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 transpor-

tation company immediately. Only you can ini-

tiate a claim for shipping damage. Crown will

be happy to help. Save the shipping carton as

evidence of damage for the shipper’s inspec-

tion.

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 Instruc-

tions found at the beginning of this man-

ual.

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 (counterclock-

wise).

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 cabi-

net.

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 2 inches (5.1

cm) away from the amplifier sides, and the back

of the rack should be a minimum of 4 inches

(10.2 cm) from the amplifier back panel.
