The 3Dio FS XLR Binaural Microphone is an upgraded version of the world’s most popular 3D microphone for ASMR, VR virtual reality, field recording and recording studios. Featuring two XLR outputs in addition to the 1/8" (3.5mm) stereo output, the XLR outputs are balanced to maintain a pristine audio signal for long cable runs as well and infinite use via phantom power supply. Used all over the world by hobbyists and professional recording engineers alike, 3Dio binaural microphones are a must-have for anyone looking for the best in 3D audio capturing.
What is Binaural?
Binaural is a recording technique that involves capturing sound using a stereo binaural microphone that is shaped and configured like two human ears. The 3Dio FS XLR binaural microphone is a special stereo microphone that contains two prosthetic, human-shaped ears with microphone capsules embedded inside each ear canal. Binaural microphones capture audio the same way your real ears hear sounds. Incoming sound waves are changed by the ear-shaped pinna of the microphone just like your ears would change the incoming sound waves. Our brains understand these changes as directional cues that allow us to pinpoint precise locations of any given sound. When you listen to binaural recordings using headphones, the result is a natural three-dimensional sound that gives the listener the sensation of being in the space where the audio was recorded.
How Does it work?
The FS XLR binaural microphone contains two matched, electret condenser microphone capsules embedded inside each ear canal and can be powered by the pre-installed 9V battery or phantom power via the XLR outputs. With the power switch in the ON position, the battery will last 300+ hours of continuous use (3.5mm output only). The microphone also contains a bass roll-off switch with a knee point of 160 hz (3.5mm output only).
XLR Phantom Power Output
The FS XLR includes two balanced stereo XLR outputs that require phantom power. Power the Free Space XLR using the 48V supply from your pre-amp, digital recorder or mixing console for infinite use. The Free Space XLR also includes an 1/8" (3.5 mm) stereo 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 battery is used to power the microphone capsules for the 1/8" (3.5 mm) output only when the power switch is in the ON position. A brand new battery will provide 300+ hours of continuous use.
The Free Space XLR uses matched hi-sensitivity capsules.
