Fulgor Service Automatic System
To activate the automatic control of the inputs, check the box "Abilitato".
From this section it is possible to check and/or modify the parameters of the automatic system developed by Fulgor Service and check the
status of the inputs.
The example graph on the right shows the operating principle of the automation.
Parameter Value Function Example
Attenuazioni Negative (dB)
Set the attenuation to inputs
that are not working
Settings -15dB; 15dB
attenuation is applied to the
inputs that are not working and
that have the check mark on
“automixer”
Differenza di livello per
diventare leader
Positive (dB)
Settings -15dB; 15dB
attenuation is applied to the
inputs that are not working and
that have the check mark on
“automixer”
3dB setting; the working input
with the tick on “automixer”
are checked and the one that
exceeds the other by 3dB
becomes (in that moment) the
leader
Num. max ingressi aperti in
simultanea
Number
Settings -15dB; 15dB
attenuation is applied to the
inputs that are not working and
that have the check mark on
“automixer”
Setting 3; only 3 of the inputs
that have the tick on
“automixer” will be able to
work simultaneously
Differenza di livello
apertura in simultanea
Negative (dB)
It sets the maximum difference
that the working inputs must
have with respect to the leader
to be actually open
Setting 7dB; if the inputs that
have the tick on “automixer”
reach a minimum level within
7dB respect to the leader (ex.
the leader reaches -7 dB ▶
minimum opening level -14dB)
they will be open, otherwise
they will remain closed.
N.O.M.A. Number of Open Microphones
Attenuated
Keeps the output level constant
depending on the number of
microphones actually open
If a microphone is working, the
system does not intervene, as
you add (open) microphones,
the system intervenes by
decreasing the mixer output
level in percentage to have a
constant level
Sensibilità minima di
apertura degli ingressi dB
It decides what is the minimum
level that an input must reach
in order to be opened
-40dB setting; if the inputs
with the check mark on
“automixer” reach at least -40
dB they can be opened

Filters Editor
3 filters are available for each
input:
It is possible to select the
Frequency (Freq.), the merit
factor (Q) that determins the
slope and type of filter, i.e. low-
bass (LP) – high-pass (HP) –
parametric (EQ)
👉 By choosing a low-pass or a
high-pass the merit factor is
raised automatically to 0,5
👉 By choosing the parametric,
the filter will have a slope directrly
proportional to the merit factor Q.
A very low Q will give a narrow
filter, vice versa it will give a wide
filter.

ANTILARSEN
DELAY
DELAY
D
From this section it is possible to enable an antilarsen for each output.
Phase type antilarsen bases its functioning on phase modulation managed by an algorithm
developed by Fulgor Service
Freq type antilarsen (Frequency) bases its functioning on the frequency shift managed by an
algorithm developed by Fulgor Service, which uses the principle of traditional analog antilarsen
👉 With Phase antilarsen it is suggested to set the “Delay Antilarsen” to 1,8ms. and the
“Velocità (speed) Antilarsen” to 1,80Hz
👉 With Freq antilarsen Freq the “Delay Antilarsen” is locked and the “Velocità (speed)
Antilarsen” should be adjust between 1 and 1,80Hz

19
Features can be modified without any notice V2020319
DELAY
From this section it is possible to enable a delay for each output.
The delay is expresssed in meters to facilitate the calculation (reference temperature 20°C)
👉 The maximum delay that can be set is 64 meters equal to approximately 186ms

20
Features can be modified without any notice V2020319
NOISE GATE
From this section it is possible to enable a noise gate for each output by clicking on “on”.
The adjustment parameters allow you to set the functioning minimum level, the delay in
intervening and the “speed” with which it intervenes.
“Soglia Intervento”: between -40dB and +1dB; the noise gate intervenes when it reaches or
below the selected threshold
“Ritardo Intervento”: between 0dB and 10dB; once the threshold has been reached, the noise
gate waits fora time equal to the value selected before intervening
“Pendenza di Chiusura”: between 0,1 and 5 expressed in dB/sec; once the threshold has been
reached and the selected time has elapsed, the noise gate closes the output with a slope qual
to the chosen one; this parameter can also be considered as closing speed since the higher it
is, the faster the minimum level is reached.
👉 When the noise gate intervens, the light next to the writing Gate changes color
👉 Under the adjustment sliders there is a VuMeter of the output
