Hello
@mihi_fuchs
Finally, I could pull together the final assembly and my very first build, another 9 to go.
Yet, there are some details which I must clarify and some little bit of noise [I have a slight doubt if it’s ground missing on the capsule grill].
| CAPSULE + Connection |
1. Just need to clarify if each side of the capsule should have a
yellow wire [diaphragm wire] and
black wire [backplate] connected to each side respectively. Is that correct?
If so, does each respective side of the capsule go to each PCB accordingly [front and back]?
2. Is there a problem with some sort of overlap of a bit of the washer to the immediate next opposite backplate?
| MIC BODY |
I’m using the Aurycle mic body to do this build. It comes with low cut and -10db pad switches on which I had to desolder the wires since I will use these options in the software.
Yet I encountered this white cable which I doubt is GROUND for the capsule. If so, should I solder to GND on the top of the PCB and jumper between both PCB’S?
| LOW PASS FILTER |
Just to clarify in another word…In case you use a removable C17 via socket, you don’t need to do anything about J3, is that correct? Essentially J3 is an “on and off switcher” if you have a
permanent C17 cap, correct?
| PCB’s Screw’s |
This build doesn’t right fit to this mic body frame within the mounting holes. I have put zippers for the testing, but I need a permanent solution such as M screws with washers and nuts. Yet looks like I need M1.2 screws with about 15-20mm long but I can’t find anywhere.
Should I drill a bigger hole to fit another kind of screw so I could use screws such as M1.6x20mm?
| JFET |
To JFET match the only thing that mostly matters is
Idss ?
I’m having some inconsistent readings. Should I look always for the first number that comes up on the multimeter as the final reading?
| PROBLEMS and CLARIFICATIONS |
I have finished 2 mics before making sure about my question.
Both have the same problem.
1. For final calibration on RV1 onboard potentiometer, the PCB for the back of the capsule whatever I do doesn’t change the SCT_T – GND value, looks like it gets maxed out and starts clicking when turning the screw. What is wrong?
2. I have a Slight High pitch sound, but that vanishes when my hand goes on the capsule grill. Is anything to do with the screws on the frame? the white wire as referred above?
3. What is this 51g hole for? Alternative connection for the capsule diaphragm wire?
Thanks in advance,
Best
