WHY USE THE i7100?

There are a variety of caused of feedback, the most common
being when using microphone equipment (or common Public
Address Systems). At an ven of any sort a microphone may be
used to address the audience. The microphone works by picking
up the event host's speech, and translating that information to
an amplifier, which in turn sends the amplified audio out to the
speaker. However, if the audio contains any unusally high peak
level frequencies, these can be picked up by the microphonie,
sent through the amplifier and to the speakers again, only to be
picked up once more by the microphone. The process repeats
itself so quickly, amplifying the audio on each circuit, that it creates
its own frquency and produces the typical screeching or howling
noise synonymous with feedback. The whole process is commonly
known as looping, and by using the i7100 you can effectively
remove any unwanted loop conditions, while still retaining the
integrity of all desired audio.
The silencing of feedback can be a relatively simple thing. Aside
from the use of the i7100 Feedback Silencer, we also recommend
setting up any FoH (Front of House) system in a way that can use
the setting's acoustics to your advantage. After the initial setting
up of audio equipment. the i7100 feedback silencer can then be
applied to the mix to produce the clearest audio output possible.
