Klein + Hummel O 810 and O 870
Active studio monitors
Now that modern production facilities require high-quality monitoring systems that can accurately reproduce anything up to the latest 7.1 discrete high-definition formats, Klein + Hummel has developed the O 810 and O 870 subwoofers to surpass these new demands. The O 810 and O 870 subwoofers are the perfect complement to Klein + Hummel's range of monitors and can be used either as a unit dedicated to reproducing the LFE channel, or as a way to provide low-frequency extension and increased maximum SPL for the main loudspeakers. The built-in 7.1 Channel High-Definition Bass Manager is compatible with all formats from mono to the latest 7.1 high-definition systems. Eight channels of analog, or an optional eight-channel 24-bit 192kHz digital input card, ensure flexible interconnectivity for modern studios. The latest amplifier technologies and acoustical components have been used to ensure the most accurate sound reproduction possible.
25-Seven Program Delay Monitor
25-Seven Systems' Program Delay Manager (PDM) is available in both IP audio and standard digital/analog I/O configurations. PDM offers full protection against unwanted broadcast content while providing excellent audio performance and 25-Seven's unique PD Alert system. PD Alert enables the program director and/or other key personnel to receive e-mail notification that program material was blocked from airing, including an audio file containing the content deleted by Program Delay Manager. PD Alert eliminates second-guessing about what was and was not aired during the incident.
APT Worldnet Oslo Module
Linear/PCM audio option
The Worldnet Oslo is now available with a linear audio module offering uncompressed audio quality over both IP and T1 links. The Linear/PCM audio option is in addition to the existing MPEG L2 option and the pro-grade, low delay Enhanced apt-X coding utilized in hundreds of STLs and studio links throughout the country. Also, APT's codecs now fully support SIP and SDP protocols. SIP ensures interoperability between audio codecs from different manufacturers and enables the negotiation of traffic across firewalls and external networks. With SIP and SDP on all the Worldnet Oslo audio multiplexers, APT's product range is now fully compliant to the N/ACIP standard set out by the European Broadcast Union.
Comrex BRIC TS
Bric TS is designed to make Access IP connections simple. Users can log in to the Bric TS server using a standard Web browser and create an account. A User Group is created and Access units are added to the account. After the account has been configured, Access units will automatically synchronize with Bric TS. A Buddy List is added to each Access unit's address book, which shows all users in the specified group as well as each codec's connection status and IP address. Connection between Access units is a simple point and click regardless of each unit's IP address and location behind firewalls or routers.

NAB, Ibiquity Push Effort on Updated HD Radio Exporter Technology
Las Vegas - Apr 13, 2008 - The National Association of Broadcasters and Ibiquity unveiled a partnership with four broadcast equipment manufacturers to accelerate the commercial development of HD Radio with the introduction of embedded Exporters. The goal of the effort was to reduce a radio station's cost to upgrade to HD Radio.
Until now, the HD Radio Exporter was a PC-based device. The new technology reduces the size and manufacturing cost of the hardware to solid-state DSP components. The HD Radio Exporter combines multicast audio channels and advanced data services along with a station's main audio channel into a format suitable for transmission. BE, Continental, Harris and Nautel are displaying the results of this effort in their booths at the NAB Show.
The project began in 2006, and the newly formed NAB HD Radio Technology Advancement Task Force was charged with overseeing the effort, culminating in today's announcement. The NAB has provided funding for this project, and NAB member stations are being offered a discount on purchasing the equipment if the order is placed at the convention.

Staco Energy Products Shows New Filter Line
Dayton, OH – Staco Energy Products showcased its new line of Staco Sine Active Harmonic Filters at the 2008 NAB Show. The filters dynamically correct a wide spectrum of harmonic orders and use power electronics to monitor a non-linear load, dynamically correcting every harmonic order from the 2nd to the 31st. Through an injection and cancellation process, the sine wave is restored and distortion is reduced to less than 5 percent THD, meeting stringent IEEE 519 standards.
Staco Sine technology moves power from the AC source to its DC electronic platform, then back to the AC source rapidly, to cancel out harmonics and equalize the sine wave. The high-speed process cancels high frequency output current, while it determines the precise value of injected load current. Designed to operate at levels that continuously adapt to rapid load fluctuations, Staco Sine is ideal for industrial and commercial environments including manufacturing, critical process lines, hospitals, data centers, HVAC, telecommunications, ac/dc/variable frequency drives, wastewater treatment and pumping stations, and more.
Models are available for 208 - 480Vac, 3-phase installations with an adaptive system frequency of 45/65Hz, and 120/240Vac control power. Wall mount or freestanding NEMA 1 enclosures are standard, with NEMA 12 or 3R enclosures available. Optional communications packages and user specific requirements can also be accommodated.

Radio Coalition Launches "Radio Heard Here" Campaign
Washington, DC - Apr 15, 2008 - The National Association of Broadcasters (NAB), Radio Advertising Bureau (RAB) and HD Digital Radio Alliance are launching a series of efforts to underscore the broadening versatility of radio content, the its technology and the continuing relevance of the medium in Americans’ lives. According to a release from the group, the multiyear initiative is expected to "turn up the volume on radio’s reemerging presence in a digital world."
“The sleeping giant has awakened,” said David Rehr, NAB president and CEO. “For close to a century, radio has had a ubiquitous and integral presence in our nation’s life, and today more than 235 million Americans turn to radio each week to be informed and entertained. Despite its universal presence, or perhaps because of it, radio’s abiding impact has been overlooked and underappreciated. The medium, however, has a bright future, and Radio Heard Here will help showcase radio’s robust advances, particularly in harnessing new technology and expanding and enhancing the diversity of its content.”
Radio Heard Here includes promotional and educational initiatives. Among them:
The effort sounds similar to the Radio 2020 campaign that was launched at the 2007 NAB Radio Show, except that this work specifies some of the actions that are planned, particularly those aimed at younger consumers. This younger audience is finding greater interest in forms of media other than radio.
Credit is due to the coalition for recognizing the declining radio audience, but we will have to wait and see if anything comes from the effort.
NRSC Adopts Updated Digital Radio
Las Vegas - Apr 12, 2008 - The National Radio Systems Committee (NRSC) has adopted an updated version of its in-band/on-channel (IBOC) digital radio broadcasting standard.
