AV receivers with Bluetooth playback

Bluetooth

— a technology for wireless transmission of data over short distances — usually about 10 m in the absence of obstacles. Although in general this standard is very versatile, however, in receivers its use is most often limited to broadcasting music from portable devices to a speaker system. Such a connection is very convenient due to the lack of wires and the prevalence of Bluetooth in modern gadgets (for example, mobile phones without this technology are extremely rare). Its disadvantage is the limitations on the data transfer rate and the resulting relatively low sound quality; however, some receivers can partially compensate for the loss in quality through special tools.
