What’s hot at NAB? – Transmission efficiency in the spotlight


Harris Broadcast comes to the NABShow off a multi-week technology road show
focusing on transmission efficiency and audio networking for analogue and digital
radio broadcasters. The company will highlight new product enhancements and its
first MaxxCasting demonstration for large audiences.

MaxxCasting was recently introduced as a joint solution with Geo-Broadcast Solutions
to maximise audience reach, allowing broadcasters to fully utilise their FCC spectrum
allotments. The MaxxCasting architecture employs corresponding transmission and
control technologies to increase signal coverage via efficient, single-frequency
networks — often more effectively than traditional booster technologies.

Harris Broadcast will demonstrate a MaxxCasting solution featuring Flexiva low-power
transmitters, Intraplex SynchroCast3 IP based simulcast systems and Geo-Broadcast
Solutions’ network design architecture (including GPS and booster technologies) — all
outfitted in a compact Harris Broadcast outdoor enclosure to maximise equipment
protection and increase location options.

Also on show will be the Flexiva low-power transmitters in North America for the first
time (50, 150, 300 and 500 W), and a new transmitter option for integrated Orban
audio processing to enhance sound quality will be introduced. Flexiva customers can
add capabilities of Orban Optimod-FM 5500 series multiband digital audio processors
at a lower cost than a standalone unit, offering the same world-class audio
processing power and control. The optional plug-in cards are available for the entire
Flexiva transmitter range, extending from 50 W to 40 kW.

Harris will also showcase complete networked studio architectures for cost-efficient,
distributed audio systems covering multiple studios. The full demonstration will
include various PR&E consoles, networking systems and accessories to manage
seamless, tightly integrated studio workflows. This demonstration will extend to the
company’s Intraplex range of IP codecs, including the NAB debut of the IP Link 200, a
low-cost, multi-channel IP audio codec offering flexible device configuration, multi-
format support and “multicoding’ capability to minimise bandwidth usage for both
compressed and uncompressed audio.
