The 3Dio Free Space Pro II comes with two matched, integrated DPA 4060 capsules mounted at the opening of the ear canal. The Free Space Pro II delivers a very sensitive and natural binaural recording. The extremely low noise floor of the DPA 4060 capsules results in a very open and dynamic binaural realism, especially during very delicate recordings. This sensitivity, coupled with the wide dynamic range of the microphone capsules, makes the Free Space Pro II ideally suited for professional studio recording and high-end recording binaural capture. The quiet 'openness' of the mic is great for field recording as well.
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.
Mounting 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.
Battery 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.
What's Included Every Free Space microphone ships with an 8" long 3.5mm (1/8") stereo TRS M2M cable. All Free Space microphones include the silicone ears. No need to purchase the prosthetic ear accessory.
