M A C R O - T E C H S E R I E S
T he Crown ® Macro-Tech ® Series is the defi ning
standard for amplifi er design today. No compro-
mises, no gimmicks. Just brilliant engineering
backed by superior manufacturing, support and an
unsurpassed commitment to quality. Like all Crown
amps, the defi ning characteristic of the Macro-Tech
Series is sonic accuracy. A tight, rock-solid low end,
with smooth, detailed highs and a well-defi ned mid-
range. In short, the most accurate reproduction of an
audio signal you’ve ever heard. And because we put
the quality of sound above all else, a Crown amplifi er
is the most coveted amplifi er in the business.
When it comes to manufacturing amps, our work is
based on one simple fact: there are no shortcuts to
quality. And our Macro-Techs have proven it time and
time again in some of the most demanding applica-
tions in the world.
The VZ ® Series is a signifi cant leap forward in ampli-
fi er design. Our patented variable impedance (VZ)
technology permits the MA-3600VZ or MA-5002VZ to
dynamically adapt to signal and load requirements in
real time. Whether you need current in a low-imped-
ance sub-woofer situation, or high-voltage swings for
those transient signals, the VZs deliver!

Specifi cations
Note: Specifi cations relate to 120 volt, 60 Hz units
in Stereo mode with 8-ohm loads and an input sen-
sitivity of 26 dB gain at 1 kHz rated power unless
otherwise specifi ed. Specifi cations for units supplied
outside the U.S.A. may vary slightly at different AC
voltages and frequencies.
Power
Output Power: See power charts below.
Load Impedance: Safe with all types of loads, even reac-
tive ones. MA-3600VZ is rated for 2 to16 ohms in Stereo.
MA-5002VZ is rated for 2 to 8 ohms in Stereo. Both
amplifi ers are rated for 4 to 16 ohms in Bridge-Mono and
1 to 4 ohms in Parallel-Mono mode.
Voltage Gain to 8 ohm load at rated output at 1 kHz,
maximum level setting:
MA-3600VZ:
124.6:1 ±6% or 41.9 dB ±0.5 dB at 0.775 volt
sensitivity.
69.2:1 ± 6% or 36.8 dB ±0.5 dB at 1.4 volt sensitiv-
ity.
20:1 ±6% or 26 dB ±0.5 dB at +26 dB sensitivity.
MA-5002VZ:

sensitivity.
71:1 ±12% or 37 dB ±1 dB gain at 1.4-volt sensitiv-
ity.
20:1 ±3% or 26 dB ±0.25 dB gain at the maximum
level setting.
Required AC Mains (MA-3600VZ): 50/60 Hz;
100, 120, and 230VAC (±10%) units are available.
230VAC, 50/60 Hz units can be used with 220 and
240VAC. All versions draw 90 watts or less at idle.
100VAC and 120VAC units can draw up to 30 amps;
230VAC units can draw up to 15 amps. Current,
voltage and frequency requirements are provided on
unit’s back panel.
Required AC Mains (MA-5002VZ): 50 or 60 Hz;
100, 120, 200, 208, 230, 240VAC (±10%). All units
draw 90 watts or less at idle. Current, voltage and
frequency requirements are provided on unit’s back
panel.
AC Line Connector:
MA-3600VZ: NEMA TT30P.
MA-5002VZ: 10 AWG cordset with NEMA TT30P
plug is provided on 120VAC, 60 Hz North American
units.
Performance
Frequency Response: ±0.1 dB from 20 Hz to 20 kHz
at 1 watt.
Phase Response: ±10 degrees from 10 Hz to 20 kHz
at 1 watt.
Signal-to-Noise Ratio: > 105 dB A-weighted or 100
dB unweighted below rated power, 20 Hz - 20 kHz.
Total Harmonic Distortion (THD):
MA-3600VZ: At full bandwidth power, < 0.05%
from 20 Hz to 1 kHz increasing linearly to < 0.1%
at 20 kHz.
MA-5002VZ: 1 kHz rated power, 0.05% or less true
THD.
Intermodulation Distortion (IMD): (60 Hz and 7 kHz
at 4:1)
MA-3600VZ: Less than 0.05% from 368 mil-
liwatts to full bandwidth power.
MA-5002VZ: Less than 0.05% from rated power to
35 dB below rated power at 8 ohms.
Damping Factor: > 1,000 from 10 Hz to 400 Hz.
Slew Rate: (Slew rates are limited to useful levels for
ultrasonic/RF protection.) > 30 volts per microsecond.
Controls
Compressor (MA-5002VZ only): A three-position
back-panel switch is used to control each channel’s
input compressor. The “fast” setting provides an
attack time of 4 milliseconds and a release time of
300 milliseconds; the “slow” setting provides an
Features
• Crown’s Grounded Bridge™ design delivers
large voltage swings without using easily
stressed output-transistor configurations
like conventional amplifi ers. The results are
lower distortion and superior reliability.
• Patented ODEP ® (Output Device Emulation
Protection) circuitry compensates for over-
heating and overload to keep the amplifi er
working when others would fail.
• IOC ® (Input/Output Comparator) circuitry
immediately alerts of any distortion exceed-
ing 0.05%, providing dynamic proof of
distortion-free performance.
• P I P ™ ( M A - 3 6 0 0 V Z o n l y ) a n d P I P 2 ™
(MA-5002VZ only) Programmable Input
Processor connector accepts accessory
modules that tailor the amplifier to suit
specifi c applications.
• Patented Variable Impedance (VZ ® )power
supplies for each channel provide excellent
crosstalk characteristics and the best power
matching to your load. In the MA-5002VZ,
three special modes are provided to control
how and when the supplies shift impedance
modes.
• Very low harmonic and intermodulation
distortion result in the best dynamic transfer
function in the industry.
• MA-5002VZ only: Independent error-driven
compressor for each channel that can be set
for fast or slow attack and release times.
• Full protection from shorted, open and mis-
matched loads; general overheating; DC;
high-frequency overloads; and internal fault
conditions.
• Three-Year, No-Fault, Fully Transferable
Warranty completely protects your investment
and guarantees its specifi cations.
