  • Page 26: Chapter 4: Operating Modes

    Chapter 4: Operating Modes Chapter 4: operating Modes introduction The MADI.SRC provides two operating modes: • In Normal Mode one input is used and both outputs operate in parallel. • In Split Mode both inputs and outputs are combined in order to take optimal advantage of the SRCs available.

  • Page 27: Normal Mode

    In Normal Mode only one MADI input can be used at a time and both outputs transmit identical signals in parallel. The MADI.SRC automatically detects the sample rate (base rate) and frame format of the MADI input signal. The detected base rate may then be multiplied by a scaling factor of 1, 2 or 4 resulting in the following sample rates: • 44.1 kHz (1 FS), 88.2 kHz (2 FS), 176.4 kHz (4 FS)

  • Page 28: Split Mode

    2 channels is unaffected (e.g. 2 FS to 1 FS: at output 2, channels 01-32 are empty (Input 1) and channels 33-64 active (Input 2). page 28 of 40 MADI.SRC Manual - Version 1.4 © 2014 DirectOut GmbH...

  • Page 29: Auto Clock Range Select (Acrs)

    Normally, the scaling factor of the base sample rate (1 FS, 2 FS or 4 FS) is defined manually for input and output from the SRC con- trols. However, the MADI.SRC offers an option to switch the output scaling factor automatically – Auto Clock Range Select (ACRS).
