Performance

Sensitivity 

(for full rated power at 4 ohms)

: 

1.4 Vrms.

Frequency Response 

(at 1 watt, 20 Hz to 20 kHz): +0 dB, –1 dB. 

Signal-to-Noise Ratio

Rated as dBr to full rated 8 ohms power 

output (A-weighted): 

XLS1000: > 97 dB. 

XLS1500, XLS2000, XLS2500: > 103 dB.

Total Harmonic Distortion (THD):

(60 Hz and 7 kHz at 4:1) from full rated 

output to –30 dB: < 0.3%.

Damping Factor (8 ohm) 10 Hz to 400 Hz:

> 600.

Crosstalk 

(below rated 8 ohm power)

:

at 1 kHz:  > 85 dB. 

at 20 kHz:  > 60 dB. 

Input Impedance 

(nominal)

:

20 kilohms balanced, 10 kilohms unbalanced.

Load Impedance:

 2 to 8 ohms per channel in 

Stereo, 4 to 8 ohms in Bridge Mono.

AC Line Voltage and Frequency 

Configurations Available (±10%): 

120 VAC 

60 Hz, 100 VAC 50/60 Hz, 220 and 240 VAC 

50 Hz. 

Controls

Level:

 Two front-panel rotary level controls, 

one for each channel.

LCD Screen:

 Back-lit LCD allows for 

crossover configuration, amp mode 

configuration and clip compressor 

configuration.

Menu/Prev/Select:

 Three buttons located 

near the LCD screen that are used to 

configure and access the integrated 

processing.

Power:

 Front-panel switch; on when in the IN 

position. Blue LED will illuminate when on.

Circuit Breaker:

 Back-panel breaker provides 

overload protection.

PureBand

TM

 Crossover System

Crossover Filter:

Linkwitz-Riley 24dB per ocatve.

Crossover Mode:

Crossover (CH1=LPF, CH2=HPF), 

Low Pass (both channels LPF), 

High Pass (both channels HPF), 

Bridge (LPF or HPF).

Peak

X

TM 

Limiters:

 Channel independent clip 

limiter designed to provide maximum output 

while protecting your loudspeakers.

Indicators

Signal Presence Indicators:

 Two green LEDs, 

one for each channel, illuminate when the 

channel’s input signal exceeds –40 dBu.

–10 Indicator:

 Green LED flashes when 

output signal exceeds –10 dB below clip.

–20 Indicator:

 Green LED flashes when 

output signal level exceeds –20 dB below clip.

Clip Indicators:

 Two red LEDs, one for each 

channel, illuminate when the channel’s output 

is being overdriven.

Thermal Indicator:

 Two red LEDs, one 

for each channel, illuminate when thermal 

compression begins.

Input/Output

Input Connectors:

 XLR (one per channel), 

1/4 inch (one per channel), and RCA (one per 

channel). The 1/4 inch inputs can be used 

as loop-thrus to distribute signal to multiple 

amplifiers.

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 amplifiers provide extensive 

protection 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).

Dimensions:

EIA Standard 19-inch (48.3-cm) 

rack mount width (EIA RS-310-B), 3.5-inch 

(8.9-cm) height.
