Equipement Son Montreal
Detail du 744T

La prise de son demande aussi un support pour l’enregistrement et Cinéfilms est un des pionniers dans la location d’enregistreur numérique. Nous vous offrons le 744T de Sound Devices, cet enregistreur audio 4 pistes travaille dans le format .wav et ses fichiers audios sont compatibles avec tous les systèmes de montage et les CD. Grâce a son disque dur interne de 80 gigs une production complète peut être archivée pendant des semaines.
