This equipment is easy to use, it is especially relevant in large audiences or on the street, when it is necessary to level out possible misunderstanding of words. Although the scope of such devices is much wider.
A voice amplifier will be necessary for every person who is faced with the task of contacting a large group of people, as well as if he works in a noisy room . The device is truly indispensable for those who often need to exert their voices by occupation - these are representatives of such specialties as a guide, a member of a support group, trainer and teacher.

During their existence, voice amplifiers have pretty much evolved. If the very first models resembled a horn pipe, today they look like compact belt radios. By the way, some models are actually equipped with additional functionality, including radio. The fact that the loudspeakers have become quite miniature does not mean at all that the sound quality suffers from this - the excellent audibility remains in a wide range. Only a different, louder noise or serious hearing problems in those people to whom the address is addressed can interfere with hearing such a sound.
It should be noted that modern amplifiers have pretty good clarity. Many remember that in previous years the sound coming from electromechanical horns was hoarse and was accompanied by a noise background. Modern equipment, as evidenced by numerous reviews, has no complaints.

How to choose?
In order to choose the right voice amplifier, you must first determine the requirements for the equipment by answering the following questions:
- under what conditions will the loudspeaker work;
- what is the capacity of the equipment;
- the size.
So, for carrying out excursions in buses there will be a sufficiently compact model with low power and economical energy consumption.
When choosing an excursion model for the street, one should take into account the peculiarity of the area. For example, on a busy busy highway, powerful microphones are needed, and for lectures on the historical streets of the city, you can restrict yourself to a low-power device.
If you need a microphone for advertising, you will need equipment that can work without recharging for a long time, while giving a loud and clear sound. It must have an audio transmission option in order to play the file recorded on the USB flash drive. Such speakers are very often used near stores to attract the attention of potential buyers.

For example, for short-term classes you can choose absolutely any technique, and if you plan to go with a microphone all day, it is better to take care of buying a tiny option - otherwise, after a few hours you will feel tired.
The output quality of the drives is no less important; there should be no potential creases on them. The long life of the device is largely determined by how vulnerable the outputs will be - how they connect and what the braid is made of. In recent years, models in textile braid cord have been popular. They are a little more expensive than traditional ones, but their service life is also higher.
