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