FT 1000

FT 1000


1050 W maximum output power continuously adjustable by external control.Ideal as stand-alone transmitter or versatile exciter for power amplifiers.

87.5 ÷ 108 MHz. Instant internal or front panel ( /C option ) frequency programmability with 10 KHz steps. No tuning or adjustments required.

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

Audio processor. High performances built-in stereo audio processor (/P option) with wide range compression threshold and release time adjustments. Fully compatible with digital audio mixing consoles.

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

FSK IDer. FSK option makes the FT transmitter series fully compatible with FCC automatic identification system.

Top quality sound. The generated 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 quartz. For better frequency stability the /HS 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 over modulation.

Electronic protections: in event of overvoltage (O.V.P.) or transmitting frequency error (LOCK) or mismatching (VSWR) or overtemperature (TEMP) the power output is automatically reduced to keep your station on the air. Every alarm event is displayed by front panel LEDs.

Meters: forward power, reflected power, frequency deviation, all internal mains power supply voltages, L & R, MPX levels are continuosly displayed by front panel meters.

Adjustments and settings. Output power (PWR adj.), frequency deviation (DEV adj.), transmitting frequency (with /C option), compression threshold and level together with release time (with /P option), manual/remote function (with /P option), mono/stereo function (with /S option) are front panel available for instant adjustment and setting.

Switching mode power supply. High efficiency switching mode power supply gives greater reliability and reduce the power consumption.

48 Vdc battery operation is also available as option (/VDC-48).

Meets or exceeds international standards for safety and electrical specifications.
