Default Re: Confusion over DIN sockets

Pin 1 on the leftmost socket is a low level input (@'2mV').

Pin 1 on the middle socket is a high level input (@'80mV'), potted down via a 1M and a 22k to be comparable with the low level input.

The inputs are selected via switch '2' which is shown in the low level position, with the potted down high level input shorted to ground.

The switches look rather like 'links' in the circuit diagram, which may be a source of confusion ?

Cheers
