Product Description

The PowerLight 3 Series is based on decades of research and experience in audio power amplification. The PL340 combines the most requested analog input adjustments with easy-to-read LED indicators, making it easy to inspect settings at a glance and match to any system. Because there is no internal digital processing or signal delay, this amp can be combined with all types of traditional amps. The QSC DataPort provides access to QSC's full range of digital processors and remote control monitor systems.

The PL340 continues the PowerLight legacy started in 1994, combining a powerful, lightweight and efficient switchmode supply with QSC’s most advanced Class-H linear output section. Their reference-quality audio performance, high thermal capacity, and touring-grade ruggedness continue to lead the industry.
