this post is about hardware safety in event situations
given the following desktop setup:
- multiple gpus feeding led panels (2x gtx780, via active edid boxes)
- videoin (intensity usb3)
- audioin from sounddesk (steinberg u55, usb)
- midi controller (usb)
- powersource is(was) 860w
computer froze, then failure of multiple hardware parts:
- one edid box died on the spot (service replaced its ps)
- external soundcard also died on the spot (service replaced it)
- after a few days, i had to change the powersource due to inconsistent behavior
- now am looking at inconsistent usb3 behavior, from the mobo side … and probably will have to change it also
this incident made me think about what is what in terms of electricity
cause
- is it plausible that this can happen if the audiosignal comes from a different phase ?
prevention
- would a surge-protection have prevented this ?
- would a DI unit on the audioin have prevented this ? until now i was using one only if i was av-streaming…
- is it important to protect all in-out points ? (power, a/v in/out)
any thoughts or references on this topic are welcome
/thanks
