3.5.6 RALM
Click on the RALM button at the left side of the
DEC-1023 control panel to open this view in the
main window.
The Real-time Audio Level Meter (RALM) visually
displays the status of each audio channel present.
Channels are displayed in pairs, so up to four
meters will be present in the meter display window.
The top section of the window shows a Status
Reporting section on the left, and the audio level
meters on the right.
Status reporting
The Status display shows the status of the functions
monitored by the Audio Probing function of the DEC-
1023 (Optional).
Current status shows the
status now.
Latched status shows the
status as affected by
latching. When an error is detected on a channel, it’s flagged in both sections by
turning red. When the error disappears, the current status returns to green but the
latched status stays marked as an error. Both statuses can be manually cleared by
using the reset button. Only the parameters that have been enabled are reported in
the current status list; the others are grayed out. Each alarm node monitors a channel
(from 1 to 8).
Audio meters
The meter display includes four double meters
Each meter is divided into three zones, and the dividing points and color of
each zone are individually configurable under the Meter Ballistics Config tab.
• The Overload Counter shows a running count of the number of overloads
detected. The Overload level is shown by a marker beside the mater, and
its position can be set under the Meter Ballistics Config tab
• The
Phasemeter (located at the bottom of the RALM meter display) is a
small meter that represents the phase correlation factor between the two
channels of a pair.
