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.

Make sure that the power is switched off and the power cable is disconnected from the equipment.
Open the fuse drawer using a small blade screwdriver.
Replace the fuse located at the inner position
Push the fuse socket back into the original position
Perform the set-up under static control conditions. Static charges are likely to completely destroy
one or more of the CMOS semiconductors employed in the unit. Static damage will not be
covered under warranty.
Basic damage prevention consists of minimizing generation, discharging any accumulated static
charge on your body and preventing that discharge from being sent to or through any electronic
component.
Uninsulated dangerous voltage are inside the enclosure, voltage that may be sufficient to
constitute a risk of shock.
Always disconnect to AC Mains before removing the top cover
9.4 PROTECTION AGAINST LIGHTNING
Should the device be put out of action due to being struck by lightning or excess voltage,
disconnect it from the power supply without delay. Do not reconnect until the device has been
checked. If in doubt contact the technical support service.
Make sure there is suitable lightning protection to protect the device.
Alternatively you should disconnect all connectors from the device during a storm or when the
device is going to be unsupervised or not used for a longer period of time.
These measures will protect against damage by lightning or excess voltage.
9.5 VENTILATION
The equipment will operate as a free-standing unit without requiring any special cooling arrangement.
However, slots and openings in the product are provided for ventilation. They ensure reliable operation of the
product, keeping it from overheating. These openings must not be blocked nor covered during operation.
YOU MUST LEAVE AT A MINIMUM ONE RACK UNIT OF EMPTY SPACE ABOVE THE EQUIPMENT TO
ENHANCE VENTILATION AND TO GET A LONGER EQUIPMENT LIFE.

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).

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).
