Types of Microphones

Recording artists and music producers are already aware of the types of microphones. However, for the sake of knowing the real cause of this problem with the Focusrite Scarlett 2i2, let’s discuss a bit about microphones.

Dynamic Microphones (example: Shure SM57)

This type of microphone doesn’t require power to function. Once you plug it into your Scarlett, it’ll automatically work. Just turn up the gain, and you’re good to go.

Condenser (example: CM25 that comes with the Scarlett)

As opposed to dynamic microphones, condensers require power to function. That’s the reason why you can see the 48V button in your Scarlett. If you press this button, you are giving phantom power to your microphone for it to work.

Common Reasons Why Microphones Don’t Work

If your microphone works when you connect to other devices or directly to your computer, there’s no reason that it will not work with Focusrite Scarlett. However, the reality is that there are users who have a hard time

Poor Quality Microphone

There are really microphones that work well with your computer but may not be that reliable when plugging into an audio interface. How about using another microphone and see if it works well with Focusrite Scarlett. If it does, then, the microphone is the big problem.

Microphone Setup Gone Wrong

When switching from one microphone to another, you must be very careful. The reason why this article includes discussing the type of microphones is to emphasize to you that sometimes it is the wrong setup that will trigger the problem.

Just an example. Suppose, you are using a condenser microphone and things are working well. However, you find it to catch noise, so you change your microphone to a dynamic microphone. After you unplug your condenser mic, you replace it with a dynamic mic. This could be a problem.

If you have a balanced dynamic mic, then, it might not be affected. However, if you have an unbalanced dynamic mic, that could be affected. Hence, as a rule of thumb, you must disable the phantom power before unplugging the mic. And, if you are using a condenser mic, plug it in first before enabling the 48V phantom power.

Upgrading macOS

A user in Recording.org reported the same issue after he installed the latest version of his Mac. Setup was working fine in the previous Mac version and nothing was changed. In this case, one of two microphones isn’t working. It seems that even though two microphones were connected, only one is being recognized.

In addition, it’s also recommended trying another microphone (that’s known to work).
