Hi Kevin, PCM provide two channel audio outputs. Multi-channel audio means two and more than two channels audio outputs. e.g 5.1 : 6 channels, 7.1: 8 channels, 13.1: 14 channels audio output.
Using HDMI port, you can send compress audio at other end, the receiver will decode and play the audio. e.g home theatre.
