6.2.3 System composition
A magnetic induction loop system is composed of
:
• An amplifier
• One or more loops created with a conductor
• An audio signal (microphone or line)
• In some configurations a twisted pair cable (Opus
references: OP-LI5/10 or 15).
Refer to figure 15

6.3 The different types of installation

6.3.1 Simple loop
A simple magnetic loop is composed of an amplifier
and one or more induction loops.

6.3.2 The simple 8 loop or phased array
In some configurations, it will be preferable to use an
8 loop rather than a single loop to generate a more
intense magnetic field on the surface to be covered.
This type of installation improves the coverage area.
Why the "8" loop?
• A magnetic loop in the shape of a number 8
allows to reduce the crosstalk of the magnetic
field.
• It allows to cover a larger surface and to have a
better homogeneity of coverage.
• The current required is less important, so the
power consumption is also reduced.
