QSC PL380 Power Amplifier, 2500W @ 4 Ohms

The QSC PL380 Power Amplifier is comprised of our "Ultimate Analog" power house amplifier, designed for the most demanding concert and live-sound reinforcement applications. The PL380 features the ground breaking PowerLight power supply technology, dramatically reducing weight, eliminating AC mains hum and improving audio quality. Comprehensive remote control and monitoring can also be achieved via the Q-SYS networked platform.
