QSC Audio PLX1804 Professional Power Amplifier

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 offer 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.
