Terms Used in this Manual
Features
The terms “amplifier” and “power amplifier” are used interchangeably in this manual to refer
to all of the XPA Ultra models.
• Output Power
• XPA U 358 models — 35 watts rms output power per channel, all channels driven.
• XPA U 1004 models — 100 watts rms output power per channel, all channels
driven.
• XPA U 1002 models — 100 watts rms output power per channel, all channels
driven.
• ENERGY STAR® qualified amplifiers — The XPA Ultra Series are ENERGY STAR
qualified amplifiers and energy efficient products that conserve energy and reduce
costs.
XPA Ultra Series Power Amplifiers • Introduction 1
• Extron Patented CDRS - Class D Ripple Suppression — CDRS is an Extron
Patented technology that provides a smooth, clean audio waveform and an
improvement in signal fidelity over conventional Class D amplifier designs. CDRS
eliminates the high frequency switching ripple characteristics of Class D amplifiers,
a source of RF emissions which can interfere with sensitive AV equipment such as
wireless microphones.
• Convection cooled, fanless operation - can be stacked without extra rack
space for ventilation — The XPA Ultra Series amplifiers do not require internal fans
or vents for cooling, ensuring quiet, reliable operation. They generate substantially less
heat than conventional power amplifiers, making them ideal for rack-mount applications
where space is at a premium.
• Eight channels (XPA U 358 models), four channels (XPA U 1004 models), or two
channels (XPA U 1002 models) in a 1U, half rack width enclosure - single and
dual rack mount hardware included — The channel density of the XPA Ultra Series
amplifiers reduce rack space requirements for many installations. The included single
and side by side rack mount hardware simplifies planning and saves cost.
• Defeatable auto-standby with fast wake up — The XPA Ultra Series amplifiers
meet ENERGY STAR qualification requirements with an auto-standby feature that
automatically places the amplifier into standby after 25 minutes of inactivity, dramatically
reducing power consumption. The XPA Ultra Series amplifiers quickly return to full
power status in less than 100 ms upon signal detection, with minimal inrush current.
Auto-standby can be disabled if required.
• UL 2043 plenum rated when used with optional Flexible Conduit Adapter
Kit — The XPA Ultra Series amplifiers meet UL 2043 for smoke and heat release for
installation within a plenum airspace above a drop ceiling when used with the optional
Flexible Conduit Adapter Kit. Above-the-ceiling placement conceals the amplifier to
prevent theft, and is convenient for installing equipment when space inside the room is
limited.
• Professional grade signal-to-noise and THD+N performance — The
XPAUltraSeries amplifiers deliver professional grade performance, featuring 100 dB
signal-to-noise ratio and THD+N of less than 0.1%.
• Ultra low inrush current at power up - no need for power sequencing —
Allows multiple XPA Ultra Series amplifiers 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
XPAUltraSeries amplifiers feature power factor correction technology that smooths
out the high peak currents of the amplifiers’ 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
signals for adjusting audio system gain staging. These controls are located on the rear
panel to prevent tampering with level adjustments. Laser etched markings provide
enhanced visibility of settings for ease of configuration.
• Automatic clip limiter — Detects actual onset of clipping. Gain is automatically
reduced without audible artifacts to protect speakers from clipping distortion.
• Multiple protection circuits — Active during output shorts, thermal overload, or DC
faults to prevent damage to the amplifier and speakers.
• Remote standby port — Enables the XPA Ultra Series amplifiers to be remotely
powered down when not in use, reducing operating cost.
XPA Ultra Series Power Amplifiers • Introduction 2
• High pass filter for high impedance models — This selectable filter, available on the
XPA Ultra Series high impedance models, rolls off frequencies below 80 Hz to prevent
saturation of speaker transformers.
• 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
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.
