7. Total harmonic distortion : 13W / 1KHz / 12V / 4Ω - 0.5% 26W / 1KHz / 22V / 8Ω - 0.5% 35W / 1KHz / 24V / 8Ω - 10%
8. Frequency range : 10Hz-30KHz
9. Input impedance : 30KΩ
10 Output impedance : 4-8Ω
11. The voltage gain of 36dB

Second, the use precautions :
1. The power supply voltage limit 36V, do not exceed this voltage power supply, do not reverse the positive and negative
2. The power supply is recommended for 22V, 2A power supply filtering good
3. The speaker recommended 4-8 inch 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 . |
