Super Loop System
®
SLS is a balanced
uncorrelated induction loop system. It consists of two
separate loop systems (Master and Slave) with a separate
current controlled amplifiers connected to each loop.
UniVox
®
SLS systems have several advantages compared to
old conventional loop systems:
● Almost no vertical and horizontal overspill
● Smoother field strength level
● Highly increased frequency response
● Less impact on field strength and high frequency range
by reinforcements or other metal construction parts
● Less directional sensitivity (no level drops when tilting
the head)
● Increased efficiency due to controlled field strength
● Highly reduced risk for interference with other
electronic equipment, guitars, microphones, etc.
There are many possibilities for the layout of the loop wire,
but the basic UniVox
®
SLS system for most installations
is the same: A Master loop which covers the whole
listening area and a Slave loop, slightly smaller compared
to the Master loop. The size of the segments controls the
overspill, both horizontal (sideways) and vertical (sitting
vs. standing). In theatres or cinemas the segment size is
simply the same as the distance between the seating rows
for ease of installation (with UniVox
®
SLS there is no field
strength drop above the crossing of the wires). 1 meter
segment size is normally fine but other segment sizes could
be recommended depending on the installation.
After the installation of wire and loop amplifier, the whole
system has to be certified. Both installation and adjustment
has to be performed by trained staff equipped with a field
strength meter and basic knowledge of how the system
works and how loops are measured and adjusted. Contact
your distributor for all questions regarding projection,
installation and adjustment of the system. You can find more
information at www.edin.se where also a drawing tool for
planning is available on-line (contact your distributor for
log-in data).
The UniVox
®
SLS example on the right is created with the
above mentioned on-line planning tool on our web site. It
is recommended that the direction of attention or “looking
direction” should preferably be across the segments. The
size is 12 by 8 metres with 8 segments and thus a segment
size of 1,5 m. The amount of wire needed for the Master
and Slave loops is indicated at the bottom of each drawing.
