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

2 Setup
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.

2 Setup
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.
2.5 Choose Output Wire and Connectors
Crown recommends using pre-built or professionally wired, highquality, two-conductor, heavy gauge speaker wire and connectors.
You may use 2-pole or 4-pole Speakon
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

2.6.2 Bridge-Mono Mode
INPUTS: Use a custom “Y” adapter cable, wired
to split the signal and invert the polarity for the
Channel 2 amplifier input as shown in Figure
2.10. We recommend you label the ends of the Y
adapter to help make sure to connect the correct
end to each amplifier input.
Connect the Y adapter between the signal source
and each amplifier input (Figure 2.11).
NOTE: Crown provides a reference of wiring pin
assignments for commonly used connector
types in the Crown Amplifier Application Guide
available at www.crownaudio.
OUTPUTS: There are two ways to wire the amplifier output connectors for Bridge-Mono mode:
1) Wire the speaker across the red binding post
of each channel (Figure 2.11). Do not use the
black binding posts when the amp is being operated in Bridge-Mono mode.
2) Wire the speaker only to the top Speakon connector as shown in Table 3 and Figure 2.12.
NOTE: The Channel 1 and 2 level controls
MUST be set to identical settings when
operating the XLS amplifier in BridgeMono mode.
