Hi,

I am using a brand new 52X with abyss 2nd stage regulator, and noticed that during exhalation I can hear the first stage opening for short periods, thus while exhaling some air also inflows simultaneously. On the surface this causes the 2nd stage membrane an annoying/ugly reverberation noise.

Is it a normal behavior (haven't used a diaphragm regulator for eons :p ), or something that can be simply corrected (e.g. a small orifice adjustment for cracking pressure) ?
