  • Overview


    Based on models originally developed for use in the broadcast of the Sydney Games in 2000, the BP4027 (14.96" long) and BP4029 (9.29" long) Stereo Shotgun models are engineered for high-end broadcast and production use. Both microphones feature independent line-cardioid and figure-of-eight elements configured in an MS (Mid-Side) arrangement with switch-selectable internal matrixing. These innovative microphones allow sound recordists the choice of selecting a left-right stereo output (wide or narrow) via the microphone’s internal matrixing system or choosing discrete Mid-Side signals for later manipulation, a flexibility not available from any other manufacturer.

    A switchable low frequency roll-off filter helps minimize the pickup of unwanted low frequency noise. These phantom-powered models feature a rugged lightweight design and sleek black color scheme, perfect for on-camera use.

    • Q:

      shorter cable available?

      I have my BP4029 mounted on a small camcorder. The configuration would be much better if I had a cable only a few inches long, preferably with angled connectors. Can you suggest a source (perhaps for a custom made cable or components to make my own)?
      Asked on 5/7/2014 by RichJ from Houston, TX, USA

      1 answer

      • A:

        The BP4029 Stereo Shotgun microphone requires 11-52V DC, 4 mA typical at 48V, for each channel. This is typically known as Phantom Power, and is provided by the input device, using an XLR - XLR cable. The cable provided with the BP4029 is a 5-Pin XLR-F to dual 3-Pin XLR-M.

        If you are using a 5-Pin XLR - 3.5mm (a/k/a 1/8th inch) cable, then power is not being supplied to the microphone.

        To shorten the included cable, an option would be modifying the included cable. You could also purchase this cable from the ATUS Parts Department, and modify that cable. HOWEVER, this would ONLY be recommended IF you are BOTH technically proficient, and proficient in soldering.

    • Q:

      What´s the difference between AT835ST and BP4029? Why was this microphone renamed? Are they using different elements in manufacture? Thanks.
      Asked on 2/24/2014 by Tuchosqui

      1 answer

      • A:

        The only differences between the AT835ST and the BP4029 are the color (AT835ST is grey, BP4029 is black), and that the BP4029 is RoHS compliant, which means the BP4029 is manufactured with lead-free solder. Other than those two differences, they are the same microphone with no specification changes.

        Thanks!

    • Q:

      placement of BP4029

      what is best hight for mic and distance from stage?
      Asked on 9/28/2012 by wyatolla from ridge spring, sc

      1 answer

      • A:

        Contrary to popular belief, Shotgun microphones do not make a sound-source appear closer (i.e. distance pickup). What a shotgun microphone does is reject sound from the side using its "ports". This is why it is used very heavily in production audio. To best describe it, it would be a lot like looking through a paper-towel tube. What you'd be looking at wouldn't be closer, but only be looking at what's in front of it. Same for shotgun microphones. The sound source wouldn't be any closer, but it would only be listening to what's in front of it.

        Like your ears, all microphones hear distance to varying degrees. For distance pickup, parabolic dishes are used. This being said, and I recommend this for any microphone placement, move the microphone around and stop when it sounds good. It's really that simple.
