 QSC Series Power Amplifiers |
|
The QSC RMX 1450 Power Amp combines their rugged high-output designs with the latest circuit technology to deliver unmatched performance at a breakthrough price. The RMX amps require only 2 rackspaces 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. |
