Feedback Prevention:
Acoustic feedback occurs when sound from the PA loudspeaker nds it
sway back into the performer's microphone when the system is in use.
This unwanted audio signal can cause interference, noise, distortion or
plainly cause a non-desired and non-expected sound. Pyle PA speakers are
designed with more relatively at response rates to aid in minimizing any
type of unwanted feedback.
Factors involved with the elimination of feedback include proper system
placement: placing the system well in front of any performer and/or micro-
phone. Audio signal setting end con guration, along with EQ controls, can
help ne-tune the overall sound output which can be speci c to environ-
ment and type of audio generated by the loudspeakers.
The shape of the performance area (including performance area, elevation,
volume, etc.), the type of instrument being played, and vocals can all have
their relative own relative frequencies and unique sound prints which can
be uniquely a ected and picked up by any microphone.
