QSC DCA3422 – 2-Channel 800W Digital Cinema Amplifier

Product Overview

The QSC DCA3422 is a two-channel digital cinema amplifier and the high-power model in QSC's DataPort cinema amplifier family, built to drive the most demanding cinema screen channels and subwoofers. It delivers 800 watts per channel at 8 ohms, 1,250 watts at 4 ohms, and 1,700 watts at 2 ohms from a compact 2U chassis. The DCA3422 connects to QSC DCP cinema processors, DCM monitors, or a Q-SYS Core via the CODP4 DataPort output card.

Product Description

With QSC's PowerLight switch-mode power supply, the DCA3422 provides the high continuous and peak power needed for large-format screen and subwoofer channels while maintaining a hum-free noise floor and low distortion. The chassis is only 3.5 inches (2U) high and 14 inches deep, weighs about 21 pounds, and fits standard-depth racks — even the most powerful cinema systems can be built in a single rack. Patented Output Averaging short-circuit protection, Active Inrush Limiting, and variable-speed fan cooling keep it reliable in enclosed projection booths, and Neutrik Speakon plus barrier-strip outputs ensure secure connections. For lower power requirements, compare the QSC DCA3022, and for Q-SYS integration add the CODP4 DataPort output card.

Frequently Asked Questions

Is the DCA3422 a networked Q-SYS amplifier? No. It is a DataPort/analog amplifier; to use it in a Q-SYS theatre, drive it from a Q-SYS Core through the CODP4 DataPort output card.

What processors and sources are compatible? QSC DCP cinema processors, DCM monitors, Q-SYS Cores via CODP4, and standard analog line-level sources.

Can the most powerful cinema systems fit in one rack? Yes — the DCA3422 is only 2U high and 14 inches deep, so high-power systems can be built compactly in standard racks.
