2.1 Unpack and Install 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
• Ethernet 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.
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 2.1 for ampli fier dimensions.
You may also stack amps without using a
rack.
NOTE: When transporting, amplifiers should be
supported at both front and back.
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.

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 on the right side and right
bottom of the amplifier (facing the amplifier).
If an equipment rack is used, we recommend
locating sensitive equipment at least 20 cm
(8 inches) away from the amplifier.
