Description


The compact PLX1804 brings the same performance and technology as the rest of the PLX2 Series, plus even greater value, to applications that don't require bridged or 2 ohm operation. Designed to power one or two speakers from each amplifier channel (4 ohm minimum loading), this model offers a simplified feature set while retaining genuine, uncompromised PLX performance and technology. Weighing just 13 pounds (5.9 kg), the "plug-and-play" PLX1804 is perfect for ultra-portable rigs, as well as reference-quality playback.
