Combo Input

 

 

 

 

 

The combo input has interfaces for external analog line inputs, the RAKK dac, and a volume control. It provides isolation as well as differential conversion for unbalanced inputs. The kit may be ordered with components for either or both the RAKK dac and line inputs.  You supply your own 50K volume control. The DACT switched attenuator would be a good choice.

For further information on the use of the combo input together with the active output, refer to the Active Output Article

Here is the schematic diagram of the combo input board.
