Audio Cables: Solid Connections for Rich Sound

To enjoy your music to the fullest, a structured cabling setup for your devices is important. It may not be an exciting task for everyone, but only with the right cables can you achieve the optimal listening experience.

Which cables serve which function?

Coaxial, RCA, jack? Different audio cables have specific names that are crucial when choosing the right connection. To help you keep an overview in the cable jungle, we’ve put together a short guide:

  • RCA cables: You’ve likely connected your devices with an RCA cable—they’re among the most common cable types. They consist of two separate leads that carry analog signals. Thanks to the colored plugs, you can see at a glance which channel to use: the left plug is either white or black, while the right plug is red. RCA cables are typically used for analog connections. They’re easy to confuse with digital coaxial cables because both use the same RCA connector. The difference lies in impedance: coaxial cables use 75 ohms, whereas analog signals usually require 50 ohms.
  • Jack cables: Jack plugs are mainly used when connecting smartphones and high-quality MP3 players with a headphone output. Depending on the model, they fulfill different requirements based on the number of insulating rings on the plug. Cables that carry mono signals have two poles separated by one ring. In contrast, cables for stereo signals have two rings, creating three contact areas. This allows the cable to transmit the ground as well as two channels.
  • Coaxial cables: Unlike the previous examples, “coaxial” describes the construction of the cable. In these cables, the inner and outer conductors are separated. The (mostly) digital signals are transmitted only via the inner conductor. Whether a coaxial cable is suitable for digital signals can be determined by its impedance. Over longer distances, this construction has the edge. They are connected—just like RCA cables—using an RCA plug.
  • HDMI cables: When it comes to movies and home cinema, HDMI cables are indispensable. The abbreviation stands for High Definition Multimedia Interface. These cables transmit both video and audio. By combining both, you need fewer cables and reduce interference. It’s especially convenient if your TV supports HDMI ARC. The abbreviation ARC stands for Audio Return Channel and means the device can not only send but also receive audio via a suitable HDMI cable. This way, you don’t need a separate cable between your AV receiver and your TV. The enhanced version for even clearer sound is eARC; it’s included from HDMI version 2.1 onward, while ARC is available starting with HDMI 1.4.
  • TOSLINK cables: TOSLINK cables connect via the so-called S/PDIF interface. Unlike coaxial cables, they don’t carry electrical signals but light signals. This type of transmission is barely susceptible to interference. Because of this optical transmission, they’re also known as “optical cables” or simply “opto cables.”
  • Subwoofer cables: Subwoofer cables have one input but two outputs (Y-cable). They belong to the RCA family and feature reinforced inner conductors. Here you connect a single cable rather than a pair. It’s important to use an active subwoofer.

Protect your audio cables

Your audio cables perform a vital function—without them, your system or TV remains silent. To ensure long service life and interference-free sound, treat them carefully. You won’t need to move them often, but caution is still advisable. Cables should never be kinked, as this can damage the fine conductors.

Use our right-angle adapters for RCA cables to route them in a space-saving way without bending them. If a cable is too short, we offer extensions for your audio cables. To avoid tangled cords, many people use cable ties. A more elegant solution is our cable sleeves, which you simply zip over the cables like a scarf. There’s room for up to 10 cables, and they can be released just as easily. The fabric is heat-resistant, so you don’t need to worry during operation.
