STX FM Transmitter Series
The STX continues the legacy of reliable, efficient, and performance-leading FM
transmitters from Broadcast Electronics. STX has been designed for high efficiency to
lower operating costs, world-class audio performance, maximum reliability and uptime, simplified and fast field repair, built-in redundancy, and the flexibility to support
continued technological updates over time.
The Best Audio Quality—Ultimate Reliability
Broadcast Electronics STX line of transmitters are designed to deliver a highperformance, cost-effective solution with models from 60 W to 20 kW. Leveraging the
highly efficient and compact RF technology of the latest ruggedized LDMOS RF devices
the STX provides the efficiency, compactness, and reliability you have come to expect.
We didn’t stop there, drawing from BE’s decades of providing the best-sounding FM
exciter on the market, we incorporated a digital direct-to-channel FM modulator and
ultra-reliable highly efficient hot-pluggable power supplies to deliver the
maintainability and robustness our customers have come to expect with the
performance and reliability BE is known for.
STX’s powerful control system provides extensive monitoring, logging, and control
capabilities with fast-acting protection for maximum reliability. A front panel LCD
screen, navigation buttons, and bright LED indicators allow easy review, setup, and
diagnostics. The RJ-45 port allows you to connect to the intuitive and powerful GUI and
SNMP from anywhere in the world. The standard parallel GPI/O interface provides
connectivity to a traditional remote-control system. 

Flexible options — software enabled
BE knows that in the fast-paced and evolving world of broadcast radio, the adage—the
only constant is change—holds. You need to invest in cost-effective tools for today but
maintain the flexibility to expand your system when things change tomorrow—all without ripping things out and starting over. The STX supports all analog and digital FM
Radio standards such as Analog FM, HD Radio®, DRM+ and emerging technologies.
You bring the content; we will help you deliver it to your audience cost-effectively!

Digital Modulator—The Heart of the Transmitter
Building on BE’s long legacy of superior-sounding FM exciters,
STX continues the tradition with a state-of-the-art Digital Direct
to Channel (DTC) modulator of unrivaled precision and sonic
clarity inside every transmitter.

The STXe is a digital exciter that can produce the best AES audio
but is also capable of broadcasting in HD or DRM+. The STXe
series of exciters include as digital stereo generator and an RDS
generator and multi-program inputs with a silence sensor.

Advanced Monitor and Control Capability
Every STX includes a powerful yet simple-to-use browser-based HTML-5 graphical user interface for control and monitoring of
the transmitter anywhere in the world. Extensive TCP/IP network connectivity via integrated RJ-45 connection allows the
transmitter to be securely connected to any IP network.
Integrated multiuser multilevel password protection ensures only
authorized operation on your network.

STX also supports a robust SNMP level 3 – (Simple Network
Management Protocol) interface for easy connection with a wide
array of powerful software network manager systems and
popular transmitter remote controls. The entire transmission
system can be controlled and monitored using the standard
published MIB protocols.
STX provides a comprehensive event log that captures all
transmitter-related activities, operations, and faults storing the
5000 most recent activities. This allows for detailed diagnostics
and simplified routine maintenance.
Remote Monitor and Control interfaces supported include:
• Popular parallel interface to panels and legacy remotecontrol systems
• Automated Alarms and notifications via Email or SMS text
• SNMP connectivity for alerts, monitoring, and control
• Web GUI via ethernet network connection RJ-45 (10/100Base-T) with TCP/IP protocol

Amplifier Design Provides Robust and Efficient Operation

STX employs LDMOS-power amplifier device technology coupled with innovative amplifier design to provide robust & efficient
analog and HD Radio operation. The STX controller constantly monitors the power supplies and RF amplifiers to automatically
operate the system at the desired power, efficiency and reliability.
Redundant rugged amplifiers and low-loss combiners protect against lightning, antenna system shorts, and high VSWR to keep
you on-air. These innovations reduce operating and maintenance costs, which provide a low total cost of ownership over the life
of the transmitter - maximizing your investment.

STX Rock Solid Reliability and Great Sounding Audio Scalable to 20kW
The Broadcast Electronics STX family of FM transmitters has been intelligently designed to offer the perfect combination of
audio quality, reliability, redundancy, serviceability, and efficiency in a compact design. Each transmitter is crafted with superior
