Yeah, Andy's Farnell part number seems fine. Andy (Sintech) may be coming here on Wednesday so we can discuss this subject then.
This is a 6 way Bicc type part as commonly used to connect the SSL patchbay wiring to the upper buscard. 3 holes (hot, cold and screen) are for the odd channels (1,3,5 etc) and 3 are for the the even channels (2,4,6 etc). Each 6 way Bicc type connector would supply two channels of inputs or outputs for mic (B), line (D), insert sends (E), insert returns (F), group monitor inputs (G), Tape mon inputs (K) and track remotes (H or Y? - hardly used these days as a result of ProTools etc).
My memory fades me here somewhat but it is mostly right. Will talk with Andy S when he visits here very soon.
Sorry I haven't been active on here for a while but I'm very tied up with moving home at the moment! Should be more sorted sometime in February or March hopefully.
