At the 2012 NAB Show, Harris Broadcast Communications will demonstrate how radio broadcasters can maximize transmission efficiency across all power levels — most notably for high-power HD Radio™, FM and AM broadcast operations.
Last year, Harris introduced its Flexiva™ range of quad-mode, solid-state transmitters in low-to-mid power models, boasting a single, highly power-efficient platform to support analog and global digital standards. This year, the company will introduce two new high-power models (30kW and 40kW) for broadcasters that need to minimize operating costs while covering large areas — including analog FM and high-power HD Radio via elevated sideband levels.
The Flexiva exciter will also debut at the 2012 NAB Show, featuring rock-solid digital, direct-to-channel modulation for maximum on-air stability. Web-based monitoring and control, a host of expansion options and upgrade paths to HD Radio and DRM+ make the Flexiva exciter a feature-rich yet simple and cost-effective alternative to the Harris FlexStar® HDx exciter. Both exciters are well-suited for Flexiva transmitters at any power level.
Harris will also demonstrate its high-power 3DX Destiny® AM transmitter range for Modulation Dependent Carrier Level (MDCL) applications, delivering exceptional power efficiency to high-power AM broadcasters via Harris Adaptive Carrier Control Plus (ACC+) systems. Harris ACC+ systems help AM broadcasters reduce average power consumption by approximately 35 percent — sharply reducing operating costs associated with high-power AM broadcasting.
All Harris Flexiva and 3DX transmitters leverage Harris® PowerSmart® technology to increase power density, reduce footprint, and improve reliability through simpler designs and better operational efficiency.
“Radio broadcasters continue to seek greater operational efficiency through compact and modular transmitter designs,” said Richard Redmond, vice president of product strategy and management for transmission systems, Harris Broadcast Communications. “Harris continues to develop new strategies and technologies that give our customers great performance with lower operating costs.”
Harris will also show its latest generation FlexStar importer and exporter models (HDI200 and HDE200) for more efficient management of HD Radio multicast signals comprising main and supplemental program audio channels. The NAB 2012 Show also marks the first spring show demonstration of IP backhaul capabilities within the Harris Intraplex® HD Link™ fixed microwave STL system. This upgrade enables tighter integration of RF and IP capabilities for single-channel or multicast program transport.
