The SC4 is a high-quality shielded adapter for connecting a microphone with a 3.5 mm output to the TRRS socket of a smartphone or tablet. It is suitable for users who want to connect their RodeVideoMic to their iPhone and record with the Rode Rec App (iOS). The gold-plated contacts are color coded: Gray indicates the TRRS output. Although the SC4 was originally designed for an iPhone or iPad, it is also suitable for many Android-based devices. Although it is possible to connect stereo microphones to the SC4, these channels are combined to form a mono signal for compatibility with the TRRS input.
