no Changes at Threshold Level
Gain-Change
- 10 dB via 0 dB to + 10 dB
Boost or Cut in active Rahne
+ 10 dB Gain-Change = 10 dB Boost at Center Frequency, when Level is 10 dB different from Threshold
Clamp
Limits maximum Boost/Cut
from ±3 dB to ± 10 dB
Display Boost / Cut with 9 Leds ± 12 dB

1)
Depending on the setting of the control, gain or attenuation is possible. The value is valid for the higher level at the input or output.

2)
Dynamic Control not active
(with Gain-Change at 0)

3)
The signal frequency and the setting can affect these values. The values refer to inactive regulation(with Gain-Change at 0)
