3Dio Free Space Pro II Binaural Microphone


The 3Dio Free Space Pro II comes with two matched, integrated DPA 4060 capsules that are mounted at the opening of the ear canal. The 3Dio Free Space Pro II delivers incredibly sensitive and natural binaural recordings. The extremely low noise floor of the DPA 4060 capsules provides you with very open and dynamic binaural realism, especially for those delicate recording applications. This level of sensitivity, coupled with the wide dynamic range of the microphone capsules makes the Free Space Pro II perfectly suited for professional studio recording, high-end recording binaural capture and field recordings.


XLR Phantom Power Output

This upgraded version of the Free Space includes two balanced stereo XLR outputs that support phantom power. Power is supplied using the 48V supply from a preamp, digital recorder or mixing console. The Free Space Pro II also includes a 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 that is installed in the base and is removable. The base of the microphone has a ¼”-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.


Why does it sound so natural?

The Free Space Pro II captures sound in the same we hear it in the real world with our own ears. When you listen back with headphones or 3D capable speakers, you’ll be able to hear the sound as if you were there at the time of recording. With Free Space Pro II being designed with 13+ years of research in binaural technology and human hearing, it is no wonder you’ll achieve some of the most realistic recordings possible.


What's Included

Every Free Space Pro II microphone comes with a 4.5 ft long (1.5 m) 3.5mm (1/8") TRS to dual 1/4" splitter cable. Plus, all Free Space Pro II microphones include silicone ears. There’s no need to purchase the prosthetic ear accessory.
