Neumann KH 750 DSP – Caisson
Neumann KH 750 DSP est un caisson de basses actif à DSP, haut-parleur 10″, 48,4 litres, 256 W, 105 dB SPL, 18–300 Hz. Le DSP compact KH 750 est le choix idéal pour les petites salles et les petits moniteurs de studio. Il dispose d’un gestionnaire de basses unique et flexible (2.0/0.1), d’entrées analogiques et numériques, de quatre modes de routage et de commandes acoustiques adaptables à utiliser dans de nombreuses configurations différentes.
En plus de ses propriétés acoustiques exceptionnelles, Neumann KH 750 DSP basé sur DSP offre des fonctions pour les moniteurs Neumann connectés à ses sorties concernant l’interaction avec les outils suivants :
– Alignement automatique du moniteur – Correction automatique de la pièce des systèmes stéréo à l’aide du microphone de mesure Neumann MA 1 (logiciel pour Mac/PC)
– Neumann.Control – Application iPad® gratuite pour la configuration, le fonctionnement et la correction de pièce des systèmes stéréo via un alignement guidé et/ou manuel
