ENG GENERAL DESCRIPTION 14 GENERAL DESCRIPTION 14.
GENERAL DESCRIPTION ENG 12 ANALOG AUDIO OUTPUT: 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. 13 ANALOG AUDIO INPUT: bi-channel audio input electronically balanced on XLR female. The input level is set via menu. An hardware bypass directly connect the two input XLRs to the output ones in the event of power failure or processor switched off.
GENERAL DESCRIPTION ENG 14.3 DISPLAY DESCRIPTION 1. ON AIR Preset: shows the current processing curve. The presets ranging from 1 to 30 are factory preset, while curves 31 to 40 are user settable. A table showing the curve parameter levels is available on this manual. 2. AGC level: shows the gain factor that the processor applies to the input signal. The best AGC values range close to 0 dB (or, still better, are slightly negative: - 1, - 2, etc). 3. Low frequencies compression factor (30Hz-200Hz band).
GENERAL DESCRIPTION ENG 14.4 LCD BACKLIGHT CONTROL As factory preset, the LCD backlight is automatically turned off in the event the front panel controls (shuttle and buttons) are left untouched for 5 minutes. If permament backlight is needed, move the jumper J9 located on the front panel board towards the mother boards.
AUDIO I/O AND SERIAL PORT WIRING ENG 15 AUDIO I/O AND SERIAL PORT WIRING 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 pick-up. Check the cables for correct wiring to avoid problems with phase reversal and unreliable connection. 15.
AUDIO I/O AND SERIAL PORT WIRING ENG 15.2 DIGITAL AUDIO INPUT * The digital input (available only as an option - DG-IN) 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/P DIF signals (“consumer standard” interface).
ENG AUDIO I/O AND SERIAL PORT WIRING 15.3 DIGITAL AUDIO OUTPUT ** The digital output features two connectors: coaxial and optic. Only one connector may be connected at a time to avoid malfunctions. The output format is AES3/EBU with sample rate 48KHz, 24 bit. 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 noise (EMI). Pin 1 Pin 2 Pin 3 13 2 Gnd Signal Return.
AUDIO I/O AND SERIAL PORT WIRING ENG 15.5 SERIAL PORTS The processor features two optoisolated serial ports for remote control through PC (connected directly or via satellite chain) of all machine functions and parameters. A standard, not crossed serial cable (9p male – 9p female) is provided with the equipment, compatible with all configurations.
MPX BOARD CONNECTIONS (FM VERSION ONLY) ENG 16 MPX BOARD CONNECTIONS (FM VERSION ONLY) Available as an option on the FM version, the MPX board supports many configurations and operation modes.
MPX BOARD CONNECTIONS (FM VERSION ONLY) ENG 16.
MPX BOARD CONNECTIONS (FM VERSION ONLY) ENG 16.2 DEFAULT MPX BOARD CONFIGURATION (FM-MPX VERSION ONLY) When not otherwise specified, the MPX board comes with J2, J4 and J5 jumpers closed and with OUT-2 output disabled. The AUX 2 input (BNC connector, 10 kOhm impedance) allows an external signal (tipically RDS) from an external encoder to be injected on the MPX output of the processor. The level of the injected RDS signal may be adjusted by means of the trimmer next to the corresponding BNC connector.
ENG THE ‘SPLIT’ MODE (FM VERSION ONLY) 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 menu (Optional Controls / MPX Mode / Sync Out).
ENG THE ‘SPLIT’ MODE (FM VERSION ONLY) 17.1 HOW TO ACTIVATE THE ‘SPLIT’ MODE (FM VERSION ONLY) The ‘Split’ mode (available as an option) is activated through a dedicated input on the OPTO INTERFACE port. The OPTO-INPUT Port is a 9-pin female Interface (on DB-9 connector) which provides 2 optoinsulated “trigger” inputs: one for SPLIT mode activation and one for TA flag switching. Once enabled, SPLIT activation will cause SPLIT LED on rear panel to light.

I/O CALIBRATION AND SYSTEM SETUP ENG 19 I/O CALIBRATION AND SYSTEM SETUP The processor is designed for easy installation and set up. All necessary interface connections are made through rear panel connectors. Refer to Rear Panel Connectors Chapter for a description and placement of each of the connections. With proper installation and calibration the processor will give you the most accurate results for audio processing and modulation.
I/O CALIBRATION AND SYSTEM SETUP ENG 19.2 ANALOG INPUT LEVEL ADJUSTMENT Skip this step if you are not using the analog inputs. This step calibrates the analog inputs to the level at which your studio system peaks its program material on the studio meters. This assures that the processing presets will operate in their optimal range. To take full advantage of the processor potential, the AGC value should normally operate in compression mode (meaning that it slightly reduces the input level).
I/O CALIBRATION AND SYSTEM SETUP ENG 19.3 MONO / STEREO INPUT OPERATION (ST VERSION ONLY) The ‘INPUT MODE’ menu selects the mono versus stereo operation of the input. You can chose between a full stereo operation or a Mono mode where Left and Right input channels are mixed together before going through the main processing stages. NOTE: In the MONO L+R Mode, either the L or the R output will provide the L+R sum. DEFAULT SCREEN INPUT CALIBRATION menu INPUT MODE page 19.
I/O CALIBRATION AND SYSTEM SETUP ENG The Phase Rotator stage performs 1 msec Group Delay at low frequencies in respect of medium frequencies. This results in a phase rotation centered on 600 Hz frequency. 19.5 AGC SPEED 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.
I/O CALIBRATION AND SYSTEM SETUP ENG 19.6 AGC MODE The AGC Mode menu mainly serves to regulate the maximum level gain recoverable by the AGC (MaxGain) and its intervention time (with reference to the interval –3 to 3 dB within which the AGC works at one quarter of the user-set speed).ȱ < DEFAULT SCREEN < INPUT CALIBRATION menu AGC Mode The Hold parameter allows you to define the time the AGC system has to wait before intervening when the signal varies.
ENG I/O CALIBRATION AND SYSTEM SETUP 19.7 ANALOG OUTPUT PRE-EMPHASIS The XLRs analog output is intended for applications requiring discrete L/R processed audio. The frequency characteristic can follow a selected pre-emphasis curve, with or without subsequent de-emphasis. The factory-default setting is with pre-emphasis engaged, accordingly to the destination country (50 or 75 uSec).
ENG I/O CALIBRATION AND SYSTEM SETUP Remarks: Only one pre-emphasis must be kept active in a transmitting chain. It is highly recommended to use the pre-emphasis within the processor and turn off the one generated by external TX or MPX Coders. The processor’s pre-emphasis may be disabled on the analog audio outputs, but NOT on the MPX output, which remains 50 or 75 uSec pre-emphasized at all times. - European countries use a pre-emphasis time of 50 uSec. 19.
I/O CALIBRATION AND SYSTEM SETUP ENG 19.9 ANALOG OUTPUT LEVEL You can adjust the analog audio output level (XLR connectors) through the Output Level control: DEFAULT SCREEN OUTPUT CALIBRATION menu OUTPUT LEVEL page The Output Level parameter expresses the peak value (in dBu) achieved by the audio output signal (which therefore corresponds to the maximum frequency deviation). To set the optimum audio output level, it is advisable to enable the Peak Reference Tone.
I/O CALIBRATION AND SYSTEM SETUP ENG 19.11 MPX OUTPUT LEVEL (FM VERSION ONLY)* The MPX signal (+ any internally or externally generated RDS signal or SCA signal) is available on the Bnc MPX OUT connector. * the MPX module is available as an option The MPX output may be tuned using the small trimmer located next to the output BNC. In order to best adjust the output level, we recommend enabling a pilot tone (see paragraph 20.7), which identifies the maximum peak which match the deviation of 75 KHz.
I/O CALIBRATION AND SYSTEM SETUP ENG 19.12 MPX OUTPUT PREEMPHASIS (FM VERSION ONLY)* The Mpx output is with pre-emphasis always engaged, accordingly to the destination country (50 or 75 uSec).
I/O CALIBRATION AND SYSTEM SETUP ENG 19.14 RDS SIGNAL LEVEL CONTROL (FM VERSION ONLY) *** The processor generated RDS signal level and phase can be adjusted by means of the RDS Module menu. DEFAULT SCREEN OPTIONAL CONTROLS menu RDS MODULE menu RDS LEVEL (or RDS PHASE) The RDS signal Level may be adjusted within the deviation range of 1.0 to 6.0 kHz (default operating level: -31.5dB, D=2.0 KHz). The relation between deviation and level is as in the following table: -37.5 dB -31.5 dB -28 dB -25.5 dB -23.
I/O CALIBRATION AND SYSTEM SETUP ENG 19.15 POWER LIMITER CONTROL ITU 412 (ST VERSION ONLY) 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.
I/O CALIBRATION AND SYSTEM SETUP ENG For instance: Output mode Limiting threshold RDS signal not available Mono signal (no Pilot available) Mono signal (no Pilot available) + RDS + 0.25 dBITUref +1.0 dBITUref +0.75 dBITUref For better results, we recommend to use the Equalization Presets 29 and 30 (labeled as ITU), as they have been especially designed to keep the output power as much constant as possible. As expected result, the power level will always range by less than 0.
ADDITIONAL SETUP TASKS ENG 20 ADDITIONAL SETUP TASKS 20.1 SERIAL PORT ENABLING (SERIAL MODULE) The Serial Module menu visualizes the status of the two serial ports RS 232 allowing their enabling or disabling. Remarks: - Ports are enabled by default (factory preset). - Firmware upgrade and remote control are possible only with enabled ports.
ADDITIONAL SETUP TASKS ENG To save a new setting, press Enter twice. Press Esc to exit without saving any changes. Press Esc again, or select the Quit option on the display, to return to the next higher menu layer. 20.3 NOISE GATE SETTING (NOISE GATE) The Noise Gate function allows you to avoid the effects of background noises while the input signal presents a lack of high frequencies.
ADDITIONAL SETUP TASKS ENG 20.4 READING OUT THE FIRMWARE CODE The Firmware Code menu page displays the internal firmware serial code. The user must supply this number to the manufacturer in order to upgrade the processor firmware or add the RDS option. 20.5 READING OUT THE INTERNAL TEMPERATURE The Temperature sub-menu shows the internal temperature of the processor during operation. - The current temperature is updated each time this option is accessed.
ADDITIONAL SETUP TASKS ENG 20.7 CHANGING THE OPERATING MODE (OUTPUT MODE) The Output Mode function allows you to select from among three different equipment operating modes: - Normal operation Peak Reference Tone Processor ByPass The Normal operation allows normal use of the equipment and all of its functions.
CHOOSING THE PROCESSING CURVE (FM and ST) ENG 21 CHOOSING THE PROCESSING CURVE (FM and ST) 21.1 INTRODUCTION Once you have adjusted the input levels and reached the correct AGC level, you may move on to select the processing curve. The processor has 40 curves: the factory presets (PR) are stored in positions 01 through 30, while positions 31 to 40 may be set by the operator. As shown in the table on the next page, there are 10 parameters involved in processing.

CHOOSING THE PROCESSING CURVE (FM and ST) ENG The following processing parameters may be adjusted. • Super Bass Level • Super Bass Type The Super Bass Type parameter sets the type of bass added to the sound by the Bass Enhancer. The Bass Enhancer takes the bass signal from the 30Hz-200Hz range, and generates subharmonics that are filtered and modeled by the Super Bass Type, then once again injected onto the bi-channel signal at the level set via the Super Bass Level control.
CHOOSING THE PROCESSING CURVE (FM and ST) ENG parameters. • Wide Density The Wide Density parameter adjusts the compression level throughout the band, increasing the average signal level (while reducing dynamics). The frequency deviation remains within 75 KHz. Wide Density may be adjusted from 0.0 to +12.0 dB, with steps of 0.5 dB. High density values provide the transmitted signal with a strong ‘presence’, while reducing the dynamics of the signal.
CHOOSING THE PROCESSING CURVE (FM and ST) ENG There are two ways to design or customize a curve: A. From among the existing curves, identify the one closest to the desired curve, make the changes deemed appropriate (for example, raise the level of mid tones or cut out low frequencies) and save the new curve thus obtained in one of the 10 locations set aside for the user (31 through 40). B.
CHOOSING THE PROCESSING CURVE (FM and ST) ENG Once you have finished choosing all the new levels: - turn the shuttle counter-clockwise until you see the ‘Get Process’ item again keep turning the shuttle until the item ‘Quit’ appears on the left press ‘Enter’. At this point the menu displays the item ‘Editing To TrashCan’ - when this option is selected with ‘Enter’, the changes made up until that moment will not be saved, and will be lost.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22 THE PC CONTROL SOFTWARE (FM and ST versions) 22.1 INTRODUCTION The processor comes with a intuitive and reliable software running on Windows 95, 98, NT, ME, 2000, XP platforms and specially designed for remote / direct equipment programming and control.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22.2 BIDIRECTIONAL MODE (DIRECT CONTROL) On the rear panel of the processor are two serial ports for interfacing to IBM-compatible PCs. SERIAL 1 BI-DIRECTIONAL CONNECTION - DIRECT SOFTWARE CONTROL - FIRMWARE UPGRADE PC CONTROL SOFTWARE The picture shows the bidirectional (or local) connection mode between the processor and a regular Windows Pc. This connection mode allows both real-time display and editing of the current processor configuration.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22.3 MONO-DIRECTIONAL MODE (REMOTE) SERIAL 2 given Target & Group name UNIDIRECTIONAL CONNECTION (SATELLITE, RADIO LINK, STL, ISDN, ETC) PC CONTROL SOFTWARE The picture shows the mono directional connection mode, which does not involve any return channel. It is possible to send commands to the equipment from remote sites, but does not allow either remote monitoring of the machine, nor confirmation of control reception.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22.4 INSTALLATION A) Using standard Windows procedures, access the PC REMOTE SOFTWARE folder and run the SETUP.EXE file under the Microsoft Windows® ’95, ’98, ME, 2000, NT and XP operating system. B) The install program installs Pc remote Control application onto the computer's hard disk. The installation screen will also suggest a destination directory for the software.
ENG THE PC CONTROL SOFTWARE (FM and ST versions) 22.5 SOFTWARE SETUP Run the program. If it is unable to immediately establish an bidirectional connection with the processor, (as indicated by the display message ‘Remote data not Available’), a screen such as the following will appear: Click the ‘Setup’ key, and the following screen will appear: First of all, it is necessary to indicate which computer serial port is dedicated to the communication with the encoder (COM 1, 2, 3 or 4).
ENG THE PC CONTROL SOFTWARE (FM and ST versions) NOTE: the program will automatically attempt the connection each time you run the SETUP screen. 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.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22.8 SAVING THE CURRENT CONFIGURATION Any operative configuration of the processor (input gain, pilot level, RDS messages, enable status of RDS services, etc.) may be saved at any time. To do so, simply press the ‘Save’ button and indicate the name with which to save the configuration (for example, the operator’s name). Note that the preset (processing curve) broadcasting is not included in this saving operation. 22.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22.10 BI-DIRECTIONAL CONNECTION MODE As explained earlier, this mode (available only on port 1 of the processor) allows both the real time display and editing of all audio levels and current settings for all parameters used by the processor. Typical application: setting the processor directly at the transmitting site, using a notebook computer, or remote control from the broadcasting or control room, via serial cable.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22.11 THE ‘TARGET NAME AND GROUP NAME’ IDENTIFIERS As explained in the introduction, in bidirectional connection mode (local) it is possible to assign each processor with a specific identification code (called the ‘Target Name’), as well as a classification group, which is useful when you wish to selectively program the processor from remote sites over a unidirectional connection (see next chapter).
THE PC CONTROL SOFTWARE (FM and ST versions) ENG 22.13 UNIDIRECTIONAL CONNECTION MODE The unidirectional connection mode is used to control one or more processors from a remote site, for example over a satellite link. In this case, it will only be possible to send commands or new values for operating parameters one way, without the ability to check whether the change has taken place or the current status.
THE PC CONTROL SOFTWARE (FM and ST versions) ENG Once the remote connection (on serial port 2 of the processor) has been established, the basic screen of the control software will be as follows: The submenus available are the same ones available with the bidirectional connection, thus: - The three buttons located alongside the display allow you to edit the new broadcast processing curve: select the curve from among the 40 available, using the two arrows, then confirm the choice using the rectangular but
Using the RDS SECTION (FM version ONLY) ENG 23 USING THE RDS SECTION (FM version ONLY) The processor includes, as an option, a complete RDS encoder, programmable by a PC connected to its Serial Port 1 (bidirectional) or Serial 2 (monodirectional). This allows you to install encoders throughout the network, including local stations, and set them using a ‘master’ PC. The RDS upgrade procedure, if the RDS plug-in is not already present in your processor, is explained in one of the next chapters.
Using the RDS SECTION (FM version ONLY) ENG 23.2 RDS SERVICES - QUICK SUMMARY PI The PI code consists of four hexadecimal digits (see ‘Code’ field). The first identifies the country where the program is transmitted, the second digit identifies the type of broadcaster based on coverage area. Finally, the ‘Ref’ window must contain a number between 1 and 255 (normally assigned by the authorities).
ENG Using the RDS SECTION (FM version ONLY) 23.3 TA REMOTE CONTROL TROUGH OPTO INTERFACE The TA flag may be activated through a dedicated input on the OPTO INTERFACE port (the interface is available as an option). The OPTO-INPUT Port is a 9-pin female Interface (on DB-9 connector) which provides 2 optoinsulated “trigger” inputs: one for SPLIT mode activation and one for TA flag switching. Once enabled, TA input activation will cause WARNING LED on Front Panel to light.

To transmit scrolling messages: 1) type the text to be scrolled directly into the field at the bottom (PS Scrolling).
Using the RDS SECTION (FM version ONLY) ENG 23.7 HINTS AND TIPS ABOUT DYNAMIC PS MODE When programming PS durations in Dynamic mode, two ‘gold’ rules should be taken into account. They are related to the ‘physics’ of RDS channels and are completely independent from RDS encoder architecture. 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.
Using the RDS SECTION (FM version ONLY) ENG 23.8 ALTERNATIVE FREQUENCIES LIST 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.
Using the RDS SECTION (FM version ONLY) ENG 23.9 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).
Using the RDS SECTION (FM version ONLY) ENG METHOD B As mentioned earlier, Method B is used with high numbers of alternative frequencies and/or when the transmitter also has frequencies that broadcast different radio program at various times of day (splitting, local programming, etc.). In the latter instance, the mobile receiver should check whether the AF is broadcasting the same content before selecting another frequency.
ENG Using the RDS SECTION (FM version ONLY) 23.10 HOW TO GET IT The RDS option could be pre-installed in the factory if notified when ordering the unit or it can be installed at the customer’ premise after receiving it. In the latter case, the RDS software must be activated with a proper Activation Key, uniquely determined by your unit firmware's serial number.
FIRMWARE UPGRADE ENG 24 FIRMWARE UPGRADE The processor comes from the factory with the most recent firmware installed just prior to shipping. When required, the firmware can be updated with the latest available version using standard Windows procedures. After an initialization of the device (firmware upgrade), all user presets and adjustments are erased and/or overwritten by the new factory setup! Please make a note of Yr current, customized software presets before proceeding with the firmware upgrade.
ENG FIRMWARE UPGRADE E) Turn the processor on. 2) RUNNING THE UPGRADE FILES ON THE PC G) Close all opened applications on the PC.
FIRMWARE UPGRADE ENG The following screen will be displayed: J) Select the PC serial port on the screen K) Click Request button. L) Make sure the Identification is correctly done (Processor Identification passed message + firmware code displayed in the right field), and click ‘UpGrade’. The upgrade will continue automatically. NOTE: the upgrade processing must not be interrupted. M) Once you have completed the upgrade procedure, shut off the equipment.
FIRMWARE UPGRADE ENG With RDS option NOT installed, the processor will display the message ‘RDS DEMO SIGNAL’ when accessing the Optional Controls/RDS Module/RDS Level menu. With the RDS option correctly installed, the processor will display the message ‘RDS SIGNAL’ when accessing the Optional Controls/RDS Module/RDS Level menu. IN CASE OF FIRMWARE VERSIONS FORMER TO 2.0 (FM version only) In case of firmware versions former to 2.
