Xs 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.
Xs 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. At the amplifier inputs, use either: • 3-pin male XLR cable ends, • TRS or TS 1/4" phone plugs, or • Phoenix-style connectors. Unbalanced lines may be used, but may result in noise over long cable runs. Figure 2.3 shows XLR wiring, Figure 2.4 shows 1/4" phone plug wiring, and Figure 2.
Xs Series Power Amplifiers 2 Setup 2.6 Wire Your System 2.6.1 Stereo Mode Typical input and output wiring is shown in Figures 2.8 and 2.9. INPUTS: Connect input wiring for both channels. OUTPUTS: Connect speakers to the 5-way binding posts or to the two Speakon® connectors. See the details below. Connection to 5-way binding posts: 1. Connect speaker 1 positive (+) lead to the amp’s Channel-1 positive (red) binding post. CHANNEL 2 2.
Xs Series Power Amplifiers 2 Setup 2.6.3 Bridge-Mono Mode Typical input and output wiring is shown in Figure 2.10. 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: Connect the speaker across the red binding posts of each channel. Do not use the black binding posts when the amp is being operated in Bridge-Mono mode. IMPORTANT: Set the Bridge/Normal switch to “Bridge.
Xs 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. The AC Mains indication light on the front panel should be lit. WARNING: The third prong of this connector (ground) is an important safety feature.
Xs 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.
Xs Series Power Amplifiers 3 Operation 3.2 Front Panel Controls and Indicators E. AC Mains Indicator I. Temp Indicator A. Cooling Vents Red LED indicates that AC power is present at the power cord, even if the amplifier is not turned on. Red LED, one for each channel, indicates that channel(s) are in thermal protect mode. Front-to-rear forced airflow. F. Fault Indicator J. Power Switch B. Gain Controls Two or four grey rotary level controls, one for each channel.

See Figure 2.5 and Table 1 for connector wiring. B. Normal/Bridge Switch Two-position switch selects between normal (stereo) operation and Bridge-Mono operation. C. Circuit Breaker Provides overload protection. D. XLR-1/4" Combo Input Connectors F.
Xs 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 Protection Systems Your Crown amplifier provides extensive protection and diagnostic capabilities, including output current limiting, microprocessor-controlled DC protection, circuit breaker, and special thermal protection for the unit’s transformers. 4.1.
Xs Series Power Amplifiers 5 Troubleshooting CONDITION: No sound. CONDITION: Normal operation. POSSIBLE REASONS: 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 channel (s) one by one to determine if one of the loads is shorted.
