User manual for the QSC RMX1450a Low-Z Power Amplifier (500 W per Channel) RMX1450A
The user manual for the QSC RMX1450a Low-Z Power Amplifier (500 W per Channel) RMX1450A provides
necessary instructions for the proper use of the product Pro Audio - Live Sound - Power Amplifiers.
The 500 watts per channel 4Ω QSC RMX1450a Low-Z Power Amplifier is a 2RU rack mountable amplifier designed for live sound reinforcement applications. The amplifier features two Class AB output channels that can operate in either stereo or mono bridge mode. The unit operates on a standard 15 amp plug and utilizes high-current toroidal transformers for less noise and better performance when pushing a 2 ohm load. To reduce distortion, the amplifier utilizes independent user-defeatable clip limiters and includes LED indicator lights to show the presence of the signal and when the signal is clipping.
The chassis of the amplifier is designed with front to rear cooling vents and includes selectable low-frequency filters at 30 Hz and 50 Hz to protect speakers from bottoming out and improve headroom when driving mid and high frequencies. The front panel of the unit features two gain control knobs for easy access and each channel is protected by a dedicated DC and thermal overload protection circuit. For inputs, the back of the unit accepts both balanced 1/4" and XLR inputs. For outputs, the unit features both Neutrik Speakon and touch-proof binding post connections.
