RE: Preamp Retrofit with Motorized Volume Control

My friend Kevin Carter over at K&K Audio had a customer who wanted him to design a preamp that he could market. He wanted remote volume control as a feature and wanted a stepped attenuator instead of a pot. Kevin had Khozmo Attenuator make up one of their attenuators with a DC servo motor. Then the guy flaked out and canceled the project. Kevin sold me the unit and provided the micro processor control board. My line stage already had remote controlled volume via a motorized Alps pot.,so tapping into the volume up/down data signal and directing it to the PIC controller was easy in my case.

Kevin has some time and money invested in this. He might be willing to sell a control board if you contact him.
