Extron XPA U 2004 FX Four Channel Configurable Output Audio Power Amplifier 200 Watts Per Channel

Product Description

The Extron XPA U 2004 FX is a four-channel configurable output audio power amplifier that delivers 200 watts per channel simultaneously into 8 ohm, 4 ohm, 70 volt, and 100 volt loads. Engineered for multi-zone commercial AV systems, this Class D amplifier lets integrators independently select an output mode per channel using rear-panel rotary switches, so a single 1U chassis can drive low-impedance speakers and distributed 70V/100V loudspeaker lines at the same time. As a mid-power four-channel configurable output audio power amplifier, the XPA U 2004 FX standardizes amplifier inventory across rooms while conserving rack space.

Flexible power allocation shares the combined 400 watts of each adjacent odd/even channel pair, directing power to the zones that need it most. The fan-cooled aluminum enclosure requires no adjacent empty rack spaces for ventilation, and front and rear rack-mount hardware is included for stability. InstaWake+ auto-standby places the amplifier in a low-power state after inactivity and returns it to full output in under 5 milliseconds with minimal inrush current, so multiple units power up together without sequencing.

Typical deployments include corporate offices, classrooms and lecture halls, houses of worship, retail and hospitality background music, and conference centers where distributed 70V audio coexists with foreground stereo reproduction. The XPA U 2004 FX integrates cleanly with Extron audio processors, matrix switchers, and control systems. For higher-power zones, compare the four-channel XPA U 4004 FX (400 W/ch); for eight low-impedance channels, see the XPA U 758 (75 W/ch), or browse the full Extron collection.

Key Features

• Four 200-Watt Configurable Channels — Each channel delivers 200 watts into 8 ohm, 4 ohm, 70V, or 100V loads with all channels driven simultaneously for multi-zone integration projects.
• Independent Per-Channel Output Modes — Rear-panel rotary switches let installers set each channel for low-impedance or constant-voltage operation, so one amplifier serves rooms with mixed loudspeaker types.
• Flexible Power Allocation — The combined 400 watts of each odd/even channel pair is shared between the two channels to match the SPL requirements of adjacent zones.
• InstaWake+ Auto-Standby — The amplifier enters standby after 25 minutes of inactivity and returns to full output in under 5 milliseconds on signal detection, with minimal inrush current.
• Selectable High Pass Filter — An 80 Hz, 12 dB-per-octave high pass filter can be engaged in 70V or 100V modes to prevent saturation of speaker transformer cores.
• Professional Audio Performance — The amplifier achieves a 100 dB signal-to-noise ratio and THD+N below 0.1 percent across the 20 Hz to 20 kHz band.
• Low Inrush Current Design — Minimal inrush at power-up allows multiple XPA Ultra FX units to start simultaneously without external power sequencing hardware.
• Comprehensive Protection Circuitry — Automatic clip limiting plus thermal, short-circuit, and DC-fault protection safeguard both the amplifier and connected loudspeakers.
• Single Rack Space Enclosure — The fan-cooled 1U full-rack-width chassis needs no adjacent empty rack spaces and ships with front and rear rack-mount brackets.
• Extron Everlast Power Supply — The internal Everlast supply provides worldwide power compatibility and is backed by a 7-year parts and labor warranty.

Frequently Asked Questions

Can the XPA U 2004 FX drive both 70V distributed audio and low-impedance speakers at the same time?

Yes. Each of the four channels is independently configurable for 8 ohm, 4 ohm, 70V, or 100V operation using the rear-panel rotary switches, so a single amplifier can power a low-impedance stereo pair while simultaneously driving 70V or 100V distributed loudspeaker zones.

How much rack space does the amplifier require?

The XPA U 2004 FX occupies a single rack unit (1U) at full rack width. Front-to-rear variable-speed fan cooling means no adjacent empty rack spaces are required, allowing multiple units to be stacked directly in an equipment rack.

Do I need power sequencing hardware for multiple units?

No. The amplifier draws minimal inrush current at power-up, so multiple XPA Ultra FX series amplifiers can be powered on simultaneously without overloading branch circuits and without external power sequencing.

How does this model compare to the XPA U 4004 FX?

Both are four-channel configurable output amplifiers, but the XPA U 2004 FX delivers 200 watts per channel versus 400 watts per channel on the XPA U 4004 FX. Choose the 2004 FX for moderate-SPL zones and the 4004 FX where higher output or longer 70V/100V runs are required.

What warranty and support are included?

The amplifier carries a 3-year parts and labor warranty, and the internal Extron Everlast power supply is covered for 7 years parts and labor. Creation Networks provides pre-sale system design guidance and post-sale support for commercial AV integrators. Explore related models in the Extron collection.
