Analog Input Connector
This female DB-25 connector accepts standard balanced, line level
analog
signals. See diagram below for pin-out information.
Metered Analog Output Connector
This DB-25 connector outputs
analog
signals as de-embedded from the selected sources or downmix, which are eligible for
conversion to analog. See the diagram under
Item J
above for pin-out information.
NOTE:
The
Analog Output Preference
entry within the
Setup
menu is used to determine how this connector outputs
the channel mix when a
DM1
,
DM2
, or
DM3
downmix selection is enabled. The default setting is
Downmix
, which
outputs the channel mix with individual channel scaling (gain settings) intact as determined by the selected downmix (
DM1
,
DM2
, or
DM3
). However, if
Discrete
is selected, then all channels within the downmix are output from these connectors
at full gain
without
scaling of the channels as determined by the selected downmix. See
Analog Output Preference (A-
OutPref)
section on page
30
for information on how to set this parameter.
Reference Setting Rotary Switch
(1-10)
This recessed 10-position rotary switch is used to set the
Analog
and
Digital Reference Levels
for the units level meters, as well
as selecting the
Software Upgrade
function. In the table shown, the
Analog Reference Level
(
Analog
, left column) is the
analog input level needed to turn on the bargraph segment at the associated
Digital Reference Level (
Digital
, right column
)
value.
This is also the location on the bargraph level meter where the color transitions from GREEN to AMBER.
Example:
Choosing
position
2
(
0 dBu = -20 dBFS
) means an analog input level of
0 dBu
will light up the LED segment associated with the digital
-20
dBFS
value on the bargraph meter and also transition from GREEN to AMBER at that segment.

Selected/Downmix Analog Output Connectors (Left and Right)
These two 3-pin male XLR connectors are
