Ampetronic ILR3+ Audio Induction Loop Tester Receiver

The Ampetronic ILR3+ performs the same induction receiver function as the ILR3 but has the added capability to check that the induction loop system is functioning correctly.

When an induction loop is installed it is good practice that the venue manager or staff should have at least one piece of equipment that allows them to regularly monitor the system performance. The IR3+ performs this task without the added cost and functionality of a Field Strength Meter. It is easy to use, 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 the user to listen to the system through headphones, and check that the sound level provided by the loop is sufficient.

The unit is powered by 2 off AA batteries, which are included, and is supplied with stereo headphones.

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

Using the ILR3+ to Check a Loop System

The ILR3+ is designed to make it easy for anyone to regularly check that their loop system is working, has a field strength of the correct level that provides a benefit, and meets the IEC60118-4 standard.

Field Strength Indicators

The ILR3+ has two indicators and these are calibrated to illuminate when the field strength is 400mA/m (0dB) or higher (GREEN) and between 200 and 400mA/m (-6 and 0dB) (YELLOW) as per the international standard,

Checking Loop System Status

The status of the loop can be checked by running continuous speech or music into the loop and monitoring the indicators when the ILR3+ is held in the appropriate location. There is a table on the back of the ILR3+ that shows what is or is not acceptable.

User Instructions

The ILR3+ comes with a simple user procedure to help guide anyone through the checking process. Using the ILR3+ requires no special knowledge of loop systems or any technical knowledge.

Who can use the ILR3+?

The ILR3+ is ideal for regular use by a facilities manager or non-technical member of staff. Regular checking will ensure that the loop system is working and providing a genuine benefit to the hard of hearing. The ILR3+ is an essential companion to any loop system installation.
