Boya BY-V01 stereo on camera microphone

Today, I’m looking at the microphone is the BOYA BY-V01 Stereo X/Y Mini Condenser Microphone.

This cheap stereo microphone is available on eBay and other locations, for about $30 Australian. I bought it wanting something cheap and low profile to sit on my camera most of the time, so I can get better sounding audio when I’m shooting, and I don’t want the bulk and clutter of the Rode Videomic.

From the outside, it looks OK. It’s a nice size, doesn’t stick out too far, and seems reasonably built.

But fairly quickly, you’ll establish that while it does work, it does have some fairly hard to ignore issues. I was hoping, being an externally powered microphone, it would a reasonable level of gain on the output of the mic, but it appears that there isn’t a whole lot of additional amplification given to the recording level.

This isn’t ideal for most DSLR cameras with microphone inputs. They are often build with budget preamps if they are luck enough to have mic inputs at all. The high noise recordings aren’t the greatest. Usually, the best thing to do is to have a microphone that has a strong output, or run an external mixer or preamp so you can turn down the inputs on the camera.

But that’s not the big issue on this microphone.

The sound recorded to camera appears to be flipped from what you would expect, With the left channel coming from the right, and vice-versa. That is a fixable issue by either flipping the channels in post, or re wiring the mic, but the point is, you shouldn’t have to do either. Also, to make matters worse, even if you do fix it, the sound image is not properly centered. If a sound is coming directly to the front of the mic, it will appear to come from one side of the mic.

I suspect the source of this problem comes from the fact that this microphone is not actually an X/Y microphone like advertised. If you pull the mic apart (like I did), It is actually appears to be a mid/side microphone.

Being  a mid/side microphone isn’t an issue (apart from the misleading labelling), I am guessing the side capsule is not performing as an accurate figure 8 microphone, and it is biasing one side just a little bit.

My verdict on this microphone is that its probably not worth the $30. I wouldn’t buy it again. If you have a camera with on board microphones (like most, if not all you’d consider mounting this to), You will likely get audio that is as good as, if not better than this microphone. Sure, there might be some purposes that see it being useful, like using it with the little deadcat in windy environments, that would probably yield slightly better results than the internal mic. The sound quality isn’t great, I’d say close to the on camera ones on the 650D, and it has issues with the stereo reproduction. I’d think twice about buying this mic. Save your money. for a little more you can get something a little better from a name brand like Rode, or Tascam. You’ll get much better results there.
