    C8000 modular  processing system C8305 64ch BNC MADI I/O technical specifications MADI interface: standard: AES 10 (2003) connection: BNC 75Ω signal level: 800mV ±10% data format: 24bit transparent for C- and U-bits according to AES3 sample rate: 48kHz (24bit = max. 64 channels) 96kHz (24bit = max.
  • Page 3: Installation

    SW2 = ON enables the CAN “+16” address schema to handle up to 32 modules. Important Note! In case of MASTER mode, the C8305 must be installed into one of the red colored fitting rails at the rear of the frame.

  • Page 10 Great care must be taken to avoid same numbers assigned to different functions! Because it will activate multiple functions, causing great confusion in bigger installations, e.g. where Junger HW remote controller is in place or GPIs are connected with automation systems.
  • Page 11 Great care must be taken to avoid same numbers assigned to different functions! Because it will fire same GPO (Tally) by different functions, causing great confusion in bigger installations, e.g. where Junger HW remote controller is in place or GPOs are connected with other management systems. There is no mechanism implemented to check for doublets Jünger Audio‐Studiotechnik GmbH ...
