Meter Mode - Lab.gruppen PLM Series Operation Manual

9 FRONT PANEL INTERFACE

9.12 Meter Mode

In METER mode, there are three possible screen
displays, referred to as "Views". Pressing the METER
button scrolls through the three views in turn: Home,
Module and Temperature. Each of the three views
provides different information about the PLM's
performance and settings.
The three views are similar in layout. The display
screen is divided into eight "blocks", arranged in two
columns of four, so that each block is associated with
one soft button/tricolor LED. Each block has four
rows of alphanumeric characters, either showing
textual information or acting as bargraph meters.
In addition, four sets of alphanumeric characters
are displayed in inverse video in the screen
center between the left and right columns. These
provide confirmation of the PLM's Module/output
configuration. The letters A or B refer to the two
Dolby Lake processing modules, and the numbers
1-4 to the PLM's output channels. Two examples of
displays are given as illustration:
If the processor is configured as two independent
2-way crossovers, the relationship between inputs
and outputs will be indicated as shown:

Figure 9.12a: Dual 2-way crossover configuration
This indicates that output channels 1 and 2 are driven
from Module A and output channels 3 and 4 from
Module B.
If the processor is configured as a single 4-way
crossover, the relationship between inputs and
outputs will be indicated as shown:

This indicates that all four output channels are driven
from Module A.
In general, the four display blocks in the right-hand
column (5-8) provide information relating to the output
sections or Dolby Lake processor Module outputs,
while the center two blocks in the left-hand column
(2 & 3) provide information relating to the inputs to
the amplifier or the Dolby Lake processor Module
inputs. The upper and lower blocks in the left-hand
column (1 & 4) display global information about the
PLM (Frame data).
