Owner’s Reference
UPC-HB Power Center
The UPC-HB is best left powered on at all times. The current draw is negligible and keeping it powered
on will make sure the internal AC capacitors stay working properly.
There is no harm in leaving the unit on at all times as the lifespan of the UPC-HB will be unaffected by
leaving it on.
There are no user replaceable internal fuses inside the
UPC-HB. There is a user replaceable surge board. The
components inside the UPC-HB have lethal voltages when
powered and even when un-powered. Capacitors inside
the UPC-HB can retain an electrical charge after the unit has
been powered down. Do not attempt to get inside the unit
for any reason unless instructed to do so by your dealer or
an authorized service representative. Should the UPC-HB
cease to function, contact your dealer or PS Audio’s service
center for help.
The AC receptacle is a critical link in the electrical chain. If
you are using a standard AC wall receptacle to power your
equipment, we would recommend the use of a Power Port
AC receptacle, a hospital grade AC receptacle or at the
minimum a high quality spec grade receptacle. The connection between the wall AC receptacle and
your equipment can be a critical link in the success of your equipment’s performance.
Placement of the UPC-HB is not critical.
Placement with respect to other equipment can be important. In general, place the UPC 200 between
the unit you are powering and the AC source. If you are using a power conditioner, balanced isolation
transformer or Power Plant, place the UPC-HB between those devices and the unit you will be
powering.
Isolation through the use of spikes, cones or Sorbothane feet is recommended for the UPC-HB if
space and budget allows. Isolation of any piece of high-end stereo and theater equipment is always
recommended wherever practical.
The UPC-HB will not eliminate hum in the loudspeaker. Using the Filter and Humbuster output should
reduce mechanical humming noises inside the unit. So, for instance, if you have a power amplifi er
that has a humming/buzzing noise coming from inside its chassis, that would be a good candidate for
removing hum.
The UPC-HB is specifi c to your country’s voltage. Do not use the UPC-HB on a voltage higher than
it is rated for. For instance, do not take a 120 volt rated UPC 200 and attempt to use it in a 220 volt
country. Failure to observe this cautionary note will void your warranty. If you need to operate the
UPC-HB at a voltage other than the voltage it was designed for, contact your dealer, distributor or the
