Wohler monitors at heart of Australian OB

Australia's Global Television is deploying Wohler audio and video monitoring equipment in two of its new state-of-the-art HD OB trucks. The first of the two HD OB units will hit the road by the end of 2008, with the second unit scheduled for completion in early 2009.

Wohler's compact HD/SD monitoring systems, supplied by Wohler's video products division PANORAMAdtv, will simplify high-resolution audio and video monitoring of Global Television's programming, which includes many of the country's highest profile reality, entertainment, and sports programmes.

Among the host of Wohler equipment purchased by the brodcaster, nine MON4-2W/HR HD/SD compact rackmount LCD video monitors will be installed in each truck, providing 36 individual widescreen displays in just 18 RU. The 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 alongside Tektronix Waveform Monitors in a Tektronix tub to facilitate detailed signal analysis.

Each OB 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 HD-SDI, SD-SDI, AES/EBU, and analogue 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 analogue channels. Eight high-resolution 26-segment tricolour LED bar-graph audio-level meters will provide accurate and instantaneous visual level monitoring at a glance.

"As the first units in Australia to deploy 3 Gbps 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 HD production."

The Wohler systems were supplied via Sydney-based Quinto Communications.
