PLM Series Operation Manual rev 1.1.9
Firmware Version (FW Version)
This option displays the version numbers for various rmware elements. This information can be used to
verify that the latest rmware is installed and is useful if a technical issue arises.
Inherent Latency (Inh. Latency)
This option displays a screen showing latency currently incurred through the PLM, measured from input to
output.
Processing of digital audio necessitates a small but nite processing delay referred to as system latency. It
may be desirable to know the latency, so the value can be subtracted from any deliberate delay introduced
for loudspeaker time-alignment. In many cases, the system latency is so small compared to time-alignment
delay that it can be ignored.
Serial Number (Serial No.)
The printed serial number on the back panel of the PLM is also electronically embedded in the hardware,
and therefore cannot be removed or altered if stolen.
Max Output Voltage (MaxOutVolt)
Displays the maximum output voltage that can exist across the PLM’s output terminals. This is the absolute
maximum, not the voltage dened by the ISVPL setting.
Max Output Current (MaxOutCurr)
Displays the maximum output current that can be delivered by the PLM, summed across all output chan-
nels.
7.11.5.2 Frame Reset
MENU > FRAME > RESET
Use this option to display a further menu with options to reset all parameters back to their original factory
default values. See section 9.3 for a full list of these values. Two types of reset are provided, Factory Reset
and Soft Reset.
Factory Reset
A Factory Reset will reset all settings and parameters to the original factory-dened default values. This
includes the deletion of any Frame Presets stored within the device. It also resets the IP Address and all
network related settings; a hard power cycle is required to complete this reset.
