Digital Audio Cables – Reliable Digital Signal Transmission

Digital audio cables are designed to carry digital audio signals between a wide range of Hi-Fi and home theatre components. They are commonly used to connect televisions, CD players, network streamers, DACs, media players, and AV receivers.

Unlike analogue interconnect cables, digital audio cables transmit the audio signal in digital form until it reaches the receiving device. The two most common formats are optical (Toslink) and digital coaxial (S/PDIF), with the choice depending mainly on the available connections on your equipment.

What Are Digital Audio Cables Used For?

Digital audio cables provide a reliable connection between source devices and amplifiers or DACs while preserving the digital audio signal.

Typical applications include connecting:

• TVs to AV receivers;
• CD players to DACs;
• network streamers;
• media players;
• devices equipped with optical or coaxial digital outputs.

Optical or Digital Coaxial?

Optical (Toslink) cables transmit digital audio using light, making them immune to electrical interference. Digital coaxial cables use a 75-ohm copper cable with RCA connectors to carry the same digital audio signal. The correct choice depends on the connections available on your equipment.

How to Choose a Digital Audio Cable

When choosing a digital audio cable, consider the connector type, required cable length, and compatibility with your equipment.

Before making your decision, consider:

• optical or coaxial connection;
• required cable length;
• connected audio components;
• connector quality;
• future system upgrades.
