High Efficiency Neck Loop Microphone & Wired PTT/Tone

This Neck Loop provides one the best solutions for covert operations when used in conjunction with Wireless Induction Earpiece for radio receive audio. It is arguably the smallest designs on the market but still retains the capability to generate high strength magnetic audio field.


It has a built in high quality - Knowles microphone for covert transmissions along with a wired two button PTT/ TONE assembly. The buttons are recessed in an ergonomically designed slim moulding that is very pleasing to the touch. The tone button sends out real time tones over the air and are heard in the user’s induction earpiece for confidence.


The Neck Loop is usually worn under clothing and the audio signal from the speaker output of radio terminal is fed into the Loop. The current flowing in the Loop varies with the audio signal & this in turn produces a magnetic field within the vicinity of the user’s head area.  
The receive audio is heard with the use of  Analogue or Digital Wireless Earpiece, the earpiece contains a coil which converts the magnetic field back to audio & feeds it to a miniature sound amplifier.


It is recommended the user only ever uses Sonic recommended Wireless Earpieces in conjunction with Neck Loop, this will ensure maximum benefit while retaining the sensitivity and clarity of audio in the field of operation.


All cables used in the design meet a very high standard of cable flex operations and pull tests. The loop wire is made of 3mm Silicon Rubber and makes it Anti Tangle/ resistant to forming kinks.


Depending on the radio, the factory will automatically set the microphone gain sensitivity to suit the radio. The microphone is factory configured to be sensitive enough to pick up the users voice but not overly sensitive to allow ambient background noises to drown desired spoken voice from user.


This product is available in all black (including cables) or European skin colour.
