Für "wenig" Geld solide Grundausstattung für Live Schnitt
ClemensMediaProductions 22.11.2022
Ich will mich beruflich auch mehr in Richtung Live Events Live Schnitt Live Stream und dergleichen bewegen. Der Constellation HD 1 M/E hat quasie alle Features die High End Mixer von Blackmagic haben, aber alles kleiner Kompakter und statt Hausnummer 40 Eingängen eben "nur" 10. Für mich perfekt. Ich kann alles proffesionell umsetzen was ich möchte, der mixer funktiniert einfach. Und ich hab dafür kein Vermögen investieren müssen.
