WHEATSTONE AUDIO CONSOLES May 1998
AT T E N T I O N !
If your Wheatstone audio console has been ordered
and shipped with a failsafe power supply system, it
uses TWO separate rackmount power supplies. Though
either is capable of running the console on its own, in
failsafe operation both units run in tandem: if one fails,
the other takes over, assuring uninterrupted console
operation.
Dual failsafe supplies have their output trimmed to
entirely different settings than stand-alone single units,
and are MEANT to be run in tandem.
If they are not, and
you attempt to “save” one supply by powering it down and
holding it in reserve until you run into an actual failure
condition, you could shorten the life expectancy of the
working unit.
!
In order for the failsafe system to perform as
designed, always have BOTH rackmount
supplies powered up and connected to the
console.
