Ampetronic ILR3 Loop Receiver w/ Stereo Headphones included.

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 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 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.

• Volume control
• 5 year warranty
• Auto power off with headphone removal
• > 100 hours life with 2 AA batteries


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.


Frequency response Standard: Flat 85Hz – 6kHz ± 0.5dB
Low Cut: 400Hz – 6kHz – 3dB (similar to hearing aid)
Output power >100mW into 16Ω load
Battery powered 2 x Alkaline AA (included)
Battery life >100 hours with Alkaline batteries
Indication ‘Good’ 0dB Green LED 400mA/m rms with sine
‘Okay’ -6dB Amber LED 400mA/m rms with sine


Dimensions width 62mm, depth 26mm, height 112mm
Temperature range IP20 : 20 to 90% relative humidity, -10 to 45ºC
