The Sennheiser SZI 1029-10-US-B is a 10-watt infrared (IR) emitter panel designed for professional assisted listening systems in the United States, such as those used in theaters, houses of worship, courtrooms, and museums. This emitter broadcasts audio signals via infrared light to wireless headsets worn by listeners, providing clear, private sound without radio frequency interference or spillage outside the designated area. The panel is capable of supporting single, dual, or multi-channel audio transmission, allowing venues to offer multiple audio streams, such as different languages or audio descriptions, simultaneously. Its 10-watt output power ensures strong, uniform coverage across large or complex spaces, and the broad-angle design of the emitter diodes helps to fill the room with a consistent IR signal, minimizing dead spots.

Constructed for permanent installation, the SZI 1029-10 is a flat, low-profile panel that can be discreetly mounted on walls or ceilings. It is designed to connect to an IR system modulator, which feeds the audio signals to the emitter after they have been encoded onto a carrier frequency. The panel operates on a standard AC power supply and includes status indicators for power and signal presence. As a B-Stock item, this emitter offers the full performance and reliability of a new unit at a reduced cost, though it may have minor cosmetic imperfections or be a factory-refurbished product. It is a critical component in creating an accessible listening environment, ensuring compliance with regulations like the Americans with Disabilities Act (ADA) by providing high-quality audio assistance to individuals with hearing impairments.

The emitter panel is part of Sennheiser's comprehensive infrared technology ecosystem, known for its high audio fidelity and reliability. By using infrared light, the system guarantees secure transmission that is contained within the treated room, as IR signals cannot penetrate walls. This makes it ideal for confidential proceedings or venues where multiple events occur in adjacent rooms. For system integrators and venue managers, the SZI 1029-10-US-B represents a professional-grade solution for delivering inclusive audio experiences to diverse audiences.
