  • The RB-DDA22 is a multiple input and multiple output digital audio distribution amplifier designed to accept one of 5 different digital inputs, amplify it and output this to 22 digital audio outputs in 5 different audio formats.

    The RB-DDA22 is a multiple input and multiple output digital audio distribution amplifier designed to accept one of 5 different digital inputs, amplify it and output this to 22 digital audio outputs in 5 different audio formats.
     
    It accepts signals with sample rates in the range 32kHz to 192kHz and distributes them without sample rate conversion.
     
    There are 5 inputs, one each of balanced AES/EBU on an XLR socket, unbalanced AES/EBU on BNC, balanced AES/EBU on an RJ45 socket, unbalanced S/PDIF on a phono socket and a TOSlink optical connection.
     
    An illuminated front panel input select push button is used to choose one of the 5 inputs, or to select the Auto Mode. In Auto Mode the unit interrogates each of the inputs in turn until it finds a lock. The select button flashes to indicate loss of lock and the tri-colour input LEDs around the push button indicate signal presence.
     
    When an input is selected, it is copied to all of the available outputs. There are 5 sets of digital audio outputs consisting of: 6 x balanced AES/EBU on XLR plugs, 6 x professional unbalanced AES/EBU on BNCs, 6 x balanced AES/EBU on RJ45 sockets, 2 x unbalanced S/PDIF on phono sockets and 2 x TOSlink optical outputs, giving 22 outputs in total, 12 balanced and 10 unbalanced.
     
    The RJ45 input and output connections use the StudioHub+TM * wiring standard for the balanced AES/EBU connections.
    Note: The BNC outputs can be converted to S/PDIF outputs using a simple locking connector, available separately, giving an additional 6 x S/PDIF outputs, if required.
