1 Welcome
The Crown
®
Macro-Tech
®
5002VZ is the
most advanced amplifier to offer Crown’s pat-
ented Variable Impedance (VZ
®
) power supply
technology. New semiconductor technology is
combined with superior VZ power supplies to
enable the Macro-Tech 5002VZ to pack unprec-
edented power levels into 5¼ inches (13.3 cm)
of vertical rack space. The Macro-Tech 5002VZ
also features enhanced PIP2™ compatibility for
access to custom input modules, and because
it’s a Macro-Tech, you have the added benefit of
ODEP
®
protection to keep the show going long
after other amplifiers would fail.
Modern power amplifiers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.
In addition, the MA-5002VZ amplifier includes
a number of features which require some expla-
nation before they can be used to their maxi-
mum advantage.
Please take the time to study this manual so
that you can obtain the best possible service
from your amplifier.
1.1 Features
• Grounded Bridge™ design delivers large
voltage swings without stressing output-
transistors, resulting in lower distortion
and superior reliability.
• Patented ODEP (Output Device Emulation
Protection) circuitry compensates for
overheating and overload to keep the
amplifier working when others would fail.
• IOC
®
(Input/Output Comparator) circuitry
immediately alerts of any distortion
exceeding 0.05%, providing dynamic
proof of distortion-free performance.
• Articulated VZ power supplies for each
channel provide excellent crosstalk char-
acteristics and the best power matching to
your load.
