Works properly
Gimzo 09.08.2022
I don't know how to rate this, because you're not buying it if you don't know how it works. So, the unit I got is working properly.

Riktigt bra mixer
Broadcast SWE 16.07.2022
Blackmagic överträffar igen. Riktigt bra mixer med några fler smarta funktioner. Speciellt att man tagit bort att kalla utgångarna för AUX och nu endast Output och dessutom fler utgångar. En annan bra feature är countdown clock som kan läggas på valfri utgång. Men det som kanske är allra bäst att den bara är 1HE.

Der kleine Konferenzheld
PJ-audio 05.05.2023
Ich war lange auf der Suche nach einem Videomischer, der viele Eingänge und viele programmierbare Ausgänge hat.

Grad auf Tagungen wo man mehrere Displays mit verschiedenen Quellen bespielen muss, ist der Constellation 2 M/E perfekt.

Direkter Zugriff über die Tasten ermöglicht schnelles reagieren, sofern man grad keinen Laptop oder ein Advanced Panel zur Verfügung hat.

Wenn man auf einer Tagung noch spontan eine Zoom Schalte oder generell bei einem Hybrid Event zwei Ebenen / Ziele bespielen muss, ist der 2M/E perfekt.

Er bietet alles was man von einem Videomischer erwartet und das zuverlässig und schnell.

Für Konferenzen und Tagungen ist der 2 M/E perfekt sofern man nicht auf eine 4K Auflösung angewiesen ist. Aber wo hängen denn schon 4K Beamer....

Absolute Kaufempfehlung für alle ,deren Setups über einen Atem MIni Extreme pro am Anschlag sind.
