Welcome
2.2.2 Amplifier DSP (Digital Signal Processor)
Various features of PLM Series devices are controlled by the on-board DSP, some of which are summarized
in this section.
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 of the PLM Operation Manual for further information.
2.2.2.3 Load Verification & Performance Monitoring
A comprehensive set of proprietary DSP-based tools are provided for load verification 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
real-time load status, including temperatures of the PLM amplifier 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 verification
and real-time performance monitoring functionality.
2.2.3 Lake Processing and Controller
PLM Series devices integrate seamlessly into the Lake Processing environment and are accessible via the
Lake Controller software. 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
™
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 Analyzer Plug-In
Lake Controller software provides integration with third-party real-time analyzers, providing simultaneous
measurement display and EQ adjustment via the Lake Controller. Approved analyzers include Rational
Acoustics Smaart 7, SysTune from AMFG, and WaveCapture Live‐Capture Light or Live-Capture Pro; ad-
ditional third-party analyzers may be approved in the future.
