Harris Corporation to Deliver High-Power AM to Rádio Globo in Brazil


Harris HD Radio-ready 3DX™ transmitters headed for sites in Brazil’s two largest cities

CINCINNATI, July 10, 2006 — Harris Corporation (NYSE: HRS) today announced that Rádio Globo, a highly influential radio broadcaster throughout Latin America, has once again selected Harris technology and expanded its use of the Harris 3DX™ family of products for high-power AM transmission in Brazil. The transmitters, destined for sites in Rio de Janeiro and Săo Paulo, will also be outfitted with Harris DEXSTAR® exciters for HD Radio™ broadcasting.

“As a leading radio company, it is crucial to have the right technology in place to ensure that our listeners can receive the best possible audio quality and content,” said Rubens Campos, general director of Sistema Globo de Rádio (Rádio Globo). “Going digital, especially on the AM band, is the only way that radio can grow its audience. We believe that Harris offers the best combination of high-quality equipment, competitive prices and excellent customer service to help us move forward with HD Radio and offer a more attractive on-air product to our listeners and advertisers.”

Rádio Globo, a long-time Harris customer, decided to install additional, higher-power 3DX systems based on its familiarity with the transmitter’s high audio quality, power efficiency and maintenance-friendly operation. The company currently has a 3DX™-50 transmitter at the Belo Horizonte site broadcasting analog and HD Radio signals since September 2005. Now, Rádio Globo Rio and Rádio Globo Săo Paulo will install 3DX™D-200 transmitters, the newest additions to the industry-leading 3DX family. Radio CBN Rio will also install a recently launched 3DX™D-100 transmitter, while Radio CBN Săo Paulo will add a 3DX™-50 to its family of transmitters. Redundant exciters and power supplies will be integrated, ensuring that each station will remain on the air at all times.

Harris 3DX transmitters employ the company’s Direct Digital Drive, high-power, AM transmission technology to improve signal linearity. The design drives each internal power amplifier module with low-level signals, eliminating the RF driver stage to conserve energy, reduce complexity and improve reliability — ultimately reducing operational costs. Rádio Globo will realize operational cost reduction benefits from the transmitters’ 87 percent overall AC to RF efficiency. The transmitter features automatic reassignment of modules in the event of failure, and the design also allows engineers to perform maintenance, such as the replacement of PA modules, while remaining on the air. Each transmitter will also come with a comprehensive Harris eCDi® transmitter control and monitoring system, offering in-depth diagnostics and an intuitive, user-friendly interface via Internet protocol.

Rádio Globo has also purchased three HT35CD FM transmitters for stations in Săo Paulo and Rio de Janeiro, three BMXdigital on-air consoles and one additional 3DX-50 high-power AM transmitter, originally installed at Radio Tiradentes in Belo Horizonte.

“Rádio Globo’s leadership and commitment to HD Radio is an excellent sign for the future of digital radio not only in Brazil, but throughout Latin America,” said Nahuel Villegas, Harris Broadcast Communications Division’s regional director of sales for Latin America and the Caribbean. “Harris has consistently demonstrated a strong commitment to digital radio across the region, and has spearheaded HD Radio demonstrations in Brazil, Mexico and Argentina, among other countries. The introduction of HD Radio in Brazil last September was a major step forward, and we are very pleased to continue growing our strategic relationship with Rádio Globo as they continue to push forward with digital radio.”
