3DIO Free Space XLR

The 3DIO Free Space XLR is a professional binaural microphone that allows you to capture hyper realistic audio for unique videos, games, radio and more. The Free space XLR uses Primo EM172 microphone capsules that are extremely sensitive and quiet creating the perfect binaural recording. 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 EM172 capsules used in the Free Space XLR rolls off slightly above 10kHz.

3DIO Free Space XLR Features

XLR Phantom Power Output
This upgraded version of the Free Space includes two true transformer-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.

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.

The Free Space XLR 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 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 head microphone technology and human hearing.
