Global Television Upgrades OB Units with Wohler Monitoring Systems
‘s Global Television is installing
Wohler audio and video monitoring equipment in two HD OB trucks. Wohler’s HD/SD
monitoring solutions will simplify high-resolution audio and video monitoring
of Global Television’s programming, which includes sports programs.
“As the first units
to deploy 3Gb/s ready infrastructure, our new HD trucks represent leading-edge
broadcast technologies,” said Terry Manley, chief engineer at Global
Television. “The Wohler equipment is an optimal fit, enabling robust and
flexible monitoring of digital audio and high-resolution video while taking up
very little space in our truck. Space, power, and weight savings are critical
to cost-effective mobile production, and Wohler’s monitoring solutions meet all
these requirements while offering the premium performance our clients demand in
The installation of Wohler gear within the Global Television OB trucks includes MON
series rackmount LCD HD/SD video monitors, along with Wohler’s digital audio
monitoring bridges for HD/SD video and digital audio monitoring. Wohler’s MON high-resolution display monitors is ideal
for confidence monitoring of multiple video feeds in mobile applications where
space is at a premium.
The MON4-2W/HR features
four side-by-side 4.3-inch wide-format LCD panels, each with dedicated recessed
controls for contrast and brightness, native 16:9 aspect ratio, and selection
between 16:9 and 4:3 aspect ratios for SD-SDI signals, as well as tally
indicators and independent power and input termination switches. Each LCD is
mounted in a cylinder and thus may be rotated approximately 30 degrees in the
vertical plane for optimum operator viewing angles.
A total of nine
MON4-2W/HR HD/SD rackmount LCD video monitors are being installed in each
truck, providing 36 individual widescreen displays in just 18 RU. These units
will support the bulk of Global Television’s video monitoring activity. Seven
MON1-T/7W-HR 7-inch high-resolution HD/SD monitors will be mounted adjacent to
Tektronix Waveform Monitors in a Tektronix tub to facilitate detailed signal
truck will be equipped with 14 of Wohler’s AMP1-S8MDA HD/SD embedded audio
monitoring bridges and a single E MON-1/M audio bridge with built in Dolby
E decoding. The AMP1-S8MDA is a complete audio monitoring solution capable of
monitoring audio from
SD-SDI, AES/EBU, and analog
signal sources. The 1RU system processes and monitors up to eight channels from
an HD-SDI or SD-SDI bit stream, two sets of four AES/EBU signal pairs (balanced
and unbalanced), or eight balanced analog channels. Eight high-resolution
26-segment tricolor LED bar-graph audio-level meters provide accurate and
instantaneous visual level monitoring at a glance.
Communications supplied the Wohler gear for Global Television. “This will
be the largest deployment of Wohler monitoring equipment in an OB environment
said Tom Pavicic, general manager of Quinto Communications.
The first of the two HD
OB units will hit the road by the end of 2008, and the second will be completed
in early 2009.
