An audio-video receiver (or AV receiver) is a thing that plays almost the most important role in a home theater. The fact is that it is both a processor that converts a digital signal into an analog form, and an amplifier that makes speakers play, and a video signal switcher, and a radio receiver. A receiver is a whole system of various components. So her choice should be especially careful.
Instructions
Step 1
It should be noted that the most important part of the receiver, which is responsible for the correct decoding of digital information and for sound decomposition across several channels, is the multichannel audio decoder. Therefore, when choosing an AV receiver, pay attention to the presence of a standard format decoder. If the receiver is not able to handle the main digital formats, then you will not be able to watch some movies or listen to music. An example is the DTS decoder function: if it is absent, then you will be able to watch a movie of this format only if there is a decoder already built into the disc player, or if there is an external DTS decoder.
Step 2
Please note that the perception of sounds from the speakers will depend to a large extent on the power output of the amplifier. This power should be distributed evenly across all channels. So do not lose sight of the power of the front and rear speakers in your theater (it should be the same everywhere).
Step 3
It is also worth thinking about what exactly you are purchasing a receiver for. The fact is that for working with musical recordings, coloring the sound with a receiver will be completely unnecessary. But in the cinema, on the contrary, the additional brightness of the sound will come in handy. That is why in some models of receivers, switches from musical to cinema mode of operation have already appeared. And if you want to purchase a model, as they say, two in one, then it makes sense to pay attention to just such a development.
Step 4
Don't forget about the AV receiver's compatibility with wide-range DVD-Audio and Super Audio CD formats. These formats assume the receiver to operate with a dynamic range of 120 dB and in a frequency range that starts at 2 Hz and ends at 100,000 Hz.
Step 5
A digital-to-analog converter is of great importance when choosing a receiver. It is characterized by the sampling rate (its value will be indicated in the main characteristics of the device). By the way, the higher its value is, the better.
