The Ampetronic ILR3+ is designed to perform the same induction receiver function as the ILR3 whilst also providing the added capability to check that the induction loop is functioning correctly.

When an induction loop is installed the venue manager or staff should always be supplied with at least one instrument that allows them to regularly monitor the system performance. The IR3+ performs this task without the added cost and complexity of a Field Strength Meter. It is simple and highly cost effective, and meets the requirements of the international loop performance Standard, IEC60118-4.

No technical skills are required to perform the basic checks, which allow an operator to listen to the system through headphones, and check that the sound level provided by the loop is sufficient.

The loop checking system comes with an easy to follow procedure for checking any loop system.
