Adjusting Speaker Volume With I Dial?

[Elliot3141]

I have connected 2 KRK Rokit 5 G3 to directly to my monitor by a mini jack split into mono jack and was wondering if there was a way of doing this so i can adjust the volume with a knob instead of accessing the back of the speakers, monitor or windows volume

thanks,

Elliot
