Crown XS 500 Description:

The Xs Series of power amplifiers from Crown represents a new era in affordable, quality power amplification. The line consists of four models in a uniform, rugged 2U chassis, incorporating the best of tried-and-true design principles and innovative features.

Crown XS 500 Features:

• Housed in a rugged, all-steel 2U chassis.
• Efficient forced-air fan prevents excessive thermal buildup.
• XLR-1/4" combo inputs, 3-pin Phoenix-style inputs, daisy-chain XLR outputs, touch-proof binding post outputs and Speakon outputs.
• Precision detented level controls, power switch, and five LEDs which indicate clip for each channel, power, AC mains, temperature and fault conditions.
• Microprocessor-controlled protection system.
• Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications.

• Controls
• Level: Two or four front-panel, gray rotary level controls, one for each channel.
• Power: Front-panel switch; on when in the right-hand position.
• Indicators
• Signal: Two or four green LEDs, one for each channel, illuminates when the channels input signal level is above 40 dBu.
• Clip: Two or four front-panel red LEDs, one for each channel, illuminates when the channels output signal is being overdriven.
• Power: Yellow front-panel LED indicates amplifier has been turned on and AC power is available.
• AC Mains: Red front-panel LED indicates the presence of AC power at the power cord, even if the amplifier is not turned on.
• Fault: Red front-panel LED illuminates when amplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on.
• Bridge: Yellow LED indicates that amplifier is in bridge mode (Channels 1 and 2, Channels 3 and 4 in Xs 4300).
• Temp: Red LED indicates that channel(s) are in thermal protect mode.
• Input/Output
• Input Connectors:
• XLR-1/4" combo connectors: One per channel, 3-pin female XLR connector and TRS 1/4" phone jack accept balanced or unbalanced signals.
• 3-pin Phoenix-style connectors (2-channel models only): One per channel, accepts balanced or unbalanced signals.
• Input Impedance (nominal) balanced, unbalanced: 20 k ohms, 10 k ohms.
• Output Connectors:
• Balanced XLR connectors (2-channel models only): One per channel, 3-pin male XLR connector in parallel with XLR-1/4" combo and Phoenix-style input connectors for daisy-chain operation.
• 5-Way binding post output connectors: 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 (2-channel models only): One connector per channel. Accepts a 4-pole Speakon connector.
• DC Output Offset (shorted input): < 75 millivolts.
• Output Signal: Stereo, unbalanced, two-channel or four-channel (Xs4300 only)
