The Sony Intelligent Feedback Reducer
can suppress unwanted feedback (howling)
with high-performance DSP and Sony’s unique
algorithms designed to eliminate feedback
before it becomes unbearable. Up to 1024-band
suppression filters are continuously tuned
automatically in real time, eliminating feedback
and avoiding deteriorating the original signal;
this delivers the highest quality sound that can be
enjoyed by presenters, vocalists, and audiences.
You can freely select the audio outputs to
which you want this feedback reduction filter to
apply – for example, you can output original
audio to the main PA system, while processed
audio is delivered to your monitor speakers.
