        For outdoor ambience there is no equal. Used with a good recorder, this mic displays an extremely low noise floor and picks up everything. I mean EVERYTHING. Superb atmospheric sound. I cannot recommend it highly enough.

        • Q:

          I own a AT825 (similar model, according to the website)
          I was wondering if I could use it outdoors, around 0 to -20 celcius, and if it could take humidity levels (I'd like to know the extremes of the mics for the winter temperatures and humidity levels!)

        • Q:

          What is the diameter of the shaft?

          I have a Sony PXW-X70 that has a shotgun microphone holder with rubberized nubs. The holder's diameter is approximately 15/16 inch or 25 mm. What is the diameter of the BP4025 shaft? Is it possible to use (perhaps with an adapter) in shotgun mic holders on pro-level camcorders? Thank you!

            Answering my own question; I found the specification later in one of the support documents (PDF) for this item. The body/shaft has a diameter of 21mm.

          about Audio Technica BP4025 output

          How do i connect the output of Audio Technica BP4025 with my two track recorder?
          and do i need to link the inputs, for example with sound devices 702 they have an option to link stereo or MS, in that way fader 01 becomes the level control and 02 as pan control?

          • A:

            The mic has a left and right output cable adapter so you plug into input 1 left and input 2 right. Yes with a SD 702 recorder you should set inputs 1 and 2 to Link so input 1 knob is gain and input 2 knob is pan.

          • A:

            Thank you for your inquiry. The BP4025 is an XY stereo microphone (left and right) and not a mid side mic (cardioid and figure of eight. The stereo image is fixed. Your options for a 2 track recorder would be left and right channels, where you could adjust the volume and the pan of each channel.
