QSC GXD4 Professional Power Amplifier

For installed audio, security paging and surveillance monitoring where clarity and reliability matter most, the QSC GXD4 professional power amplifier provides consistent, professional-grade amplification from a compact footprint. The QSC GXD4 is engineered to deliver low-noise, low-distortion audio across a full bandwidth up to 20 kHz, preserving speech intelligibility for paging and the fidelity needed for background music and monitoring.
