1. General
The flashlink ® DA-AA is a dual 4 output analogue Audio Distributor. The DA-AA can be configured as
either a dual 1x4 or a single 1x8 amplifier. The latter configuration is made by connecting the inputs in
parallel or using DIP switch on PCB. The Distribution amplifier has differential inputs and differential
outputs. Overall gain can be set by DIP switches or by potentiometer for high precision gain setting. The
gain range setting is from -12 to +12 dB. The input signal can be mixed to the other channel using a DIP
switch. The Distribution Amplifier handles analogue audio signals from 20Hz to 80 kHz. The DA-AA is
designed for all audio distribution purposes in studio, duplication and Broadcast applications.

4.1 Mounting the connector module.
The details of how the connector module is mounted, is found in the user manual for the sub-rack frame
FR-2RU-10-2.
This manual is also available from our web site: http://www.network-electronics.com/
5. Module status
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional).
2. LEDs at the front of the sub-rack.
LED’s are mounted on the module itself, whereas the GYDA System Controller is a separate module
giving detailed information on the card status. The function of the LEDs are described in sections 5.1.
The GYDA controller is described in a separate user manual.

5.1 Front Panel - Status Monitoring
The status of the module can be easily monitored visually by the LED’s at the front of the module. The
LED’s are visible through the front panel. The LED on top tells if the DA-AA is ok or not (green LED
means ok – red is alarm). The second LED gives the input signal status.
The DA-AA has 2 LEDs each showing a status corresponding.
Diode \ state Red LED Yellow LED Green LED No light
Status Module is faulty
Module is OK Module power is OK Module has no power
Input No signal present Signal present
6. Interface with GYDA and RS-422 command set
All commands follow the flashlink protocol and can be used for direct control access to the modul. The
control system can either be a GYDA-SC or a third-party control system with integrated flashlink
protocol. The module can also be manually controlled with a VT100 compatible terminal program.
The protocol can be found on our web page; http://www.network-electronics.com

Materials declaration and recycling information
Materials declaration
For product sold into China after 1st March 2007, we comply with the “Administrative Measure on the
Control of Pollution by Electronic Information Products”. In the first stage of this legislation, content of
six hazardous materials has to be declared. The table below shows the required information.

O: Indicates that this toxic or hazardous substance contained in all of the homogeneous materials for
this part is below the limit requirement in SJ/T11363-2006.
X: Indicates that this toxic or hazardous substance contained in at least one of the homogeneous
materials used for this part is above the limit requirement in SJ/T11363-2006.
Environmentally-friendly use period
The manual must include a statement of the “environmentally friendly use period”. This is defined as the
period of normal use before any hazardous material is released to the environment. The guidance on how
the EFUP is to be calculated is not finalised at the time of writing. See
http://www.aeanet.org/GovernmentAffairs/qfLeOpAaZXaMxqGjSFbEidSdPNtpT.pdf for an unofficial
translation of the draft guidance. For our own products, Network Electronics has chosen to use the 50
year figure recommended in this draft regulation.
Network Electronics suggests the following statement on An “Environmentally Friendly Use Period”
(EFUP) setting out normal use:
EFUP is the time the product can be used in normal service life without leaking the hazardous materials. We expect the normal
use environment to be in an equipment room at controlled temperature range (0ºC - 40ºC) with moderate humidity (< 90%, non-
condensing) and clean air, not subject to vibration or shock.
Further, a statement on any hazardous material content, for instance, for a product that uses some tin/lead
solders:
Where a product contains potentially hazardous materials, this is indicated on the product by the appropriate symbol containing
the EFUP. The hazardous material content is limited to lead (Pb) in some solders. This is extremely stable in normal use and the
EFUP is taken as 50 years, by comparison with the EFUP given for Digital Exchange/Switching Platform in equipment in
Appendix A of “General Rule of Environment-Friendly Use Period of Electronic Information Products”. This is indicated by the
product marking:

It is assumed that while the product is in normal use, any batteries associated with real-time clocks or battery-backed RAM will
be replaced at the regular intervals.
The EFUP relates only to the environmental impact of the product in normal use, it does not imply that the product will
continue to be supported for 50 years.
Recycling information
Network Electronics provides assistance to customers and recyclers through our web site
http://www.network-electronics.com.Please contact Network Electronics’ Customer Support for
assistance with recycling if this site does not show the information you require.
Where it is not possible to return the product to Network Electronics or its agents for recycling, the
following general information may be of assistance:
Before attempting disassembly, ensure the product is completely disconnected from power and signal
connections.
All major parts are marked or labelled to show their material content.
Depending on the date of manufacture, this product may contain lead in solder.
Some circuit boards may contain battery-backed memory devices.
