INTRODUCTION
We at Phonic would like to congratulate you on
making the wise choice in investing in an all new
iA231F or iA231FD graphic equalizer, analog in
appearance, but purely digital on the inside.
The iA231F and 231FD are dual channel, 1/3 octave
31-band graphic equalizers with 6 or 12 dB of boost
or cut to ISO standard frequencies between 25 Hz
and 20 kHz, giving you, the user, ultimate control
over your audio quality in most any situation.
Featuring feedback elimination, a handy limiter
control, as well as a nifty high pass filter, allowing for
those troublesome and mind-numbingly pointless
low-frequency sounds to be removed without a
hassle, the iA series takes care of various needs
that any regularly equalizer would no doubt forget.
Provided your iA equalizer is used correctly, it should
provide you with many years of valuable use; which
is why we have included this handy user's manual.
Read on, dear friend, and you shall find tips and
hints and such, the likes of which no other equalizer
user's manual has ever offered. And if that doesn't
sell you on reading through this manual, perhaps
you could do it anyway, storing it afterwards in a
place you can remember and find later, if need be.
