Crown MA-3600-VZ Brochure
MA-3600VZ
MA-5002VZ
he Crown® Macro-Tech® Series is the defi ning
standard for amplifi er design today. No compromises, no gimmicks. Just brilliant engineering
T
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 midrange. 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 applications in the world.
®
The VZ
Series is a signifi cant leap forward in amplifi 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-impedance sub-woofer situation, or high-voltage swings for
those transient signals, the VZs deliver!

Series, contact the Crown Technical Support Group

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
MA-3600VZ
MA-5002VZ
attack time of 12 milliseconds and a release time of
600 milliseconds; the “off” setting defeats outputdriven compression.
Enable: A front-panel push button used to turn the
amplifi er on and off.
Input Ground Lift (MA-5002VZ only): A two-position
back-panel switch located on the PIP2-FXQ used to
isolate the input audio signal grounds from the AC
(chassis) ground.
Level: A front-panel rotary potentiometer for each
channel with 31 detents is used to control the output
level.
Loudspeaker Offset Integration (MA-5002VZ only): A
two-position back-panel switch for each channel used
to turn the loudspeaker protection circuitry on and off.
The circuitry protects against DC, off-center woofer
cone movement, and unwanted subsonic and ultrasonic frequencies.
Stereo/Mono: A three-position back-panel switch
used to select Stereo, Bridge-Mono or Parallel-Mono
mode.
Sensitivity: A three-position switch used to select the
input sensitivity for both channels: 0.775 volts or 1.4
volts for standard 1 kHz power, or a 26 dB voltage
gain. MA-3600VZ switch is inside the PIP compartment; MA-5002VZ switch is on the back panel.
VZ Mode (MA-5002VZ only): A four-position switch
for each channel inside the front-panel used to control
the switching mode of the VZ power supplies.
Reset (MA-5002VZ only): A back-panel push button
for each channel used to reset the circuit breaker that
protects each power supply. 100 and 120 VAC units
have 15 amp circuit breakers; 230 VAC units have 7.5
amp circuit breakers.
Indicators
Enable: An amber front-panel indicator that shows the
on/off status of the low-voltage power supply.
Signal/IOC: A green front-panel indicator for each
channel that fl ashes to show amplifi er output. If a
channel’s output waveform differs from its input by
0.05% or more, the indicator fl ashes brightly to show
distortion. This function provides proof of distortionfree performance. In Parallel-Mono mode, the Channel
2 light stays on.
ODEP: Each channel has an amber front panel indicator that shows thermal-dynamic energy reserve. Normally, each ODEP indicator is lit to show available
reserve energy. The indicator will dim proportionally
as the energy reserve for its channel descreases. In
the rare event that a channel has no reserve, its indicator will turn off and the ODEP circuitry will limit the
channel’s output drive.
Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown amplifi er—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown amplifi er is warranted
to meet or exceed original specifi cations for the fi rst three years of ownership. During this time, if your amplifi er
fails, or does not perform to original specifi cations, it will be repaired or replaced at our expense. About the
only things not covered by this warranty are those losses normally covered by insurance and those caused by
intentional abuse. And the coverage is transferable, should you sell your amplifi er.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside of the USA,
please contact your authorized Crown distributor for warranty information or call 574-294-8200.
ILoad/ILimit (MA-5002VZ only): A two-color (green/
red) LED for each channel that shows load current
and limit current. They glow green to indicate load
current fl owing out the amplifi er, and they turn red
when maximum current is being delivered to the load.
Input/Output
Input Connector: Two balanced 1/4 inch TRS
(6.35-mm) phone jacks on the back panel and two
balanced three-pin female XLR connectors on the factory-installed PIP-FX (MA-3600VZ) or PIP-FXQ (MA5002VZ) module.
Input Impedance (Nominal):
MA-3600VZ: 20 k ohms, balanced. 10 k ohms,
unbalanced.
MA-5002VZ: Greater than 10 k ohms, balanced.
Greater than 5 k ohms, unbalanced.
Maximum Input Level: 13 volts peak.
Input Sensitivity: 0.775 volt for standard 1 kHz power,
1.4 volts for standard 1 kHz power, or a 26 dB voltage
gain.
Output Connectors (MA-3600VZ): Two sets of colorcoded binding posts.
Output Connectors (MA-5002VZ): A multifunction, high-current output block is provided. Crown
output blocks include three pairs of connectors for
each channel (a total of 12 connectors). This allows
multiple loudspeakers to be easily connected to each
channel. High current screw terminals and color
coded binding posts.
Output Impedance: Less than 10 milliohms in series
with less than 2 microhenries (MA-3600VZ) or 2.5
microhenries (MA-5002VZ).
DC Output Offset: (Shorted input) ±10 millivolts.
Output Signal
Stereo: Unbalanced, two-channel.
Bridge-Mono: Balanced, single-channel. Channel 1
controls are active; Channel 2 should not be used.
Parallel-Mono: Unbalanced, single-channel. Channel
1 controls are active; Channel 2 controls are
bypassed.
Protection
Macro-Tech amplifi ers are protected against shorted,
open or mismatched loads; overloaded power supplies; excessive temperature; chain destruction phenomena; input overload damage; and high-frequency
blowups. They also protect loudspeakers from input/
output DC and turn-on/turn-off transients.
If unreasonable operating conditions occur, the patented ODEP circuitry will proportionally limit the drive
level to protect the output transistor stages, particularly in the case of elevated temperature. Transformer
overheating will result in a temporary shutdown of the
affected channel; when it has cooled to a safe temperature, the transformer will automatically reset itself.
Controlled slew-rate voltage amplifi ers prevent RF
burnouts, and input overload protection is provided
by current-limiting resistance at the input.
Turn On: Four-second delay with no dangerous
transients. Delay time can be changed in the
MA-3600VZ (contact Crown’s Technical Support
Group). MA-5002VZ also has “soft start” to avoide
tripping the AC circuit breaker by gradually bringing
the supplies up to full voltage.
