QSC RMX 4050A Stereo Power Amplifier

State-of-the-art amplification. 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.
