The 7.9″ BOYA BY-K1 is a short adapter cable that converts an analog 3.5mm signal source to a digital Lightning output, making it ideal for connecting a shotgun microphone outfitted with a 3.5mm TRS female output port directly into a Lightning-equipped iOS mobile device such as an iPhone or iPad. The BY-K1 features a 3.5mm TRS male mini plug on one end and a Lightning male connector on the other.
