QSC CX404 — 4-Channel Professional Power Amplifier

This is a QSC CX404, part of QSC's PowerWave commercial amplifier series. Four channels of power in a compact 2-rack-space chassis, with PowerWave switching power supply technology for high output without excessive weight or heat. Stable into reactive or mismatched loads with load protection (on/off muting, DC-fault shutdown).

Per-channel attenuation controls, clip/signal LED metering per channel, and flexible configuration via rear-panel DIP switches — supports parallel inputs, bridge-mono, and stereo modes per channel pair. Balanced inputs (barrier strip + DB9 data port per channel pair), output via barrier-strip terminals. Made in USA.

A reliable workhorse amp commonly used in permanent installs, houses of worship, and commercial sound systems — QSC's build quality and PowerWave reliability make this a dependable choice for driving multiple zones or speaker runs.
