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- or four-conductor, heavy gauge speaker wire and connectors. You may use a 4-pole Speakon

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.

2.6.3 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 a speaker in 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 to terminals 1+ and 2+ in the Speakon connector (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.

2 Setup

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.

2.9 Startup Procedure

Use the following procedure when first turning on your amplifier:

1. Turn down the level of your audio source.

2. Turn down the level controls of the amplifier.

3. Turn on the “Power” switch. The Power indicator should glow.

4. Turn up the level of your audio source to an optimum level.

5. Turn up the Level controls on the amplifier until the desired loudness or power level is achieved.

6. Turn down the level of your audio source to its normal range.

If you ever need to make any wiring or installation changes, don’t forget to disconnect the power cord.

For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.

3 Operation

XLS Series Power Amplifiers

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.

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.

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:

Table 2: Circuit-Breaker Amperage Ratings

100V 120V 220V 240V

XLS 202 7A 7A 7A 7A

XLS 402 10A 10A 7A 7A

XLS 602 10A 10A 7A 7A

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.

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%.

Here are the equations used to calculate the data presented in Figures

7.1, 7.2 and 7.3:

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.

8 Service

XLS Series Power Amplifiers

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

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.
