for Surround
allows a user to see a visual representa-
tion of the SPL level that is present in the
listening environment. While it takes a little
more care to correctly implement the SPL
display mode, it can offer an enhanced
experience for StudioComm users.
Reference Level in dB SPL
The reference level in dB SPL configu-
ration allows a specific SPL value to be
associated with the stored reference level
value. In this way whenever the moni-
tor output is at the reference level, either
through activating the reference level func-
tion or manually adjusting the rotary level
control, the Model 77’s display will show
the configured SPL level. Whenever the
monitor output is not at the reference value
the display will show the current value, in
dB, relative to the reference level. The ref-
erence level in dB SPL can be configured
over a range of 70.0 to 100.0 dB in one-dB
steps. In many applications a value of 85
would be appropriate, reflecting the widely
used audio-for-picture 85 dB monitoring
reference level. (Typically this 85 dB is
really 85 dBC, indicating that a C-weight-
ing filter has been applied to the mea-
surement.) Other common reference SPL
values, such as 82 and 87, are well within
the allowable range.
Auto Reference Level Off
When auto reference level off is enabled,
the function automatically turns the refer-
ence level function off if a change is made
to the rotary level control while the refer-
ence level function is active.
Dim Level
The dim function is used to reduce the
monitor output level by a preset amount.
The reduction is in dB relative to the
monitor output’s current level. There are
four dim level values available: –10.0,
–15.0, –20.0, and –25.0 dB.
Remote Mute All
Two configuration choices are associated
with the remote mute all function: disabled
and enabled. To utilize the remote mute all
function simply requires you to select the
enabled setting.
Remote Dim
Two configuration choices are associated
with the remote dim function: disabled and
enabled. To utilize the remote dim function
simply configure it for enabled.
LFE Downmix
When the surround to stereo downmix
mode is active the LFE channel typically
mutes. When the LFE downmix mode is
configured for enabled, the LFE channel
is attenuated by 3 dB and mixed into the
left and right channels. This is provided for
special applications and won’t typically be
used.
Channel Pop Solo Mode
Offset Levels
Two parameters can be configured that set
how the channel pop solo function will im-
pact audio levels. The up offset level sets
the amount of increase (gain) that a chan-
nel will experience when it is soloed in the
channel pop solo mode. The down offset
level sets the amount of decrease (attenu-
ation) the non-soloed channels experience
when a channel is active in the channel
pop solo mode.
