Listen Technologies CMR3 calibrated measuring receiver - TCMR03

The Ampetronic CMR3 calibrated hearing loop measuring receiver for audio analysers is designed for measuring the performance of audio induction loop systems. The audio output is within ±0.25 dB over the frequency range and where used with a suitable audio analyser such as the Minilyser from Neutrik Ltd, the frequency response and field distribution of the magnetic field from any audio induction loop system can be plotted.
