Product Description

The whole board with SMT machines, infrared reflow soldering, reliable, up to 93% efficiency, low power consumption, heat a small, less than 35W without heatsink.
First,the main technical parameters:
1. Supply voltage: DC 12V-24V
2. Output Power: 35W (8 ohm load 22V power supply) 18W (4Ω load 12V power supply)
3. Efficiency:> = 93%
4. Standby current: 150uA
5. Quiescent Current: 50mA
6. SNR: 89dB
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 36dB
12. The amplifier board size: LWH = 37mm * 33mm * 18mm
13. Weight: 9 g
Second, the use of note:
1. The power supply voltage limit is 36V, do not exceed this voltage, the positive and negative do not reversed
2. The power supply is recommended for 22V, 2A power supply filter better
3. The speaker recommended 4-8 inch speaker
4. Do not short-circuit the audio output to each other or shorted to ground
