1 Product overview
The Flashlink DA-VAEQ-6 is an analog video distribution amplifier module with input
equalizer, gain, black level clamping and passive input loop providing high performance
media distribution for analog standard definition video signals . The input signal can be
equalized for up to 300m of cable and is distributed to 6 equivalent outputs. Both
equalization and gain can be controlled on potentiometers accessed at the front of the card.
The input is switchable to high impedance for multi drop purposes. Outputs have 75 ohms
impedance. A signal detector will indicate if signal is present (LED and GPI).
The DA-VAEQ-6 is designed for all standard definition analog video distribution purposes in
studio, duplication and broadcast applications.
The DA-VAEQ-6 is well suited for distribution of AES-3id signals (75 ohms unbalanced AES
over coaxial cables).

3 Connections
The DA-VAEQ-6 has a dedicated connector module: DA-VA-C2. This module is mounted at
the rear of the sub-rack. The module is shown in figure 2.
Figure 2: Overview of the DA-VA-C2 connector module (default backplane).
The electrical input signal is connected to the two IN BNCs, and the electrical outputs are
connected to the O1 to O6 BNC’s. Please note that all 6 outputs are non-inverted. On the
back side of this board, there is a DIP switch (see figure 5 in chapter 4.4) to set the
termination. If switch 1 is on, there is a 75 ohms termination. DIP switch 2 is not used.
3.1 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.

4 Operation
The equalization and gain can be controlled from two potentiometers.
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional)
2. GPI at the connector module
3. LED’s at the front edge of the module
Of these three, the GPI and the 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 functions of the GPI and the LED are described in sections 5.1 and 5.2. The
GYDA controller is described in a separate user manual.
4.1 GPI ALARM – Module Status Outputs
Only available when using the standard –C1 backplane
These outputs can be used for wiring up alarms for third party control systems. The GPI
outputs are open collector output, sinking to ground when an alarm is triggered. The GPI
connector is shown in figure 4.
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V

4.2 Front Panel - Status Monitoring and Signal Detection
The status of the module can be monitored visually at the front of the front of the module.
The DA-VAEQ-6 has one LED showing the status. The hardware revision 2 of the DA-
VAEQ-6 has also a built in detector for signal monitoring. When signal is present, LED is
green, otherwise it will be red. The LEDs are described in the following table:
