General Description

Portable infrared hearing systems are a cost effective and easy to use alternative to perimeter induction loop systems. They have the advantage of no trailing wires around the area to be covered and can be set up in minutes. They are ideal for meetings of a confidential nature as the infrared light cannot penetrate the walls of the room.

The Sennsis PIR 400 is supplied in a heavy-duty Peli-style transport case with integrated retractable handle and wheels to enable the system to be towed like a suitcase. The case can store the Sennsis PIR 400 (on the telescopic table stand), power supply unit, boundary microphone, one Sennheiser L 300-10-10 ten-way receiver charger and up to ten Sennheiser infrared receivers.
