Audio receivers with I2S interface

I2S

— the presence in the receiver of an input and/or output for a digital audio signal in the I2S format. This format is mainly intended for signal transmission within audio devices, but sometimes it is also used for communication between devices; the latter is implied in this case. The I2S interface does not have a standard connector; it can use ports of various types — in particular, BNC, RJ-45 (LAN) and even HDMI. Anyway, the purpose of this connector is similar to the coaxial S / P-DIF (see "Inputs", "Outputs"); while the I2S standard, on the one hand, provides higher quality and noise immunity, on the other hand, it is less common and significantly affects the cost of devices.
