★ power amplifier
◆ uses advanced and high-efficiency power amplification circuit, sufficient power output, simple and beautiful process;
◆ built-in MP3 decoding playback module, support U disk and TF card access playback, distribution of infrared remote control, easy to operate;
◆ supports mobile Bluetooth connection, can be on demand through mobile phone player;
◆ is equipped with 2-channel microphone input (input sensitivity with 10mv and 250mv for selecting applications);
◆ is equipped with 2 AUX line input, 1 EMG emergency input and 1 auxiliary output;
◆Power output is equipped with 70V / 100V fixed voltage output, and 4-16 Ω fixed resistance output, the output effective power is 250W;
◆ output frequency sound range is 100~16KHz;
◆ each signal input is equipped with an independent volume control (except for EMG signal input), with high and low sound and total volume adjustment;
◆ has level 3 priority functions, EMG is the highest priority, followed by microphone 1 (MIC1) as level 2 priority, level 3 is AUX1, AUX2, MIC2;
◆ equipment is equipped with abnormal work protection warning function. When the input signal is too large, too heavy load, too high temperature, and the line is short circuit, the corresponding indicator light prompts, with extremely high reliability.
◆ 2U standard chassis design, aluminum alloy panel, beautiful and practical. Box size: 485 * 88 * 340mm
★ Outdoor Waterproof Speaker
◆ all-weather sound column, the shell is made of aluminum and magnesium alloy, the overall design is generous, suitable for a variety of indoor and outdoor occasions;
◆ sound column box shell is made of strong aluminum and magnesium alloy material, integrated die-casting, angular, strong three-dimensional sense;
◆ hanging edge rubber edge to improve the tension, improve the speaker medium and high audio effect, make the medium and high audio more clear and transparent, high, and durable;
◆ metal mesh cover using Aksu spraying technology, not easy to rust, effectively prevent dust, can keep the horn used in a wet environment for more than 5 years;
◆ horn unit drum paper using waterproof coating technology, water droplets on the drum paper will not be wet, directly slide;
◆ built-in copper transformer, E-shaped silicon copper sheet, can ensure the full power of the speaker, produce better sound effect, long sound transmission distance, small audio distortion;
◆ shell: 4mm ultra-thick aluminum magnesium alloy shell, the upper and lower cover is also all aluminum magnesium alloy;
