Just got two of these... I'd like to stuff them in a 2-space rack and add a power supply (phantom power too)... Unfortunately I haven't found any documentation on the pin assignments -- any help would be great! 1rst time rackin a module, so I'm sure I'll have some other questions down the line...

..Or right now actually. I cracked it open just to see what was under hood, and saw two Lundahl tranny's -- one of which said 200hz-10,000hz on it... ??? AFAIK, this is a full range mic pre/eq module? Why the band-limited tranny?

are you sure it said Hz and not ohms?

A card:

7, 9, 13, 30 -> strapped together

23 -> pre eq o/p

16 -> +16v

17 -> CR

15 -> -16v

20 -> +8v

18 -> 0v

32 -> chassis

31 - o/p

24 -> direct i/p

22 -> pre eq i/p

10 -> i/p

11, 12 -> range +/-3db, set link


B card

30*, 31 -> mic low level i/p

28*, 29 -> mic hi level i/p

22*, 23 -> line i/p

1 -> line select

2 -> mic hi.lo select

3 -> mic hi/lo logic control

16 -> +16v

17 -> CR

15 -> -16v

19 -> +5v

18 -> 0v

32 -> chassis

9 -> o/p to A card

10 -> CR

11-12 link = -6db o/p

12-13 link = -10db o/p

no link = 0 db o/p
 
Gang of elk -- Thanks, much appreciated!!!

Dave -- Lol... I didn't even think of that, it probably did say ohms! I'll check when I get home just to be sure.

So looks like I need:

-16v
+16v
0v
+8v
+5v
48v for phantom...

I'm was thinkin I could get away with a dual primary 16v toroid. I'll do some reading up tonight, I not very good at this stuff... I'd think getting the voltages down to +8v and +5v won't be a problem, but what of the 48v? Might there be a better way to go about it? Also, what kinda amperage would I be looking at to feed two of these modules with the same power supply? I'll definately try to research and figure out as much as I can, but any hints would be cool too :)

Thanks guys,
Tim
