Thanks Joe - we got them working at last, here's a pic of the results!



Added a pair of P&G faders (on the outputs) from an old neve console too.

bump…..

I can get more pics if that would help, would really appreciate some input on this!

Bump.. any ideas?

Hi, I sent this question through to sales and didn't get a response, so maybe this is the more appropriate "forum" I have 4 neve 1271 with the BA183AM cards populated and a gain pot for use as a mic pre.
