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.
Power amplifier Advantage
MG+ technology has always been recognized, and customers want products like MG+ that help save energy and improve sound quality.
1. Stable performance
2. Highest power density
3. The lightest weight
4. Greater reliability
5. Reduce the load on the circuit components by providing a properly adjusted DC power supply
6. Higher performance
7. Lower distribution requirements to reduce copper loss in electricity
8. Significantly reduce the amount of power required
9. Great savings on energy costs
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.
