What are the different types of home theater amplifiers?

Home cinema amplifiers increase the audio signal coming from TV, digital versatile (DVD) or other device player, so it is loud enough to be reproduced by one or more speakers. Since domestic theaters come in many configurations, there is a number of AMPs to support different audio settings. In general, domestic cinema amplifiers are classified according to their outputs defined in Watts, the number of sound channels that support, and any other features they provide. This information is often given in the product name or is projected on the packaging. The number of watts indicates the system volume, with higher values ​​showing higher levels of volume. For large media rooms, it is often necessary to use a higher power amplifier, because the sound must be loud enough to travel by some distance without Losinug too much power. However, the amplifier must correspond to the performance of the speaker performance with which therods to prevent damage.

In addition to the various performance rating, home cinema amplifiers are usually classified according to the number of sound channels that support.

For example, the number of channels can be listed as "5.1" or "7.1". Thčíclo is the number that AMP provides a reserved subwoofer output while the previous number determines the number of speakers except subwooferu that supports the amplifier. Multi -channel amplifiers are commonly used to produce a more uniform and realistic home signal in the home.
