Default Re: Ferguson 3V55 Videostar VCR

The audio output will be on pins 3 and 5, with 2 common. A 7-pin DIN socket might additionally carry video on pin 6 (in) and 7 (out).

Note the pins are NOT numbered in order 1-2-3-4-5-6-7 as you might na´vely expect, but 6-1-4-2-5-3-7; this is because the original standard was 3 pins for two-way mono audio with a common earth, then later pins 4 and 5 were added to give stereo audio but a 3-pin plug would still fit the 5-pin socket, and even later pins 6 and 7 were added for additional signals.
