Features:

1.AF series power amplifiers, bringing together new generation products of class AB core technology, imagine the world.

2. Adopt small loop negative feedback technology to eliminate transient intermodulation distortion.

3. Adopt common-spoke common-base circuit design to make the frequency band of the power amplifier wider and more balanced, the low frequency is thick and flexible, and the intermediate frequency is bright and delicate and full of layering.

4. The power stage promotes the use of class A working mode, and the output stage adopts class AB working mode to reduce the switching distortion and crossover distortion; the use of electronic acceleration technology minimizes the switching distortion of the power amplifier tube.

5. The first dynamic follow-up technology, which eliminates the modulation of the audio signal by the inter-electrode capacitance of the transistor, and solves the internal resistance of the power supply caused by the secondary power supply that the high-power amplifier must use.

6. The power transformer adopts A-class iron core to make the energy more sufficient and the working temperature lower.

7. The power filter capacitor uses audio-specific capacitors with less distortion, lower internal resistance, and faster and stronger charging and discharging currents. 1000U / 1300 with gold panel 3U and other with black panel 2U.

8. Applicable places: volume-amplified KTV, night clubs, private clubs, multi-function halls, home entertainment KTV, meeting rooms and other sound reinforcement places.
