for Surround
As previously discussed, the 4-digit display
indicates the mute condition by showing
four dashes (– – – –).
If the mute all function is active the rotary
level control won’t have an impact on the
post-fader surround and stereo digital and
analog monitor output levels. It’s also not
active whenever the reference level func-
tion is active, except if the auto reference
level off function has been enabled.
Channel Mute/Solo
The channel mute/solo functions allow
specific channels to be selected for indi-
vidual or group mute or “solo” monitoring.
The functions impact the post-fader sur-
round and stereo digital and analog moni-
tor outputs, taking place electrically “after”
the input source selection delay, downmix,
and level control functions.
The mute/solo mode button and the six
channel mute/solo buttons, along with as-
sociated LEDs, work together to provide
excellent operating flexibility. The channel
mute/solo mode button allows the operator
to select between the mute and solo func-
tions. It is also used to select which solo
mode, normal or channel pop, is active.
Going from mute mode to solo mode, or
vice-versa, clears all active mutes or solos.
Pressing the mode button twice is a legiti-
mate means of quickly clearing muted or
soloed channels. To mute or solo a chan-
nel simply requires pressing one of the
channel mute/solo buttons. The buttons
function in a press-to-enable/press-to-
disable “latching” mode. Multiple channels
can be muted or soloed at the same time.
The LED associated with any muted or
soloed channels is used to indicate that
the function is active.
The mute/solo button is also used to select
the solo mode, the choices being normal
or channel pop. Simply press and hold the
mute/solo button for a few seconds until
the LED associated with the solo mode
lights in the desired manner; steady to
indicate normal solo mode and flashing
for channel pop solo mode. Once the state
of the mode has changed as indicated by
the LED (steady-to-flashing or vice-versa)
the desired solo mode becomes active
and the mute/solo button can be released.
The selected solo mode will be maintained
even after the system is powered down
and subsequently powered up.
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 digital and analog
monitor 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 digital and analog monitor output
is set to be 40.5 dB below the maximum
level. As the rotary level control is moved
counterclockwise the output level will go
down and the indicated value will get more
negative.
