The PS-PRO is a power sequencer, meaning it is ca-
pable of powering a rack full of equipment in three
steps separated by timed delays. It is useful whenev-
er various kinds of equipment must be powered up
or down in groups, rather than all simultaneously.
In audio systems, sequenced powering is often
necessary to allow turn-on transients from low level
amplifiers and processors to settle down before any
power amps are turned on, because simultaneous
powering would result in a loud, annoying, and
potentially destructive “pop” reaching the speakers.
And in any large system whose components present
an inductive load to the AC line (including electric
motors, power supplies, and power amplifiers of all
kinds), sequenced powering can avoid excessive
inrush currents that can cause circuit breakers to
trip even though the steady-state currents are not
excessive. Power sequencing is particularly suited
to applications where large installations must be
switched by inexperienced personnel.
The PS-PRO is controlled by a front panel key-op-
erated switch to provide security from non-autho-
rized users tampering with the system. The switch
has three positions: OFF, ON, and REM, allowing
for local or remote control. With remote control,
one or more PS-PRO’s may be installed in remote
locations with on/off control and LED monitoring
via low-voltage control wires.
Besides its power sequencing capabilities, the PS-
PRO contains many other conditioning and protec-
tion features. Both aspects of its functioning will be
discussed in the next sections.
