Audio cables are necessary to connect audio sources like iPods with audio outputs like speakers. The jack can be found at the audio cable’s end and forms the connection between the audio port and cable of the receiver. Audio cable jacks can be TRS connections and RCA connectors.
Those who buy Keystone Jacks must understand the various purposes for RCA cable jacks and TRS cable jacks as well as digital cable and composite jacks. Understanding the various kinds of jacks will help people pick the best cable jack for his audio needs.
Audio Cable Jack Conductors
Cable jacks differ when it comes to audio properties and connection configurations. Two-conductor audio jacks offer an unbalanced mono connection. Meanwhile, three conductors provide balanced or unbalanced stereo.
- Male-female connectivity. Generally, the audio cable jack offers the male plug. The female socket is part of the main equipment. Also, panel sockets and line plugs are available in other configurations that include heavy-duty current capacity, right angle plugs and different cable sizes.
- Mono-stereo compatibility. Audio jacks used to be usually used with electrical guitars, headphones, loudspeakers and microphones. Later, the market introduced a three-conductor version which was used in stereo headphones. Today, almost all plugs fit all sockets. Cable audio jacks now can connect other electrical items like two-way radio as well as cordless and mobile phones, portable DVD players, camcorders and digital cameras.
Uses of Audio Cable Jack
Audio cable jacks contain sockets and plugs. They are used for various audio connectivity needs. Various jacks can conduct electrical information in order to produce various kinds of sound experiences.
- Balanced audio connection. A TRS connector facilitates this connection between a couple of monaural conductors. It usually comes with balanced microphone inputs and small audio mixing desks.
- Unbalanced audio. A connection usually called “ring send, tip return” is audio cable jacks in which the tip provides the left channel output and the right provides the right channel input. But, mixers that have unbalanced input points use the older “ring return, tip send” connection mode. In such cases, the two-conductor mono jack plug grounds the input. Usually, professional audio mixing desks use an audio cable jack that has a combined send-return function.
- Computer sound. TRS connectors are a necessary part of connecting sound cards of personal computers to audio outputs that include surround sound and microphones.
