High power 500W instead of IRS2092S D class HIFI digital workplace/finished product/single channel/super lm38

According to the power formula p = u/r = voltage*voltage/load, the power is determined by voltage and load. The voltage is high, the load is small, and the more the power is.It can work normally, not all voltage and load power are labeled as high -power output. For example, 12V power supply is 4 Euro load, the power is maximum of 15W, and the power is 7.5W at 8 Euros; 24V power supply is 4 Euros, the power is 50W, 8 Euros, 8 Euros, 8 Euros, 8 Euros, 8 euros.The maximum is 25W; at any time, the power power must be greater than the power of the amplifier, otherwise the large volume will not move, the power will be reduced and sound, and the corresponding power output will not be achieved.1. Power supply voltage: dual-DC power supply ± 58 --- ± 70V

2. Rating output power: 500W (± 65V power supply 4 Euros load, 10%distortion)
3.效 率：>= 90%
4. Signal and noise ratio: 90db
5. Total harmonic distortion: 380W (± 65 power supply 4 Euro speakers, distortion 280W (± 65 power supply 8 Euro speakers, distortion 6. Frequent sound range: 20Hz-20kHz
7. Speaker: 4-8Ω
8. Voltage amplification multiple: 36 times

9. Input sensitivity 1.5V (RMS)
10. Short -circuit protection: Yes, yes
11. Output DC partial pressure protection is speaker protection: Yes, yes
12. Over -temperature protection: Yes, the temperature of the radiator field effect tube is higher than 100 ° C, turn off the output!Second, precautions:

1. The rated power supply voltage is a dual power supply ± 65V, and the voltage can work normally at ± 58 --- ± 70V (more than 70V, must be burned, burned and burn it, it will not be included!), If it is a ring cattle, it does not have the voltage voltage function because it does not have the voltage function.The voltage will fluctuate with the grid, please use the remaining amount.Do not connect the positive and negative electrode of the power supply to avoid burning the board
2. Power supply power supply is recommended as DC dual power supply ± 65V filtering power supply power supply
3. The speaker is recommended to use 10-18-inch 4 Euros-8 Euro speakers
4. Although the audio output has short circuit protection, try not to be short -circuited
5. Please check carefully before powering to ensure that the wiring is correct before power on.
7. The large multiples of this board are fixed to 40 times. If the output power is not enough, it will increase the front stage to magnify it by itself.
