User’s Manual Digital Controller CD 24 Select LSBlock → Flat The LSBlock 'Flat' is a distinctive feature. It is intended for special uses such as processing or transmitting line signals, or using third party products or Kling & Freitag speakers where no LSBlock is available. In this LSBlock, all filters are switched off, and there is also no subsonic filter intended! It is still possible, though, to equalise signals with the help of the PEQs.
User’s Manual Digital Controller CD 24 Amp Amp Gain This is where the CD 24 shows the determined amplifier gain of the power amplifiers connected to the SENSE / RETURN connectors. After switching off the unit the settings always stay at the last plausibly determined value. As soon as a signal that can be analysed by the controller is applied to the Sense connectors, the controller determines the gain of the connected power amplifier.
User’s Manual Digital Controller CD 24 Rights The controller differentiates between three different authorization modes which we will, at this point, call User, Master, and Lock Mode. Lock If you select the settings Util → Rights → Lock, Lock no more changes can be made to the controller. This setting serves to completely protect the device from nonauthorised persons. To activate this setting, you will be asked for the password. You can enter the User or Master password.
