QSC CX254 4 CHANNEL POWER AMP. Good condition removed and tested from working store music system rack that was remodeled. Clip is missing on upper top connector from due to transporting unit. No cables are included, power supply and and amp unit only.
Details from QSX 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.
