Macro-T
ech
Building on our experience with the MT series, Gerald and
Jim developed the Macr
o-T
ech Series in 1987. It added Plug-
In-Pr
ocessors (PIP
™
car
ds) and of
fer
ed a better appearance.
Jim W
o
rdinger r
emembers, “In the early days we’d compar
e
MA amplifi
ers side-by-side with competitive amps. Ours had
mor
e punch and deeper bass, which I attributed to mor
e output
voltage and curr
ent.”
The huge Macr
o-T
ech 10,000 amplifi
er was basically an MRI amp
modifi
ed for audio use with a new audio inter
face and fr
ont panel.
It was developed for John Royer and
Tom Allebrandi who did sound for the
Indianapolis 500. Thr
ee of these amps
wer
e modifi
ed to drive the race track’
s
240V distributed-speaker system —
replacing two huge war
-surplus amplifi
ers
fr
om a battleship.
“W
e supplied the fi
rst Macr
o-T
ech
pr
ototypes to John McBride of MD
Systems, doing a tour for Gar
th Br
ooks.
At one gig, the FOH engineer noted that
he had to keep pushing the level up in
the midrange. The pr
oblem wasn’
t with
the amps. Actually
, MD had bur
ned up
two-thir
ds of the midrange drivers because
they wer
en’
t used to seeing that kind
of power
. Cr
own shipped in 24 drivers,
installed them, and wir
ed them dif
fer
ently
.
Pr
oblem solved. That’
s the kind of suppor
t
Cr
own would do.”
