Meyer Sound Professional Active Speakers Analysis

1. built-in compression limiter

The built-in compression limiter of Meyer Sound speakers greatly reduces the possibility of damage due to overload and saves users a lot of trouble. For the general loudspeaker system's compression limiter, many of the tuners are not properly mastered. It is often adjusted by experience. Due to the incorrect selection of the parameters of the compression limiter, it causes many problems, not only can not protect the sound box and the function of the amplifier, but also may introduce greater distortion. For example, the selection of the threshold is too large. It can not start the compressor in time to burn down the sound box or amplifier; the threshold is too small to start the compressor early and introduce the distortion to change the sound quality and tone of the original sound source.

2. use "Tru Power" protection technology

All Meyer Sound speakers use the "Tru Power" limiting circuit to protect the loudspeaker drive unit and monitor the output power of the loudspeaker in real time. This technique makes the loudspeaker have higher sound pressure and increase the available allowance, and the power compression of the speaker is still smaller than that of 1dB for a long time, while the general loudspeaker system is working. The rate compression is 3 to 6dB.

3. built-in parametric equalizer

The Meyer Sound box has a built-in parametric equalizer, which makes the sound box in the frequency response smooth, without any excesses or trapping points, greatly reducing the formation of feedback and improving the sound gain of the system, which provides great convenience for the adjustment of the system's room balance.

4. using phase correction technique

Meyer Sound's speakers use phase correction technology, which is another patent technology of Meyer Sound. So that the response of the speakers in the working frequency is also quite consistent, that is to say, the signal in each frequency band of the sound reaches the human ear at the same time. The human ear is sensitive to the time difference of arrival. The phase correction technique of Meyer Sound solves this problem well.

5. built in amplifier

The built-in amplifier of the MeyerSound sound box not only saves a large number of sound box wire. It is easy to install, but also reduces the transmission loss of the signal, at the same time, it improves the effective damping coefficient of the amplifier. Because the distance between the power amplifier and the loudspeaker drive unit is very short, the resistance between them is also very small, the damping coefficient of the amplifier is fully played, and the transient distortion is reduced effectively. Moreover, the power amplifier and the power matching of the loudspeaker, the sensitivity matching and the selection of the frequency separation point are eliminated.

6. intelligent power supply system

The intelligent AC power supply system provides automatic wide voltage selection (voltage stabilizing power), the operating voltage range is 85-134V and 165-264V, and it has the functions of electromagnetic interference filtering, soft start current connection and surge current suppression.

7. high voltage and high power drive unit

Adding magnetic fluid to the sound ring of the high bass unit can effectively reduce the damping of the sound circle and reduce the temperature of the sound ring, and improve the sensitivity of the horn unit for the high sound pressure, and provide a powerful guarantee for the high power output.

8. omni-directional solutions

Meyer Sound, in order to better restore sound, has been working to design and create a full range of components to build a comprehensive, superior performance system and provide an integrated solution. Every sound box is built in the power amplifier, processor, and horn unit, not only to save time, storage space, and transport labor costs, but also to restore the perfect sound without debugging and the division of labor.

The operation is done by Meyer sound plant, such as the adjustment of the compression limiter, the power matching of the amplifier and the loudspeaker, the matching of the sensitivity, the selection of the frequency divider and so on.

This question can be answered in two respects.

Meyer Sound speaker built-in compression limiting circuit and Tru Power protection circuit, power amplifier and loudspeaker in the best matching state.

The possibility of damaging the power amplifier or speaker unit is very small.

Even if it is damaged, it is convenient to repair. The Meyer Sound speaker is modular design, and the module can be replaced during maintenance. Like

It is as convenient to replace a sound card and a video card in a computer

Answer: all products of Meyer Sound conform to the US UL certification and European CE certification. They have safety indicators for fire prevention and electric shock.

Strict regulations have met or even exceeded the requirements of fire fighting.

Answer: Meyer Sound's power amplifier and processing circuit all use resistor capacitance components and transistor devices, without electron tube components, and mechanical.

Vibration can not fundamentally modulate the motion of electrons, and there is no modulation distortion introduced.

Answer: Although the amplifier of Meyer Sound is in the sound box, it has installed a radiator fan or cooling plate outside the speaker box, which does not affect the amplifier.

Normal heat dissipation.

MILOTM: high energy curve array

MILO is a 4 frequency division system with a power amplifier designed for vertical arrays. It has enough sound pressure level (140 dB sound pressure level @1 meters) for high level large stadiums and stadiums. Compared with some passive line array systems, MILO is small in size, light in weight, and can output more power. Although the length and height of MILO are smaller than that of M3DTM, its width is the same as that of M3D, which makes it perfectly integrated with M3D or M3D. The array of ultra low MILO and M3D shows the advantages of Meyer Sound low frequency directional control, and the system designers can effectively avoid projecting ultra low energy into the area behind the array.

The middle and low frequency part is composed of two 12 inch neodymium magnet drives, which are divided into two ways: two units are driven at the same time under 300Hz, and the frequency divider is used to make one of the two drives, thus ensuring the optimization of the polarity and frequency response characteristics. The medium and high frequency part (650Hz to 4kHz) uses a 1.5 inch exit, a 4 inch diaphragm compression driver, and 900 constant points through the Meyer Sound patented product REMTM (banded simulation compound sound hole).
