SC4 shielded adaptor cable is a 3.5mm mini TRS female to 3.5mm TRRS male connector.
It allows connection of a microphone with an integral 3.5mm output to TRRS smartphones and tablets.
The gold-plated contacts are colour coded, with grey indicating the TRRS output.
While the SC4 was designed to operate with Apple iOS devices such as the iPhone and iPad, it is compatible with the majority of Android devices on the market.
SC4 is compatible with stereo microphones, with both left and right channels combined to a mono signal to be compatible with TRRS.
