SENNSIS P-320W portable infrared simultaneous interpretation system       SENNSIS portable infrared translation system

Each system comprises a microphone, infrared radiator stack and a preamplifier. The preamplifier has all the connections that are ever likely to be needed and an (optional) integrated radio microphone receiver.

The main input into the system is a lightweight headband “whisper” microphone that plugs directly into the preamplifier, or an optional radio belt pack transmitter, allowing the interpreter the freedom to move. No longer does the interpreter need to sit conspicuously at the front of the room! A radio handheld microphone and digital radio system is also available. All microphones have a mute “cough” switch.

The interpreter’s voice is then transmitted by the radiators around the room in the form of infrared (invisible) light. As this light cannot penetrate walls this provides complete confidentiality*.

Headset receivers are used by the delegates to convert the infrared signal to audio. All Sennsis infrared systems are compatible with the new Sennheiser HDI 830 receiver (above) and the older Sennheiser RI 150 receiver (as used by many organisations and councils). A neck loop receiver for use by hearing aid wearers is also available.
