Description

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’ 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
