By operating on an internal rechargeable battery or USB bus power, the Vmic5 Pro is able to work with cameras that don't supply plug-in power or phantom power. The rear of the mic features onboard controls for the three-stage gain adjustment, intelligibility-enhancing treble boost, and high-pass filter—helpful functions that let you optimize the signal quality at the mic instead of during postproduction. The mic comes two types of windscreens for recording indoors or outside in high-wind environments.
