The Q DSLR-Video PRO microphone kit was designed specifically for using with HD camcorders and DSLR cameras anywhere a high quality, compact and lightweight on-board run-and-gun shotgun microphone is needed. Although the microphone is extremely small and unobtrusive, the rejection properties are comparable to standard wide body shotgun microphones. The microphone is self-powered using two (2) AG4 1.5V batteries (included) but can also be phantom powered (balanced/low-impedance) using the optional QAD3 XLR adapter (batteries remain in mic for parallel operation).
