1.2 The MA “02” Series Amplifiers
The
Macro-Tech
®
series is a complete family of ampli-
fiers designed for pro sound reinforcement. Macro-
Tech amplifiers are designed to provide enormous lev-
els of pure, undistorted power in a rugged low-profile
package, utilizing Crown's patented
Grounded
Bridge
™ output topology. They also employ Crown's
patented
ODEP
®
protection circuitry, which keeps the
amplifier working under extreme conditions that would
shut down a lesser amplifier. Crown's new
Macro-Tech
“02” series amplifiers feature Crown's enhanced
PIP2
™
(Programmable Input Processor) expansion
system. The
PIP2
expansion system makes it easy to
tailor the amplifier to a specific application. Providing
high power amplification from 20 Hz to 20 kHz with
minimum distortion, Macro-Tech series amplifiers fea-
ture balanced inputs with bridged and parallel mono-
phonic capability. The MA-5002VZ includes additional
features not found on other Macro-Tech series models
including switchable compression, switchable loud-
speaker offset integration (LOI), and I
LOAD/ILIMIT indi-
cation.
