 O constante avanço da
tecnologia, fornece ao audiovisual cada vez melhores e mais sofisticadas
ferramentas. Assistimos à transição generalizada da imagem para os formatos de
alta definição, e o som? O vulgar Stereo tambem já começa a parecer pouco, e já
se fala na emissão de televisão com som em 5.1.
A Holophone apresentou este ano na NAB 2006, o Holophone H4 super mini,
um microfone capaz de captar um campo sonoro em formato 5.1. Composto por 6
microfones independentes, tem disponível saídas em formato matrix sorround
stereo analógico, ou L, R, C, LFE, LS, RS independentes via mini jacks stereo.
O equipamento permite ainda a monição imediata em Virtual Surround, através da
tomada para auscultadores.

The
breakthrough Holophone H4 SuperMINI Surround
Sound microphone system delivers expansive 5.1
channel audio field capture in a super compact
package, mountable on any professional quality
video camera.
The
system offers an integrated multi-channel pre-amplifier,
virtual surround headphone monitor and matrix
surround encoder allowing truly professional
results for six-channel processing of live audio
from the concert hall and sports stadium to
fast-paced ENG applications. The H4 is ideally
suited for all live event television broadcasters,
live music producers and engineers and film
and video location crews who are interested
in real-time surround audio for delivery to
an ever increasing Home Theater audience. The
microphone has six independent microphone elements
that are output through either a matrix surround
encoded stereo analog output or six line-level
analog outputs (L, R, C, LFE, LS, RS) available
through three stereo mini-plug jacks. The SuperMINI
has additional capabilities that include an
input for an external, center-channel placed
shotgun or lavalier microphone to enhance sonic
opportunity options and features a zoom button
that increases the forward bias of the pick-up
pattern. It also includes Virtual Surround Monitoring
on headphones for real-time on-camera 3-D audio
monitoring of the surround field.
The
Holophone H4 SuperMINI Surround Sound microphone
system finally puts the power of high-quality
surround sound production into the hands of
the videographer on any level. The H4 SuperMINI
is precisely the right tool at the right time
for any video, film or broadcast production.

The
Standard for Surround Sound Recording
|
|
Holophone
Surround Sound Microphones are designed to make Surround
Sound capture and recording simple and accessible
to new and emerging markets in areas where it’s
been traditionally too expensive or too complicated
for production. With the HDTV and 5.1 channel home
theater revolution in full swing, content creators
are faced with the challenges of providing realistic
surround sound to a growing number of viewers in many
diverse markets. Holophone Products are specifically
designed to take cost and complexity out of the equation
for capturing surround sound, and to simply and instantly
provide a sonic three-dimensional feeling of “being
there” as the end result to the viewer.
