Multichannel Digital Power Amplifier

Compact, portable, lightweight and beautiful design, 2 to 4 channel power amplifier adopts 1U chassis, 6 to 8 channel power amplifier adopts 2U chassis. The front panel has a power switch, a separate channel gain control knob, and an LED status indicator. The rear panel has XLR balanced audio input and loop output. It is equipped with an NL4MP speakon speaker interface, with stereo, parallel, and bridge mode selection functions. Using high-power, low-noise Class D amplifier circuit and integrated switching power supply, the human voice is transparent and the performance is stable. Support 4/8 ohm constant resistance output, support 70-100V constant voltage output (GX- PA3001). With an efficient air duct design and a variable speed cooling system, the whole machine has a good heat dissipation effect and extremely low working noise. With high-quality components and strict quality management, it can protect the circuits effectively, making more stable.
