Signal at
S-C-Insert |
- depends on the Operation Mode
- Filter Mode, Low Band compressed:
Side Chain Insert is located in High Band
- Filter Mode, Hi-Band compressed:
Side Chain Insert is located in Low Band
No Filter Active:
Side Chain Insert is located in the Side Chain
|
| Display |
- Gain-Reduction with 20 Led's, 1 to 30 dB
|
|
| Filter |
- Phase-corrected Split Filter 12 dB/Oct.
with Split Frequency Control
|
| Range |
- Standard 40 Hz to 320 Hz
Custom Frequencies are possible

|
| MS Matrix |
can be inserted pre and post Compressor
when aktiv, the Compressor treats the M/S instead of the Left/Right Signal |
| Side Chain Balance |
Control with Center Detent
Controls the Relation between the Channels in the Side Chan
in LR Mode between Left and Right
in MS Mode between M and S |
|

- Compressor not active
- (Ratio-Regler all to the left)
|
|
- 3)
- The settings and the signal frequency can affect the THD values. The values refer to inactive regulation.
