The Sennheiser SI 1015 is a professional two-channel infrared remote control transmitter designed to wirelessly operate compatible Sennheiser equipment, such as microphone mute switches or volume controls, within a conference room or installed sound environment. This unit utilizes infrared (IR) light to transmit control signals, offering a secure, license-free, and interference-free method of communication that is contained within the room as IR cannot penetrate walls. It is typically used in boardrooms, courtrooms, and council chambers to provide moderators or presenters with discreet, wireless control over microphone functions without being tethered to a central control panel. The transmitter is designed with an ergonomic, handheld form factor, featuring clearly labeled buttons for intuitive operation of its two independent channels.

The SI 1015 transmits digital command codes via a broad-beam infrared LED, ensuring reliable reception by the IR sensor on the target equipment from various angles within the room. It is powered by standard batteries, making it completely portable and easy to pass between participants. The system simplifies the management of discussions by allowing a chairman or speaker to quickly mute or unmute specific microphone channels, request to speak, or control other pre-programmed functions from their seat. This enhances the flow of formal meetings and supports structured debate by giving control back to the individuals at the table without requiring them to move or call for technical assistance.

For AV system integrators, the Sennheiser SI 1015 adds a layer of flexibility and user-friendliness to installed sound systems. It seamlessly integrates with Sennheiser's conference and discussion systems, providing a reliable wireless link for control functions that are critical to the smooth operation of professional meetings. By enabling wireless remote control, it reduces cable clutter and increases the perceived sophistication and ease of use of the installed technology, contributing to a more efficient and controlled meeting environment where participants can focus on the discussion rather than the equipment.
