3Dio FS Pro II.

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.

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 & Battery.

Mounting & 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.

Unmatched Natural Sound.

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.

Unmatched Natural Sound.

Microphone Capsules.

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

The 3Dio FS, FS XLR and FS Pro II are stereo binaural microphones. The literal translation of the word "binaural" means 'of, relating to, or used with both ears'. How it works is that there are microphone capsules inside the two prosthetic ears. When listening to the microphone through headphones, it mimics the way humans hear the natural world. In other words, it picks up sounds the way that your ears pick up sound. The shape of the prosthetic ear manipulates the sounds and mimics a real human ear. It allows the listener to use spatial cues and localize sounds originating from above and below, in front and behind, and to the left and right of the microphone using only two channels. It transports the listener to the space where the recording took place.

Microphone Capsules.

Brilliant Audio, Incredible Versatility.

• In the recording studio for tracking and recording virtually any instrument.
• Field recording of the natural outdoor environment. The sensitive capsules capture such things as planes flying overhead, birds chirping, distant thunder, footsteps, etc.
• Simple stereo recordings in acoustically complex environments containing a plethora of sounds (airport terminals, tradeshows, highly populated areas, etc.).
• Measurement and calibration of open (over the ear) headphones.
• Filmmaking for spatial relevance and acoustic immersion.
• Podcasts for realistic 'at the table' perspective of conversations and interviews.
• YouTube videos for a professional audio experience.
• Assessment and evaluation of noise in industries looking to measure the impact of acoustic reverberation of various materials.
• Hobbyists looking to record in full 360 Degree professional audio.
