Description:
    Note: This board is lithic for the finished board. Please purchase two pieces for the two channels. The whole machine is reflow soldered with a beautiful layout. All the materials are full and the sound quality is super good!

    Tips: The default power supply voltage of this power amplifier board is ±60---±85V for dual DC power supply. The lower the voltage, the smaller the output power.
     
Specifications:
    1. Rated power supply voltage: dual DC power supply ± 80V
    2. Maximum rated output power: 1700W (±80V power supply 2 ohm load, distortion 10%)
    3. Efficiency: >=90%
    4. Signal to noise ratio: 90dB
    5. Total harmonic distortion: 1600W (±80V power supply 2 ohm speakers, distortion <1%)
                          800W (±80V power supply 4 ohm speakers, distortion <1%)
    6. Frequency response range: 20Hz-22KHz
    7. Speaker: 2-4Ω, pay special attention, if you need to get high power, please use 2 ohm speakers or use 2 4 ohm speakers in parallel. If you use 4 ohm speakers, the power is reduced by half and the maximum is 800W.

    8. Voltage amplification: 50 times
    9. Input sensitivity 1.2V (RMS)
    10. Output short circuit protection: Yes
    11. Output DC bias protection is speaker protection: Yes
    12. Over-temperature protection: Yes, the temperature of the radiator FET is higher than 100 °C, and the output is turned off!
    13. Power amplifier board size: length x width x height = 116x50x85mm
    14. Weight: 350 grams

The use of precautions:
    1. The rated power supply voltage is ±80V for dual power supply, and the voltage can work normally at ±60---±85V. (If it is a power frequency transformer, please leave a margin when the voltage fluctuates. The power supply is 3 power supply lines, positive and negative power supply. Do not pick up the wrong to avoid burning the board
    2. Power supply is recommended for DC dual power supply ±80V filter better power supply
    3. Speaker recommended 10-25 inch 2 ohm-4 ohm speaker
    4. Although the audio output has short circuit protection, try not to short circuit.
    5. Please check carefully before powering on, to ensure that the wiring is correct before power can be applied.
    7. The voltage amplification factor of this board is fixed at 50 times. If the output power is not enough, add the preamplifier according to the specific situation.
