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 imported 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 imported components are equipped with SMT technology, 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, ELNA blue robe bipolar audio capacitors, imported high-frequency capacitors, etc. The sound is mellow 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 will 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
The high-voltage version only supports 8 ohms (in case of connecting 4 ohms, the power supply cannot exceed ± 80V), and the power supply range is ± 50V-± 120V; 1000W power at ± 120V, 8 ohms
