5.5 Operating level Switch
To adapt the FEEDBACK DESTROYER PRO to the used operating level, the unit can be switched between
homerecording level (-10 dBV) and professional level (+4 dBu). Use the LED bars on the frontpanel to deter-
mine the optimal setting. The Level indicators should read somewhere between -10 and -6 dB, while the clip
LED should not light up at all.

6.1 Frequency chart
In order to maintain a better survey only every second value is registered in the table. The adjustable values do
not exactly fit into a 1/60 octave interval, because also the ISO frequencies do not perfectly fit into a physical
1/3 octave interval. Rather a linear approximation is used to specify the values.
