12.Use only with a cart, stand, tripod, bracket, or table specified
by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13.Unplug this apparatus during lightning storms 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 power-supply 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 nor mally, or has been dropped.
15.Use the mains plug to disconnect the apparatus from the mains.
16.WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.
17.DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPLASHING AND ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES, ARE PLACED ON THE EQUIPMENT.

TO COMPLETELY DISCONNECT THIS EQUIPMENT FROM THE AC MAINS, DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE AC RECEPTACLE. THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN READILY OPERABLE.
MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers 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 preamplifi er or other sensitive equipment at the top.

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 compliance could void the user’s authority to operate the equipment.
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 receiver.
•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
Thank you for purchasing the Crown® XLC series amplifier. The XLC2500 and XLC2800 are specially designed for cinema applications. By connecting it to the Crown CXM2000 monitor and crossover system, you can monitor either the processor input signals or the amplifier output signals. You can also see the fault alarms directly on the CXM2000 front panel or TMS (Theater Management System) interface. Together with JBL BC series cinema speakers and Crown CXM2000, Crown XLC series amplifiers offer a perfect cinema audio solution.

2.2 Installing the amplifier
NOTE: 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 (counter-
clockwise).
Use a standard 19-inch (48.3 cm) equipment rack. See Figure 2.2 for amplifier dimensions. You may also stack amplifiers without using a cabinet.
NOTE: Amplifiers should be supported at both the front and rear of the rack.

2.3 Ensuring 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 or rear air vents. The back of the rack should be open.

It is recommended to use the XLC Series amplifiers with the Crown CXM2000 Monitor and Crossover System. Figure 2.4 and figure 2.5 are the samples of wiring XLC amplifiers to the CXM2000 in bi-amplified cinema speakers system and passive cinema speakers system through cables. This allows the CXM2000 to send the audio signals to and receive signals from the XLC amplifiers for crossover, fault detection and monitor functions. More details about the wiring, please read the Operation Manual of the CXM2000 Monitor and Crossover System.
Please see figure 2.6 for the HD-15 pin definition.

2.5 Alternative: Choosing Phoenix Connectors as Input Connectors
Besides connecting the XLC amplifiers to the CXM2000 through HD-15 connector, you can also connect to other input devices through the phoenix connectors on its rear panel. Crown recommends using pre-built or professionally wired balanced line (two-conductor plus shield), 22-24 gauge cables and connectors (see Figure 2.7). Unbalanced lines may be used, but may result in hum or RF noise over long cable runs.
NOTE: Custom wiring should only be performed by qualified personnel.

2.6Choosing Output Wiring and Connectors
Crown recommends using pre-built or professionally wired, high-quality, two-conductor, heavy gauge speaker wire and spade lug connectors or bare wire for your output connectors (Figure 2.8). To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.
Non-Touch cover provides protection of electric shock from the output terminals. Remove it to connect the cables to the output terminals and reinstall it when finish. To reinstall it, insert tab A into the slot right beside the output terminals (see figure 2.9). Put the screw through tab B and screw it into the hole left beside the output terminals (see figure 2.9).
Below are the suggested guidelines to select the appropriate size of wire based on the distance from amplifier to speaker.
