The sophisticated output section monitors faults and generates warnings when appropriate; warnings are
displayed on the front panel of the PLM and also sent as messages over the control network. In the rare
event that maximum ratings are significantly exceeded, the PLM will mute until the condition has been
rectified or the incorrect setting has been readjusted. Sensing circuits also transmit local output power
stage temperature, processor card temperature, and PSU temperature to the appropriate protection circuits.
Please refer to section 5.3 on page 17 further details.
Table 5-1 lists PLM Series analog input sensitivity in dBu and Vrms for various Amp Gain settings and
maximum/minimum ISVPL settings, assuming an analog input headroom of 26 dBu.

5.2 Lake Processing and Control
As outlined in section 2.2.3, this device integrates seamlessly into the Lake Processing environment,
providing all features, functionality and connectivity associated with all Lake Processors. The internal Lake
Processing includes programmable crossovers, EQ, dynamics and other functions, and can be fully con-
trolled via the supplied Lake Controller software. Additionally, many functions can be controlled or accessed
directly via the front panel.
The Lake Controller Operation Manual and Lake Network Configuration Guide are supplied on the accom-
panying CD-ROM or USB key and additional documentation is available from the Start Menu after software
installation.
