  • Page 8: Product Description

    Product Description The signal processor CD 44 is a digital 4 in 4-way speaker controller that can process both analogue and digital signals in the AES/EBU format up to 192 kHz. The controller is equipped with the finest AD and DA state-of-the-art converters as well as 3 micro-controllers and 8! integrated signal processors (DSP).
  • Page 9 31 Band One-Third Octave EQs A separate 31 band one-third-octave EQ is assigned to each of the CD 44’s four input channels. Up to 16 different EQ setups can be saved and administrated in an individual EQ setup library.

  • Page 10: Software And Firmware Update

    Software and firmware updates are necessary if Kling & Freitag LS-Blocks are made available for new speakers or the device’s range of function has been expanded. This ensures that the CD 44 will always be up-to-date and assured of a good future for speaker generations to come.
  • Page 11 If new LS-Blocks were copied to your hard drive, the Info window will show you where a log file was saved on your computer and under which name. If the update finished successful you can transfer the new LS-Blocks to your CD 44 system controller and use the K&F software normally.

    Ensure the soundness of the connectors. • If the AES/EBU signal is to be distributed over several lines of CD 44, then a special line splitter is necessary. If no special 110 Ohm AES/EBU cable is available, then data cables for lighting technology (DMX data cable with an impedance of 120 Ohm) can be used.
