What is a stereo amplifier?
Sound amplifiers are specifically designed to improve the sound quality by minimizing the various distortions when the strong volume.
In life, usually the problem is as follows: included on all or nearly all of the volume of speakers emits strange wheezing noises, squeaks, etc. In fact, the problem lies on the surface: built-in amplifier radio simply can not handle the load assigned to it in the form of the subwoofer and/or high-end sound system. It is this phenomenon and aims to remove the amplifier.
Ideally, the amplifier must not make changes to the sound; it just needs to maintain its quality at the proper level.
Recommendations for the correct selection of the amplifier
1. We recommend paying attention to the manufacturer's equipment. It is better to trust in proven companies operating on the market for decades. For example, the well-proven Rockford Fosgate, DLS, Audison. Equally good popular "folk" manufacturers, for instance, Pioneer, JVC, Kenwood.
2. The amplifier sound quality is important when choosing an amp to speakers. Do not be shy to get acquainted in detail with the characteristics of the equipment, ask to listen to the sound sample.
3. Power is of particular importance when choosing an amplifier for the subwoofer. Navigate stands at rated power since the maximum rate is highly inflated and rarely corresponds to the real possibilities of the equipment. Well, if the product is factory passport, where all the characteristics (including the acquired during tests) are detailed.
4. It is necessary to determine the location for the installation of new equipment. Typically, the device is placed in the luggage compartment of the car: the cellar, the seat back, bezel, etc. From this factor will depend on the appearance and design features of the device.
5. For a large candy bar is very desirable to have a fan and remote volume control.
Single channel amplifier
They are used for subwoofers. They are called monoblock. The main difference of such equipment - an opportunity to work in the mode of low-resistance load (1-2 OM), so when a subwoofer is designed for high load (4-8 ohms), we can restrict the purchase of a two-channel amplifier.When connecting to a standard cassette recorder requires a remote volume control.
Two-channel amplifiers
This option is ideal for installation on two speakers and a subwoofer with a bridge connection. Sometimes, when you use that and other equipment used three-channel amps, but they are impractical and rarely decent quality. Typically, instead of them purchased other devices.
Four-amps
The most advanced and modern devices. There are ample options for the application: connect 4 speakers, 2 speakers and a subwoofer, 2 subwoofers. It is the most practical option equipment as in all cases provides optimal sound quality. Well assembled with two-channel devices.
Five-channel amplifier
They are used less frequently, although there may be a good alternative to the compact arrangement of the speaker. They have a high cost. Give the opportunity to connect 4 speakers and a subwoofer simultaneously.
