the manufacturer, or sold with the apparatus. When a cart is
used, use caution when moving the cart/apparatus combination
to avoid injury from tip-over.
13) Unplug this apparatus during lightning storms or when unused
for long periods of time.
14) Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has been
spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate normally, or has been dropped.
15) Use the mains plug to disconnect the apparatus from the mains.
16) WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR
MOISTURE.

MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as
preamplifiers or tape decks directly above or below the unit.
Because this amplifier has a high power density, it has a strong
magnetic field which can induce hum into unshielded devices that
are located nearby. The field is strongest just above and below the
unit.
If an equipment rack is used, we recommend locating the amplifier(s) in the bottom of the rack and the preamplifier or other sensitive equipment at the top.
FCC COMPLIANCE NOTICE
This device complies with part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
CAUTION: Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

1 Welcome
The Crown
sional power amplifier features Crown’s patented Variable Impedance (VZ
supply. This power supply, along with
advanced semiconductor technology, enables
the Macro-Tech 3600VZ to pack more power
into a mere 3½ inches of vertical rack space
than ever before. Because it’s a Macro-Tech,
you have the added benefit of PIP ™ compatibility for access to custom input modules and
ODEP
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-3600VZ amplifier includes
a number of features which require some explanation before they can be used to their maximum advantage.
Please take the time to study this manual so
that you can obtain the best possible service
from your amplifier.

and superior reliability.
• Patented ODEP (Output Device Emulation
Protection) circuitry compensates for
overheating and overload to keep the
amplifier working when others would fail.

Macro-Tech MA-3600VZ Power Amplifier
3.1 Unpack Your Amplifier
Please unpack and inspect your amplifier for
any damage that may have occurred during
transit. If damage is found, notify the transportation company immediately. Only you can
initiate a claim for shipping damage. Crown
will be happy to help as needed. Save the shipping carton as evidence of damage for the shipper’s inspection.
We also recommend that you save all packing
materials so you will have them if you ever
need to transport the unit. Never ship the unit
without the factory pack.YOU WILL NEED (not
supplied):
• Input wiring cables
• Output wiring cables
Rack for mounting amplifier (or a stable surface
for stacking)
WARNING: Before you start to set up
your amplifier, make sure you read and
observe the Important Safety Instructions found at the beginning of this
manual.
3.2 Install Your Amplifier
CAUTION: Before you begin, make sure
your amplifier is disconnected from the
power source, with power switch in the
“off” position and all level controls
turned completely down (counterclockwise).
Use a standard 19-inch (48.3 cm) equipment
rack. See Figure 3.1 for amplifier dimensions.
You may also stack amps without using a cabinet.
NOTE: When transporting, amplifiers should be
supported at both front and back.
3.3 Ensure Proper Cooling
When using an equipment rack, mount units
directly on top of each other. Close any open
spaces in rack with blank panels. DO NOT
block front or rear air vents. The side walls of
the rack should be a minimum of two inches
(5.1 cm) away from the amplifier sides, and the
back of the rack should be a minimum of four
inches (10.2 cm) from the amplifier back panel.
Figure 3.2 illustrates standard amplifier airflow.

3 Setup
Macro-Tech MA-3600VZ Power Amplifier
3.5 Choose Output Wire and Connectors
Crown recommends using pre-built or professionally wired, high-quality, two-conductor,
heavy gauge speaker wire and connectors. You
may use banana connectors, terminal forks or
bare wire for your output connectors (see Figure
3.5). To prevent the possibility of short-circuits,
wrap or otherwise insulate exposed loudspeaker
cable connectors.
Note: Binding post outputs on European
models come with safety plugs installed
to prevent European power-cord plugs
from being inserted. The side entry positions for these connectors should therefore be used.
Using the guidelines below, select the appropriate size of wire based on the distance from
amplifier to speaker.
Distance Wire Size
up to 25 ft. 16 gauge
26-40 ft. 14 gauge
41-60 ft. 12 gauge
61-100 ft. 10 gauge
101-150 ft. 8 gauge

3.6 Wire Your System
3.6.1 Stereo Mode
Typical input and output wiring is shown in
Figure 3.6.
INPUTS: Connect input wiring for each channel.
Refer to Section 3.4 for input connector pin
assignments.
OUTPUTS: Maintain proper polarity (+/-) on
output connectors.
Connect positive (+) speaker lead to Channel 1
positive binding post of amp; connect negative
(–) speaker lead to Channel 1 negative binding
post of amp. Repeat for Channel 2. Refer to
Section 3.5 for output connector pin assignments. Make sure the Mode switch set to the
“Stereo” position when operating in Stereo
mode.
3.6.2 Bridge-Mono Mode
Typical input and output wiring is shown in
Figure 3.7.
INPUTS: Connect input wiring to Channel 1.
Refer to Section 3.4 for input connector pin
assignments.
OUTPUTS: Connect positive (+) speaker lead to
Channel 1 positive binding post of amp; connect
negative (–) speaker lead to Channel 2 positive
binding post of amp. Do not use the negative
binding posts when operating in Bridge-Mono
mode. Refer to Section 3.5 for output connector
pin assignments. Make sure the Mode switch is
set to the “Bridge” position when operating in
Bridge-Mono mode.
NOTE: Turn down (full CCW) the Channel
2 level control when operating in BridgeMono mode, as the Channel 1 level
control works both channels.
