How to Understand Audio Cables

• Chances are you have audio cables everywhere; they connect headphones and MP3 players, computers and speakers, and many video game consoles with audio/video receivers. Many types of audio cables exist, but only a few are commonly used in homes. Learn more about the cables you have in your home.
• Audio Signals
• Audio cables use two types of audio signals: analog and digital. Analog audio signals use a continual electrical signal that varies in frequency and amplitude to transmit sound. Digital audio signals use bursts of electrical impulses to transmit sound. Digital signals are superior because they are less susceptible to signal loss and distortion.
• Construction
• Audio cables have a conductor, shielding and insulation. The conductor transmits electrical signals, and it's either a solid wire or multiple smaller wires stranded together. Shielding prevents signal interference, and the types of shielding are braided, foil and spiral. Insulation protects the shielding and the conductor from damage and functions as a fire preventative.
• Analog Cables
• Common analog cables are RCA (or "composite") and 3.5-millimeter headphone cords. RCA cables usually come in pairs, with red and white connectors on each end for right and left stereo sound. Headphone cords plug into a single jack, usually colored green.
• Digital Cables
• Common digital cables are coaxial digital and optical cable (or "Toslink"). Coaxial digital cables are thicker than RCA cables but otherwise are nearly identical. Optical cables are single cords that plug into sockets shaped somewhat like squares and commonly labeled "digital optical."

How to Connect Optical Audio Cables

• The use of optical audio cables on your home entertainment system is a good way to experience high-quality digital audio. The audio quality surpasses that of coaxial or RCA audio connections, and the connection process could not be simpler, as it only involves connecting a single cable from one device to another. The most common optical audio connections used are from an audio output device like a DVD player, Blue-ray player, or cable set-top box (STB) to an audio input device like a television or a home theater amplifier. For the purposes of demonstration, this guide will assume you are connecting a cable STB to a home theater amplifier, but the same process can easily be applied to any device with optical audio connections.
• Things You'll Need
• Optical audio cable
• Two devices with optical audio connections
• Instructions
• Connect one end of the optical audio cable to the STB. Locate the optical audio output connection on the back panel of your cable STB. Often, manufacturers will place a plastic cover over the optical audio connection to prevent any damage to the optical audio components. Remove this cover by hand and connect one end of the optical audio cable to the optical connection on the STB.
• Connect the other end of the optical audio cable into the amplifier. Locate the optical audio connection on the home theater amplifier, making sure it is labeled "input" and not "output." Remove the plastic cover if there is one and place the other end of the optical audio cable into this optical connection.
• Test optical audio functionality. Power on the STB and set the home theater amplifier to the optical audio input setting and see if you get sound.
• Tips & Warnings
• Some cable STBs need to be set to output audio through digital rather than analog audio connections. This can usually be done through the internal settings menu of the STB. Contact your cable TV provider with any questions.

How to Install Optical Audio Cables

• Most audio cables use a wire to transmit electrical signals. But optical audio cables use fiber optic communications to transmit light. This makes them immune to the electrical interference that typical cables are subject to. Optical audio cables (also called TOSLINK or EIAJ optical cables) are a high-quality and affordable alternative to standard audio cables. Plus, they are easy to install. Because optical audio cables transmit digital data, they are most often used for connecting digital audio source devices (such as DVD players) to home theater systems. Generally, optical audio cables use the S/PDIF protocol (Sony/Philips Digital Interconnect Format), which is a communication format for digital signals.
• Things You'll Need
• Digital source device
• Digital receiving device
• Optical audio cable
• Instructions
• Check that each device accepts optical audio cables. The connection port is usually labeled "Optical," but it may say "Digital" instead. In either case, the connection port must be square with a rounded bottom if optical audio cables are to be used.
• Remove and save the plastic protective covers from each end of the optical audio cable.
• Connect one end of the optical audio cable to the port marked "Optical In" (or "Digital In") on the receiving device. The plug will click to let you know it is fastened securely.
• Connect the other end of the optical audio cable to the port marked "Optical Out" (or "Digital Out") on the source device. The plug will click to let you know it is fastened securely.
• Turn on both devices if they are not already on.
• Test the connection by operating both your devices normally to ensure the cables have been installed correctly.
