2.5 Advice and safety

Most of defective loop installations are the result of
a lack of preparation. Take your time before starting
your installation and always keep this manual in an
accessible place.
Ideally, the loop driver should be placed near the
area to be covered. This may involve placing the loop
driver on a panel/wall, under a desk or under a
counter. Wall mounting accessories are provided in
the OP-R mounting kit.
Refer to figure 9 on page 13
To chose the location for your loop, take into
consideration the area that would be most likely
used by the end user. This area is called the
"listening area".
For exemple, in a concert hall, you'll install your loop
cable around the audiance area rather than the
whole room. Covering also the stage may lead to
feedbacks effect due to a conflict between the loop
magnetic field and the dynamic microphones (guitar,
bass..) of the band playing on the stage.
