PFG NEXT SERIES
Efficiency, versatility and simplicity at the highest levels
The PFG NEXT series of modular FM transmitters are the best combination of efficiency, versatility and simplicity thanks to the state-of-the-art technology present and their innovative design. Thanks to the various available configurations, these transmitters can grant the best solution matching network requirements and granting maximum robustness and highest efficiency operation at the very competitive price. With the introduction of an intelligent Automatic Current Sharing Technology, the PFG NEXT can work in the worst fault conditions whilst maintaining the highest output power everseen. Moreover thanks to the Hot Swappable Technology maintenance cost and time are drastically reduced.

GreenRF technology is the evolution of the COLD-FET technology adopted by DB for its transmitters. With the use of special high performance LDMOS transistors, this technology brings innumerable advantages, among which a high RF efficiency (> 70%), high reliability and safety, less heating and AC power consumption, which lead to a very longer transmission life.
MSE (Magnetic Sound Enhancer) is the DB technology which consists of a magnetic barrier that protects the VCO (Voltage Controlled Oscillator), the heart of the FM modulator, significantly increasing the sound quality.
Automatic Current Sharing technology consists of an automatic current balancing system and a perfect load distribution, creating optimal power operating conditions that lead to maximum redundancy. As a result, the output power loss in the event of a power failure is extremely low and, in a dual power supply configuration, the power loss in the event of a power unit failure is less than 35%.
With the Hot Swap System present in the transmitters it is possible to carry out maintenance on the power supplies with the machine on and on the air in less than 5 minutes as well as for the amplifiers in modular transmitters. Even the cooling fans can be removed, cleaned or replaced in just 5 minutes thanks to their placement outside the machine.
Responsive Cooling System is an optimized and highly efficient cooling system. Thanks to the ability to react to changes in temperature of the transmitter or the environment, the system guarantees correct operation and optimal performance even in extreme climatic conditions or in the presence of high temperatures. The cooling system keeps the heat sink temperature at optimum levels.
Extremely detailed and intuitive web interface with all main parameters fully controllable and adjustable. Ability to remotely check the status of the transmitter and set malfunction alerts via e-mail and/or trap for prompt intervention. Firmware that can also be updated remotely and an easy back-up system for personal data and configuration.
Thanks to its research and development center, DB is constantly working to improve the design of its products so that the interaction between user and devices is always easier, more intuitive and maintenance faster and cheaper. The clever placement with direct access of the fans in the back and outside of the transmitters and amplifiers and that of the power units with easy access are the result. Such as the combination of latest generation RF combiner technology with ultracompact unbalancing dummy loads and a smart intercommunication interface between RF modules, drivers, and Logical Control System.
Stereo Generator: high performance built-in digital stereo encoder that provides separation typical > 65dB.
Device equipped with VSWR (Voltage Standing Wave Ratio) 65:1 built-in protection to prevent load mismatch failures.
