RX-4 User’s Manual -- Version 1.01 BURK Technology

PRODUCT DESCRIPTION
This section of the manual features an overall description of the RX-4, physically and functionally,
including a set of technical specifications -- for the unit as a whole, and for each of its component
receivers. It concludes with keyed illustrations of the front and back panels.
RX-4 Features and Overview
The RX-4 integrates four modular receivers, designed and packaged to provide a complete single-unit
solution to the requirements of Emergency Alert System (EAS) applications. Though it has been
designed, along with the LX-4 audio switch, to be a companion to the Burk EúAúS unit, the RX-4 will
provide superior performance with any EAS equipment.
As its standard configuration the RX-4 features an AM receiver, two FM receivers, and a NOAA Weather
Radio (WX) receiver -- the most adaptable conformation for handling the range of EAS monitoring
assignments in a single, easily installed, convenient-to-use unit.
Beyond the essential robustness and quality of its design, materials, and workmanship, the RX-4 is
specifically geared toward EAS applications in the professional environment by virtue of the following
features:
•Digital tuning, which keeps the RX-4 receivers locked on frequency, and capable of meeting the strict
demands of EAS operations, where receiver drift can mean missed alerts. Furthermore, tuning
controls are located inside the unit, providing the user with protection against the casual or
inadvertent changes in tuning that could cause lapses in compliance.
•High-performance receivers, with superior overload protection, enable the unit to be used in high-RF
surroundings, and near transmitting equipment, without compromising signal sensitivity or output.
•Loop-through capability, that permits chaining of the receivers (within a single unit, or even among
separate units) in a “hot standby” mode, both for maximum backup and for automatic coverage when
an assigned source is off the air.
Before we proceed to discussing how to install the unit, please take a moment to examine the technical
specifications on the next page, and to familiarize yourself with the RX-4 controls, indicators, and
input/output connections, presented in the front- and back-panel illustrations that appear following.
