The SC-106 is a ceiling-mounted speaker from RCS Audio-Systems, specifically designed for professional sound systems. It is suitable for background sound, voice reproduction, and use in ELA systems (Electronic Speaker Systems) with 100-V technology. The device features a discreet, square design with a frame height of approximately 2 mm, allowing it to blend seamlessly into most ceilings. Installation is carried out using a quick-tension locking system, where after removing the perforated plate (e.g., with a screwdriver), four screws are tightened. This method enables a tool-free, secure, and time-saving installation. The construction is theft-secure, with the mounting frame made of high-quality plastic and the perforated plate made of coated steel.

Applications

The SC-106 is suitable for use in offices, waiting areas, shopping centres, schools, and other indoor spaces where discreet, uniform sound coverage is required. The 100-V technology allows flexible control over long cable runs, making it particularly suitable for larger rooms or multiple rooms within a building. The integrated power taps (6 W, 3 W, 1.5 W) allow adjustable volume levels depending on room size and acoustic requirements.

Functions and Equipment in Detail

The speaker features a 5¼˝ wide-range chassis with an integrated tweeter, ensuring clear and balanced sound reproduction. The frequency response range is 75 Hz to 20,000 Hz (±10 dB), enabling good reproduction of speech and music. The maximum sound pressure level (SPL Pmax) is 100 dB at 3 kHz, sufficient for adequate volume in medium-sized rooms. The rated power (program power) is 6 W, with a maximum power handling of 15 W.

Technology Explained Simply

The integrated 100-V transformer enables control via a 100-V line, commonly used in professional sound systems. The three power taps (6/3/1.5 W) allow flexible volume adjustment according to room size. The impedance is 8 Ohm, ensuring standard compatibility with amplifiers and cabling. The sound pressure level at 1 W/1 m is 91.5 dB, indicating efficient speaker performance. The dispersion angles are 180° at 1 kHz, 120° at 4 kHz, and 70° at 8 kHz, providing broad yet controlled sound radiation.

Compatibility and Accessories

The SC-106 is compatible with the mounting frame EZ-110, suitable for installation in ceilings or walls made of brick, concrete, or similar materials. The frame, made of impregnated particleboard, has external dimensions of 193 mm (H) × 193 mm (W) × 84 mm (D), enabling secure mounting in heavy substrates. Installation requires a square cutout with a side length of 145 mm in the ceiling material.

Installation and Mounting

Installation involves removing the perforated plate, tightening the four screws, and then inserting the speaker into the designated cutout. The installation depth is 60 mm, and the side length of the housing is 178 mm. The tool-free mounting reduces installation time and increases safety. The theft-secure construction prevents unauthorized removal of the speaker.

Operational Advantages

The SC-106 provides reliable, quiet, and uniform sound coverage with good speech intelligibility. The discreet appearance ensures unobtrusive integration into room design. The 100-V technology enables flexible, scalable system design. The robust construction and tool-free mounting simplify installation and maintenance. The device is designed for indoor use and meets the requirements of professional sound systems.
