5100 Mobile Surround
Microphone
The DPA 5100 is an
exciting new mobile surround microphone whose compact size and ease
of use come at no sacrifice to its stunning sound quality. It can
be regarded as a surround ambience adder, ideal for bringing truly
engaging surround ambience to sport events, documentaries and other
ambience applications for especially HDTV production. No external
signal processing is required. The versatile 5100 can be mounted on
a camera or microphone stand, suspended, or simply handheld via a
hand grip. Extremely lightweight and portable, the unit sports a
surprisingly robust build quality that is also highly resilient to
inclement weather conditions.
A completely self-contained “plug and play” solution
for 5.1 audio capture, the 5100 employs five miniature pressure
transducers that exhibit extremely low sensitivity to wind and
mechanical noise, low distortion, highly consistent low frequency
response and large dynamic range. Appropriate channel separation
and directionality are achieved through a combination of
DPA’s proprietary DiPMic™ (Directional Pressure
Microphone) technology, which mounts interference tubes on the
L/C/R omni capsules, and the use of acoustic baffles that further
preserve the accuracy of levels between the discrete analog output
channels.
The 5100’s three front microphones are time coincident to
eliminate comb filtering and ensure paramount frequency consistency
when downmixing to stereo or mono. In contrast, the rear
microphones, which feature standard omnidirectional patterns, are
optimally spaced from both each other and the front array to
simulate the most natural time arrival differences. The LFE (.1)
channel is comprised from a L/R sum, which is then attenuated 10 dB
in comparison with the signal from the main channels, in accordance
with the 5.1 format.
The end result of DPA’s innovative design approach is a
surround atmosphere that is rich, smooth and fully enveloping,
great in its coherence, channel separation and localization
accuracy.
The 5.1 output of the 5100 runs through a multi-pin Lemo connector
carrying all six channels electronically balanced, while an
enclosed five-meter (16 ft), six-pair Mogami cable breaks out to
six Neutrik XLR-M connectors.
Accessories included: Cable, thread adapter and outdoor cover.
Accessories available: stands, cables and windjammer.
