Performance
- Sensitivity (volts RMS) for full rated power at 4 ohms:
XLS-202: 0.725V
XLS-402: 1.025V
XLS-602: 1.260V
- 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 per channel in Stereo, 8 ohms in Bridge Mono.
- AC Line Voltage and Frequency Configurations Available (±10%): 120VAC/60 Hz and 230VAC/50 Hz.
Controls
- Level: Two 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: Two front-panel red LEDs, one 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: One per channel; backpanel three-pin female XLR input connectors.
- Input Impedance (nominal): 20 k ohms balanced, 10 k ohms unbalanced.
- Output Connectors: Two 4-Pole Speakon® Output Connectors accept 2-pole or 4-pole Speakon connectors. The top Speakon connector is wired for both channels so it can be used for bridge-mono wiring or for stereo wiring of two speakers to a single Speakon connector.
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, two-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-inch (48.3-cm) rack mount width (EIA RS-310-B), 3.5-inch (8.9-cm) height and 14-inch (35.6-cm) depth behind the mounting surface.
Weight
- Net Weight:
XLS-202: 21.0 lbs. (9.5 kg)
XLS-402: 25.3 lbs. (11.5 kg)
XLS-602: 27.2 lbs. (12.3 kg)
