Ampetronic ILR3+ audio induction loop receiver with field strength indicators

General Description

The Ampetronic ILR3+ is a high quality audio induction loop receiver which allows the user to listen to an audio frequency induction loop system using a standard pair of stereo headphones (supplied). It has a vertically mounted pick up coil and a low cut filter function to emulate the performance of a hearing aid switched to the T position.

It is an essential tool for anyone installing maintaining or managing facilities fitted with induction loops providing them with immediate confirmation that the loop is running. Two extra LEDs (marked HI and LO) on the top of the unit provide a visual guide to the strength of the field created by the loop system. In addition, it can be used by anyone without a hearing aid who needs a little extra assistance to hear
