Applies to: all audio interfaces

There are two main types of connectors commonly used for microphones; XLR and 3.5mm jack. Microphones with 3.5mm connectors are typically designed to be used with consumer-grade devices like smartphones, laptops, cameras, and gaming headsets. These microphones generally require plug-in power (around 3-5V), which is supplied by the device they’re connected to.

In contrast, XLR connectors are the industry standard for studio-grade microphones. XLR mics output balanced audio signals and can require phantom power (typically 48V) provided by preamp they are connected to. Because of these differences in electrical characteristics (signal type, voltage requirements, impedance) 3.5mm microphones cannot be directly connected to XLR inputs without accounting for these differences.

Most audio interfaces and preamps, including those from Focusrite, are specifically designed for use with microphones that have XLR connectors, which ensures proper signal transmission and power delivery.

There are 3.5mm female to XLR adapters available that correctly convert the signals. Although such adapters should work with Focusrite interfaces, we have not officially tested them and therefore cannot guarantee their functionality or sound quality.
