbers. These numbers are intended
to represent the sound pressure level
in dB SPL, a figure that should directly
indicates whether input delay A or input
delay B is active. 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 stored in non-
volatile memory so a power down/power
up cycle will not change the selection.
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.
During normal operation, press and hold the Mute/Solo button
to view and change the solo mode and input delay settings. 
This LED displays the current setting
of the solo mode. LED not lit means
normal; LED lit means channel pop.
Press the button to change the mode.
This LED displays the current
setting of the input delay.
LED not lit means input delay A
is selected; LED lit means input
delay B is selected. Press the
button to change the setting.
The display shows the currently
selected input delay in milliseconds.
