What is a key advantage of using S/PDIF (Sony/Philips Digital Interface) connections for audio?

• A. They are less vulnerable to electrical interference.
• B. They require more power.
• C. They always carry video as well.
• D. They are incompatible with most receivers.

Answer: (A)

S/PDIF delivers audio as a digital stream, so the information is represented by bits rather than varying analog voltages. This makes the path much less susceptible to electrical noise, hum, and interference that can degrade analog cables. The receiver rebuilds the audio from those bits and can detect and correct errors, so the result is cleaner sound with less susceptibility to cable issues. This digital nature is why it’s preferred for reliable, high-quality audio transfer between a source and a receiver. Remember, S/PDIF carries audio only (no video) and can use coaxial or optical cables, and it supports both PCM audio and various encoded surround formats; it doesn’t require more power and is generally compatible with most receivers.
