Capabilities
Synapse is a modular system designed for the broadcast industry. High
density, intuitive operation and high quality processing are key features of
this system. Synapse offers a full range of converters and processing
modules. Please visit the AXON Digital Design Website at www.axon.tv
to obtain the latest information on our new products and updates.
The local control panel gives access to all adjustable parameters and
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,
RRC04, RRS18 and RRS04 manuals for a detailed description of the local
control panel, the way to set-up remote control over IP and for frame
related settings and status information.
The remote control options are explained in the rack controller
(RRC18/RRC10/RRC04/RRS18/RRS04) manual. The method of
connection to a computer using Ethernet is described in those manuals as
well.

CHECK-OUT: “CORTEX” SOFTWARE WILL INCREASE
SYSTEM FLEXIBILITY OF ONE OR MORE SYNAPSE
FRAMES
Although not required to use Cortex with a Synapse frame, you are
strongly advised to use a remote personal computer or laptop PC with
Cortex installed as this increases the ease of use and understanding of the
modules.

2 Unpacking and Placement
Unpacking
Locating the card
The Axon Synapse card must be unpacked in an anti-static environment.
Care must be taken NOT to touch components on the card – always handle
the card carefully by the edges. The card must be stored and shipped in
anti-static packaging. Ensuring that these precautions are followed will
prevent premature failure from components mounted on the board.
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.
Correct insertion of card is essential as a card that is not located properly
may show valid indicators, but does not function correctly.
Note: On power up all LEDs will light for a few seconds, this is the time it
takes to initialise the card.

When Powering-

Changing settings
and parameters
Front Panel
Control
On powering up the Synapse frame, the card set will use basic data and
default initialization settings. All LEDs will light during this process.
After initialization, several LEDs will remain lit – the exact number and
configuration is dependant upon the number of inputs connected and the
status of the inputs.
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.
The front panel controls or Cortex can be used to change settings. An
overview of the settings can be found in chapter 5, 6 and 7 of this manual.

The DDP84 Card
Introduction
Application
Key Features
Dolby Laboratories, with Dolby Digital Plus, is targeting at the next
generation of digital transmission and optical formats. The advantage of
Dolby Digital Plus is a channel count of up to 7.1 (13.1 in the future) and
bit rates of about 50 percent of normal Dolby Digital.
The calculation power of the DDP84 make a simultaneous encoding of 4
individual stereo channels (languages) to 4 Dolby Digital (Plus) 2.0
streams. It can even decode Dolby E to encode the decoded audio to
Dolby Digital (Plus).
An important application is the transcoding of normal Dolby Digital to
Dolby Digital plus for cable head-ends. This gives a data rate reduction of
50% for the audio path. The DDP84 includes a Dolby E decoder. This
enables the decoding of Dolby E and encoding that into Dolby Digital
(plus).
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.
• 5.1 Dolby Digital (Plus) + 2.0 Dolby Digital (Plus)
• Dolby Pro Logic II
• Individual offset delay per input
• Individual gain control per input (except bitstream input)
• Able to handle all AES/EBU input formats
• Full audio channel shuffling
• Ability to use the Synapse ADD-ON bus for in- and output
purposes.
• Decoding Dolby E and encoding to Dolby Digital (Plus)
Program
Procedure
This card can be updated with new firmware when new firmware versions
are released by Axon. You can download the .spf file from our website
when new releases are announced. To upgrade the DDP84 you can follow
the instructions as described in the ‘reprogramming cards quick-guide’,
downloadable via our website.
When the DDP84 is updated with a new .spf file, the card will need about
6 minutes to start up after the card is ready programming. All LEDs will
be blinking and the encoder status item (in de status menu) will be
indicating ‘programming’. Only the input LEDs are showing the
progress.

5 Settings Menu
Introduction
LockMode
The settings menu displays the current state of each setting within the
DDP84 and enables the item to be changed or adjusted.
Settings can be changed using the front panel of the Synapse frame
(SFR18, SFR08 or SFR04) or Cortex.
Please refer to chapter 3 for information on the Synapse front panel
control and Cortex.
SYSTEM CONTROL
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. It is also possible to use an external signal to lock to. In that
case you are referred to the setting:
AES1 = Locks to the AES/EBU signal on input 1
AES5 = Locks to the AES/EBU signal on input 5
Ref1 = The uppermost B&B reference input of the RRC18 rack
controller connection panel at the rear of the SFR18
Ref2 = The lower most B&B reference input of the RRC18 rack
controller connection panel at the rear of the SFR18
Default setting is: AES1.
Add_on
With this setting you set the add-on functionality of the card (the 4
Synapse bus connectors) to be either Inputs, Outputs or 2 inputs and
2 outputs (In_Out_In_Out, setting the first add-on card as input, the
second as output, the third as input and the fourth as output). Default is
Inputs. The lines and blocks that are marked red in the following
schematic are done by this setting:
11
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:
- enc1 = Encoder 1
- enc2 = Encoder 2
- enc3 = Encoder 3
- enc4 = Encoder 4
- aes1/2 = First physical input (can be delayed in bypass mode)
- aes3/4 = Second physical input (can be delayed in bypass mode)
- aes5/6 = Third physical input (can be delayed in bypass mode)
- aes7/8 = Fourth physical input (can be delayed in bypass mode)
- bitstream = Fifth physical input: Dolby Digital, Dolby E or PCM
(no bypass delay possible)
- testtone = Testone for testing the chain where the DDP is part of
Defaults for outputs 1, 2, 3 and 4 are respectively enc1, enc2, enc3 and
enc4.
