  • Page 2: Technical Specifications

    3G/HD/SD-SDI embedder / de-embedder with a 16ch DSP. For a start it can be treated as the successor of the C8491. The C8492 can be purchased as a four / eight or 16 channel processor (C8492-x) with surround option (C8492-xS) or without it.

  • Page 4: Initial Setup

    = CAN bus speed 1Mbit/s Important Note! For a limited number of modules like the C8492 it is possible to communicate with a CAN bus speed of 1MBit/s. This provides more bandwidth to move measuring data from the module via the frame controller to the J*AM based loudness logger.
  • Page 5 A 5.1 downmix from the surround input is also available then. Finally, if the bus access option (B) is purchased the C8492(B) may be interconnected with other c8k modules to form highly complex signal chains.

  • Page 6: Status Pane

    4/8/16 channels DSP with SDI & system-bus I/O STATUS PANE The status area is quite big for the C8492 so you may face difficulties when displaying it on lower resolution displays. You may shrink it by pressing on the little "fly foot print":...

Otherwise you may experience malfunctions. FIRMWARE displays the firmware versions of the C8492 components: Controller The module controller...
  • Page 11 ROUTING only available for C8492(B) You may purchase the (B) option that expands the capabilities so the module can be used in standard c8k applications together with other c8k modules to allow for Dolby processing, AES / MADI or even analog break out for example.
  • Page 12 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O The bus interface allows for very flexible interconnection from and to the c8k audio busses, either in two channel or eight channel multiplex mode, as well as the connection from and to the SDI embedder / de-embedder.
  • Page 13 (See SMPTE 2020 for reference of VANC metadata embedding). Important Note! This transport mechanism is not compatible with the previously used proprietary technology from Junger. I.e. you can not interconnect legacy Dolby modules with the C8492(B) for metadata transport. We recommend using the successor platform C862x (C8621 Dolby Decoder, C8631 Dolby E encoder and C8632 Dolby Digital / Digital plus encoder).
  • Page 14 C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O Important Note! The remainder of this manual refers to the C8492-16S version (16 channel and surround license enabled). Some settings are impossible for a four channel license, but the parameters for the audio processor are the same.
  • Page 15 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O Stream Select (3G-B) [Stream 1 / Stream 2] For 3G-B SDI operation (see SMPTE 372 for details) you must select which of the two streams runs through this particular module.
  • Page 16 4/8/16 channels DSP with SDI & system-bus I/O DSP 1A - 4 x 2 mode From here you can control the audio parameters of the C8492 function blocks. For detailed explanation of the LevelMagic parameters pls. see the separate document: Junger_Processing-Parameters_xxyyzz.pdf which you may download from our web site.
  • Page 17 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O Link [Unlinked / Linked] defines the coupling of the control circuits in order to maintain the listening balance for correlated signals or to provide a grouping of the setup parameters for multi channel signals.
  • Page 18 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O Proc Status Enable [ON / OFF] If the average gain of the module is equal or above the Leveler Max Gain for more than 10s the respective Processing Status soft LED turns red.
  • Page 19 DSP 1B – 4 x 2 mode The C8492 offers the feature to use pairs of channels in a fail over mode. I.e. if the audio signal fails in the first audio pair, the processor may switch over to the adjacent (e.g. 1/2 >> 3/4) pair automatically.
  • Page 20 As mentioned above there is also a 5.1 + 2 program configuration available if you have bought the surround option for the C8492. In this case the first 6 channels of the DSP are linked for surround processing. This will also apply to DSP 1 if 5.1 + 2 is selected. The example above shows a condition where the LFE is not linked to the other surround channels and may be controlled independently.
  • Page 21 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O DSP 2B – 5.1 + 2 mode If you have bought the surround option you will get the option to do an upmix either for permanent operation or as a fail over feature to maintain a surround image if the input surround signal disappears.
  • Page 22 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O Mode [Primary / Secondary / AUTO / AUTO no Upmix] You can select between one of the 2ch inputs and the auto mode and auto mode with upmix disabled (e.g. for path through of announcements).

  • Page 24 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O Surround Balance [0.00 … 1.00] Mono defines the amount of direct sound mixed into the surround channels. 0.0 provides pure ambient sound while 0.1 to 1.0 will increase the amount of direct sound.
  • Page 25 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O DE-EMBEDDER Here you may assign the audio signals from the 16 de-embedded channels to up to 16 processing channels. Important Note! The number of processing channels may be different. It depends on the license that is activated for the module.
  • Page 26 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O EMBEDDER From here you can control the embedder. You may select between the 16 audio channels from the input (de-embedder) and the signals from the processors (DSPs).
  • Page 27 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O SDI Grx Enable You must check these check boxes to enable the respective embedder. The check boxes show flashing red frames as a warning as long as no embedder is turned on. The respective column of the local (embedder) routing matrix for each group is not high lighted as long as its embedder is not enabled.
  • Page 28 C8000 modular processing system C8492(B) 4/8/16 channels DSP with SDI & system-bus I/O SDI Generator Mode [AUTO (Input Loss) / ALWAYS ON / OFF] If the generator is set to "AUTO (Input Loss)" and the input signal is lost, the generator will use the pre-selected video format from the setting below.
  • Page 29 4/8/16 channels DSP with SDI & system-bus I/O GPIO The C8492 has three dedicated sets of GPI/Os for the DSP, the SDI and the Failover/Upmix. Moreover it offers the function to clear the DSP history (see level magic expert parameters) by control of an external GPO device.
  • Page 30 The c8k frame can handle 127 different virtual (system) GPO numbers. If an event occurs, the C8492 puts the assigned number on the CAN bus so a C8817 GPI/O module can engage a relay or the brc8x may activate its tallies.
