We used many digital mixers with battery-backed RAM memories in the past and there was no shutdown problems by hard power off.
AH has a different storage concept, which requires a shutdown, that no data were damage by switching off.
For fixed installation we need clearly switched on and off sequences for all system components. The power on procedure starts with real mains power on of multi track wave player and wireless mics -> mixer -> power amp 1 -> power amp x, step by step. The power off procedure will happens in reverse line. This part will executed by an external control device. Unfortunately, it is not possible to shut down the SQ5 remotely yet, only manually on the console. When using the system without specialist operators or the SQ5 is mounted in a closed rack, so it would be good to have a remote hardware input or a MIDI command for remote shutdown.
