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 conguration, along with EQ controls, can help
ne-tune the overall sound output which can be specic to environment 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 aected and picked up by
any microphone.
