The E Series, Lab.gruppen engineers drew upon the cutting-edge amplifier design philosophies developed for the flagship PLM & trade; 20000Q Powered Loudspeaker Management system, evolving these to create new circuit topologies and control features to meet the demands of 21st century AV installations. The result is a new amplifier platform called IDEEA: IntelliDrive Energy Efficient Amplifier. The principal design challenge was maintaining Lab.gruppen & rsquo;s impeccable sonic performance and robust power output while meeting & ndash; or exceeding & ndash; the rigorous efficiency requirements of Energy Star 2.1 certification. The challenge was met on two fronts: reducing current draw during operating cycles with vigorous program material and high output levels, and reducing power consumption during non-operational cycles.
1,000 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 with Energy Star* certification for supreme green credentials and exceptionally low lifetime running costs
Flexible IntelliDrive permits delivering the 4 x 250 W at constant voltage 70 V or low impedance (2, 4, 8 and 16 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 & rsquo; 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 fans 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
