1: Main input voltage AC/190V-240V

2: Damping coefficient at 8 Ω: > 400

3: Frequency response 20HZ-20KHZ ± 0.3dB

4: Total harmonic distortion<0.03%;

5: Signal to noise ratio>102dB;

6: Channel separation (crosstalk) at 1KHz>100dB, 8 Ω

7: Protection functions: startup buffer, overcurrent protection, short circuit protection, over temperature protection, output DC protection, etc

8: Number of fans: 2, which better helps the power amplifier dissipate heat and has strong stability

9: Purpose: 200W to 400W suitable for various conferences, small indoor and home KTVs; 500W to 800W suitable for various medium-sized performances and KTVs; 10: Line level: 200W -400W: Class AB; Above 500W: Class H. 11: This series is equipped with an LCD display screen, which can display the input voltage of the power amplifier; Signal input level; The speed of the fan and the temperature of the amplifier can not only increase the aesthetics of the amplifier, but also greatly improve the stability of the amplifier by viewing its working status through its LCD display screen
