Figure 7-17: Frame Menu
The Frame Menu provides information and options relating to the PLM as a physical unit. It is referred to as
a Frame for consistency with Lake Controller terminology.
The Frame Label as defined in the Lake Controller is displayed in this menu. It is also displayed at the
top-left of the screen in Meter Mode, Home View.
7.11.5.1 Frame Info
MENU > FRAME > FRAME INFO
Frame Info provides information about the device settings and configuration. All data in this front panel
menu is read-only; some parameters are fixed, some can be changed only via the Lake Controller software.
Firmware Version (FW Version)
This option displays the version numbers for various firmware elements. This information can be used to
verify that the latest firmware 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 finite 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.
