Thank you for the help.
I tried to buy some flux at three different places here locally, but none o=
f them was selling flux. Two of them replied that "it's flux in the solderi=
ng thread, so you don't need it". I told them that I wanted to buy it anywa=
y, but they didn't sell it. I probably have to buy it from internet.
Now i'm wondering about another thing.
I got a 5m cable that came along with my BP4025 stereo mic. I have always t=
hough that it was really sensitive to pick up my cellphone signals. And I a=
lso needed a shorter cable in some situations so I opened it up to see how =
it was soldered so I could do it the same way with the cable and neutrik co=
nnectors I bought and also see why it was so sensitive to celllphone signal=
s.
It's a 5-pin female XLR to two 3-pin male XLR cable and it's two cables tha=
t is stuck together.
One thing I noticed is that the shield that is soldered to the pin 1 on the=
connectors is then "bridged" to the XLR's earth/shield on the edge of the =
XLR connector. Does that make it use recorder as the earth/shield? Is it go=
od or bad to do it like that? Does the cable get more or less sensitive to =
cellphone signals?
I don't know if you (or maybe Jez?) can reply on this problem.
I have two hydrophone mic's from Jez. They have 6.3mm TR connectors.
They work fine if I connect them to channel 5 and 6 on my Tascam DR-680 rec=
order, but if I connect them to channel 1-4 there is a strong annoying sign=
al. The difference is that the first 4 channels have combined XLR/TR(S) con=
nectors.
I wanted to try and record under water with 192kHz out of curiosity and th=
at only works with channel 1-2. Unfortunately I can't use those channels si=
nce there is that "signal". Is this because it's TR and not TRS connectors =
on the mic cables? Should I buy TRS connectors and solder them in a special=
way? Maybe use 3-pin XLR?
Can my recorder be broken even if using XLR connectors works fine in the sa=
me channels?
I hope you understand at least some of my questions and have time to reply.=
