Quick Start Guide
Turn off the unit you are going to power with the HB-III. We recommend turning all equipment in the
system off or to standby mode when powering down the unit you wish to power with the HB-III.
Remove the power cord that was powering your AV unit from its power source. The power source
could be a wall AC receptacle, the output of a power conditioner, surge and spike protector or a
Power Plant AC regenerator.
Plug the HB-III into the power source using the AC power cable you selected. It is advisable to use
as short a power cable as possible to the HB-III. We do not recommend plugging the HB-III into an
extension strip or plug extender unless it is of the highest quality and heavy duty design, such as the
PS Audio Juice Bar or device with similar properties.
Once the HB-III has been connected to the power source, make sure that power source is energized
and providing AC power to the HB-III. If you are using a Power Plant Premier, only use the HB-III on
the AC input to the Premier; never use the HB-III on the output of the Power Plant Premier.
If you are using an AC wall receptacle to power the HB-III, make sure the AC receptacle is not a
switched outlet. Switched outlets are those outlets that can be turned on/off with the wall switch.
It is advisable to leave the HB-III powered at all times.
Once the HB-III has been powered, plug your AV equipment into the AC receptacle of the HB-III. Make
sure to use a high quality aftermarket AC power cable to power your equipment from the HB-III. It is
important to note that the AC power cable is a critical link in the chain and great care should be
taken to ensure only the best non-restrictive AC power cable is used to power both the HB-III and
your AV equipment.
Turn your equipment back on. Make sure everything is powered up properly with the HB-III between
the AC receptacle and your AV equipment.
You should notice decreased mechanical internal hum from your powered AV equipment.
We recommend on any use of a power amplifier that only one HB-III be used. Small to medium
power amplifiers can share on HB-III, but for larger power amplifiers it is strongly recommended you
use separate HB-III's.
HB-III can generate heat. If you are powering a large wattage power amplifier or projector, the HB-
III can produce heat and the chassis of the HB-III can get quite warm. This is normal and to be
expected under these conditions.
Very large amplifiers such as tube amps and class A amps can draw a lot of power and the
Humbuster may get hot to the touch. This is normal.
