LAB GRUPPEN E 5:4 เครื่องขยายเสียง 4 แชนแนล 500 วัตต์

• 500 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 125 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
• 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
• 10-Year Warranty Program*
• Designed and engineered in Sweden
