XLS Series Power Amplifiers 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.
XLS Series Power Amplifiers 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 Balanced Input Connector Wiring Figure 2.3 shows connector pin assignments for balanced wiring, and Figure 2.
XLS Series Power Amplifiers 2 Setup 2.6 Wire Your System 2.6.1 Stereo Mode Using the 5-way Binding Posts 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.
XLS Series Power Amplifiers 2 Setup 2.6.2 Stereo Mode Using the Speakon® Connector There are two ways to wire two speakers in stereo to the amplifier’s Speakon® connector. 1) Wire the two speakers to the same Speakon® connector as shown in Figure 2.8. or Figure 2.8 Speakon® Stereo Wiring Option 1: Wire Two Speakers to One Speakon® Connector 2) Wire speaker 1 to the amplifier’s Speakon® connector, and wire speaker 2 to speaker 1 (Figure 2.9). SPEAKER 1 SPEAKER 2 AMPLIFIER Figure 2.
XLS Series Power Amplifiers 2 Setup 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).
XLS Series Power Amplifiers 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. 2.9 Startup Procedure Use the following procedure when first turning on your amplifier: WARNING: The third prong of this connector (ground) is an important safety feature.
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.

Balanced XLR Inputs Two 3-pin female XLR input connectors are provided (one per channel). J. Fans Provide front-to-back forced airflow for cooling. K. 5-Way Binding Post Output Jacks One pair per channel; accept banana plugs, spade lugs or bare wire.
XLS Series Power Amplifiers 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. 4.1.3 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.
XLS Series Power Amplifiers 5 Troubleshooting CONDITION: Normal operation. CONDITION: No sound. POSSIBLE REASON: 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.
