OP-LR/M

Description

Opus Loop Receiver Measurer is the most compact loop listening device on the market.

It allows anybody to listen to an audio frequency induction loop system just like they were wearing an hearing device switched to the « T » position.

In order to make sure your loop system is functional and respecting the IEC 60118-4 norm it is essential to use a control device. The OP-LRM is an easy-to-use and straight forward solution to do so.

Just by turning it on, you’ll be able to control the quality of the signal received as well as making sure it respect the international norm, thanks to its easy to read, led indicators.
