MAIN DESCRIPTION
Falcon XT is a Digital Audio Processor, a Stereo Generator and an RDS encoder, all in a single device, specifically
designed for the market of broadcast FM radio, Web Radio and Satellite.
The Falcon XT audio processor is based on DSP dedicated technology, with a 5-band audio processing architecture.
The Stereo Generator is fully digital, and can create a perfect Multiplex signal. Falcon XT, can be completed with a RDS
Encoder also fully digital DSP-based. Falcon XT allows to create your own soundprint, unique and unmistakable.
Be recognized today in the crowded world of broadcasters in FM, DVB-T or in the boundless world of the web has now
become very complicated, in a market where competition does not forgive mistakes. If the broadcaster does not want to
have the same soundprint of all radio stations, Falcon XT is the tools that stand out in this tangle of media.
Falcon XT provides the broadcaster even more demanding, extremely sophisticated audio features and high-level
standard: 5-band control compression, dual-band power AGC, three-band EQ and Brightness control. The parameterized
Stereo Enhancer command provide to the radio station sound, the spacing effect and large stereo horizon openings. The
control of the phases of mono audio signals, makes the voice sound more natural, the Expander control allows to
minimize the background or unwanted noise, while the Overdrive and the SuperBass dealing to make the sound more
important on low and very low frequencies, creating an impressive effect of loudness. In addition, the SuperBass
Harmonizer controls the distortion of the bass sound/low frequency, compared to their clipping, creating a sound impact
unmistakable, increasing the energy transmitted by the low frequency and making listening much more pleasant than
other audio processors. The two distinct Final Limiter drive, one broadband and one dedicated only to low frequencies,
maximize the presence of the sound, always maintaining a pleasant audio listening. Falcon XT makes the sound of any
single broadcaster unique, without creating a sound too artificially colored, that in time could be confused and become
tiring to be listen to.
The soundprint of each broadcaster can be created from one of ten preset audio files already on Falcon XT, from rock to
classical, country, talk show, or preset audio while preserving the original sound, enhance the character and the unique
details. It is possible to recall a preset using ASCII protocol serial / ethernet port or via GPIn logic state.
The Composite Clipper installed in the Stereo Generator provides the highest level of modulation, while the 'MPX Power
Control allow to use the processor in full compliance with the ITU-R BS.412 about a density reduction while maintaining
the same level of deviation. In order to calibrate and set up correctly the audio network, a digital tone generator with
variable sample frequency and amplitude is available on Analog, Digital and MPX outputs.
The Falcon XT front panel has two large LCD displays, the first LCD shows the whole process input and output from the
audio processor, including the amount of intervention on each single compressor band, the limiting introduced by the
multiband limiter, the AGC level, input and output levels of audio sources analog, digital and MPX. The second display
shows all Falcon XT parameters such as preset on the air, RDS station name, GP In and GP Out status. Again on the
front panel there is a headphone output for monitoring the audio process introduced by the Falcon XT. So it’s simple to
hear the difference between the original audio and the processed one.
The internal RDS encoder available as an option, provides two DataSet, each with a wide range of services including
static programmable PS 60 messages, 16 RadioText messages, Alternative Frequency (AF) to receive the best
frequency as a function of 'coverage area, the Traffic Program (TP) / Traffic Announcement (TA) to listen to traffic
information and functions such as EON, M/S, DI, CT, PI, PTY, PIN. The switching between the DataSet can occur by
serial commands, GPIO or TCP/IP from a radio automation system. The RDS encoder complies with UECP SPB490.
The connectivity of Falcon XT is complete and manifold. The rear panel contains XLR connectors for connection of the
inputs and outputs in analog and digital AES/EBU. As regards the part MPX are available two outputs individually
buffered and independent for the signal MPX+RDS, plus two additional inputs AUX (SCA) with different functionality. An
AUX input (SCA) expressly intended use of external RDS encoder, while a second input is able to switch the audio from
another processor MPX to create a subnet managed by the automation system. All outputs are equipped with hardware
bypass in case of fault of the apparatus.
For remote connections are available an Ethernet TCP/IP port, a RS232 serial port, a USB port and a connection port
GPIO with optocouplers and open collector representing the operating states and alarms. Falcon XT can be controlled
remotely via Windows-based client software or through a common http pages thanks to the web server. Universal power
supply 90-264Vac 47-63Hz to operate in any region of the world Falcon XT occupies 1 rack unit 19 "

2 SAFETY WARNINGS
The installation and servicing instructions in this manual are for use by qualified personnel only.
-
Read All Instructions. All safety and operating instructions must be read before operating the product. They also
must be retained for future reference, as it contains a number of useful hints for determining the best combination of
equipment settings for Yr particular application.
-
Heed All Warnings. All warnings on the product and those listed in the operating instructions must be adhered to.
-
Heat. This product must be situated away from any heat sources such as radiators or other products (including
power amplifiers or transmitters) that produce heat.
-
Power Sources. This product must be operated from the type of power source indicated on the marking label and in
the installation instructions. If you are not sure of the type of power supplied to your facility, consult your local power
company. Make sure the AC main voltage corresponds to that indicated in the technical specifications. If a different
voltage (ex. 110/115 VAC) is available, open the equipment closure and set the voltage switch on the main supply
circuit, located behind the AC socket
-
Power Cord Protection. Power supply cords must be routed so that they are not likely to be walked on nor pinched
by items placed upon or against them. Pay particular attention to the cords at AC wall plugs and convenience
receptacles, and at the point where the cord plugs into the product
-
Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When
a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
-
Lightning. For added protection for this product during a lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the AC wall outlet and the audio connections. This will prevent damage to the
product due to lightning and power line surges
-
Installation. Configuration and installation should only be carried out by a competent installation engineer
-
Cabling. Using high quality wires, well protected. Make sure the cable integrity.
This symbol alerts you to the presence of dangerous voltage inside the closure – voltage which
may be sufficien
t to constitute a risk of shock. Do not perform any servicing other than that
contained in the operating instructions. Refer all servicing to qualified personnel
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
Do not change the voltage setting or replace the mains fuse without first turning the unit off
and unplugging the mains cord
Make sure the AC main voltage corresponds to that indicated in the technical specifications.
THIS APPARATUS MUST BE EARTHED !
To avoid risk of fire use the correct value fuse, as indicated on the label stuck on the right
side of the unit.
This apparatus uses a single pole mains switch and does therefore not separate the unit
completely from the mains power. To completely separate from mains power (in the event of
danger) unplug mains power cord. As the MAINS plug is the disconnect device, the
disconnect device shall remain readily operable.
