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.

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.

XLS Series Power Amplifiers
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.

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
Balanced Input
Connector Wiring
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® connectors (Figure 2.5 ) 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.

2.6 Wire Your System
2.6.1 Stereo Mode
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.
Figure 2.7 shows how to wire stereo speakers to the 5-way binding posts.
To wire stereo speakers to the Speakon® connectors, use one of these methods:
Method 1 (Table 1 and Figure 2.8): Wire one Speakon cable connector to two speakers. Insert the Speakon cable connector into the amplifier’s top Speakon connector.
Method 2 (Table 2 and Figure 2.9): Plug the Channel 1 speaker into the Channel 1 (top) Speakon connector, and plug the Channel 2 speaker into the Channel 2 (bottom) Speakon connector.

Stereo Wiring Method 1: Use Top Speakon Only

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.
