Does the QU16 support muting monitors when mic faders are lifted?
Also, is an interface card needed to support AES67/Dante, or will it do it out of the box?

I don’t understand what you trying to do here…

there is no possible support for Dante in the Qu range… have a look at the SQ range instead…

Muting the speakers when the mics are live, so you don’t get feedback from the speakers in certain use cases. It’s an option that you can turn on or off with some mixers.
@bizboz -
Muting mixes when input channels are ‘open’ is not a feature built into the Qu, but can be achieved relatively easily with MIDI.
Using either a translation application on a connected computer (e.g. Bome MIDI Translator Pro – Bome Software ) or hardware that can translate (e.g. BomeBox – Bome Software ) you can use one (just fader) or two (fader and mute) ‘if’ statements to trigger the mute for a mix (or mixes).

RE: Dante - as Steffen says, you’d need to look at the SQ range or above to make use of option cards, but you can use Dante Via with the Qu’s USB audio interface.
