Special reminder:
1. This board is a full-frequency pure final stage power amplifier. To be used as a subwoofer, a pre-stage low-pass filter is required.
2. The board is powered by dual DC voltage, the car battery can not be used as a single power supply, and the car power amplifier boost power supply is required.
Designed by IRRP4227 and IRS2092S of American IR, the rated effective power is 1000W. It can push all the power horns of 2-8 Euro on the market, on-board intelligent temperature control fan, which can not only save heat but also reduce noise. All imported components plus SMT process, excellent workmanship, low distortion, stable and reliable performance
This board is mono channel finished board. If you need two channels, please buy two pieces.
The default supply voltage is ±58---±85V for dual DC power supply.
The lower the voltage, the lower the output power.
Parameters:
1. Supply voltage: dual DC power supply ± 58 --- 85V
2. Maximum rated output power: 1000W (±85V power supply 4 ohm, distortion 1%)
3. Efficiency: >=90%
4. Signal to noise ratio: 90dB
5. Total harmonic distortion: 1000W (±85 powered 4 ohm speaker, distortion <1%)
500W (±85 powered 8 ohm speaker, distortion <1%)
6. Frequency response range: 20Hz-22KHz
7.Speaker: 2-8Ω , pay special attention if the power supply with 2Ω low impedance speaker is less than ±65V
8. Voltage magnification: 36 times
9. Input sensitivity 1.5V (RMS)
10. Output short circuit protection: Yes
11. Output DC bias protection that is horn protection: Yes
12. Over temperature protection: Yes, radiator FET temperature is higher than 100°C, turn off output
13. Power amplifier board size: length x width x height = 132x68x45mm
14. Weight: 260 g
Attention:
1. The rated power supply voltage is ±75V for dual power supply, and the voltage can work normally within ±58---±85V (If it is a power frequency transformer, the voltage fluctuates, please leave a margin, the power supply is 3 power supply lines, and the power supply is positive and negative Do not take wrong so as not to burn the board)
2. The recommended power supply for DC dual power ±75V filtered power supply
3. Speakers recommended with 10-25 inch 2-8 Ω speaker
4. Although the audio output has short circuit protection, but try not to short circuit
5. Please check carefully before turning on the power to ensure that the wiring is correct before power is applied.
7. The voltage magnification of this board is fixed at 40 times. If the output power is not enough, the preamplifier will be added according to the actual situation.
Package include:

The picture shows the wiring diagram.
The board is powered by dual power supply. The audio input is 3 feet, the middle is the ground line, and the two sides are connected together.
If it is not the switching power supply, use with ring cattle needs to add rectification and filtering circuit
If your switching power supply is not dual output but single output, you need two single power supplies in series.
