Re: How to wire up the 24 channel router, DSUB pinout details needed

2012-06-17 by ataritt

Hi Peter and the rest..

I'm running the Series 3 MFX2 in polyphonic mode now, and it's a breeze to use it as a sound source, connecting it and putting polyphonic parts to selected mixer channels.

I noticed a level drop on some cards, but reseating the back side audioboards fixed that problem.
The machine has had a hell of a drive in the back of a truck when it was delivered to me from germany, and i'm very happy the machine works and sounds like it should.

Question:

Is the Fairlight fragile?

I suppose not, but fill us in please.

I think only the power supply and the hard and floppydrives (mine's busted anyway)are really fragile, as the boards seem to me (i do know a bit on electronics) very well engineered and designed.

Regards, Karel
