Introduction
E SERIES E 20:4
The E 20:4 has smart green credentials delivering low lifetime cost of ownership.
Features
-
2,000 W amplifier carrying 4 flexible output channels in a high power density 1 rack unit form factor saves rack space and system cost
-
Energy efficient for supreme green credentials and exceptionally low lifetime running costs
-
Flexible IntelliDrive permits delivering the 4 x 500 W on any channel for all loads (low impedance 2, 4, 8 or 16 Ohms or Hi–Z 70 V or 100 V)
-
Asymmetric channel loading allows mixing and matching loads with different impedances to maximize overall system efficiency and inventory utilization
-
High efficiency amplifier with low power consumption and minimized heat generation lowers demands on the installations’ mains distribution and cooling systems
-
IDEEA outputs stage based on proprietary, state–of–the–art Class–D amplifier technology for superior performance
-
Comprehensive fail safe circuit protection ensures continued operation even under reduced operating conditions
-
Auto–standby and auto–power on reduces power consumption in non–operating cycles
-
Rail Sense Limiter (RSL) greatly reduces signal clipping and ensures simple configuration for constant voltage and low impedance loads
-
Built in 50 Hz high pass filter selectable per channel available on rear panel switch
-
Per channel attenuation knob and signal LED on rear panel for simple commissioning
-
Efficient cooling with temperature controlled fan with front to back airflow
-
Aluminum front panel with power and temperature LEDs and per–channel signal and limit LEDs
-
GPIO connector with power control and indication for further system integration
-
Balanced high–quality analog inputs and amplifier outputs on detachable screw terminals
