Since the RØDECaster Pro lacks a dedicated 3.5mm input for microphones, you can't connect them directly, but there is a solution.
We recommend the VXLR Pro 3.5mm TRS to XLR adaptor with the RØDECaster Pro. If the microphone you are using requires plug-in power (such as the VideoMic GO, VideoMicro or a Lavalier microphones) you will need to activate phantom power on the channel that it is plugged into.
