Unlike similar products, JAM and MiC are digital audio interfaces. These devices transform the analog signal of your voice or instrument into a digital signal that can be seen by an iPad, iPhone or Mac. For this delicate transition from analog to digital, Apogee has designed special high quality circuitry that preserves the true tone of the sound source so when you record into software like GarageBand, you are hearing the best possible representation. We call this, PureDIGITAL.
