Overview

The Sennheiser SZI 1029-10 is a professional-grade infrared emitter panel engineered for assistive listening and audio distribution systems. Operating at 10 watts, it delivers strong infrared signal output capable of covering medium to large rooms, making it well suited for conference centers, courtrooms, theaters, lecture halls, and houses of worship. The panel supports single, dual, and multi-channel system configurations, allowing installers to tailor the setup to the specific needs of each venue, whether that involves a single language feed or simultaneous interpretation across multiple channels.

As part of Sennheiser's professional infrared product line, the SZI 1029-10 is designed for permanent installation and reliable day-in, day-out operation. Its flat panel design allows it to be mounted on walls or ceilings where it can provide unobstructed line-of-sight coverage to the listening area below. For larger or more complex spaces, multiple panels can be daisy-chained to extend coverage. This emitter is a system component rather than a standalone product, so it requires a compatible Sennheiser infrared modulator or transmitter to supply the audio signal for broadcast.
