The
phantom power is on for the board and, once again, the mic works with a different cable and same board. The cable is wired
shield to pin 1, blue to pin 2, and white to pin 3. This is right, correct? There are two whites and two blues, so you simply twist the
wire together and solder both of them, right?
Hiya,
It does not matter which color goes to which pin as long as it is the same on both ends.
Few things to check out and report back...
Have you tried different cables on the same
mixer CHANNEL, and vica versa (move the problem cable to another
channel)? This will eliminate the
channel as a problem for delivering phantom. Sounds pretty basic and you may have done this--but I have to ask, as some folks willl test another mic cable and problem on another
channel and it works fine, and still have problems on the original
channel without testing the
channel they want to use.
Another thing to check--take a Volt/
OHM meter and check that you are getting 48V DC
voltage passing
thru the cable... (or whatever your phantom
voltage output is at the input source--phantom
power can vary in range from
console to console--but the
voltage should be the same at the
channel and at the end of the cable.)
Meter this at the
channel input, then connect the cable in question and then
meter the
voltage again at the end of the cable. If you get less or you have different
voltage or leaks on the
connector chassis--somewhere you have a drain or short in the cable.
Pin 1---Ok is this a open braided
shield? In other words--exposed in a loose weave around the rest of the cable? Occasionally with QUAD star--you run into the issue where the
ground braid does not make good contact or is frayed too much in making it into a "
wire"--or only partial contact is made. Depending on the source of your
phantom power, this can
effect its performance. (even tho Phantom typically uses pins 2 and 3--it also rely's on the
ground to be intact completely and the
voltage supplied is relative to the
ground). Its not common as a problem, but can happen on home made cables with quad star with
phantom power.
My feeling still is to check your connections--make sure each
wire is set to the same pin on each side (a cable tester or
continuity tester will help with this). Also check that each pin does not cross to other pins or the chassis of the
connector.. Its very easy with Quad star to twist the wrong pairs together or not join the two wires completely into a single pair or for half of the piar to break off one cable etc--and then you have problems...or
wire pairs to the wrong pin from the other end or even mix up pairs entirely (yes I've seen red and black get twisted together--and folks swear they thought they did both red and both black)... It happens.....
