QSC RMX850a is a 2 channel power amplifier – 2x 300w 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 200w @ 8Ω (EIA 1 kHz, 0.1% tdD)
2 x 300w @ 4Ω (EIA 1 kHz, 0.1% tdD)
2 x 430w @ 2Ω (EIA 1 kHz, 1% tdD)

600w @ 8Ω (EIA 1 kHz, 0.1% tdD)
