1 Product overview
The Flashlink DA-VA is an analog video distribution amplifier module with passive input
loop providing high performance media distribution for analog signals from DC to 200
MHz. The module also complies with the SMPTE 259 M specification for SDI signals.
The input signal is distributed to 6 equivalent outputs. The input is switch able 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-VA is designed for all distribution purposes in studio, duplication and broadcast
applications.
The DA-VA is well suited for distribution of AES-3id signals (75 ohms unbalanced AES
over coaxial cables).
DA-VA comes with a passive input loop with the default -C2 backplane (Default since
November 2011).
