INTRODUCTION
INTRODUCTION
Congratulations on your purchase of the Falcon 50. The Axel Technology design team is confident you will
enjoy the outstanding performance of that processor for many years. In case you are interested in technical
details, what follows is a brief outline of some of the key technologies in your new processor.
A brief overview
Relying on Axel Technology’s extensive know-how in audio processing techniques, the Falcon 50 has been
designed and built using a new approach that incorporates the most up-to-date components and
technologies. Its efficient design allows the Falcon 50 to produce top-level results in a cost-effective way.
The largest control set allows you to paint a truly unique and competitive on-air sound: from detailed and flat
to heavy and loud. Its exceptional audio quality is maintained even at extreme settings.
The largest connection capabilities
Whether your audio system contains analog, digital or both formats, the Falcon 50 can be configured to fit in
perfectly. A sophisticated module allows flexible switching between inputs, e.g. for emergency purpose.
Fail-safe operation is assured by an internal bypass on all the audio and MPX I/O circuits.
Two Composite Baseband Outputs are provided, each with independent level control. The MPX clipping
stage is user-enable and adjustable. MPX power can be limited accordingly to ITU R-BS 412 Specification.
Two serial RS232 ports, an USB port and a TCP/IP Ethernet connection (the latter available as an option)
permit remote control and monitoring from almost any location through the use of a standard PC and the
dedicated control software which comes with the unit.
User-friendly controls
Falcon 50 set-up is quick and easy, thanks to a wizard based on less/more controls. User-configurable
remote control functions (including preset programming) are available through optocoupled inputs. For more
convenience, a complete day-part automation is also completely self-contained.
Control from anywhere
The Falcon 50 can be remotely controlled, either from a locally attached computer, or from anywhere in the
world.
There are many ways to do this.
- Using Falcon 50’s IP connection or modem connection you can control processor from anywhere in the
world using the provided remote Control Software.
- Falcon 50’s serial and USB interfaces allow you to connect any PC running the provided remote Control
Software.
- Falcon50’s programmable TTL inputs give you six “contact closure” inputs that can be used to control
certain functions, like ‘switch audio input’ or ‘change audio curve’.
State-of-art circuitation and plenty of headroom
Falcon 50’s analog and digital audio input and output circuits are state-of-the-art for high quality, low noise
and low distortion audio. The processor’s levels on analog input assure plenty of headroom for all
applications without the need for audio limiters. Professional quality AES/EBU digital audio input and output,
with internal high-quality rate converters are standard.

INTRODUCTION
ENG
Built-in automatic audio changeover
The Falcon 50 features two audio inputs: analog and digital.
The selection between inputs may be achieved manually or the programme source may be forced to either
input Analog or input Digital by activating one of six GP Input, accordingly to Source Selection menu.
The Falcon 50 also incoporates an audio detector stage, which can be used to automatically select between
two identical stereo programme paths (Analog or Digital), in the event the main program runs underthreshold (set at – 35 dB), extinguishes or the difference on levels between Left and Right channels exceeds
20 dB.
Once the Falcon 50 has switched from Main to Stand-by input, the Main input may be kept monitored till the
Main audio input resumes. Also when Main audio appears, a settable time may be awaited before inverse
switching (from B to A) is performed.
Two versions available: ‘blind’ panel or double-LCD panel
The Falcon 50 comes in two versions. The LCD version is fitted with two large LCD screens, showing inputs
and output meters together with main settings indication, current processing curve, date and time.
When pressing the large Jog/Wheel, the left screen switch to the block diagram, thus allowing to configure
and set each working and configuration parameter. The right screen still keep to display the levels
associated to the processor stage You are browsing, so that the control on the emission is never missed.
The LCD front panel gives full access to each configuration and working parameters without need for
dedicated Pc Control software.
The ‘blind’ version is especially designed for those users, who only need to remotely control the processor
from the Pc, with no needs for local control from the front panel. On the front panel, however, some LEDs
show correct operation and possible Alarm status. An USB socket and a Headphone socket are also fitted
for easy connection, respectively, to a Pc or to a pair of headphones.

ENG
APPROACHING AN FM AUDIO PROCESSOR
An audio processor is a nonlinear process, that is, even if the ouput signal might be slightly more attractive in
respect to the input signal, it has surely more distortion respect to the input.
For this reason, always try to use the cleanest possible audio material to get the cleanest ouput audio and
remember that the correct adjustment of a multiband processor is a quite complicated task, so, don’t be
frustrated if after thirty minutes you still cannot get your sound.
Remember also that “extreme loudness” settings are well suited only for certain kinds of music (pop, disco,
rap…) while are awful for other kinds of music; so always adapt the processor to the format of your radio.
General settings often sound well with most music formats even if they have not the same loudness.
The output sound is always a trade-off between loudness distortion and cleaness and you must choose the
trade-off between them according your taste.
Another last tip is that you might avoid the use of high stereo expander levels expecially with low bitrate
MP3s; MPEG compression puts a lot of “trash” into the stereo image so, often, enhancing the stereo image
you could enhance just “MPEG noise” (a sort of “tingling” you may hear at medium-high frequencies).
Last recommendation is to use a good quality audio board with a “flat” output, that is no further bass or treble
equalization must be added. This is the only way you may expect to have a good peak control and a
satisfactory audio quality.

INSTALLATION CONSIDERATIONS
4 INSTALLATION CONSIDERATIONS
Installing the Falcon 50 requires a bit more than mounting it in the rack, connecting some cables, and then
putting it on the air.
Among the factors you should consider are:
1. Monitor Location. You should have a good location in which the system, once on the air, can be
monitored. We suggest a good tuner, with good reception, feeding a set of studio monitor speakers
to be sufficient. While car radio and other “typical listener situation” settings are important, they
should not be the main reference points.
2. Good, Clean Source Material. If you are using poor source material, or poor performing playback
equipment, you will not get maximum sonic benefit from your equipment. Anomalies that you
perceive to be processing problems, may be source problems that the processing is exaggerating!
Make sure that you start out with a good first step - good source material!
3. Mic Processing. This may appear trivial, but the perceived sound of “live” voices over the air can
change dramatically with different processing systems. Whatever the effect your on-air microphones
will probably change when you change your processing. If you utilize mic processing, you may have
to adjust it to suit the operation of the new processing system. Most announcers develop a “comfort
zone” with respect to the sound of their voice over the air. When that “comfort zone” is changed or
modified, the common response is that something is wrong. Mic processing can be a very important
part of your overall station sound.
4. Operating Levels. This is another simple area where trouble can develop. Make sure the input and
output levels of the processor are at the operating at the proper level within your system.
Equipment internal Clock is powered by a capacitor instead of a traditional battery. The capacitor keeps the
clock operating and protects the system memory to prevent the loss of stored programs during power failure
around one week long (depending on the environmental conditions). Capacity charge needs at least 30’ of
normal operation. Clock tolerance might amount to about 1 sec per day.
A correct installation and an optimum level setting are crucial for a good operating and the exploitation of all
the equipment capabilities. Please pay attention to all notes contained in the user manual.

ON/OFF Switch, AC MAINS FUSE AND AC POWER RECEPTACLE. main ON/OFF switch, the LED
inside switches on/off accordingly. An AC mains fuse is provided which disconnects the Falcon 50 from
the wall outlet’s AC power under fault conditions. If this fuse should “blow” for any reason, replace it
only with the same value fuse. If it blows a second time, please contact your Axel Technology dealer
for service.
Two fuses (one for spare) are contained in a small drawer close to the cord receptacle.
For 220/230 V AC the fuse is slo-blo 5x20mm rated at 315 mA T; for 110 V AC it is rated at 630 mA T
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;
unplug mains power cord.
Never operate the Falcon 50 with ungrounded outlets: plugging the processor into an
ungrounded outlet or defeating the ground pin, can create a potentially hazardous
condition. Axel Technology can not be held responsible for problems caused to Falcon
50 or any associated equipment with improper AC connection.

Where possible use balanced connections for the audio inputs and outputs to minimise noise pick-up. Avoid
running audio cables near to mains or lighting cables or thyristor dimmer units, power supplies etc. These
may cause audible hum and buzz. The use of low impedance sources significantly reduces interference pickup. Check the cables for correct wiring to avoid problems with phase reversal and unreliable connection.

18.4 NOTES ON AUDIO CABLES
As with all professional audio applications, utmost care should be taken with audio cabling for your Falcon
50. For all balanced audio cabling, only high-quality, shielded twisted-pair audio cables should be used,
mated to high-quality XLR connectors. With proper cabling techniques, long lengths can be used, but excess
cable should be avoided.
Unbalanced audio cable techniques can also be used with the Falcon 50; however, cable lengths should be
limited to less than 15 mt, less if in a high RF environment. Only high quality shielded audio cable and
connectors should be used.
18.5 DIGITAL AUDIO INPUT
The digital input features two connectors: coaxial and optic. Only one connector may be connected at a time
to avoid malfunctions (TOSLINK optical connector should be kept covered while not used).
XLR female connector is designed for AES/EBU sources (“professional standard” interface), while TOSLINK
connector is designed to carry S/PDIF signals (“consumer standard” interface).
The digital input automatically recognizes the digital format (AES/EBU, S/PDIF, etc.), the type of connection
(optic or coaxial) and can seamlessly handle 32KHz, 44.1KHz, 48KHz and 96KHz sample rates.
Coaxial input (on XLR) is transformer balanced, and so highly immune from external disturbances and noise
(EMI).

18.6 CONVERTING BETWEEN AES/EBU AND S/PDIF INTERFACES
There are a number of differences in the electrical characteristics of AES/EBU and S/PDIF
interfaces which in some cases can render them completely incompatible. Although the audio data
is the same in both AES/EBU and S/ PDIF interfaces, they are indeed different formats, at least in
their subcode. AES converted to coax is NOT S/PDIF, and S/PDIF converted to XLR balanced
is NOT AES.
For proper performance, AES/EBU input (XLR connector) should therefore not be used for
connection to consumer equipment providing S/PDIF format.
18.7 DIGITAL AUDIO OUTPUT
The digital output features two connectors: coaxial and optic. Only one connector may be connected at a
time to avoid malfunctions. Please keep the tos-link connector covered while not used.
The coaxial input (on XLR) is transformer balanced, and so highly immune from external disturbances and

‘SYNC IN’ or the clock recovered from the AES/EBU signal provided at the DIGITAL audio input.
18.9 FRONT HEADPHONE SOCKET
The Falcon 50 front panel contains a ¼” jack audio socket for connection to
monitoring headphones. The Headphone output will contain the same audio
content as provided by the Analog output on XLR connectors at the rear panel.
The Headphone volume is controlled from the Main screen of Pc control software
on the ‘Blind’ version, while it is controlled by the associated menu on the left
screen on the LCD version (see ‘headphone’ button on the Falcon 50 LCD front
panel). Headphone impedance should be 70 Ohms or higher.

As always, quality CAT-5 cabling should be used. A CAT5 cable is used to
connect the network port on the back of the Falcon 50 to a port on a switch, hub or
router. It is also possible to connect the Falcon 50 directly to a host computer's
ethernet port using a crossover cable. LAN connections are typically limited to 100
meters without a hub, router or switch.
When connecting the Falcon 50 to a computer directly (i.e.with no infrastructure),
you must use a crossed CAT-5 cable as shown in Figure. When connecting a
Falcon 50 to an infrastructure (hub, switch, router...), use a straight-through cable.
When powering-up the processor, the Falcon 50 Network interface needs 30
seconds or more for complete auto-setup and inizialization. During this period, no
communication with the Pc through the Lan will be possible.
The network interface will be unavailabile for the same period (at least 30
seconds) also when altering its IP address.
For Network Port configuration You will need to communicate with the processor via
RS232 or USB connection.

Inside the processor, a 100 ohm resistor connects the pins 4 and 5 to a +12V power supply. When nothing is
connected to the GPI input, the input voltage therefore is +12V.
Inside the processor, 470 ohm resistors also are inserted on series on each optoisolator anode (see
pins 1, 2, 3, 6, 7 and 8) for current limiting. Nominal current on optoisolators is 5 mA, while the max current is
10 mA.

19.8 MPX AND AUX CONNECTIONS (available only on FM version)
The AUX 1, AUX2 and AUX 3 inputs (BNC connector, 10 kΩ impedance) allow external signals (tipically
RDS) from external encoders to be injected on the MPX output of the processor.
The input gain of the injected signals may be set by means of J1, J2 and J3 jumpers to 0 dB or to – 20 dB.
Factory preset is - 20dB gain for AUX 1 and AUX 2, while AUX 3 is factory preset to 0 dB gain.
Anyway, gains may be altered to 0 dB (- 20 dB) by moving the respective Jumpers J1, J2 and J3 on the MPX
output board.
The processor can mix SCA signals of any frequency with its own MPX signal, as long as
the former are compatible with the composite stereo signal and RDS signal spectra.
The MPX OUT 1 and MPX OUT 2 (BNC connector) provide the FM composite signal + any RDS signal
(internally generated or injected from an external encoder) and SCA signal. MPX OUT 2 output can be
reconfigured in software as a Pilot Reference Output useful for RDS (RBDS) subcarrier generators that
require an external sync reference.
Two attenuation switches (fully configurable) are provided on the processor to deal with
changing RDS/SCA input signals. Using the attenuators (applied to the internally
sourced MPX signal) will reduce the overall level of the signal output from the processor.
See the Chapter (MPX OUTPUT calibration & Setup).
Remarks:
•
The stereo multiplex output level is adjusted by software. Factory preset is 0 dBm, i.e. approximately 2.2
Vpp.
•
The output impedance of the BNC jack is approximately 10 ohms sourced by an output driver capable to
drive 600 Ohm loads (typical). Maximum performance is achievable when using up to 10 meters of RG-58
cable. Alternatively, 75 Ohm cable may also used for short runs.
•
Contrary to Left / Right audio outputs, pre-emphasis is always present on the MPX output and you
can NOT disable it. Nevertheless, You may set the pre-emphasis time to 50 or 75μ sec.
•
•
•
The 19 kHz pilot phase and level may be adjusted via the control software.
MPX Out provide various reference tones consisting for easier transmitting chain set-up. To enable the
reference tone, see Pc control software operation
Each MPX output is individually buffered so that a short circuit on one output will not affect the other.
The SYNC OUT (BNC connector) outputs a 19KHz / 5Vpp square wave for external equipment
synchronization (i.e. RDS encoders). The Sync output must be enabled via the control software

MONITORING THE FALCON 50 FROM A ‘PDA’
ENG
20 MONITORING THE FALCON 50 FROM A ‘PDA’
The Falcon 50 comes with a free software to be installed on a PDA (Personal Digital Assistant) computer.
A PDA gives easy and immediate access to Falcon 50’s input and output levels and it can be used to switch
the curve currently aired and to import/export curves from/to a given location. For those reasons, the PDA
becomes an useful tool in particular when used with the processor in its ‘blind’ version. This way, one may
get I/O current status, alarm status and one can switch the curve at any time, with no need for a full-featured
computer.
The PDA may be connected either on the front USB socket, or on the rear USB socket of the Processor.
The application for the PDA is provided on the Installation CD ROM, in the PDA Software folder. Installation
software is on CAB format. A cabinet CAB file is a compressed file that holds all of the items necessary for
installing a program on your Pocket PC. Cab files are extremely portable because you do not need
Activesync in order to install a program on your Pocket PC. As long as the .cab file is on your device, then
you can perform the install.
Page 41
ENG
MONITORING THE FALCON 50 FROM A ‘PDA’
To install the software on the PDA, follow these istructions
Copy the .cab file (its name will look like Falcon50.arm.CAB) on Your Pc. Perhaps this file will be associated
to a compressed file icon, such as WinRar or WinZip starndard icons.
Step 1: First step is to copy the .cab file on your Pocket PC. If you have a memory card reader, you can
copy it to the card and insert it into your Pocket PC. If you simply download the .cab file from the Web site
www.axeltechnology.com you can get it that way. Alternatively, You may use the Activesync tool.
Step 2: Navigate to your My Documents folder on your Pocket PC and you'll see the .cab file listed.
Step 3: Tap the .cab file one time and it will install!
Step4: Run the software application on the PDA from Start - Programs.
Once installed and launched the Falcon 50 application, using the PDA keyboard, You may create a Login or
just type the Login password.
This way, You may easily access the default two pages
with all the level meters (see Fig 2).
Clicking with the PDA stylus the folder at the top right
corner (see picture) You can also enter the
Import/Export facility page (see Fig 3).

2.1
THE ‘COMPACT SKIN’ MODE
While the control software comes up, it will detect the actual resolution of the Pc monitor. If resolution is
better or equal to 1024 x 768 (XGA), the software opens by default at its max graphic quality and detail
(Extended Mode).
If lower, it automatically prompts in a more primitive graphic way called ‘COMPACT SKIN’ mode, which
opens the interface windows at a lower resolution, suitable for SVGA (800 x 600) Pc monitors.
Anyway, when using high-resolution monitors, the operator may always choose the Compact Skin mode
from the starting window by clicking the associated option on the window.
Once the program has started, it will resemble one of the following mask, according to the chosen display

MODEM CONNECTION EDITING
Choose ‘Modem’ in the Connection Type window.
First of all, select the serial port on the pc the modem is connected to.
The screen will also prompt for the Phone Number. Enter the number
that is to be dialed.
Type in the complete number. It is NOT acceptable to use hyphens or
dashes. Example, when dialing a listed number such as 241-3343, it
must be entered as 2413343.
If dialing out from a PBX system where a local line must be selected, enter the access number followed by a
comma, then the number to be dialed. For example, if you must dial 0 to get an outside line, you would enter
0, 2413343. The comma inserts a pause in the modem string and allows the outside line to be connected
before the actual number is dialed.
Keep the actual initialization string for the local modem which is prompted at the bottom field.
Note: the initialization string is based on standard AT commands. Please refer to the relevant
documentation for further details. For best operation, we highly suggest to use default string.
Once the desired number to dialed and the other data are entered, press the SAVE key. The new connection
will now be displayed in the Available Connections list field on the main mask. Press ESC (D) (or hit the ESC
key on Your keyboard) to leave without saving.
At the processor side, using a modem connected to its serial port MUST be enabled
from the Software. Refer to the COMMUNICATION screen.

REMOTE CONTROL VIA IP (ETHERNET CONNECTION) *
Type the IP address of processor to connect to in the IP field
on section (B)
The Falcon 50 may be given an IP address (with associated
Subnet mask) from the COMMUNICATION page of Navigation
Main Menu.
After having edited the connection, the Connect button will then
execute the connection, while ESC will discard the settings. Both buttons will afterwards close the dialogue
mask.
* the Falcon 50 TCP/IP interface is available as an option. For further information, contact Your local dealer.
Example for assigning an IP Address:
A Falcon 50 may be operated on a network where the following applies:
– The IP Addresses 192.168.1.0 to 192.168.1.100 have already been assigned
– The sub-network mask is 255.255.255.0
– The Falcon 50 should contain IP Address 192. 168.1.101
You can change at any time the actual Falcon 50 IP-address from the COMMUNICATION window
(accessible by the COMMUNICATION tab on the Navigator screen) – see associated Chapter.
The presence of a firewall on Yr local network could cut down the connection speed. If
You experience any lack of fluidity in the menu navigation, try to disable possible
software controls on IP streaming (such as ZoneAlarm) and/or choose the slowest
refresh rate of software screens (Ref to Preferences paragraph on next Chapter).
When powering-up the processor, the Falcon 50 Lan interface needs up to 30
seconds for complete auto-setup and inizialization.
During this period, no communication with the Pc through the Lan will be possible. For
the Ethenet Port configuration You always need to communicate with the processor via
RS232 or USB connection. The default IP Address of Falcon 50 Lan interface
(whenever installed) is 192.168.0.20, with Subnet Mask 255.255.255.0.

PASSWORDS & RIGHTS TO ACCESS THE PROCESSOR
6 PASSWORDS & RIGHTS TO ACCESS THE PROCESSOR
6.1
USER PROFILES
The Falcon 50 provides five levels of security, ranging from absolutely no access to any of the processing
adjustments and parameters to full access to all functions. These FIVE levels (each one having its own rights
associated) are indicated as Guest, Broadcaster, Advanced User, Technician and Administrator.
ADMINISTRATOR
Grants full access. All functions and parameters can be monitored and
adjusted from this level. Also, the Administrator is fully allowed to set
Processor password to grant or denies access to the other users (SYSTEM
page). Once this level is selected, be careful because you can make a good
mess of things.
TECHNICIAN
It provides the same access as Administrator Level, but with the exception of
the SYSTEM page (user access/rights management).
ADVANCED USER
It provides access to AUTOMATION and to AUDIO PROCESSOR blocks. The
Advanced User is therefore allowed to make processing (i.e. sound) changes
and to make scheduling changes. He/her is not allowed to modify Input/Output
signal levels.
BROADCASTER
It permits all processing parameters to be viewed but not adjusted. In addition,
the processing curve may be chosen among the available (preset) ones and
scheduled from the SCHEDULER page.
GUEST
It is the total “lockout” level. It allows the viewing of signal meter activity (audio
input level, band levels, etc) on the software screen but it provides no access
to all processing functions. This is a ‘very basic’ level, which can not be set
from the SYSTEM page.

CHANGING PASSWORDS FOR ACCESSING THE PROCESSOR
NOTES ON PASSWORDS
Passwords only provide security if you use them. Distribute passwords only to station
personnel only when they must have access to Falcon 50 functions.
If you change your passwords and forget them, the only way to gain access to the
processor is restoring the Falcon 50 to factory defaults using an Initialization (Reset)
procedure.
In doing so, you will erase all of your custom programming and processing settings.
Reset procedure should only be used as a last resort as it erases ALL current
processor settings.
The general RESET procedure is described in the Part Three of this user manual.
Upon initial power up, the Falcon 50 is set at the factory default, Password Security Level ADMINISTRATOR
(indicated as ADMIN in the LOCAL / REMOTE connections masks, requiring NO password at the first
access).
Leaving empty the Password field of ADMIN user means keeping the protection
system of Falcon 50 unactive. It is therefore highly suggested to associate a
Password to the ADMIN user in order to grant the access to the Falcon 50
according to given user profiles.
To access the Change Password Sub-menu, press the SYSTEM button.
A special window will appear.
If You have got connection to the Falcon 50 for the first time as ADMIN default profile, as soon as You enter
the SYSTEM page You will be requested to assign a password to the ADMIN user itself.
NOTE: the ADMIN user is always present in the system and can not be deleted/modified. Anyway, You may
create new users holding the same ‘ADMINISTRATOR’ rights and having different name(s).
Page 23
ENG
PASSWORDS & RIGHTS TO ACCESS THE PROCESSOR
Once entered the ADMIN’s password, the next screen will give
the administrator the possibility to enter multiple user name (f.i.
Jack, David, John, Paul, Henry, etc) each one with its own
password and Security level (Broadcaster, Advanced User,
Technician, etc).

LOGIN LIST
The administrator may always get the list of last 12 access to the unit. For each access (login), the LOGINS
page will show user name, user’s level (Technician, Admnistrator, Advanced User, etc), time and date (to get
it, press LOGINS button at the bottom of the SYSTEM screen).
When multiple access from the same user are registrered, only the last access is displayed (i.e.
previous access are overwritten).

AUDIO INPUT SET-UP AND CALIBRATION
AUTOMATIC SWITCHING BETWEEN SOURCES
When selecting the ‘ON FAULT’ option in the SOURCE SELECTION menu, switching between audio
sources (primary and secondary) will be controlled by a built-in audio detector stage.
With four independent and permanent circuits, the Falcon 50 constantly monitors both L & R channels on
each input (Primary and Secondary).
When one of the following conditions occur (according to the FAULT ON menu selection):
-
the Primary Input (both the channels) extinguishes
the Primary Input (both the channels) falls below the threshold (typically set to around –35 dBm),
the difference between Left and Right channel on the primary input exceeds 20 dB
the fail timer is started. Whether the fail time (FTIME) elapses without the signal recovering, then the Falcon
50 switches from the one to the other input ONLY whether a valid signal is present on the Secondary
(stand-by) input.

With ‘On fault’ option selected in the SOURCE SELECTION menu,
the Falcon 50 will switch on the secondary input in the event the

With ‘On fault’ option selected in the SOURCE SELECTION menu, the
Falcon 50 will switch on the secondary input in the event the difference

The ‘silence’ time duration on the Primary input before the Falcon 50 switches (Fault Time) is adjustable from
5 to 60 seconds (by step of 5 seconds) by means of FTIME control in the FAULT TIME menu.
Once the Falcon 50 has switched from Primary to Secondary input, the Primary input may be kept monitored
till the Primary audio input resumes. Also when Primary audio appears, a time ranging from 1 to 10 seconds
may be awaited before inverse switching (from Secondary to Primary) is performed.

With ‘On fault’ option selected in the SOURCE SELECTION menu,
once the Falcon 50 has switched from Primary to Secondary input,
also when Main audio appears, a time equal to Rtime will be awaited
before inverse switching (from Secondary to Primary) is performed.
HINTS & TIPS
Since silence is often a part of normal audio, preset (typical) fail time is around 20 seconds. However time as
long as one minute may be set. In order to ignore momentary levels above the threshold when re-connecting
equipment the restore time for audio is generally set at around 10 seconds, but it may be also easily altered
to longer times.
A full set of alarms (i.e. contact closing and relay switching) may also be triggered for external use.

HOW TO TRIGGER ALARMS ON IN THE EVENT OF INPUT AUDIO FAILURES
The Falcon 50 has wide alarm and signalling capabilities. In particular, audio failure on primary or secondary
sources may trigger several alarms, according to the options selected from the SETUP window (the SETUP
tab is listed in the bar undeneath the central Navigator window).
An alarm condition may occur either on PRIMARY INPUT FAILURE (P.I.F.) or SECONDARY INPUT
FAILURE (S.I.F.) or both.
An alarm condition will turn on the ALARM signalling on the Remote Control screen
and the front panel ‘ALARM’ LED:
Beside turning on that ALARM signalling, each one of the two TTL OUTPUTS may be associated to
individual Input Failures (see TTL OUTPUT 1 in the example screen here below) or to a generic Alarm
condition, as set in the ALARM ON menu (see TTL OUTPUT 2 in the example screen here below).
Alarm will clear itself immediately upon return of input audio.
NOTE: The alarm condition may be also associated to other events, such as extra-temperature, MPX signal
clipping or the MPX modulation level is below 100% for some reason. Ref to ALARM ON menu.

ENG
7.4
AUDIO INPUT SET-UP AND CALIBRATION
SETTING THE PROCESS PRE-EMPHASIS
The frequency characteristic of L & R outputs (either analog or digital) and of MPX outputs can assume
either a flat frequency response, or can follow a selected pre-emphasis curve.
For FM broadcasting worldwide, some form of pre-emphasis boost is employed. Generally it is 50µs or 75µs.
In Europe, Australia, and New Zealand 50µs is employed, while for North and South America 75µs is used.
When ‘flat’ mode is engaged (Pre-emphasis = Off), this yields a signal with a flat frequency characteristic, but
with an output ceiling that exactly follows the inverse of the pre-emphasis curve. Doing so, if the signal is
again pre-emphasized in an external stereo generator or exciter, the transmitted signal will have proper preemphasis and spectral protection.
The actual pre-emphasis time is indicated on the Process Pre-emphasis menu.
The pre-emphasis can be changed with relative ease from the same menu if, for some reason, the unit is to
be operated at a preemphasis which is different to that as supplied

ANALOG INPUT SET-UP
Double click the ANALOG INPUT block
7.5.1 SETTING THE INPUT MODE (MONO, STEREO, SWAP, ETC)
The INPUT MODE menu contains all controls which can be applied to the analog audio source.
The STEREO mode is the common operating mode.
With MONO L option activated, the left signal will feed both left and right output signal paths.
With MONO R option activated, the right signal will feed both left and right output signal paths.
With MONO L+R option activated, the stereo input signal will be mixed to mono and it will feed both output
signal paths.
The SWAP L/R control swaps Left and Right channels (L becomes R and R becomes L).
INVERT L (and INVERT R) inverts the polarity (i.e. reverse the phase) of respective XLR jacks (pin 2 to 3
and 3 to 2).
7.5.2 HIGH PASS FILTER
The Falcon 50 FM input stage also allows to switch on or off a High Pass Filter with 30 Hz frequencies cutoff. The Filter may be proven useful for eliminating wind noise, traffic rumble, and AC mains hum. For most
voice applications the filter can be left activated. For wide bandwidth signals, such as music, the filter should
be used only as necessary.
Page 29
ENG
AUDIO INPUT SET-UP AND CALIBRATION
7.5.3 PHASE ROTATOR
The Phase Rotator circuits, when utilized, can assist in eliminating vocal distortion during periods of heavier
processing needs. These specialized delay circuits create a “flywheel” effect on a certain range of
frequencies. In this case, audio within the main vocal range of 300 Hz to 2 KHz will change in phase as
frequency increases through the set passband.
The reason for using phase rotators is to address a problem created by the human voice. Some human
voices (particularly male voices) exhibit as much as 6dB asymmetry in their waveform, while typical ‘musical’
signals are symmetric.
As asymmetric clipped signals result in a more unpleasant ‘sound’ to the ear than the symmetric clipped
ones, a filter designed to convert asymmetric waveforms into symmetric ones would be very recommended.
Even better, it would be highly recommend to pre-process the live speech (as captured by studio
microphones) through dedicated VOICE PROCESSORS, that are situated between the microphone(s) and
the broadcast mixing console (see figure).
Whenever no voice processors are available and the ‘speech’ material (as sourced by microphones)
is directly passed to the processor inputs, You may activate the phase rotator input stage, that removes
the asymmetrical waveforms from the incoming audio signal, thus giving significant improvements on speech
processing and removing any distortion.
Although the ‘Phase Rotator’ stage is a special all-pass filter designed to properly modify live speech
material, it may be set as ‘enabled’ even when ‘music’ signals are processed, as it doesn’t affect in a
perceivable mode the most part of that kind of signals. However, we suggest to keep it off in every ‘all music’
station, when no live speech interventions are performed.
Three rotation levels are provided, each one having different impact on the ‘live’ speech material. Without
being involved in mathematical explanations, we suggest to try all the levels and choose the one which best
fits the actual program material being fed to the processor. The Phase Rotator is set OFF as default.
In addition to the Phase Rotator stage, the Falcon 50 features a Speech Detector stage able to
recognize speech components inside the incoming audio and to automatically adjust processing
parameters for best result. Refer to relevant Chapter.
All factory Presets have Speech Detector stage activated (even if at different levels).

The first step in the Falcon 50 Input calibration consists in stating the Analog-to-Digital Clip level. The Clip
Level (or “fullscale digital”) is a hard digital ceiling above which no signal can go. That is, the highest level
attainable in a digital system (a word of all binary 1’s). It is also indicated as 0 dBFS.
Distortion occurs once the audio level is louder than what the A/D chip can read (“above” 0 dBFS – see
curve on the right in the figure), while too low Signal-to-Noise ratios are achieved whenever the clip level is
set too high in respect of the input signal.
The clipping point should be adjusted in such a way that the processor clipping level fits the clipping
point of the audio system / chain (mixing console, audio changeovers, matrix/routers, etc) feeding
the processor input.
Use care and attention in setting this adjustment.
Clipping Point is set at +18dBu factory default for FM version, while for TV version it is set at
+12dBu factory default.
To calibrate the Clipping Point using Program audio material, do the following:
1) Feed the processor input with the highest undistorted audio level. Tipically, You get this worst
condition by raising-up all sliders on the mixing console or turning up the output volume of signal routers,
changeovers, etc chained with the console.
2) Adjust the Clipping Point parameter in the Falcon 50 menu so that on program peaks the input meters
indicate approximately –1 or -2 dB. The top level on the meters correspond to the A/D converter clipping
point. Proper input levels for the Falcon 50 should have the second and third red meter indicators light
on.
3) Recover standard source levels and pay attention to the peak working zone.
If the peak ranges between –15 dB and –10 dB, the input stage is correctly tuned. Otherwise, re-adjust
the Clipping level so that peaks in standard operation match the above condition(in particular, they never
overpass – 10 dB).
Minimum Headroom allowed by the system is 6 dB. That is, the condition (ClippingPoint –
Adref)>=6dB is automatically enforced.
Page 31
ENG
AUDIO INPUT SET-UP AND CALIBRATION
As optimal working level, it is advised to set the Clipping Point so that the input signal peak ranges between
– 10 and – 15 dB on the Input meters.
It is strongly suggested to monitor the Input meters for reasonably long time, in order to fit in the best way
the input signal trend.
ADJUSTING THE A/D REFERENCE LEVEL
1) Feed the processor input with audio material at a standard level (normally 0 Vu on the mixing console
meters).
2) Select one of the factory default processing curves. It is recommended to setup the processor input
using the same curve as in the normal operation.
3) Adjust the A/D reference level so that on program peaks the AGC meters indicate approximately – 10
dB gain reduction.
The A/D REFERENCE parameter acts as a SENSITIVITY control. Thus, feeding the Falcon 50 FM with a
0 dBu signal and having the A/D Reference point set at – 10 dBu, the cascaded AGC stage will compensate
for 10 dB with the AGC Drive control set to 0.
Minimum headroom is 6 dB. Clipping the input signal will generate an ALARM if the ‘CLIPPING’
option is selected in the ALARM ON menu included in the SETUP screen.
ADDITIONAL NOTES
The A/D Reference Level is set at 0dBu factory default for FM version, while for TV version it is set at -5dBu
factory default.
On professional analog consoles, 0 VU on the console meter often equates to the professional reference
level of +4 dBu.
So, for example, if the processor’s inputs are calibrated to +4 dBu = -16 dBFS, then +20 dBu = 0 dBFS.
Thus, an input level greater than +20 dBu would cause the converter to distort.
By setting the clipping point to, f.i., + 18 dBu, if the XLR input analog PEAK level is as high as +18 dBu,
which is 6.16Volt RMS, this will give a 0dBFS reading. Top red LED indicates 0dBFS. From 0 dBFS to 60dBFS the readout resolution is 1dB. From –5 dBFS to 60dBFS the readout is indicated by green LEDs.
It is recommended to adjust the input signal to a maximum, peak value of –12dBFS. This means that the
meter normally reads out ‘green’ values. This way a 12 dB headroom is preserved.
EXAMPLES
Having set the Clipping Point at + 20 dBu and reading out – 20 dB on the Analog input meter, the signal
being fed is 0 dBu (no matter of A/D Reference Point).
By re-adjusting the Clipping Point to + 10 dBu and keeping the input signal at 0 dBu, meters will read – 10
dB.
Having set the Clipping Point at + 24 dBu, for good operation the input signal can range up to + 10 dBu, thus
keeping 14 dB of headroom.

DIGITAL INPUT SET-UP
Double click the highlighted block:
7.6.1 SETTING THE INPUT MODE (MONO, STEREO, SWAP, ETC)
The INPUT MODE menu contains all controll which can be applied to the analog audio source.
The STEREO mode is the common operating mode.
With MONO L option activated, the left signal will feed both left and right output signal paths.
With MONO R option activated, the right signal will feed both left and right output signal paths.
With MONO L+R option activated, the stereo input signal will be mixed to mono and it will feed both output
signal paths.
The SWAP L/R control swaps Left and Right channels (L becomes R and R becomes L).
INVERT L (and INVERT R) inverts the polarity (i.e. reverse the phase) of respective XLR jacks (pin 2 to 3
and 3 to 2).
7.6.2 HIGH PASS FILTER
The Falcon 50 FM input stage also allows to switch on or off a High Pass Filter with 30 Hz frequencies cutoff. The Filter may be proven useful for eliminating wind noise, traffic rumble, and AC mains hum. For most
voice applications the filter can be left activated. For widebandwidth signals, such as music, the filter should
be used only as necessary.
Page 33
ENG
AUDIO INPUT SET-UP AND CALIBRATION
7.6.3 PHASE ROTATOR
The Phase Rotator circuits, when utilized, can assist in eliminating vocal distortion during periods of heavier
processing needs. These specialized delay circuits create a “flywheel” effect on a certain range of
frequencies. In this case, audio within the main vocal range of 300Hz to 2kHz will change in phase as
frequency increases through the set passband.
The reason for using phase rotators is to address a problem created by the human voice. Some human
voices (particularly male voices) exhibit as much as 6dB asymmetry in their waveform, while typical ‘musical’
signals are symmetric.
As asymmetric clipped signals result in a more unpleasant ‘sound’ to the ear than the symmetric clipped
ones, a filter designed to convert asymmetric waveforms into symmetric ones would be very recommended.
Even better, it would be highly recommend to pre-process the live speech (as captured by studio
microphones) through dedicated VOICE PROCESSORS, that are situated between the microphone(s) and
the broadcast mixing console (see figure).
Whenever no voice processors are available and the ‘speech’ material (as sourced by microphones)
is directly passed to the processor inputs, You may activate the phase rotator input stage, that removes
the asymmetrical waveforms from the incoming audio signal, thus giving significant improvements on speech
processing and removing any distortion.
Although the ‘Phase Rotator’ stage is a special all-pass filter designed to properly modify live speech
material, it may be set as ‘enabled’ even when ‘music’ signals are processed, as it doesn’t affect in a
perceivable mode the most part of that kind of signals. However, we suggest to keep it off in every ‘all music’
station, when no live speech interventions are performed.
Three rotation levels are provided, each one having different impact on the ‘live’ speech material. Without
being involved in mathematical explanations, we suggest to try all the levels and choose the one which best
fits the actual program material being feeded to the processor.

7.6.4 DIGITAL INTERFACE SETUP – QUICK START
1)
Choose the sampling resolution (16, 20 or 24 bits) which best fit the actual digital audio source.
2)
Play program audio material from your studio, peaking at the level to which you normally peak program
material (typically 0VU on analogue mixing consoles).
3)
Select one of the factory default processing curves. It is recommended to setup the processor input
using the same curve as in the normal operation.
4)
Adjust the Digital Reference level so that on program peaks the AGC meters indicate approximately –
10 dB gain reduction.
ADDITIONAL NOTES
If you use a tone to line the meters up with your console, then with your console’s meters at 0VU, set the
Digital Reference level control for either -18dBFS or -12dBFS on the Falcon 50’s meters, depending on the
amount of desired headroom.
0 dBFS is the absolute highest voltage level that any particular A/D converter can convert. It produces the
equivalent of a digital code consisting of all 1s. No digital level can exceed 0 dBFS. A 0 dBFS voltage level
and all levels greater than this produce the same output code of all 1s.
On the contrary of analog signals, digital signals can range in the red meter zone without involving any
distortion or signal degradation.
The Digital Reference parameter has the same meaning as the Analog Reference parameter in the analog
input.
This is just a starting point, and you may want to alter this relationship.
The Digital Reference level affects both L + R channels simultaneously.

ANALOG OUTPUT CALIBRATION
Double click the highlighted block:
8.1.1 OUTPUT SOURCE SELECTION
In the PROC position, this switch routes the input audio program signal through the whole processing
circuitry. It is the NORMAL OPERATING position.
When INP (Input) is selected as output source, program audio completely bypasses the processing section
and the analog audio XLR jacks provide the signal at the input, according to the equipment block diagram.
The INP position defeats program audio pre-emphasis as well.
With GEN source selected, the analog output is fed by selectable tones (sinewave) as stated in the
INTERNAL GENERATOR menu (see).
With MON source selected, the analog output is fed by the signal picked-up after the input stage, the
Equaliser stage, the Compressor stage or the final output stage, according to the selection done in the
Monitor box. For more details, refer to equipment block diagram.
8.1.2 DE-EMPHASIS & GROUP DELAY
Preemphasis may be selectively removed from the anaolog output by turning the De-emphasis filter to OFF.
Output Group Delay is adjustable within the range [0-3 uSec]
8.1.3 D/A CONVERSION SETUP
Clipping point (level) of output D/A converter should match the clipping point of connected (load) equipment.
Adjust the D/A reference control so that You match the input sensibility of target equipment.

8.1.4 MATCHING THE LOAD IMPEDANCE
The OUT IMP menu helps in matching at the best the actual input impedance of the load (transmitter, stereo
coder, exciter, etc) connected to the processor.
HavinG the Falcon 50 analog outputs a typical source impedance of 50 Ohms, the output level varies by up
to 0.8 dB when connecting 600 Ohms loads rather than 10 K loads.
The Clipping Point is set at +18dBu factory default for FM version, while for TV version it is set at

MPX OUTPUTS CONFIGURATION AND LEVELS (available only on FM version)
Double clicking the MPX SETUP block You will get access to the all controls common to both outputs:
8.3.1 OUTPUT SOURCE SELECTION
When INP (Input) is selected as output source, program audio completely bypasses the processing section
and the analog audio XLR jacks provide the signal at the input, according to the equipment block diagram.
The INP position defeats program audio pre-emphasis as well.
In the PROC position, this switch routes the input audio program signal through the whole processing
circuitry. It is the NORMAL OPERATING position.
With GEN source selected, the analog output is fed by selectable tones (sinewave) as stated in the
INTERNAL GENERATOR menu (see).
8.3.2 PILOT LEVEL AND PHASE
Pilot Level: The default is set to – 20 dB compared to the overall Stereo Composite MPX signal. Use the +/buttons to change this level within the range of –14 dB to – 26 dB, in 0.1 dB steps. The pilot signal may also
be disabled by using appropriate controls on the MPX OUTPUT blocks.
Pilot Phase: may be adjusted from – 12.0 to + 12.0 degrees (Deg) in 1 degree steps. The Phase selection
allows you to adjust the phase relationship between the 19kHz pilot and the 38kHz modulator. This can be
used to correct for inconsistencies among different transmitters.

AUDIO OUTPUTS SET-UP & CALIBRATION
8.3.3 SELECTABLE MPX ATTENUATION
The amount of Composite MPX signal sourced by the Falcon 50 internal processing may be reduced by 1 to
100% in selected steps in order to accomodate externally injected signals such as RDS and SCA while
maintaining constant the overall MPX level at the processor output.
In particular, the Falcon 50 control allows for MPX reduction in two steps completely user-definable and
associated to the activation of selectable Inputs on the General Purpose (GP) Input interface.
EXAMPLE
Activating External Input 5 will cause the sourced Falcon 50 Composite signal to
be reduced by 6 %.
Activating External Input 3 will cause the sourced Falcon 50 Composite signal to
be reduced by 9 %.
Activating both External Input 5 and External Input 3 at the same time will cause
the sourced Falcon 50 Composite signal to be reduced by 15 % (6+9).
NOTE: By choosing an attenuation factor of 100 %, the Falcon 50 processed composite signal will be totally
removed from the output.
8.3.4 MPX POWER LIMITER CONTROL (ITU 412)
The ITU BS-412 regulation aims to reduce the density of the modulated signal while maintaining the same
peak deviation level in order to ensure minimal or limited co-channel interference.
The BS-412 definition says:
“It is assumed that the maximum peak deviation of ± 75 kHz is not exceeded. Moreover, it is assumed that
the power of the complete multiplex signal (including pilot-tone and additional signals) integrated over any
interval of 60 seconds is not higher than the power of a multiplex signal containing a single sinusoidal tone
which causes a peak deviation of ± 19 kHz.”
In essence, the regulation installs a 12dB peak-to-average ratio on the processing.
It is possible to adjust the Falcon 50 Composite MPX outputs so that they will adhere to the BS-412
regulation.
WARNING!
The POWER LIMITER default setting is Off. Many European countries are enforcing
ITU-R 412 recommendation. However, if your country’s laws do not require the use of
the MPX Power Limiter, make sure that the Power Control is set to off, or severe loss
of loudness will result!
E.g, with the ITU BS-412 Power Limiter set to on at 0.0dB, there are approximately 5
to 8 dB loudness loss over the limiter being switched off!
To enable the output power limiting, turn the Mpx Power Control to ON. Power threshold can be then
increased from 0 to + 12 dB in steps by 0.1 dB.
The output power calculation does take into account the injection values of the Pilot, external RDS
signal and possible SCA signals.
Page 40
ENG
AUDIO OUTPUTS SET-UP & CALIBRATION
The Falcon 50 FM presents several ITU-complaint presets, which have a density level fitting
at the best the subsequent Power Limiter stage.
To get the best result with the Power Limiter stage, use Presets marked as ‘ITU’.

MPX OUTPUT LEVELS AND MODES (only on FM version)
8.4.1 MPX 1 & MPX 2 OUTPUT LEVELS
Individual controls are provided for the two composite outputs. This will allow equipment requiring different
output levels to be adjusted appropriately. Refer also to the Par, SELECTABLE MPX ATTENUATION for
Attenuation controls.
8.4.2 CLIPPER MPX
Adjustable between 95 % and 105%, the Clipper stage operates within the pre-pilot signal region and is
performed on the L+R and L-R signals before the pilot signal is inserted. This design guarantees that the
clipper action is clipping just the dynamic composite signal and never the pilot signal.
The Clipper stage may be also turned to OFF from the same menu. When off, the Composite Clipper circuit
is totally bypassed and removed from the system.
Whenever an ‘aggressive’ modulation (i.e. Density increment to the detriment of ‘Definition’) is desired, the
Clipping Point should be set < 100 %, while whenever a ‘protective’ modulation is requested, the Clipping
Point will be set > 100 %.
The Falcon 50 FM clipping stage is based on the principle of having a fixed clipping level and of expanding
(so applying a positive Gain) to the Modulated signal to be clipped or of reducing (so applying a negative
Gain) to the Modulated signal.
The applied Gain will be calculated according to the following formula:
Gain = 100 % - Clipping Point paramater value.
F.I., having set the Clipping point parameter to 97%, the Gain will be 100 % - 97% = 3%, thus yielding to a
Density increment by 3 %. The Modulation level is kept at the 100 %.
On the contrary, setting the Clipping Point to f.i. 104%, the applied gain will be 100 % - 104% = - 4 %.
Without Clipper stage activated, the Modulation peaks will overpass by 2 or 3 KHz the 100 % limit.
It is highly suggested to set the Clipping Point to the default value of 100 %, thus avoiding any modulation
distortion and preserving at the most the processed sound quality.
The Clipping Point range has been designed so that even setting it to 95 % the Pilot Protection factor
exceeds 60 dB.

QUICK START – CREATING A NEW PRESET
2 QUICK START – CREATING A NEW PRESET
This chapter presents a very easy and fast way to create a new preset beginning from a factory one.
2.1
USING THE WIZARD TO SET DENSITY, COMPRESSION AND SOUND
‘FOOTPRINT’
Pick out the factory preset which best fits the desired ‘sound footprint’
open the 6-BAND AUDIO PROCESS BLOCK and then click
the WIZARD tab
Enter the WIZARD screen. Alter the listed Macroparameters
very slowly while listening how the original output sound
modifies. When satisfied with the new sound, click OK. Click
UNDO to discard last modifications or ESC to quit the screen
without saving.
NOTE: value ranges shown in the WIZARD window are
tailored on the processing Preset being modified and do not
represent any ‘absolute’ limit of the Falcon 50 processing.
Enter the EQUALIZATION block (EQ), and modify the filter
parameters first and then consider each filter effect by turning
it on and off from the relevant function. It is possible to set the
amplitude of each filter window. Click UNDO to discard last
modifications or ESC to quit the screen without saving.
Enter the STEREO ENHANCER block (SE) and alter its
parameters at will. At the moment, keep unaltered both
Brilliance and Multiband Controls. Click UNDO to discard last
modifications or ESC to quit the screen without saving.
Double click the BAND 1 block: the SUPER BASS menu will
be shown. Alter the Bass Type and BassLevel at will and then
consider the filter intervention by turning it on and off. Listen to
its actual effect and keep the preferred setting. Enter controls
of each Band and try to alter their PreDrive controls. You may
increase them by up to 1 dB, while You may decrement them
at will.
Light modifications are also permitted in the Band Mixer stage
(Band Mixer + Final Limiter block), with increments by up to
0.5dB, while decrements have no limits. Once reached the
desired sound stamp, keep it listening carefully to for a
sufficiently long time. Also adjust the Power Attenuation
(PowerAtt) parameter so that the PA meter on the screen acts
as little as possible while applying a slight attenuation. If there
still is something wrong with the sound (that is something
different from a specific sound detail) and You are unable to
find a relationship with any band in particular, slightly reduce
the Final Limiter Drive, or switch to a more smooth Clipping
mode (f.i. from Hardest to Hard)
Page 4
QUICK START – CREATING A NEW PRESETENG
If You are able to detect a specific sound component (f.i. a
specific instrument or frequency) giving bad results on the
final output, try to identify the band or the bands involved and
try to reduce their LIMITER Thresholds. Use the SOLO
MODE control provided in each band in order to easier identify
the specific contribution of that band to the final output.
If live speech is fed at the input, test how the various Speech
Detector modes (included in the SE block) alter the voice
‘colour’. In the event an external Voice/Mic Processor is used
or music only is processed, select MODE 1 or turn it OFF.
NOTE: the MODE 1 is the only mode completely ‘flat’ (that is,
it doesn’t alter the original freq balance in the audio to be
processed), while other MODE profiles change speech
equalisation.
2.2
SETTING THE AGC & MULTI-BAND SPEEDS
Factory presets have been designed in order to react in a quite slow manner to all level variations of input
signal. However, the final user may alter that behaviour at any moment. It is advisable to to test the chosen
Preset in ‘extreme’ conditions, i.e. when the audio program to be processed contains very low music levels
or very high levels. If faster reaction to those audio contents is desired, modify the AGC WINDOWS and
AGC RELEASE parameters.
It is also advisable to increase the Thresholds of AGC Gate (GateThr) and MULTIBAND Gate parameters
(the latter one being inside the SE block) in order to help the Agc stage in freezing the lowest levels not to be
enhanced.
HINTS AND TIPS: if You have reached a pleasant trade-off between sound components with a very good
loudness having as a reference Your preferred Hi-Fi domestic tuner, amplifier and speakers set and the
result is significantly different when a car-radio or a small transitor is used instead, perhaps You exagerated
in ‘pumping’ very low freqs (below 100 Hz) or very high ones (10 Khz or over). In one word, it is
recommended to create Your own processing Presets having as a reference/target a specific tuner type
(home, car, portable, etc), likely the most used by the majority of Your listeners.
As a reference, the so-called ROCK Presets done in the factory are as much ‘universal’ as possible (that is,
they do not suffer when reproduced on small loudspakers or poor performance systems), while the HOT
ones have significant enhancement on low and high freqs and could not fit every sound reproduction system.

QUICK START – CREATING A NEW PRESET
HOW TO CREATE AN ITU-B412 COMPLIANT PRESET FROM A NOT
COMPATIBLE ONE.
Factory Presets ranging from 40 to 49 have been designed to meet ITU-B412 specifications.
Thus, for an ITU-compliant broadcasting, You just need to load one of the ITU Presets (which are
directly derived from the most common not-ITU ones) and turn the MPX POWER CONTROL in the
MPX SETUP block on.
Alternatively, You may want to create an ITU-B412 compliant Preset having as a reference a Not-ITU one.
To do this, select the Preset* You would like to begin from,
open the FINAL LIMITER block and change the Drive control to a
value less than – 1.5 dB (- 1.8 dB suggested).
Also select the Clipping mode = SMOOTH and regulate the
PowerAttenuation parameter to – 9.5 dB.
Enable the MPX POWER CONTROL in the MPX SETUP block.
We suggest to listen to the created Preset for a long time. I.e., if You will be still able to appreciate slow
and light level variations on the created Preset, reduce the Limiter Drive parameter (f.i. set it to - 2.2 dB or –
2.5 dB).
* the Preset to begin from should be carefully selected, as not all factory Presets are suitable for an ITU
operation

HOW TO CHANGE THE PRESET ON AIRENG
3 HOW TO CHANGE THE PRESET ON AIR
The processor has 100 curves: the factory presets (PR) are stored in positions 00 through 49, while positions
50 to 99 may be set by the operator.
Before creating a new custom curve, we recommend that you carefully evaluate the factory presets,
all of which are suitable for immediate on-air use given their average content of the various signal
components.
To change the Preset currently on-air, double click the PRESETS block.
The CHANGE PRESET mask shows the current Preset (On Air), while the alternative one is shown in the
Preset field.
Using the mouse wheel or the +/- keys scroll the Preset list till You reach the desired new curve.
Pressing LOAD, the new Preset will be put on air immediately, while the CHANGE PRESET screen will not
close allowing You to select a new Preset, if desired.
Pressing OK, the new Preset will be put on air immediately, and the CHANGE PRESET screen will close.
The software screen header will now show the selected Preset:

SAVING A NEW PRESET
4 SAVING A NEW PRESET
As preferred way to create a new Preset, it is advisable to pick up one of the existing one (either Factory
done or user set) and alter it in order to get the sound You want.
To pick up one of existing presets, refer to the previous chapter. Once the Preset is on air, double click the 6BAND AUDIO PROCESS block to edit it.
At the top left corner the EDIT PRESET menu will always prompt which Preset You are going to modify.
As soon as You enter one of the processing blocks (AGC, SE, EQ, etc) and You alter one of its parameter
(f.i. You increase the AGC Release speed), the screen header will revert to the the EDIT BUFFER ON AIR
mode, thus informing the user that the original Preset has been modified and he/she is currently listening to
the modified one.
The output sound is changed in real time according to the values displayed moment by moment in each
block.
Once finished the modification task, click the SAVE button.
The SAVE PRESET window prompts You to choose the memory location where the new Preset will be
saved (locations from 50 to 99) and to enter a menmonic name for that Preset.
Clicking OK the just created Preset is imediately put On Air.
The same SAVE PRESET message is also displayed every time You quit the 6-BAND AUDIO PROCESS
BLOCK after having altered any parameter.

CHANGING PRESETS ON A DAY-PART AUTOMATION BASISENG
5 CHANGING PRESETS ON A DAY-PART AUTOMATION BASIS
Once a new Prset is defined, it can be saved and loaded into a daypart scheduler to change to a different
processing preset at a fixed time of day. The clock in the Falcon 50 FM can be set manually or via the Pc
Control Software.
To schedule Prset change during the day, proceed as follows:
1) make sure the Falcon 50 internal clock time matches the current one. If not, use the Pc control
software to synchronize
2) make sure all Presets You would like to schedule are already saved into the Falcon 50 memories.
3) The Schedule will allows You to automatically put on air a specific Preset (curve) at a specific time
and for a specific duration (time band). This Preset will replace, at that starting time, the default one
being currently broadcast. Make sure of the default Preset, which is on air whenever no other
Presets are scheduled. The default Preset is selected using the procedure shown on Chapter 3.
4) open the AUTOMATION screen by selecting the associated TAB as in the picture:
5) press ENTER on the shown PRESET AUTOMATION WINDOW to start editing a new PRESET
event: the EDIT EVENT window will be displayed.
PRESET: use the Jog Wheel on the Front Panel or the +/- keys on the keyboard to scroll the Preset list until
You reach the desired one
From/To: it selects the time the new Preset starts replacing the default one on-air and the end time the new
Preset is removed from air. use the Jog Wheel on the Front Panel or the +/- keys on the keyboard to scroll
the Preset list until You reach the desired hour and minutes. Left/Right arrows will let You move from one
block to the other.
Enable: Use the Left/Right arrows to highlight each single Week’s day (Mo=Monday, Tu = Tueasday, etc).
Press ENTER (or press the Jog Wheel) to select the highlighted day. Highlighted (selected) days are
identified by a double square symbol, as in the picture:

IMPORTING/EXPORTING AND MANAGING CONFIG FILESENG
6 IMPORTING/EXPORTING AND MANAGING CONFIG FILES
6.1
EXPORTING SINGLE PRESETS, GENERAL CONFIG OR BOTH
The Falcon 50 control software contains special tools to selectively export in a file (to be saved on Yr local
Pc, to be emailed, to be held on a CD Rom for future use, etc) a single custom preset (that is, a processing
preset created by the user), all user presets, the general equipment configuration/status (that is: input
setting, output settings, pilot level, passwords, etc) or either the latter ones (all Presets + equipment Status).
It is strongly recommended to export in a file the actual equipment STATUS as soon as
You have reached a final / good configuration on the processor. This file must be retained for
future use (f.i., to reload a valid configuration after a reset, to clone the same configuration on
multiple units, etc).
To EXPORT single presets, all presets, Status or ‘all’ in a file, click the CONFIG button on the software
screen (placed just below the large navigation buttons).
EXPORT PRESET
Exports in a file the Preset selected in the small black window (from 50 to 99)
EXPORT PRESETS
Exports in a file ALL processing presets created by the user (from 50 to 99)
EXPORT STATUS
Exports in a file the general configuration (in and out interfaces, levels, passwords,
etc) of the processor. Presets are NOT included.
EXPORT ALL
Exports in a file the general configuration plus ALL user Presets (RECOMMENDED)
Click the desired option and save file following standard operating system procedure.

6.2
IMPORTING/EXPORTING AND MANAGING CONFIG FILES
IMPORTING PRESETS, GENERAL CONFIG. OR BOTH
The Falcon 50 control software contains special tools to selectively import from a file a single custom preset,
all user presets, a general equipment configuration/status (that is: input setting, output settings, pilot level,
passwords, etc) or either the latter ones (all Presets + equipment Status).
Clik the CONFIG large button on the software screen, and then click the IMPORT buttons according to their
scope:
IMPORT PRESET
Imports a single processing Preset from a file and places it in the memory position
according to the selection done in the small black window (memory positions from
50 to 99)
IMPORT PRESETS
Imports the whole set of 50 processing USER Presets from a file. All current User
presets will be overwritten.
IMPORT STATUS
Imports from a file the general configuration (in and out interfaces, levels,
passwords, etc) of the processor. Presets are NOT included. The current
configuration will be lost.
IMPORT ALL
Imports from a file the general configuration plus ALL user Presets. The whole
current configuration and presets will be overwritten.
Clicking one of these buttons, a window will appear. Look for the folder containing the user-defined files. You
can find the default folder at the following path: C:\Programs\Axel Technology\Axel Falcon 50 vx.x.x\User
Files.
Here you will find a range of factory default Presets that you can use and modify. We highly suggest to try
and test these files
Once You are into the folder, select the desired file and open it.

AGC OPERATIONENG
7 AGC OPERATION
Double Click the 6-BAND AUDIO PROCESS block on the main screen.
Double click the AGC block. The AGC screen will open:
One of the most important processor function is the Automatic Gain Control (AGC) system, which
compensates for variations in the input level while keeping the signal at its normalized internal level of 0 dBr.
Several parameters regulate the AGC function and may be modified, as shown in the AGC screen.
The bargraph indicators displays the amount of correction in effect for long-term variations in
the program input signal.
As the Agc stage is a true two band stage, thus each of two L & R channels is splitted into two
bands.
7.1
TURNING THE AGC ON/OFF
When needed, the AGC stage can be totally defeated by turning the Agc control to Disabled.
7.2
SETTING THE AGC SPEED
The AGC speed value is expressed in dB/sec – i.e. the number of dB amplified or attenuated in one second.
The Falcon 50 allows You to set two different working speeds for the AGC main operation: the Attack speed
and the Release speed, where the first one is normally significantly higher than the second one. High AGC
Speed values obviously make it possible to quickly recover strong level differences, but they can also lead to
unpleasant ‘pumping’ effects. We suggest using medium speed levels of around 1 ÷ 2 dB/sec, and especially
that you concentrate on the audio sources connected to the processor, to obtain the most even sound
possible.
Page 13
ENG
AGC OPERATION
When the AGC level is getting close to its internal reference level when releasing, the AGC will enter a so
called WORK ZONE, where the AGC speed is reduced to the WZ Rel value stated in the AGC WINDOWS
menu.
The dimension of the WORK Zone is stated by the WZ Thr (Work Zone Threshold) parameter.
The WORK ZONE interval (which ranges from the negative level expressed by the WZ Thr parameter to the
0 dBr internal reference) has been introduced because high compression and high amplification speed on
the whole band could engender unpleasant pumping effects.
The Attack speed sets the speed the AGC will use to react to sudden and unaxpected transient of input
signal (exceeding 0 dBr), which could bring to improper, large increment of output level.
Basically, the Attack time should be set according to the music contents and type (Classical, Rock, etc) being
broadcast.
EXAMPLE 1 – SETTING AGC SPEEDS FOR GENERAL PURPOSE OPERATION
Having set AGC Release speed = + 2 dB/sec and WZ Thr = + 4 dB, an input signal of – 14 dBm will be
amplified to – 4 dB in exactly 5 seconds. Once entered the Work Zone, the approach to the 0 dBr threshold
will be slower, and equal to the WZ Rel speed. Having the latter set to 0.5 dB/sec, the whole travel will take 5
+ 8 = 13 seconds.
NOTE: this is a very theorically AGC operation. In fact, the MultiBand stage (featuring its own AGC control)
will also contribute to normalize the level.
EXAMPLE 2 – SETTING AGC SPEEDS FOR EXTREME OPERATION
This setting is indicated when large level gap should be compensate in the shortest time. Having set AGC
Release speed = + 5 dB/sec and WZ Thr = 1 dB, an input signal of – 16 dBm will be amplified to – 1 dB in
exactly 3 seconds. Once entered the Work Zone, the approach to the 0 dBr threshold will be slower, and
equal to the WZ Rel speed. Having the latter set to 1 dB/sec, the whole travel will take 3 + 1 = 4 seconds.
7.3
SETTING DRIVE, IDLE AND GATE PARAMETERS
The Agc stage may be considered as a Compressor stage with a positive Drive. The Drive value represents
the AGC Max Gain, i.e. the maximum amplification value attainable by the AGC system. Thus, a Drive not
null means AGC can increase low levels fed at its input.
EXAMPLES
Condition
Drive = 0
- having an input signal at + 8 dBr*, the AGC meter will read – 8 dB and the AGC stage will
output 0 dBr (the AGC stage is always capable to attenuate large signals)
- having an input signal at –2 dBr*, the AGC meter will read 0 and the AGC stage will output –
2 dBr (there is no capability to add Gain, as the Drive factor is null)
Drive = 3
- having an input signal at + 8 dBr*, the AGC meter will read – 11 dB and the AGC output will
be 0 dBr (the AGC stage is always capable to attenuate large signals)
- having an input signal at –2 dBr*, the AGC meter will read - 1 and the AGC stage will output 0
2 dBr (the Agc stage is able to compensate for low signal, as Drive factor is not null)
* if the input signal is rated at the same level of A/D Reference, this is also the level of the signal being fed to
the processor.
Drive parameter may be considered as the maximum amplification value attainable by the AGC system.
For instance, setting Drive = +12 dB means that maximum amplification is +12dB: thus a –12dB signal can
be compensated to 0, while a –15dB signal will reach a maximum of –3dB.
Page 14
AGC OPERATIONENG
7.4
SETTING IDLE COMP, IDLE SPEED AND GATE THRESHOLD PARAMETERS
The two parameters IDLE Comp and IDLESpeed set the behaviour of AGC stage when the input signal is
‘silent’ or it falls under the Gate Threshold (see GateThr parameter).
The Idle Comp sets the Compression rate the AGC will reach when no signal is provided at the input.
The Idle Speed sets the AGC speed to reach that point.
Whit IdleSpeed = locked, the AGC freezes at its current status as soon as the input signal is removed or
drops under threshold.
It is advisable to set IdleComp = Drive
The GateThr parameter indicates the threshold level under which the AGC system is frozen, and does not
amplify the signal. While operating without the signal, the look-up table on the software screen visualizes the
AGC GATED status.
NB: the AGC stage wait a fixed time of 0.5 sec before intervening when the signal varies.
7.5
SETTING CHANNEL LINKAGE AND BAND COUPLING
The AGC circuit may work with left/right channel completely correlated, uncorrelated or partially correlated
(with percentage user-definable).
With L/R Linkage = 100 % the overall circuit gain is controlled by the greater of the left or right channel
signals
With L/R Linkage = 0 % the AGC control is completely splitted over the two channels (i.e an indipendent
AGC control is applied to each channel).
As general rule, a percentage = 70 % may help in compensate for slight difference in levels (up to around 3
dB) between input L and R channels.
In the same way, the AGC circuit may work with two bands completely correlated, uncorrelated or partially
correlated (with percentage user-definable).
With Band Coupling = 100 % the overall circuit gain is controlled by the greater level on the top or bottom
bands
With Band Coupling = 0 % the AGC control is completely splitted over the two bands (i.e an indipendent
AGC control is applied to each band, thus resulting on a kind of audio equalization).
As general rule, a percentage = 70 % (in association with a Crossing frequency and Cross slope between
bands well tuned on the actual audio material to be processed) may help in controlling ‘drum beats’ or low
frequency ‘punch’ music components which may alter AGC operation on higher frequencies.

10.2 GENERAL SYSTEM RESET
This document describes the procedure to perform a general hardware Reset.
10.2.1 BEFORE BEGINNING
WARNING!
Save your presets! This reset procedure will cause all of your presets to be definitely
erased. If you have a computer with Pc Control Software installed, transfer them to
the computer as described in the manual (EXPORT ALL procedure).
If you don't, write down the settings for each parameter.
10.2.2 RESET PROCEDURE
-
REMOVE POWER from the Falcon 50 by disconnecting the AC power cord.
-
REMOVE the TOP COVER from the unit by removing the screws around the periphery of the cover.
-
PLACE the UNIT in front of you with the FRONT PANEL facing you. All instructions are described
and/or shown with the unit in this position
-
Locate the jumper marked JP1 on the left of the main board (see diagram here below).
-
Reconnect the AC power cord to the rear of the unit.
Page 20
APPENDIX AENG
-
Switch the equipment On
-
set the jumper JP1 to its LEFT (external) position: as soon as the Jumper will be set, the three front
LEDs OPERATE, PC-LINK and ALARM will light firmly
-
Remove and set again the Jumper in its Left position quickly: the OPERATE LED will turn Off
-
Now, remove and quickly set again the Jumper in its Left position: the PC-LINK LED will also turn Off
-
As third step, remove and set again the Jumper in its Left position very fast: all LEDs will start blinking
-
At this moment, the Reset has not been already performed and You still have a ‘back door’ to get the
system back to work without loosing its current configuration. In the event You would like not to reset
the unit any more, switch off and then on again. If You want to still reset the unit, wait till the end of
blinking sequence: as soon as the OPERATE LED will resume to blink, the generale reset is
successfully performed.
