NX Low Power

Advanced User Interface (AUI)

Nautel’s transmitters to place enhanced control into the hands of engineers so that they could become more efficient in their work, whether they are local to the transmitter or remote, using the award-winning AUI.

Built-in commercial grade instrumentation can mean even more savings and helps you optimize your on-air signal. Advanced control features include:

• New dynamic RDS scrolling
• New oscilloscope instrumentation
• Unique MER instrumentation
• RF and audio spectrum analyzers
• Comprehensive monitoring and control to the sub-module level
• Extensive logging of all events
• SNMP support
• Email notifications

Power Saving MDCL

Exceptional efficiency and low maintenance overhead make these transmitters extremely cost effective to own and operate.

High efficiency means less energy is wasted as heat, which reduces cooling and ventilation costs. The resulting savings could amount to tens of thousands or even hundreds of thousands of dollars over the life of your transmitter depending on its size and your local power rates. Efficiency also results in the ability to reduce green house gas emissions by thousands of metric tons over the life of your NX transmitter.

NX transmitters come standard with free MDCL power saving technology as pre-installed software (i.e. not an optional circuit board).

Building the Industry’s Best Digital Transmitter

To design the industry’s best digital transmitter our engineers applied two guiding principles:

• First they designed a transmitter so linear that no pre-correction would be needed.
• Then they pushed the limits of transmitter design by adding the best digital pre-correction available.

NX transmitters achieve outstanding linearity by employing a unique six phase Direct Digital Modulation that is encoded at an unprecedented 1.8 mega-samples per second. NX Series pre-correction corrects for all primary forms of distortion which typically affect both analog and digital AM broadcasting.

Specific pre-correction techniques include:

• Envelope equalization
• AM-AM correction
• AM-PM correction

All pre-correction filters can be monitored from the front panel display. The result is an ultra linear digital broadcast transmitter design. The inherent linearity means that your NX transmitter is prepared for the future. Analog, all modes of DRM 30 or HD Radio^® are all supported today in this tri-mode design.

All-Digital AM

Specifically designed for digital operation, Nautel’s NX Series transmitters support All-Digital AM broadcasting, leveraging Xperi’s MA3 mode to deliver enhanced audio quality. These transmitters ensure precise spectral mask compliance and a high-quality in-band signal, essential for digital features such as rich metadata, which enhances the overall user experience.

Why Go All-Digital?

For AM stations, transitioning to all-digital broadcasting presents a significant opportunity to enhance signal quality and expand their listener base. With many AM stations already rebroadcasting on FM, going all-digital on the AM band allows these stations to deliver FM-like audio quality along with digital services such as Program Service Data (PSD) for scrolling text and Artist/Advertiser Experience image capabilities. This not only improves the listener experience but also makes the station more competitive by providing a clearer, more distinct sound and rich digital features compared to other stations still using analog. As a result, stations can attract a broader, more engaged audience while standing out in a crowded market.

Key Aspects:

• Superior Audio Quality: Comparable to or better than analog FM.
• Noise Immunity: More resistant to noise and interference than analog or hybrid digital AM.
• Data Services: Supports additional data services, including song titles, album art, station information, and multicasting.
• Compatibility: Receivable on existing HD Radio receivers.
• Regulatory Compliance: Requires notification and approval from the FCC.

Conservatively Engineered Building Block

The building block of the Low-power NX Series is an integrated RF amplifier/modulator with a carrier power capability of 250 W. These modules are hot‑pluggable from the front of the transmitter for easy service, and the advanced Class‑D RF amplifier, with four transistors, offers superior efficiency and reliable performance.
