This manual introduces the features and usage of RMX 4050HD and RMX 5050 power amplifiers.
This manual begins with safety warnings and symbols, explaining how to avoid electric shock, proper grounding, and environmental restrictions. It then describes the front‑panel controls, rack‑mount installation, and mode‑switch settings for stereo, parallel and bridge operation.
Detailed sections cover balanced and unbalanced input connections, output wiring, LED indicator functions, gain control, and full technical specifications. The final pages contain warranty information and contact details for QSC support.
| Output Power (8 Ω) | 800 W (RMX 4050HD) / 1050 W (RMX 5050) |
|---|---|
| Output Power (2 Ω) | 1600 W (RMX 4050HD) / 2000 W (RMX 5050) |
| Input Impedance | 20 kΩ balanced, 10 kΩ unbalanced |
| Input Sensitivity (rated power into 8 Ω) | 1.25 Vrms (RMX 4050HD) / 1.42 Vrms (RMX 5050) |
| Frequency Response | 20 Hz – 20 kHz |
Mount the unit with four screws and washers to the rack rail, keep the front and rear ventilation openings clear, and ensure the unit is level to avoid imbalance hazards.
Green indicates power on, red shows clipping or protection, yellow signals input level, and red flashing indicates over‑temperature or short‑circuit protection.
Do not use a load lower than 4 Ω when the amplifier is set to bridge mode.
