- Main Features:
- PROVEN NX HERITAGE
- With over 40 megawatts of AM power deployed globally, the NX Series is field‑proven in demanding broadcast environments around the world
- Five generations of transmitter design and tens of millions of operating hours have shaped an architecture known for spectral purity, efficiency, and long‑term reliability
- NX1 and NX2.5 inherit that legacy, bringing NX‑class performance to low‑power broadcasters who have traditionally been limited to basic transmitter designs - DESIGNED FOR DIGITAL
- Industry’s first low‑power AM transmitters specifically designed to support digital transmission
- Advanced digital modulation, ultra‑linear design, and digital precorrection are built in, not added later
- Designed to support MA3 mode
- Enables FM‑comparable audio quality, multiple program streams, and metadata transmission such as song titles and station information
- Supports all current DRM modes and offers excellent program flexibility, allowing broadcasters to offer both AM and DRM services on a time of day basis - OPTIMIZED FOR LOW POWER
- Front-accessible RF Modules
- New power modules optimized for low power operation integrate an RF amplifier/modulator, delivering a nominal 250 W of carrier power per module
- Modules are hot-pluggable from the front for easy service
- Advanced Class‑D RF amplifier with four transistors offers superior efficiency and reliable performance - Switching Power Supplies
- Compact, titanium‑grade power supplies with 96% efficiency minimize energy consumption and thermal stress
- Modular, easily serviceable design enables quick replacement
- Serial communication provides detailed metering and alarms
- Supports real‑time monitoring, proactive maintenance, and enhanced operational reliability - MORE CONTROL | MORE SAVINGS | MORE FLEXIBILITY
- Easy On-air Serviceability
- All modules contribute equally to final output at all power and modulation levels
- Amplifier failure does not stress remaining modules or compromise spectral integrity
- Repair or replacement can be performed at any convenient time
- Brushless DC powered ball bearing fans mounted to the front of each power module
- Airflow remains unaffected by AC supply variations, ensuring cool operation and long-term reliability - Redundant Architecture
- Optional Standby Exciter
