I am wiring up a set of these for someone and just wanted to double check. i was searching the forum and found a few references to wiring the B3's to a single miniplug but no reference to wiring them to mini xlrs. Obviously the ground would be pin 1, now would the red go to pin 2 and black to pin 3 or are they like the at853's where when they are wired 3 wire the red wire is pin 3 and the yellow(signal) is pin 2 but when put on the miniplug the yellow is grounded and the red is the signal, does that make sense.
I'm not sure but I think many (or at least the pig tail version) of the B3's are 2 wire systems
but can also be ordered for mini XLR termination - I think?
some one else may have more info
paging Richard!
Ok if they arrive 2 wire would i bridge the 1 and 3 pin on the mini xlr?
that sounds reasonable
but Richard aka illconditioned would know better than anyone
hopefully he will reply here soon.

So after wiring these up(they are the 3 wire version) we are having a lack of bass response. I wired them pin 1- shield, pin 2- red, pin 3- black to the mini xlr's. I have looked through the forums but there are only references to wiring them to miniplug. Do i need to put a resistor in there or maybe switch the red and black wires? I am also asking because i don't have any gear around to "test" the sound once wired.
Yes, try swapping the wire. Pin 3 on AT is usually power (+5V or so). Pin 2 is audio output, Pin 1 is ground.

thanks guys, so you see no reason for any resistor's on these. These are being powered by a tinybox by the way Jon. And according to the countryman website the red is the signal and lots of the wiring options have a resistor in there.
Try a 4.7k resistor.

Try a 4.7k resistor.
Across 1 and 3 pin and leaving red as 2?

Red to pin 3,
Black to pin 2,
Shield to pin 1.
The 4.7k resistor between pins 2 and 1.

Thanks Richard, thats pretty much how the AT's wire up with resistors as well, also do you think a 2.2k resistor would be fine?
If you've got enough voltage (5v or more), I think 4.7k is better (less distortion).
If you're running on lower voltage (2-3v from plug in power) then 2.2k or even 2.0k is a better bet.
Note: I've had distortion with a 2.0k resistor, very loud show. PA is likely overpowered for the room it is in. But this is only once in many different situations.

Don't add the resistor in this case, the customer's tinybox already has DC termination on the signal pin ;)
ok so i wil ljust swap wires then
