Power on/off sequence,
always turn the power amps on last and turn them off first. In both cases leave at least a minute between them and anything else in the rig.
My DL power on sequence is :-
1, plug desk/router in (this powers the router as it's in a box with the desk sharing single IEC connector)
2, wait 1-2 mins then switch on DL1608 (iPad un-docked and off)
3, wait 1 min then dock iPad #1 (iPad will now power itself on)
4, start MF and go to settings and check DL1608 connected 'wired' (it usually is but if not tap to connect)
5, go to WiFi settings on iPad #2 and check connection to "My DL1608" then start MF, check in settings "wireless DL1608" is connected.
6, wait at least 1 min then start switching on FOH and monitors (I use all active/powered cabs).
Powering off:-
1, mute all channels/outputs (usually, not every time) and save show on both iPads.
2, switch off
all powered cabs
3, wait at least 1 min then switch off DL1608.
I usually set the desk up first then go through the power on sequence while wiring the FOH and monitors (so I'm not standing around waiting for the router/DL/iPads to boot), prove the system with some music from the iPad then rig mics and DIs as required. I also rig power cables first, signal cables next and mic/DI cables last, de-rigging in the reverse order (and I coil my mic/signal cables 'under & over' plug the XLRs together and secure with a velcro tie..... a well coiled cable is a thing of beauty
)
