ILA-1000
™
The best result (constant field strength) is achieved by laying a „DOUBLE LOOP SEGMENT“ with phase shift.
Compatibility according to EN 60118-4.
Such double
LOOP SEGMENT induction loops are recommended for large areas and with large induction field
influence by metallic objects (walls and floors) in the concrete.
Application examples: large churches, exhibition halls, railway stations, schools, gyms etc.
Since the laying of the double LOOP SEGMENT induction loop is associated with quite a lot of effort, this type
of induction loops is usually only possible in new buildings or with general renovation of buildings.
The advantage of the DOUBLE LOOP SEGMENT induction loop is the up to 4 times lower loss of the induction
field (low power - large area).
For dual LOOP SEGMENT induction loops, the audio signal is connected to the first ILA-1000 LOOP amplifier.
This in turn supplies the first loop in the system.
Due to the phase modulation, the audio signal is shifted by 90˚ phases and forwarded to the second ILA-1000.
The second ILA-1000 then has to supply the second parallel induction loop throughout the system.
All LOOP segments should be equal and should not exceed ranges of 2 to 5 meters.
Compatibility according to EN 60118-4
In a „LOOP SEGMENT“ system, two ILA-1000s are always working together to form a magnetic field.
As a result, a uniform field strength of the magnetic field is always achieved over the entire surface.
The magnetic field outside the intended range loses strength rather quickly and drops to zero. This is done by
coupling a phase shifter FS-1, which is connected between the two ILA-1000, which in turn generates a signal
phase difference of 90 degrees in the electrical flow through two adjacent induction loops.
