Features:

• Reliable design incorporates many popular features

• Selectable high-pass filter on each channel enables amplifier to work more efficiently when full bandwidth is not required

• Pair of linear optocoupler clip limiters protects loudspeakers from being overdriven

• Housed in a rugged, all-steel 2U chassis

• Efficient forced-air fan prevents excessive thermal buildup

• Electronically balanced XLR inputs and touch-proof binding post outputs

• Features precision detented level controls, power switch, and 4 LEDs, which indicate clip for each channel, power and fault conditions

Specifications

• Power (1 kHz power):
  • 2-ohm stereo (per channel): 250W
  • 4-ohm stereo (per channel): 200W
  • 8-ohm stereo (per channel): 145W

The following applies to units in Stereo mode with 8-ohm loads and rated input sensitivity unless otherwise specified.

• Performance
  • Sensitivity (volts RMS) for full rated power at 4 ohms: 0.725
  • Frequency Response (at 1 watt) 20 Hz to 20 kHz: ±0.75 dB
  • Phase Response (degrees at 1 watt)

at 10 Hz: –10. at 20 kHz: +19.

• • Signal-to-Noise Ratio (20 Hz to 20 kHz)
  • A-weighted, below rated power: > 100 dB
  • No weighting, below rated power: > 95 dB
  • Total Harmonic Distortion (THD) at full bandwidth power, from 20 Hz to 1 kHz: < 0.5%
  • Intermodulation Distortion (IMD) (60 Hz and 7 kHz at 4:1) from full rated output to –40 dB: < 0.3%
  • Damping Factor (8 ohm) 10 Hz to 400 Hz: >200
  • Crosstalk (below rated power)

at 1 kHz: –82 dB. at 20 kHz: –58 dB

• • Voltage Gain (at maximum output): 31 dB

• Power
  • Load Impedance: Safe with all types of loads. Rated for 2 to 8 ohms in Stereo, 8 ohms in Bridge-Mono
  • AC Line Voltage : 120VAC, 60 Hz

• Controls
  • Level: 2 front-panel, black rotary level controls, one for each channel
  • Power: Front-panel switch; on when in the UP position
  • Circuit Breaker: Provides overload protection

• Indicators
  • Clip: 2 front-panel red LEDs, 1 for each channel, illuminate when the channel’s output signal is being overdriven
  • Power: Green front-panel LED indicates amplifier has been turned on and AC power is available
  • Fault: Yellow front-panel LED illuminates when amplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on.

Input/Output

• Input Connectors: 1 per channel; back-panel 3-pin female XLR input connectors are provided.
• Input Impedance: (nominally balanced, nominally unbalanced): 20 k ohms, 10 k ohms
• Output Connectors: One 4-pole Speakon connecotr and one pair of back-panel, 5-way binding posts per channel; accepts banana plugs, spade lugs or bare wire. (European models do not accept banana plugs.)
• DC Output Offset (shorted input): ±10 millivolts
• Output Signal: Stereo, unbalanced, 2-channel

Protection

• XLS Series amplifiers provide extensive protection and diagnostic capabilities, including output current limiting, DC protection, circuit breaker, and special thermal protection for the unit’s transformers.

Construction

• Ventilation: Flow-through ventilation from front to back.
• Cooling: Internal heat sinks with forced-air cooling for rapid, uniform heat dissipation.
• Air Volume Requirements (per minute per unit): 80.15 ft³ (2.27 m³)
• Dimensions: EIA Standard 19 in. (48.3-cm) rack mount width (EIA RS-310-B), 3.5 in. (8.9-cm) height and 14 in. (35.6-cm) depth behind the mounting surface.
