Introduction to Synapse
An Introduction to
Synapse
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.
Local Control Panel
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 rack
controller 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.
Remote Control
Capabilities
The remote control options are explained in the rack controller manual.
The method of connection to a computer using Ethernet is described in
those manuals as well.
!
CHECK-OUT: “AXON CORTEX” SOFTWARE WILL
INCREASE SYSTEM FLEXIBILITY OF ONE OR MORE
SYNAPSE FRAMES
Although not required to use Axon Cortex with a Synapse frame, you are
strongly advised to use a remote personal computer or laptop PC with
Axon Cortex installed as this increases the ease of use and understanding
of the modules.

Unpacking and Placement
Unpacking
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.
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.
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.

9
3
A Quick Start
When Powering-up
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.
Default settings
In the default condition, the DEE28 acts as a Dolby E decoder locked to
ref input 1, decoding into AES outputs using external incoming meta
data program streams.
Changing settings
and parameters
The front panel controls or Axon 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 DEE28 Card
Introduction
The DEE28 is a next generation Dolby multi format decoder and Dolby
E encoder with quad speed ADD-ON audio bus. It replaces the popular
DBD08 and DBE08 on a single card. Based on the Dolby’s Cat. No.
1100 sub module it is capable of decoding Dolby E, Dolby Digital and
Dolby Digital Plus and encoding to Dolby E. The enhanced feature set
includes the capability of decoding 7.1-channel Dolby Digital Plus or
5.1-ch Dolby Digital 5.1 with audio description, carried in a single
bitstream (Single PID), or as two bitstreams (Dual PID).
In addition to the extensive Dolby Decoding capabilities this card can
add a voice activated (or triggered by GPI) Voice Over signal to any of
the decoded streams or plain PCM streams that could enter the unit.
Individual delay and gain controls are available for all decoded or plain
PCM streams that entered the card. A dual mode I/O configuration is
possible with physical 2x AES/EBU in and 6x AES/EBU out or 4x
AES/EBU in and 4x AES/EBU out.

Settings Menu
Introduction
The settings menu displays the current state of each setting within the
DEE28 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 Axon Cortex.
Please refer to chapter 3 for information on the Synapse front panel
control and Axon Cortex.
SYSTEM CONTROL
SRC
The AES/EBU inputs are connected to a Sample Rate Converter. This
enables the input to use audio sample rates that are non-synchronous to
video of the master card (setting On). For Non PCM audio data (Dolby
Digital, Dolby E, etc.) the SRC can be bypassed and the data is inserted
in the card transparently (Trans). The default setting is On.
Lock-Mode
The DEE28 can be used as an ADD_ON card (in combination with an
embedder/de-embedder card). In this case you are referred to the setting
MasterCard, which will extract the reference from the master card. 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(default)
AES4 = Locks to the AES/EBU signal on input 4
Ref1 = The B&B reference input of the rack controller
Ref2 = The second B&B reference input of the rack
controller (if available)
Mastercard = Locks to the ADD-ON bus input (always use
this setting when using quad speed add-on bus
functionality).
Backup
This is the backup input enable/disable for the Dolby decoder. Set to on
will switch the decoder outputs to the assigned backup channels when
dolby is lost. Which channel will be the backup channel is set with
Dolby_PCM_backup and Ch_Backup. The delay compensation of
the backup is always 1 frame (equal to Dolby E decoding).
In_Out
In the block schematic you can see that 2 of the 4 AES inputs and 2 of
the 6 AES outputs are colored grey. With this setting you decide which
inputs and outputs are active. There’s two possible settings:
■ 4In-4Out: 4 AES/EBU input and 4 AES/EBU outputs
■ 2In-6Out: 2 AES/EBU input and 6 AES/EBU outputs
Refer to the block schematic for more details on the difference modes.

15
Dolby_firmware
Please only change to No_Update when told so by Axon Support.
Output_1_mux ~
Output_4_mux
With these setting you can choose to either route the default channels to
the output muxes (CH1/2 for output 1, CH3/4 for output 2, CH5/6 for
output 3 and CH7/8 for output 4) or to route the encoded Dolby E
signal to the specific output.
INPUT CONTROL
Dolby _in
Here you select where the Dolby E comes from: from the local
AES/EBU inputs, or from the master card via the add-on bus. Default
is local. Please note that when set to master the lock-mode setting
should also be set to mastercard.
Ch_main_in
With this setting you appoint specific channels within the input source
set with Dolby_E_in, which should contain Dolby E. Dependant on
the source, you can choose any of the following audio pairs:
■ 1/2 AES/EBU input 1 when source is local, Add-on
bus channels 1/2 when source is master
■ 3/4 AES/EBU input 2 when source is local, Add-on
bus channels 3/4 when source is master
■ 5/6 AES/EBU input 3 when source is local, Add-on
bus channels 5/6 when source is master
■ 7/8 AES/EBU input 4 when source is local, Add-on
bus channels 7/8 when source is master
■ 9/10 only available when source is master
■ 11/12 only available when source is master
■ 13/14 only available when source is master
■ 15/16 only available when source is master
■ 17/18 only available when source is master
■ 19/20 only available when source is master
■ 21/22 only available when source is master
■ 23/24 only available when source is master
■ 25/26 only available when source is master
■ 27/28 only available when source is master
■ 29/30 only available when source is master
■ 31/32 only available when source is master
Dolby_PCM_backup
With Dolby_PCM_backup you select which source is your backup
input for the Dolby decoder (only used when Backup is set to on). Can
be set to local (the physical AES/EBU inputs) or to master (audio
coming from master card, via add-on bus). Default is local.

16
Ch_backup
With this setting you appoint specific channels within the input source
set with Dolby_PCM_backup, which should contain Dolby E.
Dependant on the source, you can choose any of the audio pairs listed
under Ch_E_in.
Sel_Ch1 ~ Sel_Ch16
With these settings you set a source for the corresponding output
channel. You can set each individual channel to source:
 Local: physical AES/EBU inputs
 Master: audio coming from master card via add-on
 Decoded_PCM: audio coming from the Dolby decoder
 Monitor: this is the monitoring output of the decoder. This
channel contains for instance a downmix or audio description.
 LoudnessLVL: this is a representation of the loudness level as a
PCM signal (a 1Khz sine). This signal can be put on a normal
audio level meter to represent the loudness measurement.
Channels 1 till 8 (dependant on the In_Out setting) are the physical
AES/EBU outputs as well as outputs towards the add-on bus and are by
default set to Decoded_PCM. Channels 9 and 10 are default set to
Monitor. Channels 11 till 16 are add-on bus only (dependant on the
In_Out setting) and by default set to Master.
Ch_1 ~ Ch_16
With these settings you select the actual source channel in the above
selected source. Default Ch_1 till Ch_16 are set to respectively 1 till
16.
Note: When Local is selected, you can choose channel 1 till channel 8.
When Master is selected, you can choose channel 1 till channel 32.
PROCESS CONTROL
Gain-CH_1 ~
Gain-CH_16
These items allow you to gain the audio for each individual channel in a
range from –60dB to 12 dB in steps of 0.25 dB. –999dB mutes this
channel. Default is 0dB.
Phase-CH_1 ~
Phase-CH_16
These items allow you to gain the audio for each individual channel with
180 degrees. Default is 0 degree.
Stereo-CH_1/2 ~
Stereo-CH_15/16
With these settings you can configure the corresponding channels
(channels 1/2, channels 3/4, channels 5/6, etc.) as being mono channels
(In which case for instance channel 1 and 2 will both contain a mix of
channel 1 + channel 2) or combined stereo channels.

17
Delay_CH_1/2 ~
Delay_CH_15/16
These settings allow you to delay the audio of each pair of channels in a
range of 0 to 1300 ms. In steps of 0.01 ms. Default is 0ms.
IN BUS CONTROL
Override 17/24
If you want to pass processed audio from one quad speed add-on card to
the other (for instance if you want to pass decoded Dolby E audio from
this card to for instance a Loudness Control or Dolby D encoder add-on
card next to this card) you have to use this setting. You can choose to
override input channels 17/24 on the add-on bus of the next card (right
side) with output channels 1 to 8 or pass the master-card audio.
Override 25/32
With this setting you can choose whether you want to override input
channels 25/32 on the add-on bus of the next add-on card (right side)
with output channels 9 to 16 or pass the master-card audio.
VO CONTROL
The DBD handles Voice Over channels. With the following settings you can set how the involved
program out channels should react to a voice over signal and how everything is triggered. The
following graphic gives a visualisation of the settings.
VO_Trigger
With this setting you set how a voice over trigger is generated. Can be set
to off (in which case a voice over is never triggered), GPI_0 (voice over
processing is triggered by GPI contact 0) or Auto (voice over processing
is triggered when the voice over channels reaches the trigger level
volume set with VO_Trglvl). Default is Off.

18
VO_Sel
Here you set a source which contains the voice over channel. Can be set
to Local (physical AES/EBU inputs), Master (audio coming from
master card via add-on) or Decoded_PCM (audio coming from the
Dolby decoder). Default is Local.
VO_Ch
Here you select which channel in the above selected source contains the
voice over content. Default is channel 7.
VO_Scale
With this setting you set a scale in dB with which the program out
channels should be decreased in volume when a voice over is triggered.
Can be between -95dB and 0dB. Default is -60dB.
VO_Trglvl
This setting is used when VO_Trigger is set to auto. You set a
threshold in dBFS between -95 and 0dBFS. When the voice over channel
reaches this threshold, voice over processing is triggered.
VO_Delay
This is the delay in ms (up to 1000 ms) with which the voice over
channel is delayed. This is the time between the trigger and the actual
insertion (see graphic in VO control header). Default is 256ms.
VO_Hold
This is the time between the end of the voice over (audio goes below the
VO_Trgrlvl threshold or GPI_0 is released, depending on what is set
in VO_Trigger) and the start of the voice over release (see graphic in
VO control header). Default is 256ms.
VO_Release
This is the “release” time. The time between the end of the VO hold and
the point where the program out channels are at their full volume level
again (see graphic in VO control header). Default is 256ms.
VO_Rampdown
This is the “ramp down” time. The time between the VO trigger and the
point where the program out channels have reached the volume level set
with VO_scal (see graphic in VO control header). Default is 256ms.
VO_Ch_1 ~
VO_Ch_16
With these settings you set which program out channels should be
affected by VO settings. You can set channels to VO (affected by the
voice over like indicted in the graph), Duck_Only (only ramp down the
program out channel, but don’t mix in the voice over) or No_VO
(channel unaffected by voice over). Default is No_VO for all channels.

OUTPUT CONTROL
Slot1/2 ~ Slot31/32
These menu items are to fill the Quad speed audio bus with the
appropriate outputs. You can fill any of the 16 audio pairs (32 channels
in total) with the audio that is set to Out1/2, Out3/4, etc till
Out15/16. You can also switch the concerning pair to off, making the
concerning audio pair empty.
Meta_BUS
The DEE28 can output the dolby metadata to the ADD-ON bus. This
metadata signal is always put onto slots 25 till 32. When this setting is
switched on, the setting Slot25/26 till Slot31/32 will not be used
anymore. This function must be supported by the master can you send it
to.
DOLBY GENERAL
Mon_out_program
With this setting you select which output program you want to monitor in
the status tab. You can choose any available program (up to 8 depending
on the program configuration: 7.1, 5.1+2, 5.1, 4x2, 3x2, 2+2, 8x1, etc.).
Backup_out12
With the DEE28 you can decide which of the decoder outputs contains
the backup audio channel (set with settings backup,
Dolby_PCM_backup and back_ch). With Backup_out12 set to
on, decoder outputs 1 and 2 will contains the assigned backup channel in
case the back switch is activated.
Backup_out34
With Backup_out34 set to on, decoder outputs 3 and 4 will contain
the assigned backup channels in case the backup switch is activated.
Backup_out56
With Backup_out56 set to on, decoder outputs 5 and 6 will contain
the assigned backup channels in case the backup switch is activated.
Backup_out78
With Backup_out78 set to on, decoder outputs 7 and 8 will contain
the assigned backup channels in case the backup switch is activated.
Downmix
Here you can set the downmix mode of the downmix output of the Dolby
Decoder. Can be Lt/Rt (Left total/right total, a downmix suitable for
decoding with a Dolby Pro Logic upmixer to obtain 5.1 channels again),
Lr/Ro (Left only/right only, a downmix suitable when mono
compatibility is required), or Auto (Lt/Rt or Lo/Ro is chosen dependant
on the whether or not there’s a 5.1 program config or not). Default is
Auto.

20
PCM_metadata
With this setting you decide whether you want to keep generating
metadata in case the Dolby E is lost. Default is off.
PCM_latency
Here you define the delay in case the Dolby signal is lost. Can be set to
SingleFrame (equal to Dolby E decoding) or to minimum.
VIDEO SYNC CONTROL
Dolby E decoders generally require a valid video sync input signal when
operating. This signal must be aligned and matched to the timing and rate
of the incoming Dolby E signal. Many facilities use a Vsync signal as a
reference for timing throughout a larger broadcast chain.
VsyncALIGN
If the Vsync signal is present and properly matched, the DOLBY
DECODER/ENCODER can then attempt to perfect the alignment. This
option (vsyncALIGN) enables latency adjustment of the decoded audio
so that the Dolby E stream is aligned exactly to the Vsync signal. The
latency adjustment amount is up to plus or minus half the guard band
length listed in the following table.
Guard Band Length Frame Rate
360 samples 23.98 Hz
360 samples 24 Hz
192 samples 25 Hz
160 samples 29.97 Hz
160 samples 30 Hz
VsyncINP
Here you set the input for the vsync. Can be either ref1 or ref2.
VsyncENA
If the option (vsyncALIGN) to align a Vsync signal when decoding
Dolby E is set, and the signal is not aligned (within the tolerance
window), the DOLBY DECODER/ENCODER can then attempt to
reconstruct the alignment. This option (VsyncENA) adjusts the latency
of the decoded
audio so that the Vsync signal is aligned exactly to the Dolby E stream.
The amount of latency added for the alignment is limited by the
corresponding video frame length.
