HiFi Mono 1500W 12-110V Power Supply Stereo High Power Class D Digital Audio Power Amplifier Board

HiFi Mono 1500W 12-110V Power Supply Stereo High Power Class D Digital Audio Power Amplifier Board

Precautions:
- The amplifier board must be connected to AC 220V to use, and the battery cannot be used.
- It is strictly prohibited to connect the positive and negative poles of the power supply in reverse. Connecting them in reverse will result in burning, so be sure to pay attention.
- It is strictly prohibited to use power on wiring and over voltage power amplifiers. Equipped with horn relay protection, power on delay, and instant shutdown, effectively solving the impact sound of power on/off. The red terminal is connected to 110V/220V AC to supply power to the relay and must be connected. It does not work without connection (completely isolated from the power amplifier for safe and reliable use); The board is powered by a single DC power supply of 12-110V (there may be slight differences in capacitors and other components from different batches, please refer to the actual product, performance remains unchanged)

Differences:
- There are two types of power amplifiers: 1000W and 1500W. The board size is the same, but the tube model, capacitor, and inductor are different. You can purchase according to your own needs.
- 1000W: supports 4-8ohms, with a power supply range of DC 12V ~ 90V. The power output is 1000W at 90V 4ohms and 500W at 8ohms; Size: 154 x 73 x 28mm, Weight: 226g.
- 1500W: supports 4-8ohms, with a power supply range of DC 12V ~ 110V. The power output is 1500W at 110V 4ohms and 750W at 8ohms; Size: 154 x 73 x 28mm, Weight: 260g.

Features:
- The higher the supply voltage, the greater the power, and vice versa. The 12V supply has the lowest power.
- Designed with imported transistors for MOS and all digital chips of Japanese, the sound quality and power far exceed those of digital chips such as TPA3255 on the market. All imported components are processed with SMT technology, resulting in excellent workmanship, minimal distortion, stable and reliable performance
- After long-term and repeated debugging by engineers, this amplifier has been improved and developed into a HIFI level D-class amplifier board. The entire board is equipped with high-end components such as tantalum capacitors for AVX, blue robe infinite audio capacitors for ELNA, and imported high-frequency capacitors. The sound is rich and the bass elasticity is strong, making it a must-have for every audiophile.

Package Included:
- 1 x Power Amplifier Board
