The Q-SYS SC-413C is a professional-grade 3-way screen channel loudspeaker system designed to meet the demanding requirements of modern cinema sound reproduction. As part of the Digital Cinema Speaker Series (DCS), it offers selectable bi-amp or tri-amp configurations, providing flexibility for various amplification setups. The system comprises two main components: the MH-1075C mid-high frequency system and the LF-4115 low-frequency system, both engineered for optimal performance and ease of installation.

The Key Features of the Q-SYS SC-413C:

• Three-Way Selectable Amplification: Choose between bi-amp or tri-amp configurations to suit specific audio system requirements.
• Optimized Coverage: The MH-1075C mid-high system provides 90° horizontal by +20° to -30° vertical coverage, ensuring consistent sound distribution across the audience area.
• Robust Construction: The LF-4115 low-frequency enclosure is constructed from medium-density fiberboard (MDF) and is heavily braced to minimize unwanted resonances, delivering clear and accurate bass reproduction.
• Low-Distortion Waveguides: Engineered waveguides reduce distortion, resulting in highly articulate dialogue and improved overall sound clarity.
• Compact Design: With a shallow depth of 20 inches, the SC-413C facilitates installation in various theater configurations without compromising performance.
• THX Approved: Meets stringent THX standards for audio performance, ensuring a high-quality cinematic experience.
