Introduction The RAKK USB to SPDIF Converter is based on the MiniDSP Streamer, which we have adapted for use with the RAKK dac. The USB to SPDIF Converter is intended to be used in conjunction with the RAKK dac Mark III digital board or other DAC that has an SPDIF input. For the best performance possible, the SPDIF interface must be isolated from the circuitry in the DAC that it is attached to.
Assembly Instructions ———————————————————————————— The USB to SPDIF converter digital board is provided completely assembled. However, a transformer must be installed on the RAKK dac. Install a Lundahl LL1572 in the location on the RAKK dac that you have chosen to support the USB to SPDIF interface.
Installation Instructions ———————————————————————————— The RAKK USB to SPDIF board is intended to be mounted to the back panel of the enclosure. These instructions assume that the USB to SPDIF board will be used with the RAKK dac Mark III. The connection between the RAKK dac and the USB to SPDIF board has a plus and a minus (+/-) polarity.

Refer to the diagram below for connections between the RAKK USB to SPDIF board and its power supply. ———————————————————————————— 5. Install the red/black twisted pair. Solder the red wire to pad 10 and the associated black wire to pad 7 on the USB to I2S board. ————————————————————————————...
9. Refer to the Grounding section below and, if needed, install a wire between the (–) pad of the power supply and the chassis at the point where the green-wire safety ground is connected to the chassis. ———————————————————————————— 10. Mount the boards in their locations and secure them in place. ————————————————————————————...
