IN & OUT SETTINGS (MPX VERSION) FALCON 15 - ENG 4 IN & OUT SETTINGS (MPX VERSION) Once the unit is installed, here’s the procedure to get your Falcon 15 operating properly using factory presets. With proper calibration the Falcon 15 will give you the most accurate results for peak control and modulation. Take the time to go through the steps laid out in this chapter! 4.1 HOW TO CONFIGURE THE INPUT (INPUT SETUP) 4.1.
IN & OUT SETTINGS (MPX VERSION) 4.1.3 FALCON 15 - ENG CHOOSING THE PROPER AGC OPERATION One of the most important processor function is the Automatic Gain Control (AGC) system, which compensates for variations in the input level to keep the signal at 0 dB.
IN & OUT SETTINGS (MPX VERSION) FALCON 15 - ENG We suggest using medium levels of around 2 ÷ 3 dB / sec, and especially that you concentrate on the audio sources connected to the processor, to obtain the most even sound possible. NOTE: The processor features a phase rotator input stage, also called ‘Voice Optimizer’ that is always kept active. It is a special all-pass filter designed to properly modify input signal waveform in order to avoid unpleasant effects in the processing of ‘live speech’ material.
IN & OUT SETTINGS (MPX VERSION) FALCON 15 - ENG 4.2 HOW TO CONFIGURE THE MPX OUTPUT (MPX MODULE SETUP) 4.2.1 SETTING THE PREEMPHASIS The Mpx Module Setup / Preemphasis menu toggles between 50uS and 75uS of preemphasis applied to the Falcon 15’s MPX output. European countries use a 50 uSec preemphasis, while US countries use a 75 uSec preemphasis.
IN & OUT SETTINGS (MPX VERSION) 1 Escape from the Output Level menu and enter the Output Mode menu. 2 Select the Peak Reference Tone option. FALCON 15 - ENG The Peak Tone identifies the maximum peak value of the audio and MPX signals reached by the processor while it is operating. This peak corresponds to the maximum frequency deviation. This allows you to set the levels for the entire sound chain simply and safely.
IN & OUT SETTINGS (MPX VERSION) 4.2.6 FALCON 15 - ENG NOISE GATE SETTING (Noise Gate) The Mpx Module Setup / Noise Gate function allows you to avoid the effects of background noises while the input signal presents a lack of high frequencies. The parameter to be set is the Noise Gate Threshold, which determines the threshold value below which the dynamic pre-emphasis is automatically excluded. The Noise Gate Threshold: This may be adjusted within a range of –80 to –51dB (1 dB steps).
IN & OUT SETTINGS (MPX VERSION) 4.3 FALCON 15 - ENG HOW TO CONFIGURE THE RDS OUTPUT (RDS MODULE SETUP) The processor generated RDS signal** can be adjusted by means of the RDS Module Setup menu. A RDS Encoder menu allows You to turn the encoder On and Off. The RDS signal Level may be adjusted within the deviation range. Here below are presented some relations between deviation and RDS signal level: -37.5 dB -31.5 dB -28 dB -25.5 dB -23.5 dB -21.9 dB D=1.0 KHz D=2.0 KHz D=3.0 KHz D=4.0 KHz D=5.0 KHz D=6.
IN & OUT SETTINGS (MPX VERSION) 4.4 FALCON 15 - ENG SETTING THE SPLIT MODES The MPX SPLIT mode allows Falcon 15 Output to toggle between an external MPX signal applied to AUX 1 input and the MPX signal internally generated (see Switch SW1 and SW2 here below).

CHOOSING THE PROCESSING CURVE FALCON 15 - ENG 7 CHOOSING THE PROCESSING CURVE 7.1 INTRODUCTION Once you have adjusted the input levels and reached the correct AGC level, you may move on to select the processing curve. There are 30 factory presets designed for various programming formats. Chose one that approximately matches your station’s format. If you are not sure, chose Preset # 25 and 26 to achieve best results for density, richness and colour of the sound.
CHOOSING THE PROCESSING CURVE 7.
CHOOSING THE PROCESSING CURVE 7.3 FALCON 15 - ENG CHOOSING A CURVE As already explained in other sections of the manual, the DSPs in the processor implement three compressors, which affect the 3 bands: Bass, Mid and High. The three meter bars displayed on the front panel indicate the level of compression exerted on each frequency (in other words, the more notches shown, the more the corresponding frequency is compressed, and thus the less will be audible).

THE REMOTE PC CONTROL SOFTWARE 8 8.1 FALCON 15 - ENG THE REMOTE PC CONTROL SOFTWARE INTRODUCTION The Falcon 15 (ST-OUT and MPX versions) comes with a powerful and reliable software running on all Microsoft Windows o.s. (’95, ’98, ME, 2000, NT and XP) and specially conceived for equipment programming and control. It allows either the visualization in real time of the equipment current configuration or its modification by means of a Bidirectional (i.e. local) serial link.
THE REMOTE PC CONTROL SOFTWARE 8.3 FALCON 15 - ENG RUNNNING THE PROGRAM Open the software from Start ➜ Programs ➜ Axel Falcon 15 vers X.Y (or C:/programs/ Axel Technology / Falcon 15 Audio processor versX.Y). The computer screen should resemble the image below: 8.4 CLOSING THE PROGRAM Click the box X in the upper, right hand corner of the screen. Escting the program does not alter Falcon 15 operation. 8.
ACCESSING THE TARGET FROM THE PC FALCON 15 - ENG - The Output page includes the controls for the functions: MPX Output Level, Audio Output Level, Preemphasis, Noise Gate, Output Mode, Output Sync and Input Mode (Stereo/Mono). These controls may ba disabled, according to Yr Falcon 15 version (ST-OUT or MPX).
ACCESSING THE TARGET FROM THE PC 9.1 THE SETUP PANEL 9.1.1 SELECTING THE PC SERIAL PORT FALCON 15 - ENG First of all, it is necessary to indicate which computer serial port is dedicated to the communication with the processor (COM 1, 2, 3 or 4). Once a port is assigned, click ‘Connect’ buton to attempt the connection to the processor. • If the serial port selected is physically present on the computer but is not connected to the processor, the control program will display ‘Remote Data not Available’.
ACCESSING THE TARGET FROM THE PC 9.1.2 FALCON 15 - ENG OTHER SETTINGS It is now possible to set up or modify some modes regarding the software window display on the computer screen, and communications between the computer and the processor. • If selected, the option ‘Always On Top’ will always keep the control program window in the foreground of the desktop. • If selected, the option ‘High Rate’ allows you to select the higher refresh speed (30 Hz) in displaying the Vu Meter on the screen.
RDS SETTINGS (MPX Version only) FALCON 15 - ENG 10 RDS SETTINGS (MPX Version only) 10.1 INTRODUCTION The processor includes, as an option, a complete RDS encoder, programmable by a PC connected to its Serial Ports. The RDS section controls (for RDS messages and other services) are accessible only via the remote control software supplied with your processor. Please refer to the previous chapter for installation & setup procedure instructions for this software. 10.
RDS SETTINGS (MPX Version only) FALCON 15 - ENG 10.3.1 RDS SERVICES DESCRIBED PI - Programme Identification It contains four hexadecimal numbers ( see ‘Code’ box ): the first one assigns the broadcast country and it is automatically provided from the application by clicking the country acronyms (see Country Group). The second hexadecimal number assigns the coverage area profile ( i.e. national , local etc.
RDS SETTINGS (MPX Version only) 10.4 FALCON 15 - ENG PROGRAM SERVICE NAME (PS) 10.4.1 SCOPE The PS feature is intended to denote the Program Service Name. This name is not dynamic in nature but it can changed when necessary. The difference between the implementation of the PS and RT features is that the PS is always displayed on the receiver, while the RT message will be displayed only when the listener deems it safe to do so. Dynamic PS may be a distraction to the drivers.
RDS SETTINGS (MPX Version only) FALCON 15 - ENG 10.4.3 PS SEQUENCES Falcon 15 allows You to easily create and broadcast sequences composed by up to 8 PS Names. You can also set the ‘display speed’ (related to the time it will last on the receiver display). Having filled the fields PS 1, PS 2 , etc, to create a PS sequence You have just to select the last item of it, as the first item is set by default (PS 1). Different ‘display rate’ can be set for al the messages.
RDS SETTINGS (MPX Version only) FALCON 15 - ENG 10.4.4 PS SCROLLING PS Scrolling panel allows You to enter PS message which will scroll on the receiver display. It means, text is moved right to left across the display one character at a time at the rate set by the user (SPEED). Max lenght: 32 characters. WARNING: if the PS is constantly changed (as in the PS Scrolling mode), it is possible that some receivers will display a mixture of old and new PS message on the same display.
RDS SETTINGS (MPX Version only) 10.5 FALCON 15 - ENG ALTERNATIVE FREQUENCIES The list(s) of alternative frequencies give information on the various transmitters broadcasting the same programme in the same or adjacent reception areas, and enable receivers equipped with a memory to store the list(s), to reduce the time for switching to another transmitter. This facility is particularly useful in the case of car and portable radios.
RDS SETTINGS (MPX Version only) 10.6 FALCON 15 - ENG AF METHODS A AND B There are two ways to transmit lists of alternative frequencies: Method A and Method B. In both cases the lists should include only those frequencies for the nearest transmitters and repeaters (with overlapping coverage areas). Generally speaking, Method A is used when the list contains no more than 25 frequencies, and Method B when the list is longer (for a maximum of 24 lists).
RDS SETTINGS (MPX Version only) Tx B lists (tuning frequency: f Tx B) Tx D lists (tuning frequency: f Tx D) AF1 AF2 f Tx B f Tx D f Tx D f Tx B AF1 AF2 AF3 f Tx D f Tx B f Tx E f Tx B f Tx D f Tx D FALCON 15 - ENG Note that the frequency of transmitter C is not included in the list, since the latter’s coverage area does not overlap with that of transmitter A Coverage area D partially overlaps that of both transmitters B and E, and thus it is recommended to load the lists for both adjacen
RDS SETTINGS (MPX Version only) FALCON 15 - ENG Returning to the example of transmitters B, D and E in the previous paragraph (in which the coverage areas of D and E do not overlap), two more lists will be assigned to transmitter B, sorted according to the above criteria to take into account any different programming by some of the AFs.
HARDWARE SETTINGS FALCON 15 - ENG 11 HARDWARE SETTINGS 11.1 CHANGING THE INPUT AUDIO IMPEDANCE (MPX VERSION) The analog input impedance may be set to 600Ω, rather than 10kΩ, by moving the two jumpers JP1 and JP2 on the analog input board (see figure below). 11.2 CHANGING THE INPUT AUDIO IMPEDANCE (ST-OUT VERSION) The analog input impedance may be set to 600Ω, rather than 10kΩ, by moving the two jumpers J6 and J7 on the analog input board (see figure below) to the right-hand position.
