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: >97 dB
Total Harmonic Distortion (THD) at full bandwidth power, from 20 Hz to 1 kHz: < 0.15%
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

Output Power: (1kHz Power: refers to maximum average power in watts at 1kHz ith 0.1% THD) 2-ohm Stereo (per channer): 570W
4-ohm Stereo (per channer): 400W
8-ohm Stereo (per channer): 260W
Load Impedance: Safe with all types of loads. Rated for 2 to 8 ohms in Stereo, 8 ohms in Bridge-Mono
AC Line Voltages Available (±10%): 120 and 230 VAC
Line Frequency: 50/60 Hz

Controls

Level: Two front-panel, black rotary level controls, one for each channel
Power: Front-panel switch; on when in the UP position
Filter Switches: One per channel; three-position back-panel switches set the frequency for internal high-pass filters. Frequency setting is 30 Hz when switch is in left position; 15 Hz when switch is centered; and bypassed when switch is in right position
Limiter Switch: Back-panel switch offers loudspeaker protection against moderate amplifier clip when set to the “IN” position
Fuse: 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 are provided
Input Impedance (nominally balanced, nominally unbalanced): 20 k ohms, 10 k ohms
Output Connectors:  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, twochannel

Protection

XLS Series amplifiers provide extensive protection and diagnostic capabilities, including built-in anti-clip limiters, switchable high-pass filters, output current limiting, DC protection, fuses, 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), 5.25-inch (13.3-cm) height and 12.6-inch (32.0-cm) depth behind the mounting surface
