One of the most robust and simple FM transmitter in the broadcasting world is the marKoni-A. One of the most widely used from broadcasters in the world.

Thanks to it being so easy to install and use, it is easy to use it at the site with just a few technical precaution.
Its modular internal structure allows for a fast maintenance and service. The transmitter can be built assembling different options as requested. Build your device as per your need and optimize costs!

A family of devices composed by MKRT-A models, with a range from 50 to 1500 Watt, available in single drive, dual drive or N+1 configurations for the maximum redundancy level. The philosophy of marKoni-A 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 simple 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 (optional) on the back panel.

The display board on the front panel can indicate and change frequency, forward and reflected power, amplifier temperature, modulation level, alarms level, emphasis, as well as enable control.

The rear panel contains XLR balanced inputs with input level controls, BNC for MPX output from internal stereo coder (if option is present), BNC for MPX input, 2xBNC for SCA operation.

There is also a DB9 for wired external control and a DB9 for serial RS485 remote control.

As far as audio performances are concerned, only one word is needed: "transparent". With a signal-to-noise ratio of 80dB, the whole dynamic of the modern digital audio sources are reproduced with high fidelity.

With a crosstalk of 60dB (with stereo option) there is no chance to "misunderstand" the source of the signals.

The RF output is via an N Female or 7/16” type connector.

The power amplifier is based on LDMOS devices. A fresh air tunnel through the transmitter keeps cool air running right through the heatsink.

The amplifier is protected from damage by temperature control systems and antenna fault (SWR) monitoring. There is an added control on reflected power and heatsink temperature, that is foldback thresholds that permits to stay on air at a reduced output power even if conditions are not optimal.

The switching-type power supply automatically adapts itself to any input voltage from 90 to 260V.
