    3Dio Free Space Pro II Binaural Microphone

    1 In Stock


    XLR Phantom Power Output
    This upgraded version of the Free Space includes two balanced stereo XLR outputs that support phantom power. Power the Free Space Pro II using the 48V supply from a pre-amp, digital recorder or mixing console. The Free Space Pro II also includes an 1/8" stereo jack output that is powered by the internal 9V battery. The phantom power works regardless of the state of the 9V battery. 

    The Free Space Pro II comes standard with a 5/8" microphone stand adapter installed in the base. The microphone stand adapter is removable. The base of the microphone has a 1/4"-20 female thread mounting hole that can be connected to a hot-shoe adapter or used to mount directly onto a tripod or grip handle.

    The Free Space Pro II contains a 9V alkaline battery within the chassis. The exchangeable battery is used to power the microphone capsules.

    Why does it sound so natural?
    The Free Space Pro II captures sound just like we hear it in the real world with our own ears. When you listen back over headphones or 3D capable speakers, you hear the sound as if you were there at the time of recording. The effect is so powerful because the Free Space Pro II design is based on 13+ years of research into binaural technology and human hearing.

    Microphone Capsules
    The Free Space Pro II uses matched DPA 4060 hi-sensitivity capsules.
