    News from the Convention

    Audemat-Aztec Releases Goldeneagle HD Ver 1.4
    Audemat-Aztec has released software version 1.4 for its Goldeneagle HD monitor. The new release is based partly on input from customers to improve the unit and is available free of charge.

    Many new features are available in the update. First, the Goldeneagle HD is now capable of displaying the complete NRSC (5A) mask for AM and FM HD Radio stations. The unit can also monitor the station's compliance with this mask on a regular basis and issue alerts for out-of-tolerance conditions. Another new feature is automatic monitoring of the digital/analog audio time alignment, with alerts via e-mail, SMS, SNMP trap or voice call.

    New capabilities have been added to the modulation monitoring feature that was introduced in version 1.3. Peak weighting and filtering have been added to provide a more accurate measurement consistent with traditional analog measurements. The modulation monitor can now measure modulation on the 67kHz and 92kHz subcarriers. The unit can now be configured to monitor the entire FM spectrum and send alerts when changes in RF level are detected.

    Other enhancements include sticky frequency selection, maintaining 30 days of recorded readings, scheduled recording of analog or digital audio, time alignment measurements accessible from the touch screen, user-controlled time-out for real-time measurement and audio listening, and a new maintenance mode.

    To obtain the software update, contact Audemat-Aztec Technical Support Manager Tony Peterle at or 305-249-3110.

    Broadcast Electronics to Host HD Radio Seminar
    Lessons learned from the first 1,000 HD Radio stations will be the focus of the Broadcast Electronics engineering seminar at the NAB convention. The seminar will be held at the Las Vegas Convention Center on April 14 in room N211.

    The seminar is free to all broadcasters. Go to to register.

    More Products

    Harris Intraplex Synchrocast3
    Simulcasting product
    Booth N2502

    This third-generation simulcasting product allows radio broadcasters with overlapping transmitters to create audio synchronization in multiple-transmitter networks. The system uses an Intraplex T1/E1 multiplexer or Net Xpress IP multiplexer platform with GPS digital timing to enable a network of transmitters to increase coverage areas and reduce interference, especially in geographical regions with difficult terrains. The product offers more efficient use of network bandwidth by the timing system, allowing users to allocate additional bandwidth to voice and data transmission.

    Wheatstone Evolution 6
    Booth N7111

    The E-6 Surface, the E-series Studio Satellite and the E-series Network Switch combine to achieve a networked audio system. Each studio operates independently yet can share all the sources and mixes through the E-series Network. Switch without traffic limitations, audio latency, or machine control delays. The E-6 Surface features event recall, bus-minus and mix-minus and four aux mixes—all with dedicated talkback systems. The E-6 also features four monitor outputs and standard EQ, dynamics, panning and mic processing on all channels (simultaneously). It supports multiple arrays of programmable input channel and master panel switches for customized functions like phone, intercom, salvos or machine commands.

    JK Audio Daptor Three
    Wireless audio interface
    Booth N9426

    Using Bluetooth wireless technology, this interface connects to the user's cell phone like any other Bluetooth-enabled headset. The interface allows balanced and unbalanced connections to a cell phone. It will also connect to other products, such as a laptop, that allows a similar headset connection. Features of the unit include XLR balanced line input and output and a 9Vdc battery.

    Convention Events

    NHK's Nishiyama to Keynote BEC
    Washington - Jan 29, 2007 - Hirokazu Nishiyama, managing director of Japanese public broadcaster NHK, will provide the keynote address for the 61st annual Broadcast Engineering Conference at NAB2007. The Broadcast Engineering Conference provides a forum for engineers to discuss technology's effects on future trends in the broadcast industry. Nishiyama will discuss new broadcast services such as mobile, HDTV, IPTV, and VOD and the opportunities these advanced services create for broadcasters. He will also discuss the various applications that make ultra-HDTV, which offers 16 times the resolution of current HDTV, a promising technology for the future.

    From 1989 to 1995, Nishiyama served as executive deputy president of NHK Enterprises America, where he played a major role in production of HD programs in the United States. He was later appointed associate director of the Engineering Administration Department, where he was responsible for developing broadcasting equipment for HDTV.

    Nishiyama served as the director-general of the Engineering Administration Department in 2004, overseeing all aspects of broadcast technologies within NHK. In 2005, Nishiyama was appointed managing director. He currently oversees all engineering activities and supervises the Engineering Administration Department and the Science and Technical Research Laboratories.

    Out and About in Las Vegas

    There are many interesting things to see in Vegas outside of the NAB convention. Here are a couple of ideas if you have the time:

    Grand Canyon Skywalk: The Hualapai tribe owns one million acres on the western rim of the Grand Canyon. It intends to build a glass bridge that will allow visitors to virtually walk on air 4,000 feet above the floor of the canyon. Click here for a picture of the skywalk. For more information visit The Skywalk is expected to open on March 28.

    For those curious about the human body, or maybe just for morbid curiosity, visit the new exhibit at the Tropicana called Bodies...The Exhibition. The exhibition showcases 21 whole bodies and more than 260 organs and partial body specimens. These real human bodies have been dissected, preserved and respectfully presented, providing a view of the complexity of our organs and systems. Exhibit hours are 10:00 a.m. to 11:00 p.m. daily. Tickets are $26. For more information visit
