ILR3 Audio loop receiver

ILR3 Induction Loop Receiver

Part code: TILR03

The 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 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.

ILR3 Audio loop receiver

The ILR3+ also has LED indications to show field strength, for more accurate monitoring of a loop system. (To measure the performance of an induction loop system, Ampetronic's calibrated receiver CMR3 must be used). In addition, the ILR3 or ILR3+ can be used by anyone without a hearing aid who needs a little extra assistance to hear.

Applications include

Checking that an induction loop system is working. Essential for installers, venue managers and event organisers
Recording the output of a loop system
Providing assistance to people without a hearing aid
Locating sources of interference
Checking loop coverage and signal overspill

Low distortion
Flat frequency response to 6kHz
Low cut filter—to simulate hearing aid response
Low and high field strength indicators according to IEC60118-4 (ILR3+)

Low Cut Filter

The ILR3 incorporates a low cut filter. Switching the low cut filter on attenuates the low frequency (bass) components of the signal emulating a typical hearing aid response and helps reduce the annoying ‘buzz’ caused by some AC power circuits.

For best reception in general use and where there is no low frequency interference, the ILR3 should be used with the ‘flat’ frequency
response selected.
