Unless you want a mechanically coupled motor driven potentiometer, better a
bunch of them, there is no solution with discrete components. I have built a
similar VCA array, but only single ended with the SSM2164 quad variable
transimpedance amp, which has a dB-linear control input(+24dB...-120dB).
There are other solutions with slightly higher quality but at multiple cost
and with the need of incorporating a digital controller chip. If you are
interested, please drop me a mail
