Frequency range: 20Hz-20KHz
Input impedance: 30KΩ
Speaker: 4-8Ω
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.

2014 new, enthusiast LM1036 + TPA3116 one-2 * 50W Class D digital amplifier board
Nichicon capacitors two large high-frequency low-impedance HV series provides a steady flow of energy. Audio input for Philips CBB capacitors do little good signal coupling loss!
Audio output filter selection of Taiwan’s imports of high-current power inductors with Thomson CBB capacitor filter, low loss and distortion!
