broadcast digital audio processor - profiaudio

DESCRIPTIONFalcon 15 has been refined over a period of years byan experienced team of technicians, psycho-acousticexperts and designers specializing in the development ofprofessional audio equipment based on DSP technologyThe Falcon 15 processing stage provides for analogstereo audio inputs (a digital input is available as anoption). You can choose between two different Output types:analog stereo or composite MPX (i.e. suitable for a directtransmitter connection or a STL radio link).Falcon 15 processing is based on 3 compressors relatedto Bass, Mid and High audio bands. The wide range ofpreset curves and the sophisticated AGC stage allows allusers (even unskilled) to achieve astonishing results fordensity, richness and colour of the sound… An unique‘signature’ for Yr radio sound !DESCRIZIONEIl processore audio Falcon 15 nasce dall’esperienzapluriennale di un team composto da esperti tecniciradiofonici e da progettisti specializzati nello sviluppo d’apparatibasati su tecnologia digitale DSP.La sezione di processamento di Falcon 15 presentaingressi audio analogici di serie (digitali su opzione)mentre l’uscita è, a scelta, di tipo audio bicanale o di tipoMPX composito (adatta, cioè, alla connessione diretta ad untrasmettitore o ad un ponte di trasferimento).Il processamento è basato su 3 compressori operantisulle bande dei Bassi, Medi ed Alti. Grazie all’ampiavarietà di curve preimpostate e ad un sofisticato sistema diAGC, anche l’operatore più inesperto può facilmenteraggiungere risultati sorprendenti in termini di timbrica,corposità, densità… Una ‘firma’ inconfondibile per il sounddella radio!The digital MPX stereo coder (built-in) makesadjustements easy. The Falcon 15’s performance isenhanced by the addition of the Stereo Coder which ensuresthe best ratio between signal density and modulation level.Together with the automatic composite clipper (alwaysincluded), Falcon 15 MPX Stereo Coder ensures a modulationquality much better than that presented by external coders.Digital audio input (optional) supports a wide range ofnumerical formats (including AES3/EBU and S/PDIF)with several sample rates. Thanks to its automatic recognitionof the injected signal and connection type (optic or coaxial),the Falcon 15 digital input doesn’t require any specificconfiguration.Il Codificatore digitale stereo MPX integrato semplificale operazioni di taratura, aumenta le prestazioni di Falcon15 e garantisce un rapporto sempre ottimale tra densità delsuono e livello di modulazione.Unitamente al Clipper automatico integrato, il CodificatoreStereo MPX garantisce perciò una qualità di modulazionesuperiore a quelle ottenibile mediante l’utilizzo di codificatoriesterni.L’ingresso audio digitale (opzionale) supporta una largagamma di segnali (tra cui AES3/EBU e S/PDIF) con variefrequenze di campionamento. Grazie al riconoscimentoautomatico del livello del segnale iniettato e del tipo diconnessione (ottica o coassiale), l’ingresso digitale di Falcon15 non richiede alcuna configurazione manuale.


Digital RDS 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 differentwords) and with scrolling effect. RDS programming isachieved through the Pc software which comes with theunit.The Falcon 15 processor comes with Windows softwarespecifically designed for remote monitoring and controlof all the processor sections (from the generation of theMPX signal to the level of AGC), as well as message editingand enabling RDS services.Il codificatore digitale RDS (opzionale) offre i servizi PS,PI, PTY, M/S, AF, RT, DI, TP, TA. In particolare, il PS puòessere trasmesso anche in forma di sequenza (per un massimodi 8 parole differenti) e in modalità scrolling. Laprogrammazione RDS avviene tramite il software in dotazione.Il software di controllo in dotazione consente ilmonitoraggio, su piattaforma Windows, di tutte le sezionidel processore (dalla generazione del segnale MPX al livellodell’AGC) e la modifica in tempo reale di qualunque parametroe servizio RDS.Examples of typical applications:equipment configuration directly at the transmitting site, forexample by means of a laptop PC• local control via serial cable• Two serial ports optocoupled provide for remote Pc controlor for firmware upgrade (when required).Firmware upgrade may be performed directly by the user.Falcon 15 is available in two versions:• FALCON 15 ST-OUT(featuring processed stereo output only)• FALCON 15 MPX(featuring MPX output only)Optionals (plug-in):For both versions:• digital Audio Input (DG-IN)For MPX version only:• RDS coder• SPLIT circuitEsempi di applicazioni tipiche:configurazione del processore direttamente in postazione,ad esempio tramite un PC portatile• controllo locale via cavo seriale• 2 porte seriali optoisolate offorno la connettività necessariasia per il controllo via Pc che per eventuali aggiornamentidel firmware. Quest’ultima operazione, in particolare, puòessere eseguita direttamente dall’utente finale.Falcon 15 è disponibile in due versioni:• FALCON 15 ST-OUT(con sola uscita Stereo Bicanale)•FALCON 15 MPX (con sola uscitaMPX)Componenti opzionali (plug-in)Per entrambe le versioni:• ingresso Audio Digitale (DG-IN)Per la sola versione MPX:• Coder RDS• Circuito di SPLIT
