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 (2-channel models only). Unbalanced lines may be used, but may result in noise over long cable runs. Figure 2.3 shows XLR wiring, Figure 2.

Xs Series Power Amplifiers 2 Setup NOTE: In Bridge-Mono mode, only the Channel 1 Level control is functional. 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.
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.

Normal/Bridge Switch (one per channel pair) One per channel, XLR-1/4" combo connector includes 3-pin female XLR connector and TRS 1/4" phone jack. Accepts balanced or unbalanced signals. Two-position switch selects between normal (stereo) operation and Bridge-Mono operation. D. 5-Way Binding Post Output Connectors B. Circuit Breaker One pair per channel; accept banana plugs, spade lugs or bare wire.
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. Figure 4.
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 channels(s) one by one to determine if one of the loads is shorted.
