Wide indoor environment setting
MICROPHONE SETTING MENU
The IG2T allows the input of a microphone with XLR connector. When
using this source, it may be useful to apply a ltering to the signal to
cut any unwanted frequencies (by a high-pass lter with adjustable cut
frequency). Or it may be necessary to intervene (by a notch or band-stop
lter with selectable band centre) to prevent any feedback (or Larsen
effect). To perform one of these settings, or both of them, after accessing
the MICROPHONE SETTING menu:
1. Select and conrm HP lter (high-pass lter)
2. Select and conrm the value of the high-pass lter cut frequency, with
a range of 50 Hz – 200 Hz and a resolution of 10 Hz (select the “None”
value if you wish to disable the lter)
3. Select and conrm “Antifeedback” (anti-feedback or anti-Larsen effect
lter)
4. Select and conrm the value of the band centre frequency, with a
range of 260 Hz – 15000 Hz and a resolution of 10 Hz (select the
“None” value if you wish to disable the lter)
5. Return to the initial screen by selecting the “HOME” symbol
