SPECIFICATIONS
Performance
Sensitivity (volts RMS) for full rated power at 4
ohms: 1.25 V.
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: –50 dB.
Input Impedance (nominal): 20 kilohms balanced,
10 kilohms unbalanced.
Output Power: See power charts on previous
page.
Load Impedance: Rated for 4 to 8 ohms per chan-
nel in Stereo, 8 ohms in Bridge Mono.
AC Line Voltage and Frequency Configurations
Available (±10%): 120 VAC 60 Hz, 100 VAC 50/60
Hz, 220 VAC 50 Hz, and 230-240 VAC .
Front Panel Controls and Indicators
Level: Two front-panel rotary level controls, one
for each channel.
Power: Front-panel switch; on when in the IN
position.

Circuit Breaker: Back-panel breaker provides over-
load protection.
Mode Switch: Back-panel switch selects Dual or
Bridge-Mono mode.
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 chan-
nel, illuminate when the channel’s output is being
overdriven.
Power Indicator: Blue LED indicates amplifier
has been turned on and AC power is available.
Fault Indicator: Two red LEDs illuminate when
amplifier is in protect mode. Also illuminates briefly
during normal power-up when amplifier is first
switched on.
Back Panel Connectors
Input Connectors: One per channel; back-panel
three-pin female XLR input connectors.
Output Connectors: Two 4-Pole Speakon
®
Output
Connectors accept 2-pole or 4-pole Speakon con-
nectors. 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 binding posts per channel; accepts
banana plugs or bare wire. (European models do
not accept banana plugs.)
Protection
XLS Series amplifiers provide extensive protection
and diagnostic capabilities, including output current
limiting, DC protection, circuit breaker, and thermal
protection.
Cooling
Internal heat sinks with forced-air cooling for rapid,
uniform heat dissipation. Flow-through ventilation
from front to back.
Dimensions
EIA Standard 19-inch (48.3-cm) rack mount width
(EIA RS-310-B), 3.5-inch (8.9-cm) height and 15.2-
inch (38.6-cm) depth.
