CBS meter, as both were designed
for use by operators for real-time
production loudness monitoring.
The ‘Momentary’ meter does not
directly model the multiple loudness
integration time constants of human
hearing, all of which are faster
than 400ms. In addition, because
it is a simple integrated power
measurement, it does not model
‘loudness summation’ (which was
described in the section above on
the CBS meter).
Orban has recently released 2.0

extensive new features. The software
accepts two-channel stereo inputs
and displays instantaneous peaks,

All meters include peak-hold
functionality that makes the peak

split to indicate the left and right
channels. The PPM and VU meters
also displays the instantaneous

software is also supported.

Yamaha’s Flagship Nuage Console
A

n established name in the
broadcast industry, Yamaha
digital mixing consoles and
monitors are the equipment of
choice for many studios. However,
the company’s profile has been
significantly raised by the recent
introduction of the Dugan-MY16
auto microphone mixing card, the
CL series of digital consoles and
now the flagship Nuage postproduction system.
The Dugan-MY16 has already
made a substantial impression
on BBC One’s Question Time,
the UK’s flagship political debate
programme, making the work of
mix engineers Graham Backhouse
and Jeremy Farnell less fraught and
the conversation between panellists
more natural. “The Dugan-MY16
increases the intelligibility of the
panel and reduces overall colouration
of the broadcast sound, which
also keeps the broadcast sound
supervisor happy,” says Jeremy.
Another high profile production
to benefit from the Dugan-MY16
is 3nach9 (3 After 9), Germany’s
longest-running television talk show,

whose facilities have recently been
upgraded by the installation of a CL5
digital console and two Rio3224-D
I/O units alongside the Dugan-MY16.
“3nach9 has a complex setup
because, as well as the ‘round table’
format of the show’s discussions, it
features house musicians and live
performances by guest bands,” says
Cornelius ‘Conny’ Vogel, owner of
audio specialists Its A Bird, who
supplied the system.
“The programme’s technical
production company, Bremedia
GmbH, chose the CL system for
its quality, flexibility and excellent
sound quality. And with 12 wireless
microphones on each show, the
production team is really pleased
with the Dugan-MY16 card. It
has greatly simplified mixing
the interviews and debates, any
problems with feedback are a thing
of the past!”
The recent launch of Nuage from
Yamaha and Steinberg, has already
attracted a lot of attention from
the broadcast industry. Offering
unprecedented flexibility, it provides
post-production engineers with a

state-of-the-art
system from
two of the audio
industry’s most
highly respected
manufacturers.
