Mono Channel Digital Class D Stage Subwoofer Power Amplifier Board-A

Mono Channel Digital Class D Stage Subwoofer Power Amplifier Board-A Description

New upgrade, circuit optimization, added horn relay protection, delayed startup, and instant shutdown, effectively solving the impact sound of switch on/off. Equipped with relay power supply, external 110V/220V AC can be used (completely isolated from the power amplifier for safe and reliable use)
Designed using MOS transistors and Japanese fully digital chips, with a rated effective power of 1000 W, it is not a problem to promote all power speakers of 4-8 ohms on the market. All components are equipped with , with excellent workmanship, small distortion, and stable and reliable performance.
This HIFI digital power amplifier has been repeatedly debugged and improved by engineers for a long time to develop a 1000W HIFI D-class power amplifier board. The entire board is paired with high-end components such as AVX tantalum capacitors, blue robe bipolar audio capacitors, high-frequency capacitors, etc. The sound is and the bass elasticity is strong, making it a must-have product for every HiFi enthusiast.

Precautions for using the board to avoid burning:
1. There is no wiring or touch the audio input terminal when powered on.
2. Try not to empty the output as much as possible.
3. It should be used under the specified load and voltage
There may be differences in capacitors and other components from different batches, please refer to the actual product, and the performance not change.
The low-voltage version supports 4-8 ohms, with a power supply range of 50V- 80V, and a power of 1000W at 80V 4 ohms and 500W at 8 ohms
