3Dio Omni Binaural Microphone


The 3Dio Omni binaural microphone is specifically designed to provide you with professional binaural audio for Virtual Reality and 360 degrees camera applications. The unit consists of 4 pairs of ears, each one is pointed 90 degrees from the adjacent pair which then provides a single point, 4 position binaural perspective of any audio equipment.


Records 4 different angles

The Omni Binaural mic captures stereo binaural audio from 4 different directions. 0 degrees, 90, 180 and 270 degrees, corresponding to the 4 different binaural angles (ear pairs) around the microphone. The Omni is an 8-channel microphone but is useful to edit and mix the output of the microphone in 4 pairs of stereo binaural tracks. 90 degrees being clockwise or 3 o’clock.


Immersive binaural audio

To record the output of the Omni microphone it is recommended to use an 8-channel recorder with 48V phantom power on each channel. The Omni is ideally suited for adding immersive binaural audio to your 360-degree video production. The Omni mic can also be used to provide binaural localisation/orientation freedom for engineers. Just place the mic where you want it, hit record and binaurally/positionally mix your audio sources in post.


Microphone Capsules

The Omni binaural microphone comes standard with 8 matched hi-sensitivity small diaphragm omnidirectional microphone capsules.



The Omni binaural microphone comes standard with a 5/8” microphone stand adapter installed in the mounting base. The microphone stand adapter is removable and the mounting 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. The Omni binaural microphone also comes with two mounting bases, one on the top and one on the bottom of the centre chassis of the mic.



The outputs of the Omni are a set of four 5-pin XLR connectors. Each output connector is associated with the ears to the respective left and right. You’ll be able to use the included splitter cables to break out the left/right signal to connect to your 8-channel preamp or to 4 individual audio recorders. The outputs require 48V phantom power.



The Omni microphone comes with four 5-pin to dual 3-pin XLR splitter cables to provide a total of 8 XLR outputs. The cables are 10ft in length.



The Omni microphone comes with a custom made, hard shell carry case for easy transport and ultra-safe storage.
