Used QSC Audio Gear for Sale
QSC is best known for two things on the used market: power amplifiers with reputations for running for decades — the PLX, CX, and GX series are staples of touring and install racks — and the K and KW families of powered speakers. On used QSC amps check fan noise and output on both channels under load; on K-series boxes confirm the amp module and DSP presets work, as those are the serviceable parts.
