philosophy of pr

possible under both nor

operation conditions. T
o
achieve this, our
engineers examined all the factors in amplifi

design and operation. The r

patented Cr

Macr

reliability that Cr

, combined with
Cr

No other amplifi

versatility in delivering ear
th-shaking power as
Macr
o-T
ech. Thr

cir
cuitr
y,
each Macr
o-T
ech can drive high output
levels into massive loads while achieving the
lowest distor
tion and gr
eatest r
eliability
.
The Gr
ounded Bridge utilizes output transistors
in a ver
y
effi
cient four
-quadrant bridge which
is immune to dynamic cr
ossover distor
tion.
With this bridge design, the transistors shar
e
the same voltage, curr
ent and load so only one
power supply is r
equir
ed per channel. This
results in an effi
cient use of both power supply
cir
cuitr
y and chassis space. Rapid, unifor
m
heat dissipation is pr
omoted by our transistor
mounting and heat dif
fuser designs. Smaller
,
mor
e compact chassis can be used which
pr
ovide a ver
y high output power to size and
weight ratio.
