POWERMINI4 channel power amplifier

The POWERMINI family is a series of 2 channel and 4 channel high output power amplifiers.

The series offers 400W/600W/800W/1000W two-channel power output and 200W/400W/600W/800W four-channel power output models.
MG + adopted the latest class D power amplifier technology, when large power output, smooth and flexible manipulation, while maintaining the integrity of MG + excellent sound quality, all models benefit from new developments of MG + switch power supply technology, this technology makes high power portable parts, under the condition of simple can implement all professional application.
MG+ 's newly introduced POWERMINI series is designed to deliver simple, pure, reliable power for applications, and its ease of use is Paramount without losing sound integrity.

MG+ emphasizes a direct approach to market demand. Key factors such as power output, loading, flexibility and connectivity of AC power supply. Its smooth and outstanding power output spans four channels and is designed in a 1U rugged enclosure for professional equipment, theater and performance sound amplification applications.



Efficient output /Efficient output

Class D - PWM (pulse width modulation) efficient output stage
This technology was introduced by Powersoft in 1995 and has been increasingly adopted by manufacturers and end users. A key part of the technology is based on ultra-high performance, converting all the power in the power supply to usable power and recycling reactive power back from the speakers (which is generally harmful for traditional linear amplifiers). Devices using this technology provide very useful features for touring and fixed installation applications.
MG+ emphasizes a direct approach to market demand. In the introduction of the identified POWERMINI series, key performance such as power output, loading, ac power supply flexibility and connectivity. Its smooth and outstanding power output spans four channels and is designed in a 1U rugged enclosure for professional equipment, theater and performance sound amplification applications.
MG+ amplifier known for its reliability is guaranteed for 3 years from the date of your first purchase.


Mg + technology has always been recognized, and many competitors regard power factor correction as cutting-edge technology. What customers need is products like Mg +, which can help save energy and improve sound quality. The following summarizes the advantages of power amplifiers using power factor correction technology:
1. Stable performance, not limited by power supply (especially useful in countries with power quality lower than standard)
2. Highest power density
3. Lightest weight
4. Higher reliability
5. Reduce the load of circuit components by providing adjusted DC power supply
6. Global operation from (165 to 265 VAC, 50 / 60 Hz)
7. Higher efficiency
8. Lower distribution requirements and reduce copper loss in power
9. Greatly reduce the required power capacity
10. Great energy saving
11. Reduce heat dissipation requirements in fixed installation
