Read before Purchasing:
- Professional knowledge is highly recommended.
- Due to plagiarism by peers, all chip models on the board are polished. Please make sure that you don't mind before purchasing. Thank you!
- IC model numbers, schematic diagram and PCB file are not provided.
- Components such as capacitors may vary from batch to batch, but the performance of the components will not change. The appearance of the product is subject to the actual received goods.
Precautions (to avoid burning):
1. It is strictly forbidden to connect the positive and negative poles of power supply reversely. The board must be burned when there is reverse connection. Be careful.
2. It is strictly forbidden to wiring when it is powered on and use the board in over-voltage conditions.
Features:
- 2X600W version supports 4-8 ohms, powered by DC 12V~70V. The power is 2X600W at 70V 4 ohms and 2X300W at 8 ohms. Dimensions: 154 x 73 x 28mm/6.1 x 2.9 x 1.1" (LxWxH). Weight: 270g/0.6lb.
- The amplifier board is designed with speaker relay protection. It is instantly disconnected when it is turned off. It effectively solves the impact sound when it is powered on/off.
- Red terminals must be connected to AC 110V/220V, which supplies power to the relay. Completely isolated from the power amplifier part. Safe and secure to use.
- It is designed with imported MOSFET and Japanese all-digital chip. The chip outperforms digital chips such as TPA3255 on the market, in terms of sound quality and power. The power amp board boasts small distortion and stable and reliable performance due to imported components, SMT technology and excellent workmanship.
- The amplifier board has been repeatedly debugged by engineers for a long time. The improved HIFI class D power amp board is equipped with original tantalum capacitors for AVX, original audio capacitors for ELNA, imported high-frequency capacitors and other high-end components. Its sound is mellow and the bass is elastic and powerful. So, it is a great amplifier board for every audiophile.
Package Included:
- 1 x Amplifier Board
