A fluidic gainblock for amplifying AC pressure signals having an additional element known as a "T" junction added to the interconnection region between the stages of an LPA gainblock. Where normally there would be direct coupling between LPA's in a staged gainblock, there is now provided a path for the interstage flow noise and DC bias to exit prior to entering the next stage. This gainblock now allows as many stages to be added as needed in a gainblock as the elimination of the DC bias prevents the saturation of the gainblock. Interconnection flow noise is now minimized or eliminated completely and only the pressure signal is allowed to enter the next stage via the perpendicular branch of the "T" junction.
