Infrared Systems

Sennheiser infrared systems are ideal for wireless, interference-free secure assistive listening and interpretation for theaters, houses of worship, courtrooms, conferences and much more! With their unique amplitude and frequency modulation process, Sennheiser infrared systems offer high-quality, dependable audio with single, dual, stereo and multiple channel operation. Sennheiser IR systems can be modeled in EASE design software. Infrared products available to IS dealers. Please contact your Sennheiser representative for more information. The main components of an IR System: the Modulator, Emitter and Receiver

SZI30 SZI1015 SZI1029 Emitter - Radio Frequency to Infrared Light This device and its wall or ceiling mounting hardware are placed in the room where assistive listening is needed. The signal from the Modulator is converted to invisible light by the emitter's LEDs. This transmits the program to the Receiver.

RI150 HDI830 EKI1029

SI30 SZI1015T SP230

Receiver - Infrared Light to Audio Frequency The receiver section is comprised of a stethophone (headset worn under the chin), its rechargeable battery and the battery charger. Here the light from the emitters is converted back to sound for the listener.

Transmitter - Audio Frequency to Infrared Light For smaller rooms or portable applications, Sennheiser offers transmitters that combine a modulator and emitter into one device. Here audio frequencies are converted to infrared light directly. Some transmitters facilitate simple set-ups for small boardrooms. Other transmitters include features that make temporary installations simpler.

Planning Sennheiser makes IR systems for many applications from single-channel systems for assistive listening to large-scale, multi-language translation systems - up to 32 channels simultaneously. Care must be taken to consider the room's dimensions and layout (including balconies and side rooms).

Coverage Consider an infrared emitter as you would a light source. Panels must be selected in the appropriate size and quantity for the square footage of the room in which the system will be used. Sennheiser emitter panels all contain the ability to daisy chain multiple panels together to cover wide- or odd-shaped rooms. Our emitter panels also feature automatic gain control so that there is no loss of signal in a multi-panel array or configuration.

PlacementSennheiser offers the ability to mount emitters on a variety of ceiling or wall mounts. Smaller emitters such as the SZI30 can even be assembled in an array to create a longer throw or wider spread of the IR beam. When selecting an appropriate position for your emitters, keep in mind that they should be placed in a manner to provide even illumination throughout the room. They should be mounted high (generally 10-14 ft.) pointing down towards those wearing receivers. If emitters are placed on both sides of an altar they should be aimed diagonally across the room. Except in rare occasions, any number of panels can be placed in a room without concern of interference between panels. For assistance or more information on infrared transmission systems, please contact your Sennheiser sales representative or visit www.sennheiserusa.com/infoport.

SI1015 SI29-5 Modulator - Audio Frequency to Radio Frequency This part of the system is comprised of a rack-mounted device that will receive audio signals from the Public Address or sound system. Audio signals are superimposed onto a carrier frequency and travel by coaxial cable to the Emitter.
