AV receivers 5.1
5.1
— in fact, the most modest option for modern AV receivers; devices that work with a smaller number of channels (2.0, 2.1, 3.1) are practically not found on the market.5 main channels (centre, left-right front and left-right rear) are considered the minimum necessary to provide full-fledged surround sound, perceived "from all sides". And only one channel for the subwoofer, on the one hand, provides a minimum reliability of low frequencies, on the other hand, it guarantees ease of installation and tuning of the bass speaker.
