1 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 EVS Broadcast Equipment SA Website at
http://www.evs.com 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 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 settin
g
s and status information.
Remote Control
Capabilities
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: “EVS CORTEX” SOFTWARE WILL
INCREASE SYSTEM FLEXIBILITY OF ONE OR MORE
SYNAPSE FRAMES
Although not required to use EVS Cortex with a Synapse frame, you are
strongly advised to use a remote personal computer or laptop PC with
EVS Cortex installed as this increases the ease of use and understanding
of the modules.

2 Unpacking and Placement
Unpacking The EVS 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

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 DIO88 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.
Changing
settings and
parameters
The front panel controls or EVS Cortex can be used to change settings.
An overview of the settings can be found in chapter 5, 6 and 7 of this
manual.

EVS Cortex EVS 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.
EVS Cortex has access to data contained within the Synapse module and
displays it on a GUI. The software has an intuitive structure following
that of the module that it is controlling.
For operation of EVS Cortex, please refer to the EVS Cortex help files
(press F1 in any window).

4 The DIO88 Card
Introduction The Synapse quad speed audio bus enables up to 32 channels being
transported from Master Card to ADD-ON card and simultaneously 32
channels from ADD-ON card(s) to Master Card.
The DIO88 can be used in 3 modes. The card only works as an ADD-ON
card and can therefore not be used without a Master card. Mode 1 makes
the card a universal 4 AES/EBU in and 4 AES/EBU output card. This
gives the user a function to insert and extract up to 8 mono channels from
any Quad Speed compatible Master card.
Mode 2 turns the DIO88 into an 8 AES/EBU insert card, providing the
insertion of up to 16 mono channels into any Quad Speed compatible
Master card.
Mode 3 is used to extract 8 AES/EBU (16 mono audio) channels from a
Quad Speed compatible Master Card.
Triple mode quad speed audio ADD-ON card (Cortex
controllable, no reboot required)
Mode 1: 4x AES/EBU in and 4x AESEBU out.
Mode 2: 8x AES/EBU in.
Mode 3: 8x AESEBU out.
Full audio swapping of all input channels allow for a selection of
any AES/EBU input or any of the 32 channel bus input to be
selected
16 channels of audio gain
16 channels of audio phase reversal
8x 2channel audio delay up to 1300ms
8 stereo>mono switches
16x 2 channel audio insertion into 32 channel Quad speed audio
bus (allows for duplicates)
Full control and status monitoring through the front panel of the
SFR04/SFR08/SFR18 frame and the Ethernet port (ACP)
Applications 16 channel insertion to QUAD SPEED audio Master card
16 channel extraction from QUAD SPEED audio Master card

5 Settings Menu
Introduction The settings menu displays the current state of each setting within the
DIO88 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 EVS Cortex.
Please refer to chapter 3 for information on the Synapse front panel
control and EVS 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.
In_Out In_Out determines how the synapse bus inputs and outputs work.
There’s 3 modes:
■4In-4Out: 4 AES/EBU input and 4 AES/EBU outputs
■8In: 8 AES/EBU input and no outputs
■8Out: no inputs and 8 AES/EBU outputs
Refer to the block schematics for more details on the difference modes.
INPUT CONTROL
Sel_Ch1 ~ Sel_Ch16 With these settings you select which audio source you want to use for
process channel 1 till channel 16. You can choose either Local audio
(using the card’s own AES/EBU inputs) or audio coming from the
Master card via de ADD-ON bus.
Note: when the card is set to 8Out mode (in the In_Out setting) the
local inputs aren’t used and therefore can’t be selected here.
Ch_1 ~ Ch_16 With these settings you select the actual source channel in the above
selected source.
Note: When Local is selected, you can choose channel 1 till channel 16.
When Master is selected,
y
ou can choose channel 1 till channel 32.

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.
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 0to 1300 ms. In steps of 0.01 ms. Default is 0ms.

7 Events Menu
Introduction An event is a special message that is generated on the card
asynchronously. This means that it is not the response to a request to the
card, but a spontaneous messa
g
e.
What is the Goal of
an event? The goal of events is to inform the environment about a changing
condition on the card. A message may be broadcast to mark the change in
status. The message is volatile and cannot be retrieved from the system
after it has been broadcast. There are several means by which the message
can be filtered.
DIO88 Events The events reported by the DIO88 are as follows;
Announcements Announcements is not an event. This item is only used for switching
the announcement of status chan
g
es on/off. 0=off, other =o
n
Audio-Data Error in Audio Data can be selected between 0 .. 255. 0= no
event, 1..255 are the priority setting. In case of a Dolby data ERROR an
Event will be generated at the priority, or the audio carrier is falling away,
or audio data is in the range of 0 dBFS and -1 dBFS, or the Encoder status
is in error.
Reference Reference can be selected between 0 .. 255. 0= no event, 1..255 are the
priority setting. If the reference is lost an Event will be generated at the
priorit
y
.
What information is
available in an
event?
The message consists of the following items;
1) A message string to show what has happened in text, for example:
“INP_LOSS”, “REF_LOSS”, “INP_RETURN”.
2) A tag that also shows what happens, but with a predefined number:
e.g. 1 (= loss of input), 2 (= loss of reference), 129(= 1+128 = return of
input). For a list of these predefined tags see the table on the next page.
3) A priority that marks the importance of an event. This value is defined
by the user and can have any value between 1 and 255, or 0 when
disabled.
4) A slot number of the source of this event.
The Message String The message string is defined in the card and is therefore fixed. It may be

EVS Broadcast E
q
ui
p
ment SA
15
used in controlling software like Synapse Set-up to show the event.
The Tag The tag is also defined in the card. The tag has a fixed meaning. When
controlling or monitoring software should make decisions based on events,
it is easier to use the tag instead of interpreting a string. The first
implementation is the tag controlled switch in the GPI16.
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 (80hex) (e.g.
129 (81hex) for Return of Input).
Defining Tags The tags defined for the DIO88 are:

The Priority The priority is a user-defined value. The higher the priority of the alarm,
the higher this value. Setting the priority to Zero disables the
announcement of this alarm. Alarms with priorities equal or higher than
the Error Threshold setting of the RRC/RRS will cause the Error LED on
