Broadcast Electronics AM 1A – 1 kW Solid-State AM Transmitter

Product Description:
Trusted Efficiency and Broadcast Reliability

Broadcast Electronics AM 1A – 1 kW Solid-State AM Transmitter delivers proven reliability and high efficiency for continuous AM broadcast service. Compact, rugged, and fully solid-state, it provides 1 kW of clean RF power with outstanding linearity and low distortion – making it ideal for both main and backup transmission at professional AM stations.

Efficient Solid-State Power
Using rugged MOSFET amplification and modular power supply design, the AM 1A achieves better than 80% AC-to-RF efficiency. This reduces operating cost and heat output, ensuring dependable long-term performance with minimal maintenance.

Exceptional Audio Quality
A DSP-based modulator ensures precision control of carrier and sideband performance. The result is transparent, low-distortion sound that meets or exceeds international AM spectral standards. This transmitter is ideal for broadcasters requiring consistent modulation accuracy and clear, balanced audio across the full AM band.

Intelligent Control and Monitoring
Local and remote control options include TCP/IP, SNMP, and RS-232. The intuitive front-panel LCD interface provides real-time metering of forward power, modulation, PA current, and alarms – enabling engineers to manage the system confidently from anywhere.

Engineered for 24/7 Operation
With integrated protection for VSWR, over-temperature, and power overload, the AM 1A is built for continuous duty. Its robust cooling design and field-replaceable modules ensure consistent uptime even under harsh conditions.
