QSC RMX4050HD Amplifier Test Results
Good heavyweight all-rounder from QSC
The RMX4050HD performed well in the tests, the results were consistent and distortion was low. Clipping behaviour is excellent with no nasties, and at 40Hz there is no evidence of power supply ripple on either channel. A very good all-round heavyweight amplifier.

All results taken with sine wave input into a resistive dummy load of 8, 4 and 2 ohms (where applicable), two channels simultaneously driven (unless otherwise stated), at the threshold of clipping. These results should be considered maximum 'continuous RMS' power ratings (>5 seconds). Distortion measurements, labelled THD%, are taken with an HP8903A audio analyser (80kHz Bandwidth). | |||||||||||||||||||||||||||||||||||

1 Power to weight ratio is calculated by taking the average of the power measurements at 4 ohms, multiplying by the number of driven amp channels, and then dividing this value by the weight of the amplifier.
