SE-1800 Power Amplifier

This is a cost-effective product with good dynamics, excellent sound quality, light weight, small size and high power efficiency. It carries the three advanced technologies of today's power amplifiers.
1. Ultra-dynamic floating pole technology.
Ultra-dynamic floating pole technology reflects a super-dynamic power amplifier design concept.
Ordinary power amplifiers produce as much sound effects as their power. If they want to continue to increase, they are often pushed into clipping. In order to achieve higher sound effects, some power amplifiers generally achieve their goals in the form of clipping, overloading and high distortion to ensure dynamics. The DX series power amplifiers can instantly output dynamic signals that are 37% higher than the rated power, and this dynamic signal is neither clipped nor distorted. It reflects the quality of the product that is not an instrument but focuses on the characteristics of music. In layman's terms, with the same power amplifier, I am louder than you and I am not distorted.
2. Digital follow-up H-class high-speed and high-efficiency technology.
The DX series power amplifiers are different from general H-class power amplifiers. The power supply of general H-class power amplifiers is added in stages, while the DX series changes steplessly with the power supply.
The power supply of the DX series changes with the music signal in a synchronous hyperbolic manner to achieve the highest efficiency and the lowest distortion. The power supply efficiency is as high as 75%, which is power-saving and efficient, making the device load rate low and the reliability greatly improved.
3. Digital high compression ratio limiting technology.
In addition to the protection functions such as automatic temperature control and speed regulation of the fan, DC protection, and impact-free slow start-up, the DX series amplifier also has two special functions.
⑴. Full-band distortion-free digital limiting function of input signal. It can make the input signal from 0.775V-8V input, and the amplifier can output full power constantly without distortion or clipping, which greatly improves the reliability of the amplifier and protects the speaker.
⑵. Automatic temperature control and power adjustment technology.
When the DX series amplifier works at overtemperature, the digital low-frequency power limit state will appear within a certain period of time, which not only increases the reliability of the amplifier, but also prolongs the working time of the amplifier without sudden shutdown protection when working at overtemperature.
