Nor does it cover every possible situation which may arise during installation, operation or maintenance. [. . . ] 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. 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. page 12 Operation Manual XLS Series Power Amplifiers 3 Operation 3. 2 Front Panel Controls and Indicators A. Clip Indicators Two red LEDs, one for each channel, illuminate when the channel's output signal is being overdriven. Power Indicator Green LED indicates amplifier has been turned on and AC power is available. Fault Indicator Yellow LED illuminates when amplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on. Power Switch Amplifier is on when the switch is in the UP position. Figure 4. 1 Front Panel Controls and Indicators Operation Manual page 13 XLS Series Power Amplifiers 3 Operation 3. 3 Back Panel Controls and Connectors G. Balanced XLR Inputs Two 3-pin female XLR input connectors are provided (one per channel). 5-Way Binding Post Output Jacks One pair per channel; accept banana plugs, spade lugs or bare wire. Note: Binding post outputs on European models come with safety plugs installed to prevent European power-cord plugs from being inserted. The top & bottom entry positions for these connectors should therefore be used with European models. 4-Pole Speakon Output Connector One connector is used for the two output channels. See Page 6, Figure 2. 5 and Table 1 for connector wiring. Figure 4. 1 Back Panel Controls and Connectors page 14 Operation Manual 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 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. 4. 1. 3 Circuit Breaker The high-voltage power supplies of your Crown amplifier are protected by a circuit breaker.
