12. Over-temperature protection: Yes, if the temperature of the radiator field-effect tube is higher than 100 ° C, turn off the output!

13. Power amplifier board size: length * width * height=98 * 43 * 30mm

matters needing attention:

1. The rated power supply voltage is dual power supply ± 70V, and the voltage can work normally at+5 — – 80V (overpressure burns out one law)

Package!), If it is Huanniu, the voltage will fluctuate with the power grid because it does not have the function of voltage stabilization. Please use the margin. electric

Do not connect the positive and negative poles of the source incorrectly to avoid burning the board

2. The power supply is recommended to be a DC dual power supply with 70V filter

3. It is recommended to use 10-18 inch 4 Euro 8 Euro speakers

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 powering on.

7. The voltage amplification factor of this board is fixed at 50 times. If the output power is not enough, add the front stage amplification according to the specific situation.

8. The board should have dual DC power supply (three lines, please Baidu if you don’t understand). Single power supply is not good! no way! no way! Supply voltage

+55V~80V, too low to work, too high to burn. The maximum effective power of the board is 500W (at+75V 4 O negative

With 1V valid value input)

9. According to the power formula P=U * U/R=voltage * voltage/load, the power is determined by voltage and load, and the voltage is high,

The smaller the load, the greater the power. The voltage supply range of the board means that the voltage boards within this range can work normally

However, not all voltage and load power are as high as the marked power output, for example, 12V power supply 4 O load,

The maximum power is 15W, and the maximum power is 7.5W at 8 O; 24V power supply 4 O, maximum power 50W, maximum power 25 O

W; At any time, the power of the power supply must be greater than the power of the power amplifier, otherwise the high volume band will not move, and the power will be reduced and

If the sound is broken, the corresponding power output cannot be reached.
