A built-in tilt to the high-frequency horns on 3- and 4-way systems provides more even convergence with the mid-range pattern, ensuring optimum seating-area coverage.

The Digital Cinema Series (DCS) includes 2-way, 3-way, and 4-way screen channel loudspeakers. It’s a diverse collection, but every model embodies QSC attention to detail in design and construction. The result is the smartest loudspeaker line in cinema, starting with a host of innovations built into our screen channel lines.
