PLM Series Operation Manual rev 1.1.9

2.2.2.1 Input Gain (Sensitivity)

Input gain (sensitivity) is set in the digital domain for PLM Series devices, and may be controlled via the

Lake Controller software or front-panel interface.

2.2.2.2 ISVPL

™

The Inter-Sample Voltage Peak Limiter (ISVPL) tailors each power output to the characteristics of the

connected load. Please refer to section 5.3.1 for further information.

2.2.2.3 Load Verication & Performance Monitoring

A comprehensive set of proprietary DSP-based tools are provided for load verication and real-time perfor-

mance monitoring. These functions utilize LoadLibrary, a comprehensive database for each loudspeaker

component of the connected load (usually one or more band-limited drivers in a multi-way system).

Using this data and a brief test signal, LoadSmart compares actual response to predicted response, identify-

ing any malfunctioning components or connection errors. During the performance, SpeakerSafe

™

monitors

real-time load status, including temperatures of the PLM amplier stages as well as magnets and voice

coils of connected loudspeakers. This allows operators to avoid power compression and identify potential

problems.

Please refer to the Lake Controller Operation Manual for detailed information on PLM Series load verication

and real-time performance monitoring functionality.

2.2.3 Lake Processing and Controller

PLM Series devices integrate seamlessly into the Lake Processing environment. Two processing modules

offer precise settings for gain, delay, crossover settings, equalization and limiting. Lake processing features

incorporated in each module include Raised Cosine Equalization

™

, linear phase crossovers, and LimiterMax

™

loudspeaker protection. The Super Module feature allows hardware processing modules in two or more

separate devices to function as a single module in the Lake Controller software. Please refer to the

Lake Controller Operation Manual for further information.

2.2.4 Lake Analyzer Bridge

Lake Controller software provides integration with third-party real-time analyzers, providing simultaneous

measurement display and EQ adjustment via the Lake Controller.

The third-party measurement tools that can be integrated via the Analyzer Bridge include:

▸ Smaart Live Version 5.4

▸ Live-Capture Light / Live-Capture Pro
