The assortment of musical technology is constantly growing. Almost every home has either branded computer speakers, or modern soundbars, or audio systems of various configurations. We will talk about the latter in this article. Let's figure out what these devices are and how to select them correctly.

What it is?

Before proceeding to a detailed examination of all the features of modern audio systems, you need to answer the main question: what is it? An audio system is a special electronic device or a combination of several devices that are designed to convert an analog or digital signal into sound (acoustic) waves.

Any other suitable electronic device can play the role of a direct source of the original signal in this case.

Device

Direct device of audio systems includes a set of several necessary components, each of which performs its own specific function.

• Converter . A radio tape recorder, CD player, MP3 player and other similar devices can act as a converter, and often a signal amplifier. The part under consideration is designed to receive signals from external sources, as well as their further transmission to the amplifier.
• Signal amplifier in audio systems it is often combined with a converter, but this element may well be made as a separate electronic device. The amplifier has an output or several outputs if multichannel acoustics are connected to it. The main task of the amplifier is to receive a signal that is relatively weak in amplitude, and then amplify it to the desired level and transmit it directly to the acoustics.
• Fuse - an important component of any audio system. This component will protect musical equipment from unforeseen dangers and in which case it will simply open the circuit. Usually the fuse is located on the power cable.
• Receiver . It is the main component of any home theater system. It is from it that the video signal goes to the visualization tool - a TV or a projector. In some devices, the role of the component in question is played by a DVD receiver, that is, a player that has all the necessary connections and communications in its body. The amplifier in the latter case can be placed in the subwoofer case.
• Food . Batteries depend directly on the type of audio system. For example, if the technique is inverter, then an inverter must be present in its device. If we are talking about acoustics that can work in an autonomous mode, then its design will necessarily contain a battery of a certain power.
• Acoustics , included in the device of audio systems, is represented by a set of passive and active sound emitters. Their main task is to convert the electrical signal into sound waves. Active-type speakers, in addition to the sound-emitting heads, are equipped with their own signal amplifiers.

Features of the internal circuit of audio systems largely depend on their configuration and the type itself.

Appointment

Audio systems produced by modern manufacturers perform a number of important functions. They process and reproduce sound. Wherein systems can be installed in different conditions . For example, it can be a car or computer audio system, which will play the role of a device that reproduces not only music tracks, but also system signals (notifications, errors or warnings).

Views

Audio systems are very different. In stores selling musical or household appliances, the consumer can find devices designed for different conditions and use. Consider what types of equipment such equipment is subdivided into.

Street

When making audio systems intended for outdoor use, manufacturers pay special attention to the protective mechanisms of the devices. At the same time, they are guided by the IP indicators - this is the security index. For instance, devices that differ IP54 can be used outdoors, as they are well protected from moisture, dirt, dust and even mechanical stress.

The equipment and power level of outdoor audio systems is usually higher. The technique is manufactured with the expectation of a wide coverage of sound waves.

True, it is quite possible to find on sale low-power outdoor audio systems, the power potential of which is limited within 10-400 W.

Multimedia

The most popular today are home multimedia audio systems, presented in a wide range. These models are available with different power ratings and different frequency ranges. Many devices have rich functional equipment . For example, Bluetooth, USB, NFC and many others may be provided. Multimedia systems can be floor-standing or shelf-based - a variety of options are sold in stores. Monoblock options are distinguished by high power indicators.

Multimedia acoustic devices can be connected to various devices - it can be a personal computer, laptop, smartphone, tablet computer. In such models, you can often find a rather expensive built-in DAC (digital-to-analog converter). Popular today and options, which provide connectors for a microphone (or 2 microphones) and the "karaoke" mode. The sizes of the considered acoustics are different. Multimedia systems are not always made very large and massive. Many firms produce compact versions, which in no way affects the level of their functionality.

Portable

Today, portable audio systems are also quite in demand. They are usually small in size and equipped with handy attachments to make them easier to carry . Most often this is a handle, but there are also manufacturers who supplement their musical technique with small wheels that facilitate quick and problem-free movement of equipment from one place to another.

Mobile audio systems are especially relevant for people who are in constant motion and cannot afford to put the acoustics in one permanent place without further transportation.

Wireless

Modern wireless technology proves to be convenient in operation. Such copies are produced by many well-known brands, for example, Sony, JBL, Samsung and many others.

Wireless audio systems come with a specific battery capacity. The last parameter has a direct impact on the duration of the equipment in autonomous mode. These devices are also manufactured to be multifunctional and practical. Many of them have high power ratings.

Manufacturers

These days, the market is literally overflowing with good well-known brands that produce audio systems of all types and modifications. Below is a small overview of the best manufacturers offering high-quality and functional acoustic devices for consumers to choose from.

Sony . The well-known Japanese brand is famous not only for the impeccable quality of technology, but also for the huge range of manufactured devices of all types. Sony audio systems are made practical, functional and durable - such equipment is rarely repaired.

True, many models of the brand's audio systems are slightly more expensive than many competitive options.

Noema . Russian manufacturer of acoustic systems. It is one of the oldest enterprises in Novosibirsk. Today, the domestic company specializes in the production of dynamic heads, acoustic systems, warning speakers, power amplifiers and accessories.

Bose . A well-known American brand that produces equipment of excellent quality. Bose audio systems are not the most expensive, but you can't call them cheap either. Especially powerful and versatile models can cost the buyer a tidy sum, but Bose technology is well worth the money.

Edifier . A popular manufacturer that produces a wide range of speaker systems. The equipment of this brand is famous not only for its excellent quality, but also for its affordable price. You can find a decent option for a very small amount.

How to choose?

Consider on the basis of what parameters it is worth choosing an audio system

• Decide on the purpose of the purchase . For example, office acoustics should not be too powerful, loud and complemented by various options, such as karaoke or color music. But the equipment for parties should just be multifunctional, characterized by high power indicators (expensive professional models are also suitable). If musical equipment is selected for home use, then everything here depends on the wishes of the owners and households - someone loves simple medium-power systems more, while someone likes options with loud sound and with many additional options.
• It is also important to consider the conditions in which you will use the acoustics . For outdoor use, it makes sense to buy only well-protected devices with high IP ratings. For home use, these parameters are not so important. If you need a system that you can carry with you, then wireless and portable copies are more suitable - you can choose the right solution for any request.
• Check out the technical specifications for your audio system . It is better to study them by looking at the accompanying documentation, since the parameters that sellers often talk about are in many cases exaggerated in order to lure the buyer. Choose the option with the best characteristics that will be appropriate for your living conditions.
• Inspect your appliances before purchasing . It is advisable to check the soundness of the audio system and listen to what sound it reproduces.
• Buy only high quality branded audio systems .

Not all branded equipment is prohibitively expensive - many manufacturers produce reliable and durable, but not at all expensive acoustics.

How to use?

The rules for using the audio system depend only on the features of a particular model. That is why it is so important to study the instructions for use of the equipment. Only here you can find out exactly how you can configure the equipment you bought, how to connect the necessary cables and install certain programs. However, there are general rules for most of these devices.

• Before connecting the audio system to the mains, make sure that the characteristics of the mains and the device match.
• Do not use equipment in rooms with high humidity and do not place water nearby.
• If your audio system has a Bluetooth adapter, Wi-Fi in combination with an Ethernet connector, then you will receive a digital audio stream from portable devices wirelessly. In this case, connecting extra wires will not be necessary.
• The most convenient way to set up and use the audio system is using the supplied remote control. If this device is not used for a long time, it is recommended to remove the batteries from it. Both old and new batteries cannot be used in combination.
• Do not place the audio system in direct sunlight and keep it away from heat sources.
• In the event of a malfunction, you should not disassemble the equipment yourself - go to the service.
