AFP SWITCH
• OFF (reset): The anti-feedback function is turned off, the microphone
works in standard
mode and therefore any feedback could occur (just like any traditional
type of microphone). In this position, the yellow AFP LED on the receiver
front panel is off. Note: when the switch is in this position, all filters
previously inserted are eliminated.
• LOW: The anti-feedback function is switched on and the filter intervention
is soft and gradual; the AFP yellow LED is on. This position is recommended
for singing, especially when using a radiomicrophone / hand-held
transmitter and/or in very noisy environments.
• HIGH: The anti-feedback function is switched on and the filter
intervention is quick and decisive; the AFP yellow LED is on. This
position is recommended when using radiomicrophones very close to
loudspeakers or with clip-on microphones or in very quiet environments
(where even the feedback beginning could be annoying).
EXAMPLE - After connecting the receiver (power supply, audio, etc.), set
the AFP switch to the position suitable to the use (i.e. “HIGH” in the case of
a conference in a very quiet environment); make sure that the yellow AFP
LED on the front of the receiver is lit.
No other particular adjustments are necessary: once the transmitter is
switched on, the system is
ready to use.
Let’s suppose now that the speaker moves to another part of the room
while he is speaking.
In case a feedback occurs (due to the loudspeaker volume level and
position or also to the room form and dimensions), this will be immediately
identified and eliminated (instead of increasing exponentially). Moreover,
if the speaker returned to the same point again, the feedback would not
even begin, because one or more filters would have already been inserted
on feedback frequencies.
NOTE - All the filters in memory are eliminated when the microphone
receiver is switched off and also when the AFP switch is set to OFF position.
