CHAPTER 1: Overview Introduction The MADI.SRC enables real time sample rate conversion of a complete MADI stream. It includes 32 high quality stereo sample rate converters, and supports all source and destination sample rates from 30 kHz to 50 kHz and their multiples, for all MADI formats (48k/96k Frame, 56/64 channels, S/MUX).
The stream is processed in real time and all output channels are phase and sample accurate to each other. Further the MADI.SRC can be used as a decoupling device to connect two asynchronous systems without any loss of audio quality.

Chapter 5: Operating Modes Introduction The MADI.SRC provides 32 stereo sample rate converters resulting in 64 audio channels available for sample rate conversion. As a MADI signal is limited in bandwidth to a maximum of 64 channels at 1 FS, the number of available channels is governed by the chosen scaling factor: •...
Depending on the combination of input and output scaling factor not all input channels might be available at the target (output) sample rate. Example '1 FS to 4 FS': 64 channels @ 1 FS > 16 channels @ 4 FS page 30 of 44 MADI.SRC Manual - Version 2.0...
Channel mapping - if both inputs are available and input 2 is fed only, the mapping of the output channels remains unaffected. Example '2 FS to 1 FS': channels 01-32 are empty (input 1) and channels 33-64 active (input 2). MADI.SRC Manual - Version 2.0 page 31 of 44...
Normally, the scaling factor of the base sample rate is defi ned manually for input and output from the SRC controls. However, the MADI.SRC offers an option to switch the output scaling factor automatically – Auto Clock Range Select (ACRS).
