The SRC-128 add-on module adds the capability of asynchronous sample rate conversion to your multiverter. Designed as internal add-on module, it leaves the "Extension" port available to other break-out boxes. (Note: The module is called "SRC" in this manual for clarity). It features highest analog performance (THD+N -134dB typ.), bi-directional
conversion for total up to 128 channels (e.g. 128x0 uni-directional, or 64x64 bidirectional) between any interfaces supported by the multiverter. With the SRC installed, the multiverter accepts signals from two different clock domains (A and B). Each input and/or output can be assigned to run either on clock A or clock B. When routings are established between inputs and outputs on different clocks, the signals are automatically routed through the SRC to match the sample rate of the target.
