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 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 Instruc-
tions 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 the 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 (EIA RS-310B). See Figure 3.1 for ampli-
fier 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, rear or side 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.
