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.
