The ILR3+ is a high-quality audio induction loop receiver that 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, therefore, an essential tool for anyone installing, maintaining, or managing facilities fitted with induction loops, providing them with immediate confirmation that the loop is running. The ILR3+ also has LED indications to show field strength for accurate monitoring of a loop system, which provides the added capability to check that the induction loop is functioning correctly.
