Crystal Vision Introduction
DADA208 User Manual R3.7 322/08/2016
1 Introduction
The DADA208 is a dual channel digital audio distribution amplifier with reclocked
outputs.
It may be configured as a single 1-in/8-out distribution amplifier or as two 1-in/4-out
distribution amplifiers.
DADA208 dual digital audio DA
It supports either 75Ωor 110Ωinputs and selectable 'piggy-back' output modules allow
either 75Ωoutputs (OPAES-75) or 110Ωoutputs (OPAES-110). The position the output
module plugs into is dependent on the rear connector fitted as explained in the Installation
chapter.
There is a choice of eleven rear connectors that range from single slot to quadruple slot to
allow a mix between high packing density and access to all output connections. They also
provide a mix between BNCs for 75Ωconnections or multiway 'D' and DIN41612
connectors for 110Ωconnections.
DADA208 is a very compact board with up to 24 modules fitting in a 4U frame when a
single slot rear connector is used.
The DADA208 has LED and GPI indication of input presence/failure for each channel.

DADA208 User Manual R3.7 422/08/2016
DADA208 reclocked dual digital audio DA
The main features are as follows:
•Dual 1 in 4 out or single 1 in 8 out digital audio distribution amplifier
•Choice of ten rear connectors with variable packing density and either 75Ωor
110Ωconnectors
•GPI/LED input presence indication
•Card edge control
Note:
This manual covers the DADA208. The DADA208N with non re-clocked outputs and the
DADA208D with up to one second of delay are also available.

3Hardware installation
The DADA208 dual channel digital audio distribution amplifier fits into all Crystal
Vision rack frames. All modules can be plugged in and removed while the frame is
powered without damage.
3.1 Selecting rear connectors
When used with a single height rear connector, the Indigo 4 frame will house up to 24
modules, the 2U Indigo or FR2AV frame will house up to 12 modules and dual power
supplies, the 1U Indigo or FR1AV frame will house 6 modules and a single power supply.
The 1U Desk Top Box has a built-in power supply and will house up to 2 modules with a
single height rear connector.
The 4U, 2U and 1U frames have a hinged front panel, which gives access to the PSU and
all modules. The Desk Top Box has a removable front. The universal frame wiring system
allows any of the interface range of modules to be fitted in any position with the use of
removable rear modules.
The following table summarises the rear connectors available.

RM35** 1 1 2x110Ωin/4x110Ωout per channel
Notes: Table shows no of cards per rear connector.
Passive loop-throughs are independent of the amplifier; the module may be removed
without losing the looped-through source.
*The RM03 uses a 25 way 'D' output connector and the RM11 uses a 26 way High
Density 'D' output connector. **The RM35 uses a DIN41612 64 way a+c connector
For details of fitting rear connectors, please refer to the appropriate frame manual.

3.2 Selecting the output module
There are two types of output module, one for 75Ωoutputs (OPAES-75) and one for
110Ωoutputs (OPAES-110). The modules are designed to fit in one of two positions near
the edge connector of the board.
DADA208 dual digital audio DA
The position the output module plugs into is dependent on the rear connector fitted as the
following table shows:
Rear Module Input

Note: Only one piggy-back module should be fitted at any one time.
Silk-screen text for the output module positions may not include later rear connectors
such as the RM09, RM10 and RM21 or RM35.
Fitting the output module
To fit an output module, proceed as follows:
•Offer up the appropriate module to the correct three-header position for the rear
connector in use
•Ensure that the module is component side up
•Press down firmly ensuringthat no pins are bent and that all pins line up with
header sockets

3.4 Selecting single or dual channel mode
The DADA208 may be configured as a single channel (1 x 8) or dual channel (2 x 4)
digital audio distribution amplifier using the board edge switch.
The channel mode is selected by changing the input source for channel 2 using S1 switch
2 as follows:
DADA208 single/dual configuration PL12 Position
4+4 outputs (2-channel mode) CH2 (up)
8 outputs, all from input 1 (1-channel mode) CH1 (down)
3.5 Configuring the second channel input
The second channel input requires that jumper PL5 is placed in accordance with the
following table:
Rear Module PL5 position
RM01, RM02, RM09, RM10, RM16 RM01, RM02, RM16 (top)
RM03, RM11, RM12, RM13, RM21, RM35 RM03, RM11, RM12, RM13 (bottom)
This information is also available in the pin-out tables for each rear connector.
Configuration jumper PL5 can be found near the edge connector of the board.
3.6 Obtaining an extra output in 1-channel mode
When the distribution amplifier is in 1-channel mode with an RM01, RM02 or RM10 rear
connector it is possible to configure the second channel input connection as an output
using PL2 as follows:
