Amplifiers

QSC changed the face of amplifier technology with the introduction of the PowerLightâ„¢ switching power supply, a technological advance that significantly reduces weight and bulk while improving audio performance. PowerLight, first incorporated into the revolutionary PowerLight Series is now used in three other amplifier lines. To get the best sonic performance from your loudspeakers, QSC recommends that you power them with an amplifier that is rated for at least two times the loudspeaker's continuous power rating or equal to the loudspeaker's program power rating. There are seven series of amplifiers carefully designed and manufactured for specific applications from Back Ground Music requirements to Concert Sound needs.   

NEW! PLD/CXD Amplifiers!

The QSC CXD/PLD Series represents a revolutionary advancement in amplifier technology and innovation. This new platform provides efficient, robust and extraordinarily high fidelity power to drive multiple channels and configurations of loudspeakers while simultaneously deploying sophisticated digital processing. 

NEW! CXD 4/3/2/1 Channel DSP Amplifiers 

Designed specifically for the needs of integrators with high performance but optimal energy and rack space efficiency. The CXD Series consists of three powerful, four-channel amplifiers, each with onboard DSP, and the capability to configure and combine channels in various ways to drive a wide range of loudspeaker systems including 70V/100V without the use of transformers. These amplifiers not only provide the power and processing to make your system perform better, they offer outstanding efficiency ensuring that energy costs will be kept to a minimum over the life of the installation.
