Extron introduced the XPA U 4004 FX four-channel, multi‑zone audio power amplifier. The company says this ENERGY STAR-qualified amplifier can deliver 400 watts simultaneously into 8-ohm, 4-ohm, 70-volt and 100-volt loads, independently configurable per channel. Each channel of an adjacent pair dynamically draws power from the pair’s total wattage, delivering optimal power where it’s needed according to system requirements. Extron says this flexibility allows a single unit to be set up in various configurations to support large systems with multiple speaker types.

Extron says the XPA U 4004 FX features two technologies that provide energy savings. ECO Standby automatically maximizes the time the amplifier operates in its lowest possible power state. At the same time, the Extron exclusive InstaWake+ technology allows the amplifier to return to full power from standby in under 5 milliseconds. InstaWake+ ensures no part of the audio is ever cut off.

The company says the XPA U 4004 FX offers four channels at 400 watts and up to 800 watts per channel at half the channel count. XPA Ultra FX amplifiers are AV designers’ new go-to solutions for multi-zone applications requiring mixed speaker impedances and power levels, according to Extron.
