3.1 Installation of the induction loop
To use the LOS amplifier, the induction loop must be installed in a special way. In detail, two separate loops are
used (master/slave), which consist of eight-piece segments lined up one after the other. The exact proportions
and the exact number of segments depend on the demands made on low overspill as well as the size of the room.
The smaller the segment, the smaller the overspill will be.
The master loop is laid over the entire area to be serviced. The slave loop is always one segment shorter than the
master loop and doesn’t begin until after the first segment half of the master loop. The individual segment lengths
should correspond to the distances between the seating rows.
We recommend using a single-strand cable, e.g. H07V-K with a cross section of 4mm², or the copper ribbon
cable (A-4937-0).
Advantages of a LOS induction loop design
- No loss of field strength in the centre of the induction loop
- No horizontal overspill
- No signal holes inside the loop
