8. Installation constraints

Some environments may interfere with magnetic
loops, here are the main causes:

8.1 External overspill

The installation of a simple loop system is ideal for
covering a room if the amplifier is properly sized,
however it is important to note that the magnetic
field of a loop will cover the interior of the room but
also the 'outside. The larger the loop, the greater
will be the overspill of it (note: in principle it takes 4
times the width of a loop to have a total isolation
zone). This phenomenon of external spill can be
problematic when it is necessary to equip several
side by side rooms or for confidentiality reasons.
To overcome this problem, it is possible to create
low overspill installations that will prevent the
radiation of the magnetic field. See sections 6.3.3 et
7.5.3.

8.2 Distortion due to metal

The metal according to created distortions on the
magnetic field in high frequencies and many
buildings contain
structures.
To limit this malfunction we have created a tone
compensation thanks to the MLC (for Metal Loss
Compensation) setting on the front of the amplifiers.
