I may be interested in this. Did your amp come with any info? I have found the board being sold without an enclosure and the blurb says this :-
This high-precision 256-stage volume controller is ideal for the design of passive or active preamplifiers in XLR symmetric or classical RCA asymmetric design.

Strengths:
Perfect channel balance
Analog bridge meter supplied
Digital Analogue Controller ADC0804
Same linear quality as a switched resistance potentiometer
Integrated circuit power supply

It says that the balanced IN & OUT uses the ADC0804 which uses a 256 stage volume controller. I wonder how this works with the passive volume control. Have you used it balanced?
