or when unused for long periods of time.
14) Refer all servicing to qualified service personnel. Servicing is required when the apparatus
has been damaged in any way, such as powersupply cord or plug is damaged, liquid has
been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to
rain or moisture, does not operate normally,
or has been dropped.
15) To reduce the risk of fire or electric shock, do

IMPORTANT
XLS 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.
WATCH FOR THESE SYMBOLS:
The lightning bolt triangle is used to alert the user
to the risk of electric shock.
The exclamation point triangle is used to alert the
user to important operating or maintenance instructions.
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
complicance could void the user’s authority to operate the euqipment.
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 rece iver.
• 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.

1 Welcome
The XLS Series of power amplifiers from Crown
represents a new era in affordable, quality
power amplification. The line consists of three
models in a uniform, rugged chassis, incorporating the best of tried-and-true design principles and innovative features.
Modern power amplifiers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.
In addition, XLS Series amplifiers include a
number of features which require some explanation before they can be used to their maximum advantage.
Please take the time to study this manual so
that you can obtain the best possible service
from your amplifier.
1.1 Features
•Simple, reliable design incorporates many
popular features.
•Housed in a rugged, all-steel 2U chassis.
•Efficient forced-air fan prevents excessive
thermal buildup.
•Electronically balanced XLR inputs. Touchproof binding post and Speakon
®
outputs.
•Features precision detented level controls,
power switch, and four LEDs which indicate
clip for each channel, power and fault conditions.
1.2 How to Use This Manual
This manual provides you with the necessary
information to safely and correctly setup and
operate your amplifier. It does not cover every
aspect of installation, setup or operation that
might occur under every condition. For additional information, please consult Crown’s
Amplifier Application Guide (available online at
www.crownaudio.com), Crown Technical Support, your system installer or retailer.
We strongly recommend you read all instructions, warnings and cautions contained in this
manual. Also, for your protection, please send
in your warranty registration card today. And
save your bill of sale — it’s your official proof
of purchase.

Operation Manual
2.1 Unpack Your Amplifier
Please unpack and inspect your amplifier for
any damage that may have occurred during
transit. If damage is found, notify the 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
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.
2.2 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 (counterclockwise).
Use a standard 19-inch (48.3 cm) equipment
rack (EIA RS-310B). See Figure 2.1 for amplifier dimensions.
You may also stack amps without using a
cabinet.
NOTE: When transporting, amplifiers should be
supported at both front and back.
2.3 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.
Figure 2.2 illustrates standard amplifier airflow.

Operation Manual
2.4 Choose Input Wire
and Connectors
Crown recommends using pre-built or professionally wired balanced line (two-conductor plus shield), 22-24 gauge cables and
connectors. You should use 3-pin male XLR cable ends at the
amplifier inputs. Unbalanced line may also be used but may
result in noise over long cable runs.
Figure 2.3 shows connector pin assignments for balanced wiring,
and Figure 2.4 shows connector pin assignments for unbalanced
wiring.
NOTE: Custom wiring should only be performed by
qualified personnel.

2 Setup
2.5 Choose Output Wire and Connectors
Crown recommends using pre-built or professionally wired, highquality, two- or four-conductor, heavy gauge speaker wire and
connectors. You may use a 4-pole Speakon
®
connector (Figure
2.5 and Table 1) or banana plugs, spade lugs, or bare wire for
your output connectors (Figure 2.6). To prevent the possibility of
short-circuits, wrap or otherwise insulate exposed loudspeaker
cable connectors.
Note: Binding post outputs on European models come
with safety plugs installed to prevent European powercord plugs from being inserted. The top & bottom entry
positions for these connectors should therefore be used
with European models.
Using the guidelines below, select the appropriate size of wire
based on the distance from amplifier to speaker.
Distance Wire Size
up to 25 ft. 16 AWG
26-40 ft. 14 AWG
41-60 ft. 12 AWG
61-100 ft. 10 AWG
101-150 ft. 8 AWG
151-250 ft. 6 AWG
CAUTION: Never use shielded cable for output wiring.

Typical input and output wiring is shown in
Figure 2.7
INPUTS: Connect input wiring for both channels.
OUTPUTS: Maintain proper polarity (+/–) on
output connectors.
Connect Channel 1 loudspeaker’s positive (+)
lead to Channel 1 positive (red) terminal of amp;
repeat for negative (–). Repeat Channel 2 wiring
as for Channel 1.

connector as shown in Figure 2.8.
or
2) Wire speaker 1 to the amplifier’s Speakon
