SC-1120 Small Room Screen Channel Overview

The DCS SC-1120 is a compact two-way passive screen channel loudspeaker optimized for smaller cinemas up to 35 feet (11 m) in room length. Featuring a 12-inch low-frequency driver and high-frequency compression driver mounted to a 90° axisymmetric horn, the SC-1120 delivers controlled coverage and strong vocal intelligibility in space-constrained installations.

Engineered for Compact Cinema Installations

With a frequency range of 48 Hz to 19 kHz and peak output up to 126 dB SPL, the SC-1120 provides reliable front-channel performance while requiring less than 12 inches behind the screen. Its passive crossover design allows operation from a single amplifier channel, simplifying system integration for smaller auditoriums.

Applications

  • Small-format cinema auditoriums
  • Rooms up to 35 ft (11 m) in length
  • Compact screen channel installations
  • Space-constrained retrofit projects
