GLOSSARY
Audio cables / Plugs and sockets
5-pin DIN plug
The 5-pin diode plug is being simplified also described as a 5-pin DIN plug. DIN is the
abbreviation for Deutsche Industrie Norm (German Industrial Standard) and indicates
that it is a nationally standard plug.
More recent equipment is no longer fitted with this sort of plug. Nevertheless, there are
still many older equipments in use that have 5-pin DIN sockets.
Consequently there is a requirement for a wide variety of adapters to combine old and
new equipments. As the 5 pin plug / socket combines both audio input and audio output
(record left, record right, play-back left, play-back right), when selecting cables or
adapters attention must be paid to the correct connection. Detail to be taken from the
current product information.
Plug
Depending on the size of the equipment, plugs come in sizes with diameters of 2.5 mm,
3.5 mm and 6.3 mm. There are mono or stereo versions of all variants.
While the solid 6.3 mm plugs are mainly used with Hi-Fi headphones or microphones, the
smallerplugs are used increasingly with portable equipment, such as Discman, MP3 players
and iPods.
Similarly, their use with laptops, sound cards, etc., is increasing. Plugs and sockets with
differing diameters can be connected with various adapters. Relatively new is the small
4-pin plug that carries video as well as stereo audio signals.
RCA plug
RCA plugs are some of the most widely used plugs in the audio/video field. They generally
have coloured markings to ensure correct connection and they come in various types.
Speaker plug
Speaker plugs provide a secure and robust cable to equipment connection. In particular,
when there is frequent connection of components, they facilitate handling. In practice,
however there is more and more equipment (amplifiers as well as speaker boxes) where
the stripped cable is directly clipped in.
With older and standard equipments as well as car radios, these plugs are still useful.
