    i agree with the other reviewer :)


    i can't say it's 'the best mic out there' as i don't have the luxury of comparing esoteric options.. but combined with my FET modded marantz recorder, i have been more than pleased with the finesse and feathery detail this mic is able to p/u, and a robust low end response as well. really fantastic, wide stereo image... i wouldn't use it to record a band in a small room, too much detail (very little rejection), but for immersive ambience it's lovely.

    Superb mic for outdoor ambience


    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 & A

    Would this mic work well on a camcorder for recording a live band in nightclubs?


    Yes it can. You may find helpful information on this topic here:


    What is the self-noise value for this microphone?


    The self noise is 14dB.


    Is the BP4025 available with a short cable such as the 0,61m (24") cable that is sold with the BP4029?

    Kris Kelvin

    Thank you for your inquiry. Another cable is not available.


    Where can I get a replacement for the cable that comes with it (5-pin XLRF-type connector at microphone end, two 3-pin XLRM-type connectors at output end.


    Thank you for your inquiry. Please contact our parts department at 330-686-2600 option 4. They can help with this.


    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!)


    To receive an answer to your question, please contact the Audio-Technica United States (ATUS) Audio Solutions Team at: Please include the specific model number for your product for accurate information. Thanks!


    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?


    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.


    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.
