Re: Duo-Art Plays Too Loud
By Spencer Chase

Robbie Rhodes writes about the 3 bar linkage in Duo-Art grands and the non-linear effect on knife valve movement. Does anyone know the effect of adjustment of the simpler upright duo-art linkage and the correct starting position? I have played around with it trying to compress and expand the dynamic range and figured I would wear things out before I figured it out.

The service manual warns to not adjust the leather nuts on the pull-down rod as it is set at the factory. This plus readjustment of the zero setting screw would change the dynamic curve. Unfortunately the factory is no longer available to consult for the original setting or for advice on the changing of that setting.
