2 INTRODUCTION
Thanks to its long experience in the DSP audio field, Axel Technology is proud to present Falcon 15, a 3 band
audio digital processor for FM radio broadcasting.
Falcon 15 offers the proven competitive advantages of all-digital processing: operation versatility, instantaneous
preset recall, Pc control, upgrade capability, consistent high quality, easy installation / configuration…
Typical applications for the Falcon 15 are small and medium radio stations, radio relay stations and advertising
splitting systems.
Falcon 15 comes with an user-friendly and reliable Pc control software which allows easy operations and a
constant monitoring of all processing and modulation parameters.
Falcon 15 has been refined over a period of years by an experienced team of technicians, psycho-acoustic
experts and designers specializing in the development of professional audio equipment based on DSP
technology
The Falcon 15 processing stage provides for analog stereo audio inputs (a digital input is available as an option).
You can choose between two Falcon 15 models, featuring two different Output types
: analog stereo or composite
MPX (i.e. suitable for a direct transmitter connection or a STL radio link).
Falcon 15 processing is based on 3 compressors related to Bass, Mid and High audio bands. The wide range of
preset curves and the sophisticated AGC stage allows all users (even unskilled) to achieve astonishing results for
density, richness and colour of the sound… An unique ‘signature’ for Yr radio sound !
Main Features
The digital MPX stereo coder (built-in) makes adjustements easy. The Falcon 15’s performance is enhanced by
the addition of the Stereo Coder which ensures the best ratio between signal density and modulation level.
Together with the automatic composite clipper (always included), Falcon 15 MPX Stereo Coder ensures a
modulation quality much better than that presented by external coders.
The Digital audio input (optional) supports a wide range of numerical formats (including AES3/EBU and
S/PDIF) with several sample rates. Thanks to its automatic recognition of the injected signal and connection type
(optic or coaxial), the Falcon 15 digital input doesn’t require any specific configuration.
The Digital RDS & RBDS coder (optional) provides the services PS, PI, PTY, M/S, AF, RT, DI, TP, TA. Program
service Name (PS) may be broadcast in a sequential mode (up to 8 different words) and with scrolling effect.
RDS programming is achieved through the Pc software which comes with the unit.
The Analog Audio Output provides bi-channel (stereo) audio output electronically balanced on XLR male. It
provides the L and R processed audio signals on which it is possible to enable/disable pre-emphasis. The level is
set via menu.
The Falcon 15 processor comes with Windows software specifically designed for remote monitoring and control
of all the processor sections (from the generation of the MPX signal to the level of AGC), as well as message
editing and enabling RDS services.

11.3 AC CONNECTION
The Falcon 15 uses a power entry module with AC switch just closed to the IEC power
cord receptacle. It can operate on 110 or 240 VAC, 50/60 Hz AC mains voltages. If the unit
is to be used with a mains voltage different to that for which the unit is supplied, set the
voltage change-over switch, which is placed inside the box, closed to the AC transformer.
The power supply socket has an integral fuse drawer containing the AC power fuse and a
spare, both of the same value.
- for 220/230 V AC the fuse is rated at 500 mA T
- for 110/115 V AC tension the fuse is rated at 1 A T
11.4 OUTPUT CONNECTOR
Depending on the version, Output BNC connector (50 Ohm impedance) features Stereo
Composite Signal (MPX) and/or RDS signal (with or without signals injected from Aux 1
and 2 mixed into).
You can adjust the overall
output level through the menu (MPX Level control in the MPX
MODULE SETUP page) in the – 9 dBm to +15dBm range. Factory preset: 0 dBm (2.2
Vpp).
Output connector can provide a reference tone consisting of a 500 Hz / 0 dBm sinusoidal
signal. This tone corresponds to the maximum frequency deviation. To enable it, see par.
12.3.3 .
11.5 SYNC-IN AND SYNC-OUT CONNECTORS
Sync In:
It is disconnected (not used)
Sync Out
This TTL-level (5Vpp) 19 kHz square wave output can be used as the reference signal for
any SCA generator that operates at 57 kHz or other multiple of the 19 kHz pilot frequency.
Using the 19 kHz clock from the Falcon 15 makes it much easier to phase lock the
external signal to the pilot frequency. This is extremely helpful in order to remove
intermodulation
components. For RDS coders, this feature is also very useful.
The Sync Output is disabled
by default (see par. Output Sync menu 12.3.5 for
enabling).
FM VERSION DESCRIPTION ENG
Page 20
11.6 AUXILIARY INPUTS
The Aux inputs allow the Mpx, SCA, RDS injection from external coders. The resultant
signal (f.i. external RDS+ self-generated MPX) is available on the Output connector.
Remarks:
When using an external RDS encoder, the internal RDS one must be disabled.
The level of the injected signal may be adjusted by means of the trimmer next to the
corresponding BNC connector (no software control is provided
for this purpose). This
trimmer is factory preset for a gain of 0 dB.
Suggested RDS injection level is -31.5 dBm (≈ 60mVpp / 2.0 kHz deviation) in relation to
an MPX output of 0 dBm (2.2 Vpp, 0.776 Vrms).
AUX Input impedance is 10 KOhm.
11.7 ANALOG AUDIO INPUT (Female XLR)
Balanced XLR-type connectors are used for input analog audio.
The stereo analog inputs are designed for standard 0 dBu balanced signals. Input level
setting (Sensibility) is done using the software parameter settings (see par. 12.1).
XLR pinout:
Pin 1 Gnd
Pin 2 Signal
Pin 3 Return
In case of unbalanced connections, please connect the cold pole (Pin 3) to the ground (Pin
1).
Factory preset input impedance is 10 kOhm. This impedance may also be set to 600Ohm
by moving the two internal jumpers on the INPUT board (see Chapter 19 - hardware
settings).

11.8 DIGITAL AUDIO INPUT
Transformer balanced XLR-type and optic connectors are used to input AES-3, S/PDIF,
IEC60958, EIAJCP1201 digital audio.
To avoid malfunctions, only one digital connector may be connected at a time. Please keep
the tos-link connector covered while not used.
The digital input accepts any sampling rate between 32 and 96 kHz. No user adjustment is
necessary since a sample rate converter is built into the unit. Furthermore, digital input
automatically recognizes the digital format
(AES, EBU, SPDIF, etc.) and the type of
connection (optic or coaxial).
Even though both analog and digital input audio cables can be connected, only one input
can be set active (analog/digital input selection is done through the software parameter
setting - par. 12.1). Input gain and level setting for digital input is fixed.
XLR pinout: Pin 1 Gnd
Pin 2 Signal
Pin 3 Return
In case of unbalanced connections (as required by S/PDIF format), shortcut pin 3 and 1 or
connect the unbalanced signal to XLR Pin 2 (hot) and Pin 3 (Gnd).
11.9 SERIAL PORTS
Falcon 15 features two optoinsulated RS232 serial ports which allow the remote control
and RDS programming via a connected PC (ref to Chapter 16).
Connect a standard serial cable (not crossed) between the RS-232 connector and a serial
port connector on the computer. Cable length must not exceed 10 mt.
The ports can be separately enabled / disabled via the menu (see par. 12.6.1).
The two serial ports support Tx and Rx signals only. One serial cable comes with the unit.

11.10 DIGITAL DATA PORT
15-pin female Interface connector provides 3 optoinsulated “trigger” inputs.
Split operating mode in response to logic signal transitions.
INPUT 1 is used to carry external network ‘split’ command (ref to Section 13).
INPUT 2 is used to dynamically alter M/S RDS flag. Input enabling will cause LED 2 on
Front Panel to light.
INPUT 3 is used to dynamically alter TA RDS flag. Input enabling enabling will cause LED
3 on Front Panel to light.
The following table displays internal connection of Digital Port and how to provide (f.i.) an external TTL command
to Input # 1.

11.12 FRONT PANEL OPERATION
As described at par. 11.1, Falcon 15 user interface consists of a front panel-mounted jog-wheel, two buttons and
an LCD screen. The LCD screen displays menus, parameter settings and several bargraphs (Level Meters or
processing activity).
The menus are used for the processing parameters adjustement.
Rotating the jog-wheel lets You browse up or down through menus and parameter choices.
Pressing the jog-wheel (called “clicking”) selects the blinking menu item or parameter choice. When editing the
parameter values, rotating the jog-wheel adjusts the parameter’s value up (by rotating CW) or down (CCW).
Once the desired value is reached, clicking the jog-wheel twice saves the value and returns the display to the
upper menu level. You can return to the upper menu without saving by pressing the Esc key or by choosing the
‘Esc’ option.
Thus pressing (or clicking) the jog-wheel serves, depending upon the LCD screen status, as an Enter, Select or
Return command.
Please note that when a new value is only displayed – even blinking – it is immediately loaded into the equipment
processing so that the user can get a real time response.
Enter function is achieved by pressing ‘Enter’ button, too.
Esc/Return function is achieved by pressing ‘Esc’ button, too.
It is useful to remark that you can access all the menu settings and parameters also in a faster and more
confortable way trough the supplied PC control software, which allows an easy and effective remote monitoring
and control, too. When the Falcon 15 control is taken by the PC application in a bidirectional mode (see Chapt.
17), any access to the menu via the front panel keys is not allowed and the message “Remote Pc Host in
Control” is displayed.
NOTE: The front panel menu allows only RDS signal level and status setting. RDS / RBDS messages
programming and all the other related facilities requires the supplied Pc control software – see Chapter 16.
In order to prevent any modification to the Processor configurations, the Front Panel keyboard may be locked
(‘Lock’ procedure is available via the Pc software ).
To save the changes, firstly press Enter to get the Save function and then a second time to confirm
Press Esc to escape the menu without saving and get the upper menu level
Press Esc to get the upper menu level.
