The 5-pin din was pretty common on old European gear.

1 Left audio in
2 Chassis ground
3 Left audio out
4 Right audio in
5 Right audio out

I believe the mystery 6-pin is for the mic, which had a built-in remote control.

Hope this helps!

I have some 1/4" tapes I'd like to transfer from an old Uher 4000 Report
recorder to CD.

Problem is that the "Radio/Phono" connection is a 5-pin din and I'm not sure
which pins (if any) will give me a line-out to feed to a soundcard line in.
There is also a 2-pin "Speaker/Earphone" out, and a mystery 6 pin din out
marked with a triangle (power?).

Any suggestions from Uher gurus?

Greg.
