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.
XLS Series Power Amplifiers
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.

2.4 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
®
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.
Distance Wire Size
up to 25 ft. 16 AWG
26-40 ft. 14 AWG
41-60 ft. 12 AWG

2.7 Connect to AC Mains
Connect your amplifier to the AC mains power source (power outlet) with the supplied AC power cordset. First, connect the IEC end of the cordset to the IEC connector on the amplifier; then, plug the other end of the cordset to the AC mains.
WARNING: The third prong of this connector
(ground) is an important safety feature. Do not attempt to disable this ground connection by using an adapter or other methods.
Amplifiers don’t create energy. The AC mains voltage and current must be sufficient to deliver the power you expect. You must operate your amplifier from an AC mains power source with not more than a 10% variation above or a 15% variation below the amplifier’s specified line voltage and within the specfied frequency requirements (indicated on the amplifier’s back panel label). If you are unsure of the output voltage of your AC mains, please consult your electrician.
2.8 Protecting Your Speakers
It's wise to avoid clipping the amplifier signal. Not only does clipping sound bad, it can damage highfrequency drivers. To prevent clipping, insert a limiter between your mixer output and amplifier input.
That way, no matter how strong a signal your mixer produces, the amplifier will not clip. Set the limiter threshold so that mixer signals above 0 on the mixer meters do not quite drive the amplifier into clipping.
Also, avoid sending strong subsonic signals to the amplifier. High-level, low-frequency signals from breath pops or dropped microphones can blow out drivers. To prevent subsonic signals, insert a highpass filter between mixer output and amplifier input
(or between mixer and limiter). Alternatively, switch in highpass filters at your mixer. Set the filter to as high a frequency as possible that does not affect your program. For example, try 35 Hz for music and
75 Hz for speech. On each mixer input channel, set the filter frequency just below the lowest fundamental frequency of that channel's instrument.

Operation Manual
XLS Series Power Amplifiers
3 Operation
3.1 Precautions
Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:
1.
Before use, your amplifier first must be configured for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties. For information on wiring and configuration, please consult the Setup section of this manual or, for advanced setup techniques, consult Crown’s
Amplifier Application Guide available online at www.crownaudio.com.
2.
Use care when making connections, selecting signal sources and controlling the output level.
The load you save may be your own!
3.
Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.
4. WARNING: Never connect the output to a power supply, battery or power main.
Electrical shock may result.
5.
Tampering with the circuitry, or making unauthorized circuit changes may be hazardous and invalidates all agency listings.
6.
Do not operate the amplifier with the red Clip
LEDs constantly flashing.
7.
Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.
8.
Do not operate the amplifier with less than the rated load impedance. Due to the amplifier’s output protection, such a configuration may result in premature clipping and speaker damage. Operating with a 2-ohm load is not recommended, as the amplifier might shut down.
Remember: Crown is not liable for damage that results from overdriving other system components.

4 Advanced Features and Options
NOTE: For detailed information about these Crown amplifier features, please consult the Crown Amplifier Application
Guide, available on the Crown website at www.crownaudio.com.
4.1 Protection Systems
Your Crown amplifier provides extensive protection and diagnostic capabilities, including output current limiting, DC protection, circuit breaker, and special thermal protection for the unit’s transformers.
4.1.1 Output Current Limiting
Output Current Limiting circuitry protects the amplifier output stage for damage caused by short-circuit loads.
Figure 4.1
Fault Indicator
4.1.2 DC Protection
DC Protection disconnects the loudspeaker load in the event of an output DC offset exceeding 2V. In such an event the yellow Fault LED will illuminate (see Figure 4.1) and both amplifier channels will be muted. In the majority of cases, DC protection is indicative of a faulty amplifier channel, and will be accompanied by an illuminated Clip LED, even with no input connected and level controls set at minimum. If this is the case, contact your dealer or service center.
4.1.3 Circuit Breaker
The high-voltage power supplies of your Crown amplifier are protected by a circuit breaker. The breaker rating varies depending on model and supply voltage as follows:

4.1.4 Thermal Protection
The Thermal Protection circuit will activate if the internal heatsink temperature exceeds proper operating temperatures (194 °F, 90 °C).
When the heatsink temperature has fallen to a safe level, this protection circuit will automatically be reset. Principle causes of thermal protection are:
1) Inadequate ventilation of the equipment rack
2) Incorrect load impedance
3) Output cable short circuit
4) Blocked air vent
5) Heatsinks in need of cleaning
6) Cooling fan failure.
The cause of your amplifier’s thermal protection state should be determined and corrected as soon as possible. Without correction, the Thermal Protection circuit will typically reactivate.

5 Troubleshooting
CONDITION: Normal operation.
POSSIBLE REASON:
• This is normal operation for your amp.
CONDITION: No power to the amplifier.
POSSIBLE REASON:
• The amplifier’s Power switch is off.
• The amplifier is not plugged into the power receptacle.
• The amplifier’s high-voltage power supply circuit breaker has tripped. Verify that the AC mains voltage is correct, then press the Circuit
Breaker button on the back panel.
CONDITION: Distorted sound.
POSSIBLE REASON:
• Input signal level is too high. Turn down your amplifier Level controls. NOTE: Your amplifier should never be operated at a level which caused the Clip LEDS to illuminate constantly.
KEY
CONDITION: No sound.
POSSIBLE REASON:
• The amplifier has just turned on and is still in the 4-second turn-on delay.
• The amplifier is in “fault” mode. A Fault status can be triggered when one of the amplifier’s protection circuits is activated. First disconnect your speakers from the affected channels(s) one by one to determine if one of the loads is shorted. If the indicators return to normal status, then try a different speaker or cable to determine where the short is occurring. If no short can be found, turn off the amp and allow the amp to cool. If indicators do not return to normal after restarting your amp, check the fuse and replace if necessary, or return amp to
Crown or an authorized Crown Service Center for servicing.
• No input signal.
• Input signal level is very low.
• Level controls are turned down.
• Speakers not connected.

7 AC Power Draw and Thermal Dissipation
This section provides detailed information about the amount of power and current drawn from the AC mains by XLS amplifiers and the amount of heat produced under various conditions. The calculations presented here are intended to provide a realistic and reliable depiction of the amplifiers. The following assumptions or approximations were made:
• The amplifier’s available channels are loaded, and full power is being delivered.
• Efficiency at standard 1 kHz power into 4 ohms is 63% for the XLS
602, 57% for the XLS 402, and 49% for the XLS 202.
• Quiescent power draw is 26W for the XLS 602, 23W for the XLS 402, and 19W for the XLS 202.
• XLS 602 quiescent thermal dissipation equals 88 btu/hr at 0 watts with 4 and 8 ohm loads.
• The estimated duty cycles take into account the typical crest factor for each type of source material.
• Duty cycle of pink noise is 50%.
• Duty cycle of highly compressed rock ‘n’ roll midrange is 40%.
• Duty cycle of rock ‘n’ roll is 30%.
• Duty cycle of background music is 20%.
• Duty cycle of continuous speech is 10%.
• Duty cycle of infrequent, short duration paging is 1%.
XLS Series Power Amplifiers
Here are the equations used to calculate the data presented in Figures
7.1, 7.2 and 7.3:
The following equation converts power draw in watts to current draw in amperes:
The value used for Power Factor is 0.86 for the XLS 602, 0.85 for the XLS
402, and 0.87 for the XLS 202. The Power Factor variable is needed to compensate for the difference in phase between the AC mains voltage and current.
The following equation is used to calculate thermal dissipation:
The value used for amplifier inefficiency is (1.00-Efficiency). The factor
3.415 converts watts to btu/hr. Thermal dissipation in btu is divided by the constant 3.968 to get kcal.
If you plan to measure output power under real-world conditions, the following equation may also be helpful:

8 Service
Crown amplifiers are quality units that rarely require servicing. Before returning your unit for servicing, please contact Crown Technical Support to verify the need for servicing.
This unit has very sophisticated circuitry which should only be serviced by a fully trained technician. This is one reason why each unit bears the following label:
CAUTION: To prevent electric shock, do not remove covers. No user serviceable parts inside. Refer servicing to a qualified technician.
8.1 Worldwide Service
Service may be obtained from an authorized service center. (Contact your local Crown/
Amcron representative or our office for a list of authorized service centers.) To obtain service, simply present the bill of sale as proof of purchase along with the defective unit to an authorized service center. They will handle the necessary paperwork and repair.
Remember to transport your unit in the original factory pack.
8.2 US and Canada Service
Service may be obtained in one of two ways: from an authorized service center or from the factory. You may choose either. It is important that you have your copy of the bill of sale as your proof of purchase.
8.2.1 Service at a US or Canada
Service Center
This method usually saves the most time and effort. Simply present your bill of sale along with the defective unit to an authorized service center to obtain service. They will handle the necessary paperwork and repair. Remember to transport the unit in the original factory pack. A
Operation Manual list of authorized service centers in your area can be obtained from the Crown website at www.crownaudio.com, or by calling Crown
Customer Service.
8.2.2 Factory Service
To obtain factory service, fill out the service information page found in the back of this manual and send it along with your proof of purchase and the defective unit to the Crown factory.
For warranty service, we will pay for ground shipping both ways in the United States. Contact Crown Customer Service to obtain prepaid shipping labels prior to sending the unit.
Or, if you prefer, you may prepay the cost of shipping, and Crown will reimburse you. Send copies of the shipping receipts to Crown to receive reimbursement.
Your repaired unit will be returned via UPS ground. Please contact us if other arrangements are required.
8.2.3 Factory Service Shipping
Instructions:
1.
Before sending a Crown product to the factory for service, first call the Crown Service Department for a return authorization
(RA) number.
2.
Be sure to fill out the service information form that follows and enclose it with your shipment, either inside the box or in a packing slip envelope securely attached to the outside of the shipping carton. Do not send the service information form separately. If you are sending the unit from a
Shipping Center, we recommend taping the form to the product. We also recommend recording the serial number and model before shipping for your reference.
3.
To ensure the safe transportation of your unit to the factory, ship it in an original factory packing container. If you don’t have the original carton, you may obtain a product service foam-in-place shipping pack from the Crown Factory Service Department at the number listed below. For nonwarranty service, you may also provide your own shipping pack, however we still recommend using a Crown Supplied Shipping Container. Minimum recommended requirements for materials are as follows:
275 P.S.I. burst test Double-Wall carton that allows for 2-inch solid Styrofoam on all six sides of unit or 3 inches of plastic bubble wrap on all six sides of unit; securely seal the package with an adequate carton sealing tape. Do not use light boxes or “peanuts.” Damage caused by poor packing cannot be covered under warranty.
4.
Do not ship the unit in any kind of cabinet
(wood or metal). Ignoring this warning may result in extensive damage to the unit and the cabinet. Accessories are not needed—do not send the product documentation, cables and other hardware.
If you have any questions, please contact
Crown Factory Service.
