DA4750 Professional Power Ampifier

Description of products

1. DA4750 professional Power Amplifier，adopt excellent circuit design.，can satisfy most of the needs of expanding sound.
2. Efficient and stable power output, ultralight design，suitable for installation in any performance environment
3. DA4750 initiated 1U rack space design，working mode: class D，single channel power output is 750W 4Ohm；bridge power output is 1500W 8Ohm；DA4750 provide the optimal power distribution through continuous monitoring signal and maximum efficiency. This smart distribution eliminates excess heat or energy waste.it also with low noise fan,has persistent cold air can ensure good heat dissipation for high power supply transformer.
4. DA power amplifier has fashionable and avant-garde sag design for front panel.10dB LED peak signal Indicator amplifier rear panel balance XLR signal input port, output port ensure the socket. 2 modes selection switch allow stereo and monobridge mode voice wasily switch.
5. DA4750 design feature：High efficiency, high performance, more complete and lightweight design，provided professional sound amplification solutions for music fans of music venues, churches, fitness clubs and mobile DJS, outdoor parties, and travelers.
