With the F-XLR-PRO adapter, you can now convert a 3.5 mm minijack to a 3 pin XLR, while also converting a 12-48V Phantom Power Signal to 3-5V Plug-in Power. This is a great for hooking up your on-camera microphone to your studio gear such as a mixer or recorder. The F-XLR-PRO is constructed from aluminum to maximize durability and the connectors are gold-plated to ensure and interference free signal transfer.
