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
Designed for measuring the performance of audio frequency induction loop systems
Intended to be used as a calibrated probe with audio analysers
Including software based audio analysers running on portable or fixed computers
When used with a suitable signal source and analyser the magnetic field strength, background noise, frequency response and field distribution can be measured accurately
The CMR3 calibrated receiver 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.
Calibrated to provide 0dBu output for a field strength of 400mA/m RMS, in accordance with the international induction loop standard IEC60118-4 it is an essential tool for anyone wishing to assess loop system performance for analyses or certification.
