Création d’un champ sonore

7Modes DAP (Processeur acoustique numérique) 7 All Channel Stereo

Les modes DAP ont été conçus pour créer les éléments Surround acoustiques importants.

Les sons entendus dans une salle de concert, dans un club de danse, dans un cinéma ou dans un pavillon sont constitués de sons directs et de sons indirects—réflexions premières et réflexions arrière. Les sons directs atteignent directement l’auditeur sans réflexion. Inversement, les sons indirects sont retardés par la distance des murs et des plafonds (voir l’illustration ci-dessous).

Ces sons indirects sont les éléments les plus importants des effets Surround acoustiques. Le mode DAP peut reproduire un champ sonore réaliste en ajoutant ces sons indirects.

Les modes DAP suivants sont fournis avec ce système.

LIVE CLUB: Donne l’impression d’un club de musique à plafond bas.

DANCE CLUB: Rend les sons graves palpitant.

HALL:Éclaircit les voix et donne l’impression d’une salle de concert.

PAVILION: Donne l’impression spacieuse d’un pavillon
