IBC2014: Show preview I

The International Broadcasting Convention is upon us once again. For six days in September, we’ll be seeing the great and the good of the broadcast world – including the staff of PSNEurope – descend upon the RAI convention centre in Amsterdam for more launches, demos and general hobnobbing than you can shake an antenna at. As always, make sure you stay tuned to the PSNEurope website, Twitter and Facebook during the event for all the latest updates as they happen – but here’s a preview to whet your appetites until then.

A licence-free wireless system offering uncompressed audio transmission, high RF performance and 128-bit AES standard encryption is making its debut at IBC.

Harman’s AKG DMSTetrad digital wireless microphone system features an integrated four-channel mixer and antenna front mount kit. With 24bit, 48kHz audio coding, it provides uncompressed studio-quality transmission and a linear frequency response for high vocal and instrumental performances.

Two sets are available: the DMSTetrad Vocal Set, including the DHTTetrad P5, and the DMSTetrad Performer Set, including the DPTTetrad together with a C111 L earhook microphone and the MKG L instrument cable.

The DK-Technologies T7 audio, loudness and logging meter (pictured right) has been boosted by adding loudness automation. Based on SMPTE timecode, this can instantly recalculate the integrated loudness value up to four hours back in time. The company says the enhancement, free of charge to existing and future DK T7 users, would save audio engineers from having to re-run programme material to hit their loudness target value.

DK-Technologies-1“Every engineer working with broadcast audio knows that hitting the loudness measure bullseye can be a very tedious and time consuming process,” says Uffe Kjems, DK-Technologies’ product marketing director. “Loudness automation adds a cool and practical feature to the DK T7 – at no additional cost.”

GatesAir‘s Maxiva UHF series comprises the ULXT liquid-cooled model, for medium-to-high power broadcasts, and the UAXT air-cooled model for low-to-medium power requirements. The broadband amplifier design increases power density in both models, reducing transmitter footprints and rack space requirements by up to 75 per cent, the company says. GatesAir adds that this design also simplifies maintenance, as it offers modularity, lighter weights and fewer parts.

The entrance of Hall 8 is apparently the place to hear announcements of major new advancements in broadcast audio technology at IBC 2014.

HHB and audio post subsidiary Scrub have been joined by co-exhibitors Dynaudio, Mogami, Roland and TC Electronic. The latter is launching several new additions to its production and broadcast product ranges.

The reseller advised that, with the DPP’s file-based delivery target of 1 October imminent, compliance with the EBU R128 loudness standard is an extremely relevant subject for IBC visitors. Accordingly HHB is exhibiting the latest loudness metering and correction technologies in hardware and software for acquisition, production and transmission, from manufacturers including TC Electronic, Wohler, Dolby and Nugen Audio.

Visitors are also invited to collect a free copy of the latest issue of the Pro Audio Report, a 36-page HHB publication packed with new technology and in-depth features. “With the perfect position at the entrance to Hall 8, the HHB Stand is not just a magnet to see the latest and greatest audio technology but also the perfect meeting point to catch-up with fellow professionals,” says HHB director of sales Martin O’Donnell. “Everyone is welcome and refreshing cold beverages await.”

New DAB combiners, bandpass filters and mask filters are being showcased at IBC by Jampro. The company describes its RCCC-DT4-DAB filters and combiners as extremely stable and easy-to-tune units that meet all the requirements of the Eureka 147 specification, while RF System Series RCED-XXX-DAB reflective bandpass filters are designed to provide high mask performance for low and medium power DAB transmitters.

JBL Professional-1The RCBC-D06-DAB bandpass filter features invar tuning rods to create temperature stability and high-Q aluminium cavities, and the JVD dipole side-mounted antenna – aimed at DAB Band III and TV broadcasting applications where low wind loadings are required – is designed for vertical polarisation, with a galvanised and stainless steel construction that is intended for many years of performance, even in the harshest environments.

The 3 Series studio monitors, the first studio monitor line to incorporate JBL’s patent-pending Image Control Waveguide, will been introduced at IBC.

Harman’s JBL Professional 3 Series (pictured above right) features two models: the LSR305, a five-inch powered studio monitor, and the LSR308, an eight-inch powered studio monitor. The LSR305 boasts a response of 43Hz to 24 kHz and a peak SPL of 108 dB, while the LSR308 features a response of 37Hz to 24 kHz and a peak SPL of 112 dB. The monitors also feature Class D amplifiers, a long-throw woofer and a damped woven composite tweeter.

IBC plays host to the launch of a brand-new audio mixing console on 12 September. The new member of the Lawo product family, which the company claims boasts high performance, a new face and an advanced feature set, is set to extend Lawo’s application range and round up the company’s product portfolio.

Also on show is the new crystal radio console (pictured below right). This entry-level mixer offers a redesigned user surface in a slim chassis and a new ergonomic handrest. The redesigned crystal base unit features power supply redundancy and optimised expansion slots for easy addition of I/O cards.

LAWO-1-PREVIEWAn updated range of 3G monitors, enhanced with integrated audio loudness logging and V-Chip decoding features, are being showcased at IBC by Plura Broadcast.

Plura says the new software-defined features for its SFP-3G and PRM-3G monitors will aid quality control across broadcast and production workflows without adding complexity or increasing form factor.

The company currently offers standard live monitoring of digital audio loudness LFKS levels, but will introduce new timeline-centric features that allow broadcasters to quickly review and troubleshoot fluctuations in audio loudness over a given time period.

The new Studer Vista X digital mixing console is being unveiled at IBC, based around the CPU-based Infinity processing engine.

The Vista X retains Studer’s patented Vistonics and FaderGlow user interface, but provides control of 800 or more audio DSP channels and more than 5,000 inputs and outputs.

At the heart of the system is the Infinity DSP core, which uses CPU-based processors to provide large numbers of DSP channels for high-resolution audio processing and mixing. Studer claims that this is the first time more than 800 audio channels have been processed in a single CPU-based board. Until now, most audio DSP has used SHARC or FPGA chips.

A large-format audio mixing desk/console featuring IP networking, in addition to TDM connectivity, will be showcased by Wheatstone.

Wheatstone-1The new Dimension Three TV audio mixing desk (pictured right) offers I/O layering and profiling of channels into any configuration on the surface. Mixing, I/O and processing all take place in a separate network rack unit, with any channel able to connect to any audio source, using any preferred audio format at any time, including HD/SDI, AES, MADI, AoIP, analogue or TDM.

The Dimension Three is based on Wheatstone’s Gibraltar mixing engine, which is capable of 1,024 channels of simultaneous digital signal processing. It offers speciality features such as automatically crossfading between inputs as the switcher or automation system cuts or dissolves between video sources, as well as optimising levels of group microphones during a dialogue. In addition to Audio-Follow-Video (AFV) switching, the Dimension Three includes audio processing on every input channel and on all major output busses, all with resource sharing through the network.
