ollowing the ambitious broadcast
of the Coronation of King WillemAlexander, the United OB14 mobile
truck was in action again at the
2013 UEFA Europe League in
Amsterdam’s Arena.
The truck, equipped with its Lawo
mc²66 digital broadcast console and
DALLIS I/O system, found itself at
the centre of another mission critical
international broadcast. This time
it was of the Chelsea-Benfica
encounter on May 15th awaited by
a worldwide audience, where United
provided the live audio feed to the
event’s TV Compound to accompany
the 35-camera production that was
provided to 15 visiting major sports
broadcasters in 5.1 surround.
The mic set-up used a surround
microphone in the catwalk of the
stadium, with four omnis suspended
from the catwalk in the corners of
the stadium. On the pitch were 14
shotgun mics, and all of the pitch
cameras had microphones whose
feeds were collected by the truck.
An essential part of the audio
operation were the Lawo’s audiofollow-video (AfV) function and VSM

(Virtual Studio Manager) control
software from L-S-B Broadcast,
which is integrated into the OB14
console and enables the direct
assignment of AfV events to the
camera tallies.
“These AfV audio sources were
each routed to a subgroup, so
effectively there was one fader
to control how much detail of the
camera mics could be heard in
the mix,” United’s Jeroen ‘Huub’
Lelieveld explains. “This software
controls all equipment in the truck,
and opens the faders assigned to
specific cameras.
Lelieveld’s United colleague
Mischa Kortleve mixed the action
from the ﬁeld, while he watched the
video line cut and controlled how
much surround atmosphere and
AfV sounds were added to the mix,
making sure that the sound matched
the “feel” of the picture.
“We created three video feeds,
each with different pictures and,
at some point, different cameras
and interview/stand up positions,”
Lelieveld says. “VSM is able to

GPIs for different video outputs, so
while we concentrated on mixing
the main feed, the other two feeds
were mixed automatically, with
different faders being triggered by
the video mixer.”
In addition to the de/embedder
cards in the OB14 mobile’s mc266,
the console is partnered with a
Lawo V_pro 8, which offers video
bridging facilities – decoding
signals from different formats, then
transforming them to another.
“We had a total of six outgoing
feeds with Dolby E and another 15
or so video feeds with non-Dolby E
embedded audio,” says Lelieveld.
“For this huge production our usual
de/embedder cards in our mc266
weren’t enough so we had an
additional V_pro 8.
“OB14’s mc266 has a DALLIS
frame full of Lawo de/embedders,

however, with three (redundant)
video feeds and many extra feeds
going into the Technical Operations
Center (TOC), we needed more
embedders. For this, the Lawo V_
pro 8 was perfect – connected to
the mixer via MADI, all video and
audio delay needed to compensate
for Dolby E decoding was handled in
this box, with no need for separate
video frame synchronisers.
“Delaying the video and PCM audio
in a video feed that has Dolby E
requires just the click of a mouse
instead of our usual use of an extra
frame synchroniser. Every video
channel has up to eight frames of
delay, and we can embed up to 32
channels of audio per video channel,
also at the click of a mouse.”
It was Chelsea’s night on the
ﬁeld, but the winning formula for
the sound went home with United.
