for Surround
When the surround to stereo downmix
function is active the left surround (LS)
input is routed to the left (L) post-fader
monitor output; the right surround (RS)
input is routed to the right (R) post-fader
monitor output. By default the level of the
LS and RS signals routed to L and R will
be reduced (attenuated) by 3 dB. An alter-
nate setting allows the levels to be reduced
by 6 dB. (These settings can also be
notated as –3 dB and –6 dB.)
When the surround to stereo downmix
function is active the center (C) input is
routed to both the left (L) and right (R)
post-fader monitor outputs. By default the
level of the C signal routed to L and R will
be reduced (attenuated) by 6 dB. An alter-
nate setting allows the attenuation level to
be 3 dB. (These levels can also be notated
as –3 dB and –6 dB.)
By default, when the surround to stereo
downmix function is active the LFE chan-
nel associated with a surround input is
fully attenuated (muted). This removes
LFE content from the “downmixed” signal.
In most applications this is appropriate.
However, for special situations a configura-
tion mode allows the LFE channel to be
reduced by 6 dB and routed to both the
left (L) and right (R) post-fader monitor
outputs.
A last word on configuring the surround to
stereo downmix function: no matter what
choices are made when the function is
active the center (C), left surround (LS),
right surround (RS), and subwoofer (SUB)
post-fader monitor outputs will fully mute.
Pre-Fader Surround Monitor
Output Mode
The pre-fader surround monitor output can
be configured as to its place in the Model
76D’s signal flow. The choices are pre- or
post-downmix. In the pre-downmix mode
the monitor output channels will not be
impacted by the state of the downmix func-
tions. This setting would be appropriate
if the pre-fader surround monitor outputs
were being routed to a storage system,
routed to another facility, etc. In this case
the action of an operator enabling or dis-
abling the downmix functions won’t impact
the pre-fader surround monitor output sig-
nals. If the post-downmix mode is selected
the pre-fader surround monitor outputs will
reflect the actions of the downmix func-
tions. This choice would be correct if, for
example, level meters were connected to
the pre-fader surround monitor outputs.
In this scenario an operator would want
to visually observe the actions that the
downmix functions impart on the signals.
Channel Pop Solo Mode
Offset Levels
Two parameters can be configured that de-
termine how the channel pop solo function
impacts audio levels. The up offset level
sets the amount of increase (gain) that a
channel will experience when it is soloed
in the channel pop solo mode. The down
offset level sets the amount of decrease
(attenuation) that the non-soloed channels
will experience when a channel is active
in the channel pop solo mode.
