Our setup is pretty simple: a laptop, a Yeti microphone, and the three of us huddled around it. I have some wild idea that someday we’ll each have our own mic and be sitting in real sound booths, like an honest-to-god radio show, but we haven’t reached that level of crazy yet. The multiple-mic setup would be handy, though, because I think it would give us more options during editing: for example, the volume of each host’s voice could be adjusted independently.
Recording the show has gotten more complex since then (we have videos now; check out our YouTube channel), but the multi-microphone dream has become a reality. Now we have two Yeti microphones, and we record them simultaneously.
This wasn’t easy to get configured, though. There isn’t a lot of information about this online, so I’m writing this mostly as a warning to others and as bait for Google.
TL;DR version: out of the box, you cannot use multiple Yeti microphones on the same Mac.
The longer version: it is possible, but you’ll need to send one of the mics back to Blue, the manufacturer, for a firmware update.
There are plenty of tutorials online that show you how to record multiple USB mics at once using your Mac. They usually go something like this:
Scott and I have exactly the same microphone: the Blue Yeti. When we tried to follow these steps, things stopped working around step 4: only one microphone would show up in the list as an available device. Each one worked by itself, but if we tried to use both at once, only one would actually work.
USB devices may have serial numbers. For the devices that have them, those serial numbers would ideally be unique to every individual device: a special snowflake, no two alike.
In reality, this isn’t always the case. Sometimes two devices will have the same serial number. This may or may not be a problem. In our particular case with Yetis, it’s a problem.
If you plug a Yeti microphone into your Mac and open the System Information app, you can actually see the serial number for yourself. Highlight the Yeti Stereo Microphone entry, and you’ll see a line that says something like
Serial Number: REV8
I tried this with both my microphone and Scott’s, and they both were using
REV8 as their serial number. Whoops! I suspect all Yeti mics use this number.
After emailing the support team at Blue, they told me they could update my mic with a new serial number: I just needed to provide proof-of-purchase, mail them my microphone, and they’d send it back with a new serial number.
It took a week or two, but this definitely did the trick: Blue reprogrammed
my mic to use the serial number
777, and we’ve been successfully using
both microphones together ever since.
Other models from Blue may also be affected; I’ve seen people online mention very similar issues when trying to use two Snowball microphones together, and I suspect it’s the same underlying problem.
This problem was surprisingly hard to track down, so hopefully this helps someone else figure out their microphone woes.
I spend my days creating software at Apple, and I occassionally write or make videos that I share here.
