Voice amplifiers: features, models, selection criteria

When organizing excursions, the necessary equipment is a voice amplifier. This is a simple technique that takes up little space, weighs a little, but at the same time allows the whole group to hear the guide well. Let's dwell on the features of these devices, popular models and selection criteria.

Loudspeaker and voice amplifier are, in fact, synonymous words that mean the same technical device with which you can amplify the sound of a voice many times over. This is an easy-to-use equipment, it is especially useful in large auditoriums or on the street, when it is necessary to neutralize possible misunderstandings 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 addressing a large group of people, as well as if he works in a noisy room... The device is truly indispensable for those who, by the nature of their work, need to often strain their voice - these are representatives of such specialties as a guide, a member of a support group, a coach and an educator.

During its existence, voice amplifiers have evolved considerably. While the earliest models resembled a trumpet-horn, today they look like compact belt-type radios. By the way, some models are in fact equipped with additional functionality, including a radio. The fact that the loudspeakers have become quite miniature does not mean at all that the sound quality suffers from this - excellent audibility remains in a wide range. Only another, louder noise or serious hearing problems in those people to whom the appeal is addressed can interfere with hearing such a sound.

It should be noted that modern amplifiers have pretty good clarity. Many will remember that in earlier years the sound emanating from electromechanical horns was hoarse and accompanied by background noise. Modern equipment, as evidenced by numerous reviews, has no complaints.

We will give an overview of popular models used in various fields of activity.

These portable amplifiers are lightweight and compact equipment, very easy to use and stylish in design. It is intended for the work of lecturers and guides, is used in the public warning system, and is also common among people with pathologies of the vocal apparatus.

In order to choose the right voice amplifier, it is necessary to determine in advance the requirements for the equipment, by answering the following questions:

• in what conditions the loudspeaker will work;
• what is the capacity of the equipment;
• the size.

So, for excursions in buses, a compact model with low power and economical energy consumption will be sufficient.

When choosing an excursion model for the street, you should take into account the peculiarity of the terrain. For example, on a crowded busy highway, powerful microphones are needed, and for lectures on the historic streets of the city, you can limit yourself to a device with a low power.

If a microphone is needed for organizing advertising, then you need equipment that can work without recharging for a long time, while giving loud and clear sound. It must have an audio transmission option in order to play a file recorded on a USB flash drive. Such speakers are very often used near stores to attract the attention of potential buyers.

Modern units are on sale in a variety of sizes - you need to make a decision in favor of one or the other based on how you will use the device. For example, for short-term classes, you can choose absolutely any technique, and if you plan to walk with a microphone all day, then it is better to take care of buying a tiny version - otherwise, after a few hours you will feel tired.

The quality of the output of the drives is of no less importance; they should not have potential creases. The device's long lifespan is largely determined by how vulnerable the outputs will be - how they are connected and what the braid is made of. In recent years, models in a textile braid-cord have been popular. They are slightly more expensive than traditional ones, but their service life is also longer.
