What’s a SPDIF connection?
SPDIF, also written as S/PDIF, stands for Sony/Philips Digital Interface and is an interface to transmit digital audio. Digital audio means that the audio signal is transmitted encoded in series of "0" and "1" instead of being transmitted in analog format. This makes audio have higher fidelity, because no noise will be added to the audio signal. Therefore, it is always better to transmit audio in digital format. Currently, there are two consumer-level interfaces to transmit audio in digital format: SPDIF and HDMI (High-Definition Multimedia Interface). SPDIF transmits only audio, but HDMI also carries digital video signal. Guess what? WeTek Play has both, because It’s all inside.
