<ul><li>1. Adopt original imported TPA3255 chip 
2. The main filter electrolytic capacitor adopts a capacity of 470UF / 50V x 4, which ensures a strong source of continuous power support. 
3. The resistor uses high-precision chip resistors to ensure a good signal-to-noise ratio. 
4. Adopt special inductance for audio to ensure the sound is crisp and powerful. 
5.PCB adopts 1.6mm thick double-sided board, 2.0 ounce copper thickness, and full tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality. 
Descriptions: 
TPA3255 Four-channel digital Class D amplifier board 
TPA3255 is a high-performance Class D power amplifier, which has Class D efficiency and can bring true high-end sound quality. There is an advanced integrated feedback design and a proprietary high-speed gate driver error correction function. This technology allows the device to maintain ultra-low distortion throughout the entire audio frequency band while exhibiting perfect sound quality. 
Basic performance parameters: 
Working method: Class D 
Quiescent current: 150mA 
Work efficiency:. Greater than 90% 
Output Power: 
315W / 4Ω, distortion 10% x 4 
185W / 8Ω, distortion 10% x 4 
260W / 4Ω, distortion 1% x 4 
150W / 8Ω, distortion 1% x 4 
Frequency response: 20Hz to 20KHz 
Dynamic range: Greater than 100 dB 
Signal to noise ratio: (SNR) Greater than 111dB 
Working voltage: DC24-48V switching power supply (DC) (It is recommended to use DC36V switching power supply. If the temperature of the radiator of the power amplifier board with DC48V power supply will be higher, you need to increase the fan cooling) 
Material:ABS 
colour:As Shown 
Package Contents: 
1 x Power Amplifier
