The QSC RMX 4050HD is a professional, moderately priced stereo power amplifier housed in a sturdy 3 RU rackmountable chassis, offering 800 Watts of output power at 8 Ohms, and over 4000 Watts at 4 Ohms bridged. This model is uniquely equipped with an improved thermal protection design that allows for higher continuous power, and therefore better output performance, at 2-Ohm stereo and 4-Ohm bridged applications.
The RMX 4050HD also offers independent and defeatable clip limiters, and efficient power reserves created by a high current toroidal transformer, resulting in improved and consistent high level transient response. The XLR , 1/4" TRS, and barrier strip connectors cover the standard input requirements, and the selectable 30 Hz and 50 Hz low frequency filters offer additional speaker protection and increased headroom. The outputs are on either barrier strips or the ever popular Speakon connectors.
The RMX 4050HD is packed with design features that contribute toward an excellent value for the budget-conscious but picky professional, and QSC is comfortable recommending the RMX series for studio monitoring or live sound system applications.
- Rackmountable power amplifier with unique, advanced thermal protection; higher continuous power output at 2 Ohms Stereo and 4 Ohms Bridge-Mono applications
- High-current toroidal transformer and filter capacitance for ensured energy reserves, improved high level transient response across variety of speaker loads
- Output device direct-mounted to heat sink for optimum thermal coupling, cooling
- 4000 Watts maximum power output bridged mono
- Independent defeatable clip limiters reduce distortion without affecting peak performance, response
- Selectable low-frequency filters boost system response, protect speakers; match amplifier's range to speakers for tighter LF response
- Low-noise variable speed fans with rear-to-front air flow, keep amplifiers and racks cooler
- Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
