QSC RMX-1850 HD

QSC Audio Products introduces the RMX 1850HD 2-channel power amp. Like all RMX amplifiers it offers value and performance capability that will appeal to performing musicians, mobile DJs, and anyone needing a portable PA system.

The RMX 1850HD features a high-current toroidal transformer coupled with enhanced thermal performance and is designed to deliver higher continuous power to 2-ohm stereo or 4-ohm bridge mono loads. The amplifier includes low-frequency filters to boost system response, protect speakers, and ensure low-end tightness by accurately matching the amplifier's range to the loudspeakers. Each channel can be independently adjusted--50 Hz for most full-range systems, 30 Hz for subwoofers and large full-range systems, and full-range for studio monitoring. Independent user-defeatable clip limiters are included on the RMX 1850HD to reduce distortion without sacrificing performance.

Other features include: front-mounted gain controls for easy access; signal and clip LED indicators to monitor performance; balanced 1/4" (6.3 mm) TRS, XLR and barrier strip inputs; binding posts and Neutrik Speakon outputs; independent DC and thermal overload protection on each channel to automatically protect speakers and amplifier; and a continuously variable speed fan with back-to-front air flow to keep the amp and rack cool.

The new RMX 1850HD is 2-RU, 16" deep (19" rack mounting) and weighs 45 lb. (20.2 kg).
