Question about Earthworks QTC30 Omni Professional Microphone

1 Answer

SR71 I have a pair of SR71 and love them. Recently, one of them has developed some extraneous noise. After experimenting with it, I finally isolated the problem to the XLR connector. When the extraneous nosie happens ( intermittenly), and I wiggle the connector, the noise would go away. I have tried different cables to ensure its not the problem with the cables. Since there is currently no distributor of Earthwork product in Hong Kong (where I live), I would like to try to fix it myself. I am a electronic engineer. I think there is probably some loose connection at the XLR connector. The question I want to ask is how to dismantle the microphone.

    Unfortunately, I could not take it apart by twisting the bottom part of the mic. It almost seems to be glued together. There is no screw on the bottom part (the XLR connector opening) that I can see either. So I am still trying.
    Thanks anyway for your suggestions.

I am not sure about this model of mic but it could be as easy as twisting off the bottom. There could also be a screw near the XLR jack that has to be removed, or tightened. Some mics have the XLR jack glued in pretty tightly. I am giving you suggestions based on other mics, I haven't touched a SR71. Hope that helps! Baze

Why There are not new aircrafts ?

There are plenty of new aircraft of all sorts developed all the time. Not sure why you'd think there weren't. Even given the date you gave, there are aircraft newer than that but old enough for *their* replacements to be entering service (multiple F-15, F-16, F/A-18 variants, F-22, F-35, B-2....)

No,the printer will not run without PCU's installed.The only way unfortunately on this model is to check all gears visually.Most likely bad gears either in one of the PCU's or in the fusing unit.
