Jerry says my AERCO MP-2 clips at +27dBM:
The AERCO clips at about +24 dBM which in the special case of a standard (600
Ohm) load is the same as dBv. Since the preamp can drive a 600 ohm load with
~0 loss of signal (low output impedance), the dBU (unloaded output)
is the same.
So as long as I don't go over +6dBV into the Korg, I won't have brickwalling problems, right?
Yes, for MR-1 balanced input, unbalanced is ~+3 dBv max.
Seems using a 15 dB pad at the preamp balanced output should protect against MR-1 overload clipping, or if not caring to run the preamp in that high voltage output 'cruise' mode, just use ~15 dB lower preamp gain so output is OK with MR-1.
Using LINE input on
some decks, and running really hot signal, but turning down REC level adjust avoids slamming the deck, but since no one has sent me MR-1 for bench testing as yet, can't tell you if MR-1 can handle anything over +9 dBv input specification.
