Default input sensivity / headroom on amplifier

hi

i've a question about the input sensitivity of the amplifier electrovoice
P3000

data sheet EvP3000:

www.electrovoice.com/electrovoice/EVfiles.nsf/lookup/P3000/$File/p3000-eds.p
df
( ..../p3000-eds.pdf )


input sensitivity=0dbu (0,775 Vrms)
maximum input level=+20 dbu (7,75 Vrms)

i have two meter before the amplifier input:
-Rms Vu meter that display 0dbVU whit a 1 khz sine @ 0 dbu
(max display=+3dbVU)
-Peak led meter that display 0db whit a 1 khz sine @ 0 dbu
(max display=+24db)

i work in live (much peak and not much rms), so i wish to put a
maximizer/compressor @ L/R, after the maximizer a
RMS limiter (set@0 dbu), and after all a peak limiter (set@+19 dbu)....
..... al before the meter (Vu and Peak), so i can keep under control in every
time the signal that go to the EvP3000, a signal where the rms don't go up
0dbVu and peak don't go up +19db.

what did you think about this?
is a correct way to take the full 1200Wrms @4ohm from the Ev3000
without distorsion, or a stupid way to crash all the system?

thank's a lot, and excuse my very bad english.

marco
