Product model: ABS-120M/180M/280M/380M/500M/650M Actual power: 120W/180W/280W/380W/500W/650W Integrated power amplifier with playback and display functions such as MP3, FM, recording, Bluetooth, and large remote control. Adopt advanced high-efficiency power amplifier circuit, with 3 microphone inputs, 2 line inputs, 1 auxiliary output, The voltage output is 70V/100V, the constant resistance output is 4-16Ω, and the output frequency response range is 20-20KHz; Each input volume can be controlled independently, with high and low volume adjustment; microphone 1 is set as the highest priority function, automatically suppressing other input signals; The equipment is equipped with abnormal working protection and warning function. When the input signal is too large, the load is too high, the temperature is too high, the line is short-circuited, etc., the abnormal working protection and warning function of the machine. Sex. 2U standard chassis design, luxurious aluminum alloy panel, beautiful and generous. Practical power, stable and durable. Size below 380W: 485*390*90MM, size above 500W: 485*458*90MM. Range of application: Where combined constant voltage power amplifiers (power amplifiers) are needed, such as schools, shopping malls, specialty stores, restaurants, etc. 240V output can be customized according to customer requirements and OEM products can be provided (There are also a variety of U disk partitioned independent tuning power amplifiers and audio-visual platform power amplifiers optional)
