QSC CX254 4-Channel Professional Power Amplifier withPower Cord

  

All the functions have been tested and are in working order. The amplifier has some scuffs, scratches and other signs of use. No other accessories are included unless shown in the photos. Details from QSC product specs on their website. Compact size - only 2 RU and 14 deep for reduced rack cost and floor space.

Bridgeable channels 1 + 2 and 3 + 4, for maximum flexibility. Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers.

HD15 DataPort connector for Q-SYS networked control and monitoring. Custom integrated security cover for tamper-proof installations.

Variable-speed fan for low noise. 1-dB detented gain controls for fast and accurate gain settings. Detachable Euro style input connectors. DIP switch control for clip limiters, high pass filters, bridge mono and parallel operation.

Exclusive PowerLight switch-mode power supply technology for high performance and compact size. Selectable high-pass filters protect speakers and prevent speaker transformer saturation with minimal effect on program material (33 Hz or 75 Hz). Comprehensive front panel indicators including signal, clip, protect and QSC's exclusive bridge mono and parallel input LEDs. Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection. High-performance Class AB+B complementary bipolar output circuitry.
