Conference microphone is a real helper today, without which it is impossible to organize any event. Because the presence of sound equipment affects the success of the whole event. With the help of such a simple device, everyone present will be heard. Especially since today, you can find great conference mics for every taste and budget. In addition, it is possible to speak and discuss various topics without getting out of place.
Conference Microphone Features
As a rule, no meeting involving large numbers of people cannot do without microphones for conferences. This device makes it possible to hear everyone correctly, without distorting the main idea. In addition, this device not only cuts off unnecessary noise but also has additional functions:
- an activation button;
- the earphone jack;
- automatic shutdown system.
Wireless runs on batteries, the desktop has a control console, omnidirectional can capture sounds within a radius of 360 degrees.
The size of the room matters
When choosing sound equipment, the room is of particular importance. It can be a small meeting room, which can accommodate up to 6 people. The main feature of such offices is a small area, a lot of furniture, low ceilings, a small echo. In these rooms, a microphone is located close to the participants. For such space, the best option is an omnidirectional device installed in the center of the table to receive a signal from all participants.
For the standard sizes of conference rooms, designed for up to 20 participants, microphones with a large coverage are required. Also, the ability to connect the necessary equipment is an important feature. The main problem with such rooms is their size. It causes great acoustic disturbances (air conditioning system, noise, large echoes, ventilation holes).
The difficulty is that in such offices it becomes almost impossible to control independent echo cancellation and to control each microphone. The best option is an omnidirectional microphone array in the ceiling. Or (depending on the number of speakers) desktop devices. Their advantage is the ability to recognize sound zones independently.
The problem with huge meeting rooms is that they are unable to reproduce quality sound because of the large area. Conference systems are ideal for this type of room. They not only provide good sound but also create complete clarity of speech of the speaker. Additional systems can be hinged or suspended microphones.
Mobile conference rooms, halls-transformers. We mean halls where it is easy to rearrange furniture and equipment, or divide halls with the help of mobile partitions for specific events. This type of conference hall is most often found in hotels and business complexes. The room-transformer almost does not reflect the sound. It also has a minimum level of noise, due to special partitions, acoustic ceiling, and carpeting.
The main task is to achieve good sound for unevenly built structures in the multifunctional hall. At the same time, providing sufficient volume for all participants to hear the conversation. A mandatory criterion for microphones (for ease of movement) – wireless configuration. Wireless conference systems make your equipment mobile and reduce the time it takes to move it.
High-quality mic holders are no less important and ensure 100% microphone performance. The choice is quite huge. They differ in quality of material, construction, method of fixation and type of destination. Each mount has its specific and universal purpose. The sound device can be used for one person or group, to stand on a table or a podium.
The most popular and practical mounts are universal. They are widely used in recording studios, press conferences, debates, speeches, videoconferences, programs, blogs and so on. There are no difficulties in using such mountings. It is enough to install the microphone on the table. The module is firmly fixed, and there is no risk that the equipment will fall down. In addition, such mounts are equipped with an anti-vibration function that can completely eliminate this defect, making your voice clear.
A clothespin is another universal mount. Its convenience is a special gooseneck, which provides stability not only in any position but also on any surface. The mechanism of attachment for small microphones gives more freedom of movement to participants.
The same independence is provided by the head holders. They release the speaker’s hands if there is a need to present an item, or just to facilitate a conversation with those present at the conference.
Criteria Of Choice
Sound equipment occupies a special place when conducting videoconferences, negotiations, meetings, and speeches. Because all participants in the event should hear each other clearly. Speaking specifically about conferences, clarity of speech is of particular importance. It should be clear to everyone present. With the distortion and “blurring” of words, negotiations turn out to be ineffective, and many inaccuracies and errors arise.
When choosing, you should rely on 4 main components.
- Frequency range. With its help, high and low-frequency transmission limits are determined. The necessary indicators are determined for a specific room, taking into account by whom, how and for what the microphone will be used next.
- Orientation (determines location). Most often, the criterion is used when the hall is large and there are many participants in the event. According to the type of directivity, they are distinguished: omnidirectional, bidirectional (the microphone receives sound only from 2 sides), unidirectional (the audio equipment catches sound only from the front).
- Sensitivity to the perception of barely audible sounds. The indicator is determined in decibels and depends on the purpose of the unit. At a high level, excessive noise will be heard. At a low level – only loud tones are perceived.
- The soundness of the device. Conference microphones are equipped with the ability to automatically adjust the sound pressure level. As a result, you can choose the best indicator for the meeting present.
When choosing microphones for conference rooms, taken into account an important aspect – each room has its own individual technical and acoustic characteristics.
There are many options for the selection conference microphones. However, do not neglect the technical characteristics, focusing only on the cost of equipment. One unsuccessful event can negatively affect the decision of your customers or partners, or ruin the reputation of an impeccable company.
