° 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 ÷ 25 W maximum output power continuously adjustable by external control. Ideal as stand-alone transmitter or versatile exciter for power amplifiers.

° Frequency agile. Instant internal (KE 20) or front panel (KE 20/C) frequency programmability with 10 KHz steps. No tuning or adjustments required.

° Digital stereo coder. High performances digital 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 (R/ option) with all parameters in internal optional board. Power output adjustment, on/off, alarms reset, Pfwd, Pref, frequency deviation measurement 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 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 oscillator. For more frequency stability the /HS option is available.

° Deviation limiter. Internal dynamic function limits the maximum frequency deviation according with international requirements (CCIR, FCC, etc...). This is to avoid adjacent channels invasion in case of accidental overmodulation without reducing the modulation quality.

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

° Meters. forward power, reflected power, frequency deviation, internal power supply voltage, L & R levels are continously displayed by front panel meters.

° Adjustments and settings. Output power (PWR adj.), frequency deviation (DEV adj.), transmitting frequency (in KE 20/C), manual/remote function (in KE 20/R), mono/stereo function (in KE 20/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.

° High efficency switching mode power supply gives greater reliability and reduces the power consumption.

° Battery operation is also available as (/VDC) option.

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