The QSC CX204V is a versatile four-channel power amplifier from the respected CX Series, engineered to deliver reliable, high-fidelity amplification for a variety of professional audio applications. This compact, yet powerful, amplifier is particularly well-suited for distributed audio systems, multi-zone installations, and driving multiple monitor wedges or fill speakers where independent channel control is advantageous. Utilizing a Class AB output stage paired with a robust toroidal transformer and linear power supply, the CX204V provides clean, transparent power with low distortion, ensuring accurate sound reproduction for both music and speech. Its four independent channels offer flexible configuration options, allowing each channel to drive a different load or zone, which simplifies system design and reduces the total number of amplifiers required in a rack.

Each channel is equipped with comprehensive controls and protection features. Individual level controls and signal-present LEDs allow for precise gain staging and quick visual confirmation of input activity. The amplifier incorporates QSC's advanced protection circuitry, safeguarding against conditions such as thermal overload, short circuits, DC offset, and radio frequency interference. For installations requiring constant voltage distribution, the CX204V includes a mode switch per channel to select between low-impedance (4/8 ohm) and 70V/100V high-impedance operation, making it a truly flexible solution for commercial sound systems. Output connectivity is provided via secure binding posts that accept bare wire, spade lugs, or banana plugs, while input connections are made via balanced XLR and 1/4-inch TRS jacks.

Housed in a lightweight 2U rack-mount chassis with a steel enclosure, the CX204V is designed for efficient cooling and durability in both portable and fixed installation contexts. Its straightforward design emphasizes operational reliability and ease of use over complex digital networking, making it an ideal workhorse for system integrators and rental companies. By combining multi-channel flexibility, proven analog performance, and essential protection features in a single unit, the QSC CX204V provides a cost-effective and space-efficient power solution for a wide range of sound reinforcement challenges.
