Description

Networkable Amplifiers | Reference: CHADA4B250

Le HADA-4B250 est un amplificateur numérique 4x250W qui prend en charge les charges à faible et haute impédance. Le DSP interne, via le logiciel DSP Manager, permet de personnaliser le signal d’entrée et de sortie via des égaliseurs paramétriques, des compresseurs multibandes, des limiteurs et des délais et chaque configuration peut être enregistrée sous forme de préréglage. En plus de l’option logicielle, les niveaux d’entrée peuvent être contrôlés via les potentiomètres du panneau avant, via des télécommandes à l’aide du GPI du panneau arrière ou via un TCP/IP à partir de systèmes de contrôle tiers. Tous les amplificateurs de la série HADA incluent une protection thermique efficace, une protection CC, une protection contre les surintensités et une protection HF pour une fiabilité totale dans tout type d’installation.

CARACTÉRISTIQUES
