Suitable for digital audio. FM exciter of last generation fully compatible with digital audio. In la 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 au Even the musical quality of traditional analogic audio is emphasized.

0 ÷ 20 W maximum output power continuously adjustable by external control Ideal as stand-alone transmitter or versatile exciter for power amplifiers. 87.5 108.0 MHz. Instant internal (FT 20 K) or front panel (FT 20 K/C) frequency programmability with 10 KHz steps. No tuning or adjustments required.

High performances digital STEREO CODER BUILT-IN (/S option) with stereo separation (+- 65 dB) and signal/noise ratio (>= 80 dB) for a top sound quality.

Remote control Full remote control capability (/RC option) with all main parameters internal optional board. Power output adjustment, deviation adjustment, on/off alarms reset, Pfwd, Pref, frequency deviation measurement and alarms status are the main possibilities remote control function.

Top quality sound. The generated signal is characterized by an excellent signal/noise ratio an by negligible residual AM and FM.

All this guarantees 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 quartz. For more frequency stability the IHS option is available.

Deviation limiter. Limits the maximum frequency deviation to a value within the international requirements. This is to avoid adjacent channels invasion in case of accidental overmodulation without reduce the modulation quality.

Electronic protections in case of load mismatching (VSWR) or transmitting frequency e (LOCK) . Every alarm event is displayed by front panel LEDs and can be reseted by manual remote control.

Meters: output power, reflected power, frequency deviation, internal power supply voltage, L & and 19 kHz levels are continuosly displayed by front panel meters.

Adjustments and settings. Output power (PWR adj.), frequency deviation (DEV adj.), transmitting frequency (in FT 20 K/C), manual/remote function (in FT 20 K/RC), mono/stereo function (in FT 20 K/S) are front panel available for instant adjustment and setting.

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

Switching mode power supply. High efficiency switching mode power supply gives greater reliability and reduce the power consumption. Battery operation is also available as (NDC) option.

Meets or exceeds international standards for safety and electrical specifications.
