The SC-110 C from RCS Audio-Systems is an in-ceiling speaker for professional sound systems, specifically designed for mounting in ceilings or walls. It features a 2-way coaxial speaker chassis, ensuring clear and detailed sound reproduction. The construction is designed for secure and tool-free installation, with a quick-tension locking mechanism that speeds up the installation process. Installation is performed by tightening four screws, which become accessible after removing the perforated metal plate. The theft-secure design makes the speaker particularly suitable for public or commercial spaces.

Applications

The SC-110 C is intended for sound applications in conference rooms, foyers, retail areas, or similar indoor spaces. The 100-V technology enables flexible integration into existing or new distribution networks. The power handling capacity of up to 40 W program power ensures sufficient volume and sound quality even in larger rooms.

Functions and Equipment in Detail

The 2-way coaxial chassis integrates a separate tweeter into the woofer cone, resulting in a very linear frequency response. This improves speech intelligibility and enables detailed music reproduction. The maximum sound pressure level (SPL) is 104 dB at 6 kHz, indicating high sound output capability. The frequency response range of 45 Hz to 20,000 Hz covers the entire audible spectrum. The three power taps (10 W, 5 W, 2.5 W) allow adjustable volume control depending on room size and requirements.

Technology Explained Simply

The 100-V technology is a standard solution in professional sound systems, where speakers are powered via a high-voltage network. This allows for long cable runs without significant signal loss. The impedance is 8 Ohm, representing a standard match for amplifiers and distributors. The sound pressure sensitivity of 92 dB at 1 W/1 m indicates the speaker's efficiency. The radiation angles of 180°, 80°, and 110° at 1, 4, and 8 kHz describe the directivity characteristics, ensuring even sound distribution in the room.

Compatibility and Accessories

The speaker is compatible with an installation frame for wall and ceiling-mounted speakers of the SC-110/120 C series. This frame supports installation and ensures a clean visual integration into the ceiling.

Installation and Mounting

Mounting is performed by tightening four screws, which become accessible after removing the perforated metal plate. The quick-tension locking mechanism enables tool-free and time-saving installation. The installation depth is 70 mm, and the side length is 220 mm. The discreet design with a frame height of approximately 2 mm ensures an unobtrusive installation appearance.

Operational Advantages

The SC-110 C offers high sound quality through the coaxial chassis, secure mounting through the theft-secure construction, and flexible power adjustment via the three taps. The 100-V technology enables a scalable sound solution that can be adapted to different room sizes. The white color and discreet design blend unobtrusively into most indoor environments.
