Clockworks' AppNote002 describes how to use MiniDSP's MCHStreamer to create a USB to A2B adapter with Clockworks AB0108 Kit.
A custom cable is needed to connect the MCHStreamer's 2mm 12 pin connector to the AB0108's .1" 12 pin connector. The AppNote describes how to make this cable with readily available parts.
As a service to customers Clockworks can also provide these cables when purchased with the AB0108 kit. Note that the shells are not keyed, and may or may not have the actual pin 1 marked as expected. See the AppNote for details.
These cables are built to order and may have 5-10 day lead time depending on parts availability.
