About

Nautel is a manufacturer specializing in the design and production of AM and FM broadcast transmitters. Building on its pioneering experience in solid-state transmitters, the company has developed recognized expertise in the sector. Its product range covers a wide spectrum of needs, from compact transmitters like the J1000, ideal for mobile backup applications, to the high-power modular systems of the NX Series, which can be combined to achieve power outputs of up to 2 megawatts. Innovation is a central focus for Nautel, which was the first to integrate all HD Radio™ components inside the transmitter. The company's products are designed for energy efficiency, with models achieving 90% efficiency and incorporating MDCL power-saving technology. Nautel transmitters are also compatible with modern digital transmission modes, including HD Radio® and all DRM modes, and feature an Advanced User Interface (AUI) for full remote access and control.

Émetteur AM compact Nautel J1000

J1000

Le J1000 est un émetteur AM compact de 1000 W conçu pour la flexibilité et la fonctionnalité. Il dispose d'une architecture redondante, d'un changement de fréquence simple et est adapté comme solution de secours mobile grâce à sa taille compacte et sa conception légère.

The Nautel J1000 transmitter is an AM solution that provides excellent functionality in a compact package. It operates over a power range of 10 to 1100 watts, with advanced PDM modulation correction for low distortion. Its Direct Digital Synthesis (DDS) technology ensures a pure and stable RF carrier frequency, which can be interfaced with a GPS reference for synchronous operation. The J1000's redundant architecture is a key feature, utilizing two independent 500-watt power modules for enhanced reliability. Its compact, 19-inch rack-mountable design, combined with a simple frequency change procedure, makes it an ideal choice for use as a mobile backup transmitter or for applications requiring quick frequency changes. The unit also includes a built-in scheduler to program preset RF power levels, which is useful for "day timer" applications.
Its compact size, lightweight design, and simple frequency change capability make it an ideal solution for a mobile backup transmitter.
The J1000 operates over a power range from 10 watts to 1100 watts.
Yes, it can be interfaced with an external GPS reference clock signal for synchronous operation.
Émetteur AM haute puissance Nautel NX Series

NX Series

La série NX est une gamme d'émetteurs AM à semi-conducteurs, modernes et numériques, offrant une haute efficacité. Les modèles vont de 1 kW à 400 kW en unités autonomes et peuvent être combinés pour atteindre jusqu'à 2 MW, prenant en charge les modes analogique, HD Radio® et DRM.

Nautel's NX Series represents an advanced generation of high-power AM transmitters designed for efficiency, reliability, and digital performance. These transmitters are distinguished by an efficiency of 90% for models 100 kW and above, significantly reducing operating costs and environmental impact. The series includes MDCL power-saving technology as a standard feature. A key characteristic is the award-winning Advanced User Interface (AUI), which provides 100% remote web access and control, along with built-in instrumentation like RF and audio spectrum analyzers. Designed to be the industry's best digital transmitters, NX models use AM precorrection and 1.8 MHz direct digital modulation for high linearity. They are tri-mode, compatible with analog, all DRM modes, and HD Radio® transmission. The range extends from new compact low-power models (NX1, NX2.5) to high-power systems up to 400 kW, which can be combined to achieve 2 MW.
Models of 100 kW and above achieve 90% efficiency.
The NX Series is tri-mode, supporting analog, all DRM modes, and HD Radio® transmissions.
Yes, they offer 100% remote web access to the Advanced User Interface (AUI) for full monitoring and control.
MDCL (Modulation-Dependent Carrier Level) is a power-saving technology pre-installed as software to reduce energy costs by adjusting the carrier level based on modulation.

Services

Système de combinaison haute puissance Nautel pour émetteurs NX Series

Services d'intégration

Nautel propose des services d'intégration pour ses systèmes de haute puissance, permettant de combiner plusieurs émetteurs de la série NX pour atteindre des puissances de sortie allant jusqu'à 2 MW.

Nautel's integration services are designed for very high-power broadcasting deployments. By using Nautel's NXC combiners, it is possible to configure systems that combine two to five individual NX Series transmitters. This process allows for achieving power outputs of up to 2 megawatts. The service ensures that the NXC combiners integrate seamlessly with the NX Series control system, providing top-level Advanced User Interface (AUI) functionality for overall system control. This includes managing automatic switching, allowing the combined output or individual transmitter outputs to be directed to the antenna or a test load as required for operations. The combiners are also provisioned with built-in reject load modules.
Configurations with outputs of up to 2 MW can be achieved by combining NX Series transmitters.
Nautel uses its NXC combiners, which can combine two to five transmitters, to create high-power systems.
