hi,
i found a digidesign 882 i/o audio interface on the sidewalk this weekend w/o a power supply.
the specs for psu:
Input: 100-240 Vac
EING 50/60 Hz
1.0A Max
Output: +5Vdc/3.0A
+15Vdc/2.0A
-15Vdc/0.5A
36W Max
UMEC
AC Adapter UP0403A-03P
can i just use an inverting op amp on a 5v 12v power supply & be done?
or is 3v too big a difference (15v may just be for balancing the analog signal)?
