FM (With Digital Modulator)

Telsat presents its own FM transmitters line: marKoni.

The philosophy of marKoni transmitters provides a high reliability granted by very robust power supplies and amplification circuits, realized with MOSFET that are able to guarantee excellent performances, with very high efficiency and consequent low heating of all components.
Through the very User's friendly touch screen interface it is possible to check or change the complete system parameters. All this 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.
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.
marKoni is a synonymous of environmental sustainability (over 90% of the construction materials are recyclable).
marKoni the future is here!
