The ceiling-mounted speaker RC-306 from RCS Audio-Systems is a passive speaker designed for use in 100-V amplifier systems. It is manufactured in a full-metal design and intended for installation in suspended ceilings. The device features a discreet, round design with a frame height of approximately 1 mm, allowing it to blend seamlessly into most interior designs. The white color (RAL 9010) ensures good visual compatibility with standard ceiling colors.

Applications

The speaker is suitable for use in offices, administrative buildings, schools, hospitals, or retail stores where uniform, unobtrusive sound coverage is required. Due to the 100-V technology, it can be operated in larger installations with multiple speakers via a central amplifier. The 180° dispersion angle ensures broad, even sound distribution, providing clear speech reproduction and music playback.

Functions and Equipment in Detail

The RC-306 features a high-quality, wide-range speaker chassis with a diameter of 165 mm (6.5˝), ensuring clear and balanced sound reproduction. The rated power handling is 6 W (program power), with a maximum power handling of 15 W. The sound pressure levels are 97.5 dB at 1 W/1 m and 107 dB at maximum power (Pmax/1 m), providing sufficient loudness for indoor spaces. The frequency response ranges from 97 Hz to 20,000 Hz (±10 dB), enabling good reproduction of speech and music.

Technology Explained Simply

The speaker is equipped with a 100-V transformer that allows adaptation to different power levels (6/3/1.5 W). This is necessary to adjust the volume according to room size and the number of speakers. The impedance is 8 Ohm, which is standard for connecting to amplifier systems. Installation is tool-free: three bent snap springs automatically adapt to ceiling thickness and ensure secure mounting. The speaker insert is installed using a bayonet system, making installation quick and easy.

Compatibility and Accessories

The speaker is designed for use in 100-V amplifier systems. It is also available in a damp room version (FI-100), making it suitable for bathrooms, kitchens, or other damp areas. Installation requires a cutout with a diameter of 195 mm ± 5 mm and a minimum installation depth of 95 mm. The mounting plate and speaker ring are made of powder-coated steel, meeting the requirements of most fire safety regulations.

Installation and Mounting

Installation is tool-free in suspended ceilings. The three mounting clips automatically adapt to ceiling thickness and ensure secure fastening. The speaker insert is installed using a bayonet system, minimizing installation time. The external dimensions are 220 mm in diameter, with a maximum installation depth of 95 mm. The mounting is suitable for all common ceiling thicknesses.

Operational Advantages

The RC-306 offers quick, tool-free installation, even sound distribution due to the 180° dispersion angle, and a robust full-metal construction. The use of powder-coated steel for the mounting plate and speaker ring ensures high mechanical stability and complies with most fire safety requirements. The 100-V technology enables flexible power adjustment and centralized control of the sound system.
