ROOMXS 4 Channel Series

● MG+ ROOM XS series are 2-channel and 4-channel high-fidelity high-power stereo output D class, environment-friendly and energy-saving amplifiers.
When this series with 200 w / 300 w / 400 w / 550 w / 700 w / 850 w / 1000 w / 1300 w/two channel power output of 1500 w and 200 w / 300 w / 400 w / 600 w / 800 w / 1000 w four-channel power output models.
● The MG+ ROOM XS series adopts the latest Class D amplifier technology to provide smooth and flexible handling while maintaining the integrity of MG+ excellent sound quality at high power output.
MG+ has always been concerned about energy conservation. Since the company was born, it has been using power factor correction technology to improve the performance of power amplifier and reduce the consumption of power supply current. The past year has seen a greater global awareness of the importance of energy. In addition to blackouts in the United States and Europe, skyrocketing oil prices, rising energy demand in developed countries like China, and global warming have created a growing interest in energy conservation. The performance industry has always been sensitive to environmental issues. In the past year, many artists have begun promoting their Tours as "green" shows, using alternative energy or planting trees to compensate for the local impact of the carbon dioxide emitted by each concert.

10. Reduce heat dissipation requirements in fixed installations

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 ROOM XS 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 2U solid shell for professional KTV, theater and live performance amplifiers.

The MG+ amplifier's well-known reliability comes with a three-year warranty from the date of your first purchase.

Class D rear pole output plus analog transformer power supply:
1. Use 20% less energy;
2. Reduce the size of the power amplifier;
3. Reduce the cross-section size of the cable, because the RMS current is less in use;
4. Make the cable transmit smaller because the harmonic of the power frequency is lower. This can reduce the noise and distortion caused by fluctuating power supply.
5. Realize full power output, ultra-long standby, and reduce electromagnetic interference to the power supply by batch installation;
6. The power supply stability is highly indicated, and it can work in harsh environment without external influence.
7. Wide voltage input range: AC AC165V-265V works normally.
8. Advanced protection functions: soft start of power on, DC output protection (power amplifier self-destruct will not damage the speaker), internal automatic voltage limit, short circuit protection can be checked with or without signal output.
9. The sound sounds clear and accurate. Because it USES no negative feedback 16 amplifier circuit and digital filter and other advanced processing technology.
10. Without zero crossing and cross crossing distortion, traditional amplifiers are usually used because of the zero crossing distortion and cross crossing distortion caused by the piping pairing process and each power level adjustment process.
