Apogee JAM is a premium digital converter and preamp for use with almost any dynamic microphone. Apogee JAM features an input gain control wheel that is conveniently located on the side of the unit for easy thumb access and allows you to dial in the level of your microphone without requiring additional software. The JAM includes a cable that connects directly to the iPad?s lightning port, and its Female 1/4_ jack can be easily adapted to 3.5mm (mini) or XLR with a simple adapter (not included).
