The 20000DP AMPLIFIER8.1 Main featuresThe 20000DP incorporates a number of sophisticated technologies to ensure the best possible performanceand many years of reliable operation. The following section summarizes the benefits of each feature; additionalinformation is available in the reference manuals.8.1.1 Amplifier PlatformThe 20000DP features extraordinary power density, patented Class TD® output stages, Regulated Switch ModePower Supply (R.SMPS™), the high-efficiency Intercooler® copper-finned cooling system, and a full suite ofprotection features. Signal inputs are analog, AES digital, and Dante digital audio network; loop-through outputs orredundant pairs are provided for each input type.Please refer to the 20000DP Operation Manual for further information.8.1.2 Amplifier DSP (Digital Signal Processing)Various features are controlled by the on-board DSP, some of which are summarized in this section.8.1.2.1 Input Gain (Sensitivity)Input gain (sensitivity) is set in the digital domain, and may be controlled via the Lake Controller software or front-panel interface.8.1.2.2 ISVPL™The Inter-Sample Voltage Peak Limiter (ISVPL) tailors each power output to the characteristics of the connected load.Please refer to the 20000DP Operation Manual for further information.8.1.2.3 Load Verification & Performance MonitoringA comprehensive set of proprietary DSP-based tools are provided for load verification and real-time performancemonitoring. These functions utilize LoadLibrary, a comprehensive database for each loudspeaker component of theconnected 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, identifying anymalfunctioning components or connection errors. During the performance, SpeakerSafe™ monitors real-time loadstatus, including temperatures of the 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 load verification and real-timeperformance monitoring functionality.8.1.3 Lake Processing and Controller |
