Introduction
E Series E 2:2
The E 2:2 has smart green credentials delivering low lifetime cost of ownership.
Features
-
200 W amplifier carrying 2 flexible output channels in a high power density 1 rack unit form factor saves rack space and system cost
-
Energy efficient with Energy Star certification for supreme green credentials and exceptionally low lifetime running costs
-
Flexible IntelliDrive permits delivering the 2 x 100 W at constant voltage 70 V or low impedance (2, 4 and 8 Ohms) on any channel
-
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 to below 1 W 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
