We use a Yamaha O3D, a little overkill for just monitoring, but all our suites have the same audio-setup, and this mixer was not being used at the time the 844 was installed. It works great though, plus it provides all kind of flexibility to connecting to a lot of analogue and digital equipment wiithin our facility.
