HK-280 Audio Power Amplifier


◆ Unique four-way sound source input (with electronic switching) boot preset "channel 1"; ◆ Four microphone inputs, independent control of volume and tone (socket with DC 6V power supply and DC 48 power supply); One USB 2.4G wireless microphone input. ◆ This machine is equipped with feedback and reverberation adjustment functions, and can independently adjust the tone and volume of microphones and circuits. With RS232 interface, computer online or central control can be realized. With constant voltage broadcast signal priority playback function; ◆ A group of front-stage output and A and B groups of power output, which can drive 4 8-ohm speakers; ◆ The main function keys are of hidden design, which is inconvenient to produce misoperation and can effectively extend the service life of the sound amplification system.
