What the heck is “S/PDIF?”
No, it’s not a typo. S/PDIF stands for “Sony/Phillips Digital Interconnect Format,” or “Sony/Phillips Digital Interface,” and is a means through which users may transmit audio signals digitally, which makes for higher fidelity: digital in, digital out. Right now, there are two consumer-level digital transmission interfaces: HDMI and S/PDIF. Most people reading this probably know that HDMI transmits both video and audio, however, what you might not know is that S/PDIF only transmits audio.
So you might ask, “Why bother with S/PDIF then?” Well, not all equipment has an HDMI input or output, which should be pretty obvious when dealing with things like audio interfaces and reference monitors that don’t handle video signals. In some situations, like separate sound and video outputs from computers, you might even need to hook up both HDMI and S/PDIF cables.
S/PDIF has two different types of connectors: coaxial (RCA) and optical (TOSLINK). The coaxial cables are usually found colored orange in order to differentiate between other colored RCA connectors such as yellow for video, and red and white for analog audio. The optical cables are far more delicate and are made of fiber optics.
The upcoming combos…
We at Sonic Electronix value high-fidelity audio above all else, and that’s why we’re currently putting together combos that link pieces of gear based on S/PDIF. The picture above is taken from the Infrasonic Blow 4D reference monitors, about which I also recently wrote a blog. We’ll be pairing up these fantastic speakers with just about any piece of gear in our inventory that has S/PDIF output, and as always, we’ll be offering them to you at the special discounted prices you love and have come to expect from Sonic Electronix!
