9.13.5.2 Frame Info

This option is selected by pressing soft button 3, (Frame Info) from Menu è Frame. It provides the user
with various fixed information about the PLM and its current settings. This display shows data only, which
cannot be modified.

9.13.5.2.1 Firmware version ('FW version')

Selecting this option displays a page showing the version numbers of the various firmware elements within
the PLM. This information may be of relevance if a technical issue should arise; factory technical staff will
probably request these numbers.

9.13.5.2.2 Latency ('Inh. Latency')

Any processing of audio signals in the digital domain necessitates a small but finite processing delay. This is
termed system latency. It may be desirable to know what the latency is, so that its value may be subtracted
from any delay deliberately introduced into the signal chain by the user for reasons of loudspeaker time-
alignment. In many cases, the latency will be sufficiently small compared with any time-alignment delay that
it can be ignored.
The page displayed when this option is selected shows the latency currently incurred through the PLM,
measured from input to output.
