Wireless Microphone Systems
We do our best to keep healthy stocks across the many Wireless Microphone System SKUs but in the rare case where we don't have your required system in stock, please contact our sales team as we can often make your product to order by borrowing the system components (transmitters, receivers or mics) from other stocked systems.

Main Features
Cost effective and simple solution for measuring, setting up and commissioning an induction loop system
Ergonomically designed hand held instrument for measuring loop system performance
Three calibrated operational modes for the assessment of Background Noise, Field Strength and Frequency Response
Doubles as a loop listener, with a headphone output to listen to the signal in the loop
The FSM Magnetic Field Strength Meter from Ampetronic is a cost effective and simple solution for measuring, setting up and commissioning an induction loop system to the requirements of IEC60118-4. The meter is an ergonomically designed hand held instrument for measuring loop system performance. There are three calibrated operational modes for the assessment of Background Noise, Field Strength and Frequency Response as required to ensure correct function of the loop system.
