The Lavalier lapel microphone from RCS Audio-Systems, model LA-300, is a compact, black-lacquered microphone designed for use in event technology. It serves as a small, discreet recording unit that is directly attached to clothing to capture speech signals during presentations, lectures, or interviews. The device features a 3.5 mm jack plug intended for connection to compatible audio or transmission systems. The black-lacquered surface ensures unobtrusive integration into formal or professional attire.

Lavalier microphone
A lavalier microphone is a small, typically clothing-mounted microphone suitable for direct and spatially independent speech recording. The LA-300 model is specifically designed for use with the UBT-016 transmitter, enabling wireless transmission of audio signals. The combination of compact design and integrated jack connector makes it a flexible tool for mobile applications where fixed cabling is impractical.

Connection and interface technology
The microphone features a standardized 3.5 mm jack plug, widely used in event technology and professional audio. This plug ensures a secure mechanical connection and reliable electrical signal transmission. The connection is made directly to the UBT-016 transmitter, enabling the microphone to function as an input device for wireless transmission. The use of a jack plug ensures simple and robust installation without requiring additional adapters or converters.

Compatibility and accessories
The lavalier microphone LA-300 is specifically developed for use with the UBT-016 transmitter. The combination of both devices enables wireless transmission of speech signals, with the microphone serving as the signal source. It is not intended for use with other transmitters or systems unless they support the same connection standard (3.5 mm jack) and required signal transmission.

Application areas
The microphone is suitable for applications requiring discreet and mobile speech recording, such as lectures, conferences, presentations, interviews, or small live events. Due to its small size and inconspicuous color, it is particularly suitable for speakers who need to move freely without the microphone being noticeable. Use with the UBT-016 transmitter extends its application in wireless systems.

Functions and equipment in detail
The microphone features an integrated jack plug that connects directly to the UBT-016 transmitter. It does not include additional functions such as an internal amplifier, battery, or switch. Signal transmission occurs passively via the jack connector, with power supply and signal processing handled by the transmitter. The black-lacquered surface is robust and resistant to minor mechanical stress.

Mounting and installation
Mounting is done by attaching the microphone to clothing, ideally near the mouth, to ensure clear speech capture. The jack plug is inserted directly into the corresponding input of the UBT-016 transmitter. No additional tools or adapters are required. The connection is mechanically stable and allows for quick installation and removal.

Advantages in operation
The lavalier microphone LA-300 offers a compact and discreet solution for mobile speech recording. Use with the UBT-016 transmitter enables wireless transmission, ensuring the speaker’s freedom of movement is not restricted. Simple mounting and a robust jack connector ensure reliable and quick setup. The black-lacquered surface blends inconspicuously into formal or professional environments.

Technology explained simply
A lavalier microphone like the LA-300 captures sound waves in close proximity to the source—in this case, the speaker’s voice. The microphone converts these sound waves into electrical signals, which are transmitted via the 3.5 mm jack plug to the UBT-016 transmitter. The transmitter processes the signal and transmits it wirelessly to the receiver. The technology is passive, meaning the microphone requires no internal power supply, as it is powered by the transmitter. The black-lacquered surface is designed for inconspicuous attachment to clothing.

Color and design
The microphone is black-lacquered, making it suitable for use in formal or professional environments. The color is not only aesthetic but also functional, as it makes the microphone less visible when mounted on dark clothing. The design is minimalist and reduced to essential functions, without unnecessary elements.
