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.
