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 firstname.lastname@example.org or 305-249-3110.

The hand-held recorder and player records to a 2GB built-in memory, recording PCM mono or stereo, or MP2/MP3. USB 2.0 offers fast a download time. The recorder is similar in size to an Ipod.
Axia Audio Iprobe
Network management software
This utility is a network maintenance and diagnostics suite that makes managing, updating and remote-controlling an Axia system easier. The auto-documentation feature queries and documents configuration settings for every networked Axia device. The organizer tool lets users perform many tasks such as gathering nodes into logical groups. The software works with any Axia IP-Audio network and runs on any P2-400MHz (or greater) PC, with 10/100 or 100/1000 Ethernet NIC running Windows 2000, XP or Vista.
Base station transmitter
This interruptible fold-back base station transmitter replaces the analog IFBT1 unit. The IFBT4 is a 250mW digital hybrid wireless transmitter for IFB and other types of radio links. It is compatible with all Lectrosonics 100, 200, 400 and IFB receivers, along with receivers from two other manufacturers. The transmitter features a backlit LCD with front-panel control for programming and operation. A selectable high-pass filter with settings at 35Hz and 50Hz allows for transmission of full audio bandwidth. The equipment is powered by 6V to 18V dc via a locking connector and is supplied with a quarter-wave whip antenna that is detachable from the 50Ω BNC connector on the rear panel.

Harris Intraplex Synchrocast3
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
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
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.
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.
