The marKoni High Power DH Line is definitely the top-class equipment manufactured by Telsat.

These transmitters provide brilliant performances using a simple and reliable architecture to reach very high power levels, by connecting in parallel 3KW or 5KW modules.
Each of these modules is completely independent, so it can be used in standalone in emergencies or for network reconfigurations.

The use of high-performance heatsinks and the high efficiency of active devices allows a remarkable weight decrease, making transport, installation and management simpler. Effective software algorithms protect the equipment from any cause of breakdown.
The output power is dynamically decreased to conservative values in case of environmental overheating, or reflected power from the antenna system.

The internal combiners loads are dimensioned to work indefinitely, even in unbalancing conditions thus ensuring a continuous service, without signal interruptions.

The Master Control Unit of the transmitters oversees all the general parameters of each individual component (exciters, change over systems, amplifiers, etc.), maintaining the same management characteristics of the marKoni low and medium power lines, granting an important uniformity, which delivers to the Users the maximum comfort and familiarity with all the marKoni products.

Through the very User's friendly touch screen interface it is possible to check or change the complete system parameters. All these information can be also managed remotely by the network interface on the back panel, otherwise even locally by using the Ethernet connector on the front panel.

In the Dual Driver configuration the Master Control Unit directly manages the Exciters, the coaxial switch and distributes the base band signal.

The extensive use of high-level Digital Signal Processing gives to marKoni unique features in the audio broadcasting world.
The native AES/EBU input module guarantees pure digital quality avoiding the conversion from an analogue source. The presence of the traditional L+R input assures as well top performances even with standard analogue audio.

The FM modulation is implemented by an innovative direct-RF synthesis algorithm with sub-Hz accuracy onto an FPGA-based digital processing core.
The result is a frequency-agile transmitter with immediate installation procedure, which allows operators to broadcast their audio content with excellent purity and maximum reliability.

marKoni transmitters can be locked to the GPS time/ frequency reference signal for exact carrier allocation and Synchro FM operation, a promising band-efficient method of operating adjacent FM transmitters on the same RF frequency, after aligning all the RF and audio parameters of the transmission.

The result is a clearly improved listener's reception in the overlapping signal area, extending the coverage to shadow areas, normally characterized by inter-channel interference.

A typical application of this iso-frequency approach is the coverage of branches of highways, allowing car radio receivers to keep tuning the same carrier while driving, without the annoying effect of black spots along the road.

The pure digital audio sensation that marKoni creates is obtained thanks to a revolutionary Soft Limiter, which avoids audio intermodulation peaks, while safeguarding the integrity of the whole input dynamic range, with the use of accurate signal processing that allows high full-band stereo separation and extreme signal-to-noise ratio.

The units come with a full-option outfit: analogue and digital audio, analogue MPX and additional wideband SCA and IP inputs, embedded RDS Generator and Digital Stereo Coder and Web/SNMP remote control.
