QSC RMX5050a is a 2 channel power amplifier - 2x 1800w at 4 ohms.

The RMXa series of power amplifiers by QSC offers a fair bit of clout, without a hefty price tag. There’s a trade-off? To be fair, RMXa amplifers are not the lightest thing going around - but for a fixed installation, this is surely not a deal-breaker.

Inputs via XLR and 1/4-inch balanced inputs (or barrier-strip, if you’re more the ‘screw-in’ kind of operator), with outputs being Speakon® and binding post. Also on the rear is your “Mode Switches” section, being controls for Clip Limiting, Low Frequency Filters, and Stereo / Parallel / Bridge Modes.

Front panel controls are Ch1 and Ch2 gain knobs, along with clip / signal LED indicators.

Power in Stereo Mode:
2 x 1100w @ 8Ω (EIA 1 kHz, 0.1% tdD)
2 x 1800w @ 4Ω (EIA 1 kHz, 0.1% tdD)
2 x 2500w @ 2Ω (EIA 1 kHz, 1% tdD)

Power in Bridge-Mono Mode:
3600w @ 8Ω (EIA 1 kHz, 0.1% tdD)
5000w @4Ω (EIA 1 kHz, 1% tdD)

Height: 3 RU
Weight: 33.1 kg

RMX5050a features:

  • High-current toroidal transformers, for greater 2-ohm power and low noise
  • Independent user-defeatable clip limiters reduce distortion
  • Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
  • The 4000-watt RMX4050a operates on a standard 15 amp plug
  • Both the RMX4050a and the RMX5050a feature a dual mono, high-current power supply for increased reliability and performance
  • The RMX4050a's particularly exceptional combination of cooling capacity and electrical efficiency provides robust thermal performance suitable for high continuous power in 2-ohm stereo or 4-ohm bridged applications.
  • Balanced 1/4-inch (6.3 mm) TRS, XLR, and barrier strip inputs
  • Touch-proof binding post and Neutrik Speakon® outputs
  • Front mounted gain controls for easy access
  • Signal and clip LED indicators for monitoring performance
  • Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
