° Graphic LCD Panel. Revolutionary new generation 60 W FM transmitter or exciter with graphic LCD front panel full control and measurements. Front panel instant frequency programmability, RF power settings, audio settings, deviation controls, alarms status are only the main facilities available in the graphic display.

° Suitable for digital audio. FM exciter of latest generation fully compatible with digital audio. In fact the amplitude and group delay linearity extended to the sub-sonic frequencies band to avoid the low-frequencies overmodulation and phase distortion exalts the musical quality of digital audio. Even the musical quality of traditional analog audio is emphasized.

° 0 ÷ 60 W maximum output power continuously adjustable from front panel graphic menu selector. Ideal as stand-alone transmitter or versatile exciter for power amplifiers.

° 87.5 ÷ 108 MHz. Instant frequency programmability using the front panel graphic display menu. No tuning or adjustments required.

° Stereo coder. High performances digital built-in stereo coder (/S option) with stereo separation (> 65 dB) and signal/noise ratio ( > 80 dB) for a top sound quality.

° Remote control. Full remote control capability thanks to the microprocessor on the front panel control board: power output adjustment, deviation adjustment, general on/off, alarm reset, forward and reverse power measure, frequency deviation measure and alarm status are the main possibilities of remote control function.

° Top quality sound. The modulated signal is characterized by an excellent signal/noise ratio and by negligible residual AM: all this for the best quality of the broadcast signal.

° High frequency stability in short and long terms is assured by Digital Phase Locked Loop circuit with low drift oscillator. For more frequency stability the /HS option is available.

° Deviation limiter. A CCIR standard deviation limiter limits the maximum frequency deviation meeting the international requirement in order to avoid adjacent channels invasion in case of accidental overmodulation: all this without affecting the audio modulation quality.

° Electronic protections automatically protect the equipment in case of load mismatching (VSWR) or transmitting frequency error (LOCK) or overtemperature (TEMP). Every alarm event is displayed by a front panel general ALARM led and more details are available using the front panel display menu (type of alarm, date and time of the alarm, etc…).

° Output low pass filter. It assures a pure RF spectrum, according to the international requirements.

° Power supply. High efficiency switching mode power supply gives greater reliability and reduces the power consumption. Battery operation is also available as (/VDC-24) option.

° Meets or exceeds the international standards for safety and electrical specifications.
