Feature summary
Amplifier Platform Features
• Four channels with four levels of total available frame power output: 20000 W, 12000 W, 8000 W, and 5000 W (@ 2.67 ohms)
• Rational Power Management (RPM)
• True flexibility in allocating power output across each channel to match requirement for more efficient use of amplifier inventory
• Any channel is capable of delivering up to 5900 W (PLM 5K44 = 2000 W) power output drawing from total available power in each frame
• Dedicated on-board surveillance and load monitoring for voice alarm applications
• Advanced universal power supply
• Regulated Switch-Mode Power Supply (R.SMPS™) maintains stability through fluctuations in mains voltage
• Best-in-class Power Factor Correction (PFC)
• Current Draw Modeling (CDM™) reduces peak mains draw
• Breaker Emulation Limiter (BEL™) responds to available mains distribution
• Under-Voltage Limiting (UVL™) allows continued operation through mains voltage drop
• CAFÉ (Configuring Amplifiers For the Environment) software incorporates ESP™ (Equipment Specification Predictor) to assist in design,
equipment specification and commissioning
• Features controlled by on-board DSP
• Amp Gain (Sensitivity) - Input gain (sensitivity) is set in the digital domain and controlled via Lake Controller software
• ISVPL™ - The Inter-Sample Voltage Peak Limiter (ISVPL) tailors each channel's power output to the characteristics of the connected load.
• Load Verification & Performance Monitoring - A comprehensive set of proprietary DSP-based tools enables load verification and real-time performance monitoring.
Lake Processing Features
