Re: Hey digital console users don't forget your UPS


I thought that cheap UPS's were predominantly square-wave in output?  I can hear nasty-buzz noises coming from power supplies even on computer gear that make me feel like damage is being done. (It's like running your gear off a lighting-dimmer!)


If you don't want to get a costly full sine-wave output unit then I'm thinking no UPS is better than a cheap one.

(And even some sine-wave units don't look all that great on a 'scope when loaded)


Detailed spec-sheets and specifics on the cheap-ones are very "monster-cable-esque" as mentioned previously.


The answer is simple:  Do not use a <$200 UPS on your $25,000 digital console! (or a $45 one on your $8000 Stage-box)


Also, protection of gear aside, how about dropping a show because the UPS fails!  Not unreasonable considering that cheap ones are intended for stationary under-desk home use.


I can't understand why console manufacturers don't offer optional external UPS type technology specifically matched for their boards?  They all offer standby external PSU's with switch-over technology or shared-redundant, why not an external UPS unit that deals with the DC rails directly?  It could even integrate on-screen so you can get warnings and battery status display.  (Seems like something they could make good sales on)
