Operation Manual
This device is designed and evaluated under the condition of 2000 meters tall above sea level; and, it can
≤2000m be only used in locations below 2000 meters tall above
sea level. Using the device above 2000 meters altitude
would result in high safety risk.
The device is designed and evaluated under the condition of non-tropical climate; and, it can be only used
in locations in non-tropical climate areas. Using the
device in tropical climate areas would result in high
safety risk.
IMPORTANT
XLi Series amplifiers require Class 2 output wiring.
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 just above and below the unit.
If an equipment rack is used, we recommend locating the
amplifier(s) in the bottom of the rack and the preamplifier or
other sensitive equipment at the top.
FCC COMPLIANCE NOTICE
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
CAUTION: Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to
operate the equipment.
NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Setup
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 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.
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.
