Audio-Technica BP4029 Overview

  • 1Description

The BP4029 (AT835ST) Stereo Shotgun Microphone from Audio-Technica offers two internally-matrixed modes which provide traditional "left-right" stereo. To accommodate varying acoustic environments, the user may select between a "wide" pattern (LR-W) with increased ambient pickup, and a "narrow" pattern (LR-N) which offers more rejection and less ambience.

In M-S mode, the BP4029 provides independent Mid and Side signals. This allows the Mid-Side balance to be adjusted as desired at the recording desk or mixing electronics, reducing the amount of equipment necessary in the field.

Independent line-cardioid and figure-of-eight condenser elements
Switch selection of non-matrixed M-S mode and two internally-matrixed left/right stereo modes

    Audio-Technica BP4029 Reviews

    BP4029 (AT835ST) - Stereo Shotgun Microphone is rated 4.8 out of 5 by 15.
    Rated 5 out of 5 by from The best equipment investment I've ever made! Iv'e been using this microphone for at least a decade now, if not longer. Not quite sure. It's been so amazingly dependable, with the most intense quality that when I compare it to things like the Rode or even the 416, this comes out so much ahead, cause it's close enough as a mono source, but having the stereo and M/S if you prefer is just wonderful. I've used this for pretty much everything I've done personally and for my clients. It's been just as rugged and dependable and awesome as anything I've ever seen or gotten. It's just a great all around performer, and yep.. i'm gushing. Get this while you can!

    Rated 5 out of 5 by from Stereo BUT you get three channels! I have a Rode Video Mic and a Sennheiser ME66 short shotgun mic. The BP4029 (AT835ST) is better than both of these mics put together... and then some. Why? Because it can be a mono short shotgun that is VERY loud and focused for its size (just a little longer than the Rode and much shorter than the ME66/K6). It is also a narrow and wide stereo mic AND it is also an M+S matrixed mic that can be easily separated into three channels (Middle and Left and Right) in post production audio editing software. Even with my handy Zoom H4N I can exploit mono, stereo and M+S recording with ease. M+S Matrixing allows you to balance a crowd in loud room with a single voice or a bird's chirping in a tree beside a babbling brook. If you shot with a DSLR and like to travel light, get this and a Zoom H4N - You'll be VERY happy!

    Rated 5 out of 5 by from Great stereo microphone I have purchased both the BP4029 and AT835ST stereo microphones and primarily use them for outdoor sports audio mixing environments such as baseball, football, soccer, etc. They also serve me really well for gathering ambient sounds, as I do professional audio recordings for TV and radio companies like NPR and National Geographic. You get 3 stereo modes with these microphones: L/R Narrow, L/R Wide, and M/S mode. They reproduce a really great stereo image, that is easily only found sometimes in mics costing $1500-$2000. I have recorded sources 50 yards away, and they come through very clean. My one complaint: wish the manufacturer would provide a thicker windscreen. Comes with a standard windscreen, that doesn't hold up too well, even in low level wind conditions. You definitely need to buy an additional thicker windscreen, windjammer, or windshield kit.

    Rated 5 out of 5 by from very natural sound quality The package arrived only a week after the order. I thank for very quick shipment. This microphone is designed for outdoor recording, but I use it indoor also with video camera for the concert, etc. This microphone is very natural sound quality, and surprised the quality, when recording the distance of 50-80 feets in narrow mode in piano recital. I couldn't feel the distance and so clear sound. This microphone is usable for a multi-use and look forward to outdoor indoor.

    Rated 5 out of 5 by from Wonderful Tool for Field Audio Just got this mic and immediately started using it for a run-and-gun style feature film and it is a charm! A great field mic for the price! I absolutely love the selectable x/y pattern!!! You can really hear the difference. Very convenient for capturing different types of sound sources, especially on the fly. If you need a solid stereo sound, but don't want to pay big dollar for it? This mic is it!

    Rated 5 out of 5 by from An excellent microphone for video! I've had this microphone for about two months, and I am extremely happy with it. I am using it primarily with a Canon XA20, but I have also used it with a Sound Devices MixPre-D, and it works great with both. I have used it on-camera at one wedding, and I am very impressed at how well it can pick out a voice from across a big table during a noisey reception yet still produce a pleasing stereo image. I have used it for interviews, both on-camera and overhead, and I feel like the result is better than a lavalier. On my XA20, I have it mounted (with the supplied O-rings) wih the foam windscreen butting against the camera's microphone holder. It seems quite long, but even with the lens zoomed at its widest, it is not in frame. (However, it does cast a shadow when using the infrared light.) Mounted this way, the front of the microphone does tend to droop down slightly in the holder. The microphone's frequency response curve is not exactly flat. The signal is a little weak in the lower frequencies and hot in the higher frequencies. A male voice could use a little EQ. Self-noise is imperceptible, but ambient room noise is more apparent in stereo than it would be with a mono microphone. Note that because this is a stereo microphone, it has a 5-pin XLR connection (most XLR audio connections are 3-pin monaural). A very well-made adapter cable is supplied that splits to two 3-pin XLR. The cable is 24 long, not including the connectors, which is quite excessive for a compact camera like the XA20.

    Rated 5 out of 5 by from Excellent Mic I use this mic with my DSLR and my Canon X10 & XF100. This mic performs extermelly well as a mono, stereo, M+S. It is compact, clear, crisp and worth every penny. I have mics twice the price and they are not as functional or clear and useful as these. Hence, I have 4 of them for all my video needs. The XLR inputs are great and work great with my X10 and XF100. With the Zoom H4N these mics work great on my DSLR.

    When shooting on a camcorder in the field, if I ...

    When shooting on a camcorder in the field, if I wanted only the center channel, so I could use the 2nd audio input on the camcorder for a wireless mic or some other input, which of the channels is mid if the mic is set to M/S and NOT doing an internal stereo matrix?
    Asked by: Matthew
    It ships with a 5-Pin xlr to 2 3-Pin xlrY-Cable. While It typically it is not marked on the cable which of the 3-pin xlr cable corresponds to which of the capsules, a quick and easy trial and error by independently testing each of the -pin xlr connectors, you should be able to figure it out in no time and with ease. I wish I would have a clear cut answer.

    Baass sound good?
    Asked by: Anonymous
    I upgraded from a less expensive, shorter mono shotgun, specifically looking to improve the quality of musical performance recordings--acoustic bands and orchestra performances. It's quite extraordinary. I've occasionally applied a mild amount of targeted EQ adjustment to bump up bass or to pull down higher "boomy" bass frequencies, but not because it's deficient in its pickup. Rather, my adjustments are almost always to counteract issues with the room acoustics. It's a marvel! While fairly long, it doesn't get into the frame on my Sony 1" sensor 4k camcorder, even when in the integrated mic mount.
