Harris Corporation Introduces HPX Series

Harris
Corporation introduced the HPX Series at NAB Radio Show in Austin TX. The HPX Series is a range of high-power tube
transmitters designed for HD Radio broadcasting. HPX transmitters provide
a high-power solution in a compact, power-efficient, and cost-effective
package. HPX transmitters are also available in analog FM-only or common
amplification HD Radio versions, and incorporate an advanced transmitter
control system.
The
compact design of the HPX transmitter utilizes matching amplifier and power
supply cabinets to minimize the footprint at the transmission facility.
Its common architecture at all power levels simplifies the upgrade path for
radio broadcasters who wish to migrate from analog-only to an HD Radio
common-amplification system or increase HD Radio broadcasting power to the
proposed -10dB when needed.
“The HPX
Series places field-proven Harris technology in a new ground-up design to offer
radio broadcasters the most watts per dollar of any radio broadcast transmitter
on the market today,” said Tim Thorsteinson, president of Harris Broadcast
Communications. “The inclusion of our world-class FlexStar technology
gives broadcasters a robust, field-upgradeable transmission platform that will
reliably transmit one or multiple high-quality audio program streams over the
air for years to come, while keeping transmission costs to a minimum.”
HPX
transmitters come standard with the Harris FlexStar HDX-100 exciter. When
used in HD Radio common-amplification broadcast applications, HPX transmitters
are further augmented using the FlexStar family of HD Radio products, including
the company’s FlexStar HDE-200 Exporter introduced at NAB2008 in April.
The HDE-200 exporter includes remote and front-panel metering and monitoring
features and an internal GPS module, as well as options for profanity delay,
diversity delay and an Arbitron People Meter to help reduce the cost of
equipment upstream.
The
complete FlexStar range, which also includes the HDE-100 advanced services
importer, supports delivery of multiple HD Radio program streams over a single,
dedicated IP connection — ideal for broadcasters who currently operate or plan
to upgrade to an HD Radio multicasting configuration.
Transmitter
control options include an advanced control system that supports TCP/IP
connectivity for WEB access, SNMP communications and IP-based control and
monitoring. A single controller is capable of operating two HPX transmitters
and the combiner in dual combined or redundant backup modes.
All HPX
transmitters utilize the same internal components, from the highest power
common-amplification systems to the lowest power analog FM systems. All
transmitters feature field-proven Harris Platinum Z solid-state IPA modules and
Harris ZX series switching power supplies in a dual-redundant configuration,
which are front-panel accessible and hot-swappable to allow ease of service and
simplify spares inventory.
