K Series Features Tour

Protections

K and KW Series are two of the most robust and trouble free systems available anywhere. First, they benefit from the closed design of an active loudspeaker system, offering more protection of both the amplifier and the transducers than would typically be possible with a component system.

Next, K and KW Series feature QSC Guardrail™ technology, originally introduced on our GX Series amplifiers, which prevents destructive clipping distortion and woofer over excursion.

Heat dispersion is managed by a number of thermal protections including a virtually silent internal fan that engages on-demand during periods when the amp senses high temperatures and turns off when no additional cooling is necessary.

There is also discreet signal limiting technology to prevent overheating of the amplifier and transducers as well as short-circuit protection such as is found on all rugged, reliable QSC amplifiers.
