The RC-110 from RCS Audio-Systems is a ceiling-mounted speaker with a rated power of 10 W (program power) and a maximum music power of 15 W. It is designed for use in 100-V amplifier systems and features tap settings of 10/5/2.5 W, enabling flexible integration into existing installations. The device is available in white colour and features a modern, discreet design that blends seamlessly into ceilings. The frame height is approximately 2 mm, ensuring a flush installation.

Applications
This speaker is suitable for a wide range of indoor applications, particularly for background music systems, paging systems, and voice alarm systems. It is designed for public spaces such as offices, administrative buildings, hotels, schools, shopping centres, as well as for corridors, lobbies, and waiting areas. Its robust construction also makes it suitable for areas with increased security requirements. A special moisture-resistant version (option FI-100) is available, equipped with an extra-treated chassis and a matching transformer, allowing use in damp environments such as bathrooms or kitchens.

Functions and Equipment in Detail
The RC-110 features a quick-release locking system, significantly simplifying installation and removal. Installation is performed by tightening four screws, which become accessible after lifting the mounting plate (e.g., using a screwdriver). The mounting frame is made of high-quality plastic, and the mounting plate is made of coated steel. The construction is theft-secure, making it particularly suitable for public and commercial spaces. The device is equipped with a broadband 5¼-inch chassis featuring an integrated tweeter cone to ensure clear voice reproduction and clean music playback.

Technology Explained Simply
The speaker has an impedance of 8 ohms, representing a standard matching for many amplifiers and distribution networks. The rated power handling is 10 W (program power), with a maximum music power of 15 W. The sound pressure level at 1 W/1 m is 91.5 dB, indicating good efficiency. At maximum power (Pmax), the speaker reaches 102 dB at 3 kHz, ensuring clear and sufficiently loud reproduction in medium-sized rooms. The frequency range spans from 75 Hz to 20,000 Hz (±10 dB), enabling comprehensive sound reproduction from deep bass to high treble frequencies. The radiation angles are 180° at 1 kHz, 110° at 4 kHz, and 60° at 8 kHz, ensuring broad yet targeted sound distribution. The installation depth is a maximum of 66 mm, and the outer diameter of the device is 200 mm. The speaker diameter is 130 mm.

Compatibility and Accessories
The RC-110 is designed for use in 100-V systems, commonly used in many professional sound installations. The tap settings of 10/5/2.5 W allow flexible integration into existing distribution networks. As an accessory, the installation socket EPIC POWER M12 G4 M16 3+PE M 0.2m (1) is available, enabling safe and orderly cabling. The moisture-resistant version (FI-100) is available as an option and provides enhanced protection for damp environments.

Installation and Mounting
Installation is performed by tightening four screws, which become accessible after lifting the mounting plate. The mounting frame adapts to various ceiling thicknesses and is also suitable for plasterboard ceilings. The required cutout in the ceiling material should have a diameter of 170 mm ± 5 mm. The construction ensures secure and stable mounting.

Operational Advantages
The RC-110 offers high speech intelligibility and wide sound dispersion, making it particularly suitable for information and alarm functions. The theft-secure construction and discreet design ensure unobtrusive integration into various indoor environments. The quick-release mounting significantly reduces installation time. The optional moisture-resistant version extends the application range to damp environments. The 100-V technology enables flexible and scalable system planning.
