Very Satisfied

By Garry

I bought the mic for field recordings to make ambient backgrounds. It does the job well. It is not at all hyped, which is a most useful character in a mic to be used for this purpose. Neither is it noisy, The stereo separation is decent. If I lost this one, I would buy another.

Very nice response, low noise

I use this for ambient recordings - I'm usually recording as part of gathering material for video, and so I have enough gear without a multiple-mic stereo setup. This offers a pleasing stereo image, low noise for getting quieter ambient sounds, and nice response for, say, rain drops hitting bricks with thunder rumbling in the background. It doesn't have a drop-out in the center, so a car passing doesn't sound weird. Perfectly natural stereo effect. Fits in a Rycote Baby Ball Gag - I should buy a real blimp, but that seems like one more big thing to pack, and I've been happy with the BBG so far. I'm quite happy with this mic - good balance between quality and portability/ease of use. I have stuff I've bought in the past that I end up not using because it's a pain, but this one is already working its way into my flow.

Sensitive, low noise, extended low frequency response

It took me a while to post this review because I did not have any sound recorder to test with. I did ensure that it did work by hooking it up to a friend's mixer, but it wasn't until we rented a Zoom F8 at work that I was able to hear what the BP4025 could really do. In testing at Caumsett State Historic Park, which is fairly quiet before 6am, I was able to pick up very clear bird songs, with a nice stereo image. And VERY low noise. I also realized I would have to go much further away from civilization in order to get quieter recordings. I could hear the LIRR (Long Island Rail Road) trains rumble from miles away, as well as a park ranger starting up his pickup truck from almost a half mile away, and completely out of sight. Suffice to say, this mic can capture low frequencies exceedingly well with its large capsules. I have wanted this mic since 2011, and it met all my expectations. Now to save some more to get a nice field recorder to go with the BP4025 :-)

Great to use

I've been using this mic for three months now, and I really like it. It's a one-trick, X-Y pony, but sometimes that's exactly what you need. Setup is quick and easy- I can be recording with this mic while I'd still be futzing with stereo bars and other mic pairs. Gives a good, realistic stereo field.

Can I use this as a mono mic for podcast if I do not connect one of the xlr's?

You could in that form just to connect oneside of the mic, just keep in mind that this mic is a condensor mic it still is sensitive and it will pickup ambience from the room if its not acousticlly treated.

Hi If I need to record sound effects and a quiet voice at a distance of 5-30 cm from the capsules, will the stereo image still be clearly present? I mean a clear separation of right and left.
Asked by: IEVGEN
Yes, because the Audio-Technica BP4025 X/Y Stereo Field Recording Microphone uses two individual capsules and offers the ability to keep the signal of each capsule independent of the other for individual recording, it will capture a stereo recording and depict a stereo image of the sound source it is oriented towards.

This mic can output both X/Y channels to each XLR ...

This mic can output both X/Y channels to each XLR cable, so I'm going to use it on a recorder like the zoom f3. Should I set the phantom power of each channel to 24V or 48V? Or is it both possible? The specs say '11-52VDC, 7mA typical (both channels total)' confuses me. Because this mic outputs two XLR cables, is it calculated by adding up the phantom power of the two? Please excuse the beginner's question.(24V+24V or 48V+48V ?)
Asked by: Studio
The dual XLR outputs of the Audio-Technica BP4025 X/Y Stereo Field Recording Microphone should both be connected to XLR input sources with phantom power engaged. Although 48V is the most common, this microphone will work with input sources offering 11-52VDC from each output.

Which capsules are in this microphone - cardioid or omnidirectional? If you use this microphone to record close quiet sounds and whispers, at a distance of about 5-15 cm from the capsule, will it have a strong effect of proximity and distortion, or will it be normal?
Asked by: IEVGEN
The capsules in the Audio-Technica BP4025 microphone are cardioid. This microphone would capture whispers at that distance very nicely.

question

What is the diameter of the shaft? I'm wanting to mount this in the mic holder on my Sony PXW-X70. It appears the mic holder would require a diameter of around 15/16 inch or 25mm. If the BP4025 shaft is narrower than that, are there mounting kits available to work with pro-level handles on cams? Thank you!
Asked by: Ricky
The mic holder attachment on most cameras have a diameter larger than most available microphones. We do offer a solution that allows mics to fit securely in these mounts. The ROCS Rubber O-Rings.

I'd like to use this mic on my Canon C70. Is there a XLR 5-pin female to dual mini XLR 3-pin male cable?
Asked by: Nik
The BP4025 comes with an XLR 5-pin female to dual XLR 3-pin male Y-cable. We do not a Y-cable with mini-XLR 3-pin male connectors, but you can use adapters to convert standard XLR male to mini-XLR male. The Laird Digital Cinema Premium 3-Pin Standard XLR Female to TA3M 3-Pin Mini XLR Male Audio Adapter (B&H # LARD1XFTA3M) will work or if you prefer longer adapter cables, you can use the Blackmagic Design Set of 2 Mini XLR to XLR Audio Cables for Video Assist 4K - 19.5" (B&H # BLAXLRMINI2). Both of these options will convert the standard XLR male connector to mini-XLR male for compatibility with the C70 mic inputs.

question

What is the width of the stereo pattern?
Asked by: Geoff
Unfortunately Audio Technica does not provide detailed specs regarding width of the pattern. The manual, which is available on the Audio Technica website does include some polar pattern diagrams at different frequency ranges that may help.
