IRAUD350 IRS2092 Class D AMP board Assembled 350W 8ohm Mono Audio Power

Product details:
Using original IRS2092 and IRFB23N20D.
The main filtering capacitor has a capacity of 4700UF/80V * 4 and adopts a dual rectifier 25 * 2 (50A) flat bridge to ensure strong and continuous power support.
The main circuit uses resistors with an accuracy of ± 1%, ensuring a good signal-to-noise ratio for the entire machine.
The PCB adopts 1.6mm thick double-sided board, 2.0A copper thickness, and full tin spraying process to ensure good passing performance of large and small currents.
Adopting a 20A high current shielded inductor to ensure crisp and powerful sound.
Board Size:178*76*49mm

1. Voltage range: AC dual 20V-45V (rectified voltage ± 28V-60V). Note that when the voltage is below AC 35V, R6 R7 should use a 2K Ω/2W resistor instead. (The default voltage for shipment is 40-45V, and R6 R7 is 3.9K)

2. Output power: 350W/8 Ω AC dual 50V power supply, distortion<0.1%; 700W/4 Ω AC dual 50V power supply, distortion<0.1%

3. Voltage amplification factor: 36 times (positive phase amplification)

4. Input sensitivity: 1.6V (effective value)

5. Input impedance: 14K Ω

6. Frequency response: 0-50KHz ± 1dB 10W/8 Ω

7. Remaining noise voltage: 200uV

8. Dynamic range:>100dB
