Audio Display Unit

2-28 Getting started
The Audio Display Unit is a general purpose, channel strip-related module.
It is designed as a four-channel unit, with four identical display strips inte-
grated into a single module. Dimensions: 162.5 × 190 mm. The drawing
left shows just a one-channel portion of the unit.
If used as a channel-related bar graph, it provides the following functions:
Meter
Two 100-segment bar graphs are used to display the level of a signal that
has been selected as a Meter Source for the corresponding channel.
For Mono channels, both bar graphs feature the same display; for Stereo
channels, left and right information will be displayed on separate bar
graphs.
Meter characteristics can be selected between PPM- and VU-response on a
global basis; both bars will always function in the same mode. Each meter
features an integrated peak-hold function with auto and manual reset.
Two overload indicators are provided, each of them referring to the par-
ticular signal indicated by the corresponding bar graph below. A global
peak-hold function can be set to memorize overload occurrences, even if
the channel is currently unassigned to the strip.
OVL
This red LED below the meter indicates all overload conditions of the
corresponding channel. A global peak-hold function can be set to memo-
rize overload occurrences even if the channel is currently unassigned to the
strip.
DYN
This yellow LED indicates the activity of the channel's Dynamics unit; if
any of the four functions – limiter, compressor, expander, or noise gate – is
active and working, the LED will light.
RES
This LED is reserved for a future function.
GRM
By using a global function, it is possible to change the function of the
right-hand bar graph display from Level to GRM (Gain Reduction Meter).
This change of mode only affects those channels that have a dynamics unit
configured within the signal path.
During GRM Mode, the left-hand bar graph will continue to display the
level (for stereo channels, the higher level of the left- and the right-hand
channel is displayed); while the right bar graph indicates current gain
change as effected by the Dynamics unit.
Bus Assign
This section includes 48 individual LEDs for display of track/group as-
signment, plus eight LEDs for master assignment from the corresponding
channel. The ST LED indicates that Stereo Master Bus assignments are
selected for viewing (as set on the Central Assign Unit).
Note: Due to the configurability of the system, it is possible that some of the
functions described above are not installed on particular consoles.
