Extron electronics XPA U 1004 SB, User Manual

XPA U 1004 SB and XPA U 2002 SB • Introduction

3

• 

Ultra low inrush current at power up - no need for power sequencing

 — Allows 

multiple XPA Ultra amplifier to be powered on simultaneously without overloading power 
circuits. This eliminates the need for power sequencing.

• 

Power factor correction - removes harmonic content on AC line

 — The XPA U 

1004 SB and XPA U 2002 SB features power factor correction technology that smooths 
out the high peak currents of the amplifier’s current draw, minimizing the presence of 
high frequency harmonics on the AC power line, preventing audible artifacts from being 
transmitted to other audio equipment in the system.

• 

Rear panel recessed, detented level controls

 — Provides attenuation of input signal 

for adjusting audio system gain staging. These controls are lcoated on the rear panel to 
prevent tampering with the level adjustments. Laser etched markings provide enhanced 
visibility of settings for ease of configuration.

• 

Remote standby port

 — Enables the XPA U 1004 SB and XPA U 2002 SB to be 

remotely powered down when not in use, reducing operating cost.

• 

Automatic clip limiter 

— Detects actual onset of clipping. Gain is automatically 

reduced without audible artifacts to prevent clipping distortion.

• 

Multiple protection circuits 

— Activate during output shorts, thermal overload, or DC 

faults to prevent damage to the amplifier and speakers.

• 

5 mm screw-lock captive screw speaker connectors 

— Enable simple, secure 

connections with 22 to 12 AWG speaker cables.

• 

Front and rear-mounted signal and protection indication LEDs 

— Provide 

convenient indication of input signal presence and protection circuit activation from both 
sides of an equipment rack. 

• 

Front panel over-temperature LED 

— Provides visual indication that the amplifier’s 

temperature has exceeded the optimal value, well in advance of the onset of thermal 
protection circuitry.

• 

Internal Extron Everlast™ power supply 

— Provides worldwide power compatibility, 

with high-demonstrated reliability and low power consumption for reduced operating 
cost.

• 

Extron Everlast Power Supply is covered by a 7-year parts and labor warranty.
