Extron has released the XPA U 4004 FX four-channel, multi‑zone audio power amplifier.

The Energy Star-qualified, high-performance amplifier can deliver 400W simultaneously into 8Ω, 4Ω, 70V and 100V loads, independently configurable per channel with each channel of an adjacent pair dynamically drawing power from the pair’s total wattage, delivering optimal power where it’s needed according to system requirements.

“Designing a high power amplifier that honours our commitment to efficiency and energy savings is challenging,” Extron chief marketing officer Casey Hall says.

“The introduction of ECO Standby with InstaWake+ in the XPA U 4004 FX represents a no-compromise solution for our valued customers who have leading-edge system requirements.”

The XPA U 4004 FX features two exclusive technologies that work together to provide energy savings.

ECO Standby automatically maximises the time the amplifier operates in its lowest possible power state, while the Extron exclusive InstaWake+ technology gives the amplifier the ability to return to full power from standby in under 5ms. InstaWake+ ensures no part of the audio is ever cut off.

The XPA U 4004 FX offers four channels at 400W and up to 800W per channel at half the channel count. XPA Ultra FX amplifiers are AV designers’ new go-to solutions for any multi-zone application requiring mixed speaker impedances and power levels.

The exceptional flexibility of the XPA U 4004 FX allows a single unit to be set up in a variety of configurations to support large systems with multiple speaker types.
