Audio Loop explained

The loop is simply a wire placed around an area, but not necessarily around a perimeter. The wire is usually laid flush with floors and walls and may even be placed in the baseboards or underneath the carpet. The audio output from the sound board is routed through the loop amplifier.

Places of use


Audio/Induction loop in conjunction with SLS systems
Under shop counters
Conference halls
Public spaces
Medical facilities


Reduces the necessary cross section of copper because of optimal shape in comparison to round wires
Ease of getting admittance for a winding construction due to the optimal safety
More reliable due to reduction of vibration, better thermal conductivity
Prevents danger of short circuit between primary and secondary windings
