Supply voltage: DC 12V-22V
Maximum output power: 2X50W (4 ohm load 21V supply) 2X30W (8 load 24V supply)
Efficiency: > = 90%
The signal to noise ratio: 100dB
Total harmonic distortion: (50W / 1KHz / 24V / 4 - 0.1 %) (30W / 1KHz / 24V / 8 - 0.1 %)
Frequency range: 20Hz-20KHz
Input impedance: 30K
Speaker: 4-8 The voltage gain of 26dB
The amplifier board size: LWH = 86mm * 62mm * 18mm (size excluding potentiometer handle protruding parts) potentiometer center distance: 28mm
Weight: 85 grams
Caution:
1. The power supply voltage limit 24V, do not exceed! Otherwise capacitance easy exploding with rectified AC voltage peaks do not exceed 25V. Do not exceed this voltage power supply, do not reverse the positive and negative
2. The power supply is recommended for 22V, 4A power supply is better than filtering
3. Recommended by 4-6 inch speaker 4 ohm or 8 ohm speaker
4. Do not short-circuit the audio output is shorted to ground or to each other Please check carefully before 5. energized, make sure the wiring is correct after only pass.
