STEREO CODERS
LINEAR stereo coders are equipments designed to offer advanced
stereophonic sound systems, with exceptional performances, for broadcasting
use. They are developed for a very simple and fast integration in existing
LINEAR transmitting systems.
Three different standards stereo coders are available:
1.
BTSC (MTS): is necessary to generate the stereo audio carrier according
to NTSC standard. The system requires only an external composite video
sync reference for locking composite audio carrier. It is equipped in a
10TE plug-in module to be easily allocated in the transmitter EX series.
On request, it could be based in 1HE rack cabinet.
2.
A2 STEREO (common called European): can operate as stereo or dual
sound. It is built in a 10TE plug-in module to be friendly integrated in the
transmitter EX series or allocated in 1HE cabinet, on request.
3.
NICAM: engineered for the professional coding of audio signals to the
digital NICAM 728 TV stereo sound signals. The IF output signal is
combined with the IF coming from a TV analog modulator. It is assembled
in 1HE cabinet.
I codificatori stereo LINEAR sono dispositivi per uso broadcast progettati per offrire
sistemi audio stereofonici avanzati e con prestazioni eccellenti, realizzati per una
semplice e veloce integrazione nei sistemi di trasmissione LINEAR già esistenti.
Sono disponibili in tre diversi standard :
1.
BTSC (MTS): indispensabile per generare la portante audio stereo conforme
allo standard NTSC. Il sistema necessita di un riferimento esterno (composite
video sync) per agganciare la portante audio composita. Il dispositivo può
essere realizzato in un modulo plug-in da 10TE per essere facilmente integrato
nei trasmettitori della serie EX, oppure, su richiesta, allocato in unità stand
alone da 1HE.
2.
A2 STEREO (comunemente chiamato Europeo): può operare come stereo o
dual sound. Anch’esso è disponibile sia nella versione in un modulo plug-in
10TE per essere facilmente integrato nei trasmettitore della serie EX, oppure,
su richiesta, in un rack 1HE.
3.
NICAM: progettato per la codifica professionale di segnali stereofonici nel
segnale stereo digitale NICAM 728 TV. Il segnale di uscita IF è combinato con
l’IF proveniente da un modulatore analogico. Il codificatore è allocato in un
rack 1HE.
Los codificadores estèreo LINEAR estàn diseñados para ofrecer sistemas
avanzados de sonido estereofònico, con rendimientos excepcionales, para
radiodifusiòn. Se desarrollan para una integración muy simple y rápid en los
sistemas existentes de transmisión LINEAR Italy.
Hay disponibles tres diferentes estàndares:
1.
BTSC (MTS): es necesario para crear la portadora de audio estèreo de
acuerdo con el estándar NTSC. El sistema require sòlo una referencia
externa (composite video sync) para el bloqueo de la portadora de audio
compuesta. Està equipado en un mòdulo de enchufle de 10TE para ser
puesto fàcilmente en un transmisor serie EX. A petición, puede basarse
en el bastidor de 1HE.
2.
A2 STEREO (común llamado European): puede funcionar como un
sonido estéreo o doble. Està construido en un mòdulo enchufle de 10TE
para ser integrado con facilidad en la serie de transmisor EX o asignado
en el rack de 1HE.
3.
NICAM: está diseñado para la codificaciòn profesional de señales de
audio en señales de sonido estéreo de TV NICAM 728. El señal FI de
salida se combina con la entrada FI de un modulador de televisión
analógica. Se monta en el chasis de 1HE.
