QSC RMX 1450

The QSC RMX 1450 Power Amp combines rugged high-output design with the latest circuit technology to deliver unmatched performance at a breakthrough price. RMX power amps require only 2 rack spaces and feature 1/4″ TRS, XLR, and barrier strip balance inputs; binding post and Neutrik Speakon outputs; front-mounted gain controls for easy access; independent and defeatable clip limiters; selectable low-frequency filters (30Hz or 50Hz) that protect speakers and increase headroom; signal and clip LED indicators; independent DC and thermal overload protection on each channel; variable-speed fan. All include a 3-year warranty. Stereo: 280W @ 8 ohms, 450W @ 4 ohms, and 700W @ 2 ohms. Bridge mono: 900W @ 8 ohms, 1400W @ 4 ohms.
