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.
