The Sennheiser SZI 1015-W is a wide-angle infrared (IR) emitter panel designed for distributing audio signals in professional hearing assistance systems across medium to large-sized venues. It converts audio from a compatible Sennheiser IR system base station (such as the SI 1015) into modulated infrared light, which is then broadcast uniformly throughout a room. Individuals using compatible IR receivers can pick up this light signal to receive clear, direct audio, making it an essential tool for providing assistive listening in compliance with accessibility standards like the ADA in theaters, courtrooms, lecture halls, and houses of worship. The "W" designation typically indicates a wide dispersion lens, engineered to provide even coverage over a broad area, reducing the number of panels needed for a given space.

This emitter panel is versatile, supporting single, dual, or multi-channel IR transmission. This means it can broadcast one program (e.g., the main audio feed), two different programs (e.g., the main mix and a translation), or multiple channels from a multi-channel system simultaneously, all on different subcarrier frequencies within the IR spectrum. The panel houses high-power infrared LEDs and is designed for efficient heat dissipation to ensure reliability during continuous operation. It features a low-profile, white housing intended for discrete ceiling or wall mounting, blending into the architecture of the venue. Connection to the system processor is typically via a proprietary multi-pin cable that carries both power and the audio signal.

As a B-Stock item, the SZI 1015-W has been professionally inspected and tested to guarantee full functionality. It may show minor cosmetic signs of prior use but offers the same performance and reliability as a new unit at a reduced cost. For system integrators and venue managers implementing or expanding an infrared assistive listening network, this emitter panel provides a professional-grade solution for delivering confidential, high-quality audio to hearing-impaired individuals, ensuring inclusive access to spoken content and enhancing the overall experience for all attendees.
