The Rode SC4 3.5mm TRS to TRRS Adaptor features a high-quality shielded construction. It is designed to connect microphones with a 3.5mm output to TRRS smartphones and tablets. It is perfect for connecting a VideoMic to an iPhone while using the Rode Rec app on iOS. The adaptor features gold-plated contacts and grey color coding to indicate the TRRS output. While it is designed primarily for Apple iOS devices, it is still compatible with most Android smartphones and tablets. The SC4 is also compatible with stereo microphones where both left and right channels are combined into a mono signal for a TRRS.
