That must be a Behringer marked chip in there :eek: :eek:

Actually there are two Beh-tles.

BE501, I guess, is for RMS detection
(either renamed DBX/THAT type chip, or -- less likely -- a CA transistor array. Would that make sense?)

BE267(?), not sure. But remembering Uli's philosophy of making gear as cheap as possible and thus making it available for all us peoples --> What generic 14-pin chip would perform the desired function? Vaguely informed and wild guesses...
- LM339 (a comparator) -- Uli B. likes sticking comparators where you wouldn't expect them (misused as opamps)  :eek:
- 13600 or the like (transconductance amplifier) -- makes sense there?

Just ideas, no guarantee.


ADDED:

BE267 = LM1894 (Dynamic Noise Reduction System DNR)
