LAB GRUPPEN E E 2:2 เครื่องขยายเสียง 2 แชนแนล 1,200 วัตต์

• 1,200 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 600 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
• 10-Year Warranty Program*
• Designed and engineered in Sweden
