  • Just as every AxC card within the Audio ToolBox range, the AxC-ADSP can equally be used in AVBx3 or AVBx7 platforms. Using one slot of either ToolBox, the AxC-ADSP can acts as an Asynchronous Sample Rate Conversion (ASRC) card or as a Digital Signal Processing card. ASRC enables to exchange audio channels between an AxC-Card working with a different frequency or with another clock domain than the other cards.


    • An AxC-ADSP card enables to exchange 128 IO channels at 2 different frequencies. It is an ASRC interface between one of the AxC audio network or digital interface card and any other Audio/Network AxC cards of an AVBx3 or AVBx7.
    • Up to 3xAxC-ADSP cards can be used in an AVBx7. They manage audio exchanges of up to 4x 128 IO channels with up to 4x different Audio Clock frequencies domain in only a 2U 19” frame. Each clock domain can be connected via an AxC audio network (Dante, AES67, CobraNet, EtherSound) or an AxC digital interfaces, (Madi, AES/EBU, ADAT).
