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 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
• Ethernet cables
• Rack for mounting amplier (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.
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 (counterclockwise).
Use a standard 19-inch (48.3 cm) equipment rack (EIA RS-310B). See below figure for amplifier dimensions.
NOTE: When transporting, amplifiers should be supported at both front and back.
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.
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.
