The QSC PLX series of power amplifiers are a series of amplifiers that offer a high level of sound quality in a small 2 rack-unit chassis. Thanks to QSC’s signature PowerWave technology, all the amplifiers in the PLX series offer low distortion and a hum free noise floor. This means that the PLX offers the highest quality sound at all frequencies, from low bass to high treble. An advanced thermal management system in the PLX 2402 keeps a consistent reliable sound, and the PLX stays cool even in harsher conditions.
