 iA231F / iA231FD User's Manual

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 10 kHz, 
giving  you,  the  user,  ultimate  control  over  your  audio 
quality in most any situation.
Featuring  feedback  elimination,  a  handy  take-it-or-
leave-it delay 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.
