Fulgor Services specialise in the design and manufacture of
audio systems for places of worship and have systems installed in many of the most iconic religious venues on three
continents. They offer attractively styled passive column
speakers and control systems like many manufacturers, but
they also have a range of active column array speakers.
These Speakers have built in amplifiers and signal processing
providing volume control, equalisation, time delay and even
beam steering. Using a unique power supply that carries
both power and audio signal on just 2 wires in many venues
there is often no need to install new cables as the existing
speaker cables will do even if they are daisy chained. Where
new cabling is required, it is only a single twin core
1mm2cable which is easy to install and conceal.
Univox Audio will provide technical advice, training,
system design and specifications to help you select the best
and most cost effective solution

Induction Loop Systems
Your venue needs a standard compliant induction loop
system to guarantee access for your hard of hearing
members and guests.
Perimeter loops are not always the best solution. There
are many other loop configurations that may be more
appropriate to meet the requirements in your venue eg.
Figure 8, Cancellation, Super 8, super loop etc.
Hard of hearing people find it particularly difficult to
distinguish between background noise and the speech
that they want to listen to. Reverberation is background
noise, acceptable levels of reverberation for someone with
good hearing are much higher than those for someone
who is hard of hearing. No matter how much improvement we can make to the levels for reverberation and
other sources of background noise it is unlikely to be good
enough for the hard of hearing. Instead we rely on assistive
listening technology such as induction (hearing) loops.
All assistive listening technologies work on the same principle, they filter out the background noise and deliver just
the wanted sound to the listener.
Perimeter loop
Perimeter loops; easy to install. Provide no compensation
for metal loss. Spill field is 1 to 2 times the width of the
loop
If you want to speak to someone in a crowded noisy room,
you will get a little closer to them and speak directly into
their ear, and that is exactly what happens when you use
an induction (hearing) loop system. When you speak into
the microphone of an induction (hearing) loop system it
is like speaking directly into the persons ear.
Cancellation loop
Cancellation loops; easy to install. Provide good
spill control in 1 direction. Do not provide metal loss
compensation
The microphone provides a high level of rejection to the
background noise and just conveys the wanted speech.
In the simplest form of induction (hearing) loop system,
the speech is converted into a current which is driven
round a loop of cable encompassing the venue. The current
sets up a magnetic field which turn induces a current into
the pick-up coil (T-coil) of the person’s hearing aid. This
current is amplified and tonally corrected for the individuals
hearing loss and fed into their ear via the speaker in the
hearing aid. Induction loops are not only universal, they
are the only assistive listening technology that provide a
customised signal tailored to everyone’s hearing loss.
