Classis MicrophonesThe GM gooseneck range includes compact 100mm goosenecks with mini shock-mounts up to 500mm versions with 3-pin XLR connectors. New BM boundary microphones are some of the most discreet and attractive on the market and the OM overhead range offer vari-ous mounting plates and cable lengths to suit almost all applications. Features including new high quality finishes, redeveloped housings and slimmer gooseneck stems make the Classis range an attractive and practical installation option.
Using revolutionary
technology,
a combination
of beyerdynamic
RFi proof microphones
and high definition
Biamp echo
cancellation
ensures that
you enjoy a
crisp, clear
conference
every time.
A meeting is
loosely defined
as two or more
people coming
together – but Biamp equipment is helping redefine where and how meetings take place. From broadcasting company meetings across a 500-acre facility to pioneering new sound possibilities in convention and conference centres, Biamp products facilitate new configurations to connect people better. Crisp, clear audio is now available for any distance conferencing application.
Portable Conferencing The needs of conference or discussion systems within the corporate sector, local government, education and judicial environments have evolved to a very high level with the need for systems to be portable and flexible. Wireless technology has now also become a major factor simplifying installation within both fixed and temporary situations and the use of digital transmission provides encryption necessary to keep sensitive discussion secure. The MCW-D system from beyerdynamic offers you all options in one flexible package.

The UK government’s media regulator OFCOM has announced a change to the frequencies available for UHF analogue wireless microphones in the UK. From July 2012 onwards any wireless microphones operating in the 800 MHz spectrum (television broadcast Channel 69, which uses frequencies 854MHz to 862MHz) in the UK must cease operation. The one exception to this is microphones using the 800MHz spectrum in London, where they must cease use from October 2012. Most radio microphones sold in the past 10 years will operate in the Channel 69 frequency range and therefore the majority of wireless microphone users could be affected by this change.
So why do
we have to
move from Channel
69?
Because of
the ever expanding
market of mobile
phone services
in Europe,
the decision
to re-allocate
large chunks
of radio frequency
spectrum has
been taken.
These spectrums
have been cleared
of their traditional
users (of which
wireless microphone
users are one)
and the spectrums
put up for
auction. The
auction for
the 800MHz
spectrum has
ended and mobile
phone services
using these
frequencies
will commence
in late 2012.
So
if I can’t
continue to
use Channel
69 - what can
I use?
OFCOM has set
aside frequencies
in and around
Channel 38
(frequencies
606MHz to 614MHz,
previously
used by radio
telescopes
in the UK)
for all users
of current
Channel 69
wireless microphone
users to migrate
to. Radio microphone
hardware operating
in these frequency
ranges is becoming
available in
the market.
Beyerdynamic
already has
replacement
wireless systems
available for
use in Channel
38, in the
form of the
OPUS 600-series.
These products
can lawfully
be used from
now until 2012
and onwards
and are available
to purchase
from Saville
Audio Visual.
A licence for the use of these systems must be purchased from the Joint Frequencies Management Group (http://www.jfmg.co.uk) who are the frequency band manager for wireless microphones in the UK.
What
if I don’t
move?
Any radio microphones
still using
frequencies
between 854MHz
and 862MHz
following the
change will
be faced with
interference
from the mobile
phone services.
Furthermore,
should any
wireless microphones
found to be
interfering
with these
mobile phone
services, the
owners of the
microphones
may be open
to prosecution.
Is there an
alternative?
Systems using
frequencies
in the Channel
70 spectrum
(863MHz to
865MHz) can
still be used
after 2012.
Channel 70
is immune from
the changes
occurring to
Ch69 and below
in the 800MHz
spectrum. Many
current systems
can work in
the Channel
70 spectrum
- which is
licence-free,
but only a
small number
can be used
simultaneously.
In general,
if you need
to use more
than four at
the same time,
Channel 38
products would
have to be
used.
