Round, push-fit connectors available in 2-8, 13 & 14-pin versions, including 3 different 5-pin types, and 2 different 8-pin types. Line plugs, line sockets and panel mounting sockets are available. 3-8 pin types all have the same size shell, and some are interchangeable (e.g. a 3-pin plug will fit a 5-pin socket). A notch in the shell ensures the plug will only fit one way round. Most common is the 5-pin 'A' type, used for audio and computer keyboard connections.
2-pin - loudspeaker connections
5-pin - audio line level input/output (e.g. 'tape'), keyboard (not PS/2)
8-pin - stage lighting control (6 channel 0-10V analogue)
13 & 14-pin - Atari computer equipment
Other applications requiring a low voltage mutipole connector
Mini versions of these connectors are also available - see here for data.
Note the odd pin numbering - designed so that the pin numbers stay the same regardless of the number of pins in the connector:
|Pin||Pulsar Equipment||Strand Equipment Etc.|
|1||L.V. Supply (18-25V)||Channel 1|
|2||Ground (0V)||Channel 2|
|3||Channel 1||Channel 3|
|4||Channel 2||Channel 4|
|5||Channel 3||Channel 5|
|6||Channel 4||Channel 6|
|7||Channel 5||L.V. Supply (-ve Strand, +ve others)|
|8||Channel 6||Ground (0V)|
Low Votage Supply provided by dimmer packs etc. to
Check with the manufacturers if in doubt as to which type of wiring your equipment uses. Be careful when connecting equipment from different manufacturers.

Normally solder connections. Thread outer cover onto cable, solder wires to pins, then assembly 2 halves of shell around connections and close cable clamp with pliers. Slide the plastic cover over the shell - a tab on the metal shell holds it on (you will need to bend the tab in to remove the cover again). 2-pin plugs/sockets may have screw connections and a push-on cover.
Normally solder connections. It may help to fix the socket to the panel first to hold it steady.
