SPECIFICATIONS
Performance
Sensitivity (for full rated power at 4 ohms):
1.25 Vrms.
Frequency Response (at 1 watt, 22 Hz to
20 kHz): +0 dB, –1 dB.
Signal-to-Noise Ratio (20 Hz to 20 kHz,
inputs terminated):
A-weighted, below rated power: > 100 dB.
No weighting, below rated power: > 95 dB.
Total Harmonic Distortion (THD): < 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: –75 dB.
at 20 kHz: –59 dB.
Input Impedance (nominal): 20 kilohms bal-
anced, 10 kilohms unbalanced.
Output Power: See power charts.
Load Impedance:
XLS 202, 402, 602, 802: 4 to 8 ohms per
channel in Stereo, 8 ohms in Bridge Mono.
XLS 5000: 2 to 8 ohms per channel in Stereo,
4 to 8 ohms in Bridge Mono.
AC Line Voltage and Frequency Confi gura-
tions Available (±10%): 120 VAC 60 Hz, 100
VAC 50/60 Hz, 220 VAC 50 Hz, and 230-240
VAC.
Controls
Level: Two front-panel rotary level con-
trols, one for each channel.
Power: Front-panel switch; on when in the
IN position.
Circuit Breaker: Back-panel breaker provides
overload protection.
Mode Switch: Back-panel switch selects Dual
or Bridge-Mono mode.
Indicators
Signal Presence Indicators: Two green LEDs,
one for each channel, illuminate when the
channel’s input signal exceeds –40 dBu.
Clip Indicators: Two red LEDs, one for each
channel, illuminate when the channel’s output
is being overdriven.
Power Indicator: Blue LED indicates ampli-
fi er has been turned on and AC power is
available.
Fault Indicator: Two red LEDs, one for each
channel, illuminate when amplifi er is in
protect mode. Also illuminates briefl y during
normal power-up when amplifi er is fi rst
switched on.
Input/Output
Input Connectors: One per channel; back-
panel three-pin female XLR input connec-
tors.
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 binding posts per
channel; accepts banana plugs or bare wire.
(European models do not accept banana
plugs.)
Protection
XLS Series amplifi ers provide extensive pro-
tection and diagnostic capabilities, including
output current limiting, DC protection, circuit
breaker, and thermal protection.
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).
