HM800 Professional Power Amplifier
Features
1, 2 inches color LCD screen display with Chinese/English menu, dynamic frequency indicator.
2, Adoption of small loop negative feedback technique eliminates transient intermodulation distortion;
5, Design of common emitter common base circuit makes the frequency band of amplifier wider and more balanced, low-frequency thick and elastic, medium frequency smooth and high frequency delicate and full of sense of the level;
6, Adopt A class work mode for electric current level drive, AB class work mode for output level reduces switch distortion and crossover distortion;
7 , Adoption of electronic acceleration technology reduces switch distortion of amplifier tube to a minimum;
8, Adoption of pioneering dynamic following technology prevents the modulation of audio signals from interelectrode capacitance of transistors, and avoids power internal resistance caused by using second-level power supply for high power amplifier;
9, Using A-level iron core and oxygen-free copper paint covered wire for power transformer ensures more energy and lower operating temperature;
10, Using audio specific capacitor for power smoothing capacitor ensures less distortion and lower internal resistance, and makes charge&discharge current faster and more powerful.
11, Special boot lock function make it easy to manage and control the device.
