6. Feature summary

• Four channels with three levels of total available frame power output: 20000 W, 12000 W and 8000 W

• Rational Power Management (RPM)

• True exibility in allocating power output across each channel to match requirement, for more efcient use

of amplier inventory

• Any channel is capable of delivering up to 5000 W power output 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 uctuations 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 (Conguring Ampliers For the Environment) software incorporates ESP™ (Equipment Specication

Predictor) to assist in design, equipment specication and commissioning

• Features controlled by on-board DSP

• Input Gain (Sensitivity) - Input gain (sensitivity) is set in the digital domain and controlled via CAFÉ software

• ISVPL™ - The Inter-Sample Voltage Peak Limiter (ISVPL) tailors each channel’s power output to the

characteristics of the connected load

• Load Verication & Performance Monitoring - A comprehensive set of proprietary DSP-based tools

enables load verication and real-time performance monitoring
