Features

• Two channels of 100 watts at 8 ohms or 4 ohms
  Two channels of 100 watts at 70/100V — All channels driven
• ENERGY STAR^® qualified amplifier — The XPA U 1004C is an ENERGY STAR qualified amplifier and energy efficient product that conserves energy and reduces costs.
• Auto standby saves energy — The XPA U 1004C meets 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. Auto-standby can be disabled if required.
• InstaWake™ exits auto-standby mode in under 100 milliseconds — The XPA U 1004 SB quickly returns to full power in less than 100 ms upon signal detection, with minimal inrush current.
• Convection cooled, fanless operation - can be stacked without extra rack space for ventilation — The XPA U 1004C does not require internal fans or vents for cooling, ensuring quiet, reliable operation. It generates substantially less heat than conventional power amplifiers, making it ideal for rack-mount applications where space is at a premium.
• Four channels in a 1U, half rack width enclosure - single and dual rack mount hardware included — The channel density of the XPA U 1004C reduces rack space requirements for many installations. The included single and side by side rack mount hardware simplifies planning and saves cost.
• UL 2043 plenum rated when used with optional Flexible Conduit Adapter Kit — The XPA U 1004C meets 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, part # 70-228-02. Above-the-ceiling placement conceals the amplifier to prevent theft, and is convenient for installing equipment when space inside the room is limited.
• 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 characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive AV equipment such as wireless microphones.
• Professional grade signal-to-noise and THD+N performance — The XPA U 1004C delivers 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 XPA U 1004C 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 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 — Activate during output shorts, thermal overload, or DC faults to prevent damage to the amplifier and speakers.
• Remote standby port — Enables the XPA U 1004C to be remotely powered down when not in use, reducing operating cost.
• High pass filter for high impedance channels — This selectable filter, available on the 70V and 100V channels, 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 enclosure 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
• TAA Compliant version available — Please inform your local Extron representative if your order requires compliance with TAA regulations.
