FM SOLID STATE TRANSMITTER/LCD
(87.5 –
108 MHz / Digital Ready)
• 1.000Watt, 1.500Watt 2.000Watt,
3.000Watt, and 5.000Watt output
power in continuous service: all
parts used in these amplifiers are
oversized to guarantee the full
power 24/24 h even in hard
environmental conditions.
• Z-Matcher System for all 87.5 -
108 MHz. Improved with Z-Matcher
Technology for best amplifier
efficiencies, minimizes phase error
and increasing system reliability.
The frequency of these amplifiers
can be easily field tuned from 87.5
MHz to 108 MHz without any parts
modification.
• High Quality Power Mosfets. With
Cold FET Technology, The amplifier
uses strong and reliable LDMOS
Mosfet, widely used in the
broadcast field, that assure long
life and low maintenance costs.
• Adjustable output power. allows
the adjustment of output power
simply varying the input one and/or
by LCD Menu Sub System.
• Frequency agile. Instant direct
frequency programability from LCD
Sub Menu with 10KHz steps. No
tuning or adjustments required.
• Digital stereo coder. High
performances digital STEREO CODER
BUILT-IN (optional) with stereo
separation (≥ 65dB) and
signal/noise ratio (≥ 80 dB)
for a top sound quality.
• 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
uProcessor Controlled Digital Phase
Locked Loop circuit with low drift
quartz reference.
• Deviation limiter. Internal
dynamic function limits the maximum
frequency deviation according with
the international requirements
(CCIR, FCC, etc…). This is to avoid
adjacent channels invasion in case
of accidental overmodulation
without reducing the modulation
quality.
• LCD Menu Metering/Indicators:
Working Frequency, Forward Power,
Reflected Power, Frequency
Deviation, Internal Power Supply
Voltage and Current, Heat Sink
Temperature, Input Audio L & R
levels are displayed by front panel
LCD Display.
• uProcessor Controlled protections
assures an affordable and stable
operation protecting units against
major fault conditions. Every alarm
event is displayed by front panel
LEDs and/or LCD Menu and can be
reseted by manual control and/or
automatic reset control.
• Full metering. All the main
parameters of the amplifiers are
front panel LCD displayed by a
complete measurement system.
• Soft-start circuit control: the
gradual insertion of power supply
eliminate transient problems during
start-up.
• Forced air cooling. An oversized
cooling system guarantees regular
functioning and long life for the
cavity/tube set even in hard
environmental places.
• Meets or exceeds international
standards for safety and electrical
specifications.
