The local control panel gives access to all adjustable parameters and Panel provides status information for any of the cards in the Synapse frame, including the Synapse rack controller. The local control panel is also used to back-up and restore card settings. Please refer to the RRC18, RRC10,...
Ensuring that these precautions are followed will prevent premature failure from components mounted on the board. Locating the card The Synapse card can be placed vertically in an SFR18 frame or horizontally in an SFR08 or SFR04 frame. Locate the two guide slots to be used, slide in the mounted circuit board, and push it firmly to locate the connectors.
Default settings In the default condition, the DDP84 acts as a Dolby Digital Plus encoder locked to AES input 1, encoding AES 1/2 till AES 7/8 into a 5.1+2 Dolby digital plus output, using external incoming meta data program streams.
All menu items can be monitored and/or changed in this way. Changing a setting has an immediate effect. Cortex Cortex can be used to change the settings of Synapse modules from a PC, either locally or remotely. The software enables communication based on...

TCP/IP between the Setup PC and Synapse frames/modules. Each Synapse frame is addressed through its rack controller’s unique IP address, giving access to each module, its menus and adjustment items. Cortex has access to data contained within the Synapse module and displays it on a GUI.
Dolby E and encoding that into Dolby Digital (plus). Key Features The DDP84 is a stand alone Dolby Digital Plus encoder. It will support the following encoding algorithms: • Up to 4 times 2.0 Dolby Digital (Plus) outputs.
Cortex. SYSTEM CONTROL LockMode The DDP84 can be used as an ADD_ON card (in combination with an embedder/de-embedder card) In that case the card will extract the reference from the master card. In this case you are referred to the setting MasterCard.

Out_1 ~ Out_4 With these settings you can select what the sources should be for physical outputs 1 and 2, or bus outputs 1, 2, 3 and 4. Out_1 = physical output 1 and bus output 1 Out_2 = physical output 2 and bus output 2 Out_3 = bus output 3 Out_4 = bus output 4 Following sources are selectable:...
Page 13
INPUT CONTROL E_Input With this setting you can choose which Dolby E stream the Dolby E decoder should use. The input can be either one of the Add-on bus groups (AddOn1/2 till physical bitstream input AddOn7/8) (Bitstream_Inp). By default this is set to Bitstream_Inp. The lines and blocks that are marked red in the following schematic are done by this setting: Dolby_CH_1 ~...
Page 14
Delay_CH_1/2 ~ These settings allow you to delay the audio of each Dolby channel pair in Delay_CH_7/8 a range of 0 to 1300 ms. In steps of 0.01 ms. Default is 0ms. The lines and blocks that are marked red in the following schematic are done by this setting: Gain-CH_1 ~ These items allow you to gain the audio for each individual Dolby channel...
Page 15
Byp-Delay_1/2 ~ With these items you can adjust the delay of the AES1/2 till AES7/8 Byp-Delay_7/8 channels in bypass mode (when Out_1 till Out_4 are set to AES1/2, AES3/4, AES5/6 or AES7/8) can be delayed in a range of 0 to 1300 ms.

ENCODER CONTROL Enc_Input This setting lets you choose to either use the passed PCM channels (PCM) as encoder input, or the decoded Dolby E channels (Dolby E). You can also set this to Auto, meaning it will automatically switch to the input where a valid signal is available with Dolby E as priority.
Page 17
Enc_config With this setting you configure the encoder. The DDP84 supports multiple output formats. This always sets the maximum amount of channels (so metadata could change 5.1 to 2.0). Default setting is 5.1+2. Normal encoder settings: The following Enc_config settings are the normal settings. In the following table you see which settings have what outputs.
Page 18
= It is possible to embed a Pro Logic II encoded signal into a Dolby Digital (Plus) stream. This means that, out of a multichannel environment a Pro Logic II stereo signal is created. That stereo Pro Logic II signal is then passed on to the Dolby Digital (Plus) encoder to be embedded into a Dolby Digital (Plus) audio stream.
Page 19
Enc1_mode ~ With this setting you can set the Dolby Digital mode in which each Enc4_mode encoder should function. The following settings are possible: DD+_Man = Dolby Digital Plus mode, with a manually set bitrate (refer to Enc1-DD+_Man ~ Enc4-DD+_Man to set the bitrate) DD+_Auto192 = Dolby Digital Plus mode, automatically set to a bitrate of 192 kbps.
Page 20
Enc1_DD+_Man This item manually sets the used audio bitrate of the Dolby Digital Plus mode when the corresponding Enc_mode is set to DD+_Man. Can be Enc4_DD+_Man between 32kbps and 1532kbps. The following table displays all the possible steps in between. Lowest bitrates can not be selected in 3/2 (in other words: 5.1).

PROLOGIC CONTROL The lines and blocks that are marked red in the following schematic are done by this chapter’s settings: Meta_source This item lets you select which metadata source you want to use for pro logic encoding, external (External_MD, using program 1) or internal (Internal_MD, using Metadata set A).
Page 22
LFE-MixLevel This setting indicates the level shift applied to the LFE channel when adding to the left and right outputs. -6dB, -3dB and –0dB PL_delay Sets the Pro Logic delay between 0smpls and 1536smpls. Default is 1024smpls. META CONTROL MD_enc1 ~ These items let you select a program inside the external Metadata source or the incoming Dolby E signal to use with encoders 1 till 4.

DOLBY D METADATA The lines and blocks that are marked red in the following schematic are done by this chapter’s settings: #Metadata_set With this item you can select which metadata set you want to adjust parameter setting of. Possible are A till H. Default is set to parameter set A. All following items preceded with ‘#’...

The bitstream is the main audio service for the M&E program, minus a dialogue channel. The dialogue channel, if any, is intended to be carried by an associated dialogue service. Different dialogue services can be associated with a single ME service to support multiple channels.

Music Stnd, Applies more compression to music that is not compressed and requires dynamic range restriction. Music light, Applies light compression to music that is already compressed and does not require excessive dynamic range restriction. Speech, Appropriate for programs with predominantly dialogue. You can also choose to use the metadata settings in the external program (Ext_meta, only usable when the MD_enc1 till MD_enc4 are set to MxA till MxH)

#Lt/Rt C dwnmx Lr/Rt Center Mix Level. This setting indicates the level shift applied to the center channel when adding to the left and right outputs when downmixing to an Lt/rt output. Its operation is similar to the surround downmix level in the Universal metadata.

This setting is used to identify the encoded audio as surround EX encoded material.

#Lowpass Filter Lowpass Filter. This setting determines whether a lowpass filter is applied to the main input channels of a Dolby Digital encoder to encode. This filter removes high frequent signals that are not encoded. At the suitable data rates this filter operates above 20 kHz. In all cases it prevents aliasing on decoding and is normally switched on.
6 Status Menu Introduction The status menu indicates the current status of each item listed below. Ref-Stat Displays the status of the B&B reference input on the RRC/RRS. Can be a 30Hz ref, a 25Hz ref or NA (not available, meaning no reference input detected).
There are several means by which the message can be filtered. DDP84 Events The events reported by the DDP84 are as follows; Announcements Announcements is not an event. This item is only used for switching the announcement of status changes on/off.
Page 32
In cases where the event marks a change to fault status (e.g. 1 for Loss of Input) the complement is marked by the tag increased by 128 (80 ) (e.g. 129 (81 ) for Return of Input). Defining Tags The tags defined for the DDP84 are: Event Menu Item Description Announcements 0 or NA...
