The MKE 600 mic is an all-around workhorse that can migrate from camcorder to DSLR. It can be powered by an AA battery or with Phantom power supplied from the camera, which makes it a great option for high-quality audio on a budget.
The ME 64 series microphone has optional power solutions and the convenience of exchangeable mics know as capsules. These capsules are attached to the power supply to complete the unit. The higher the capsule number, the more directional the pickup will be. You also have a choice of Phantom or battery power supplies. In my video above, I show more about these audio options and then catch some live sound to hear the quality of the mics.
