About 3Dio Free Space

FEATURED REVIEWS

Im in shock at how well it works..

By LYNSEY S.

I love using this product for ASMR purposes and it sound amazing

3Dio Free Space XLR.

The 3Dio Free Space XLR Binaural Microphone is a high-quality binaural microphone. The integrated microphone capsules are extremely sensitive and quiet. The capsules have a very natural presence, perfect for binaural recordings. The Free Space XLR delivers portable, professional quality binaural in the palm of your hand.

The Perfect In Studio Tool.

The Free Space XLR has a very warm and solid response in the low to mid-range frequencies. This brings out the punch as well as provides low-end support for bass-heavy sounds. The frequency response of the capsules used in the Free Space XLR rolls off slightly above 10kHz. This is excellent for recording instruments with loud high frequencies like drum cymbals or strummed acoustic guitars. It also prevents any harsh effects that are sometimes associated with binaural recordings using smaller capsules.

The Perfect In Studio Tool.

XLR Phantom Power Output.

This upgraded version of the FS Microphone includes two balanced stereo XLR outputs that support phantom power. Power the Free Space XLR using the 48V supply from your pre-amp, digital recorder or mixing console. The Free Space XLR 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 XLR 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 XLR contains a 9V alkaline battery within the chassis. The exchangeable battery is used to power the microphone capsules.

XLR Phantom Power Output.

Unmatched Natural Sound.

The Free Space XLR 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 your own head was there at the time of recording. The effect is so powerful because the Free Space XLR design is based on 13+ years of research into binaural technology and human hearing.

Unmatched Natural Sound.

Microphones Capsules.

The Free Space XLR uses matched hi-sensitivity capsules for high powered versatility in numerous applications:

• 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.
