Humbuster III 

Getting Started 1 

Once your new HB-III is unpacked, you’ll need to find a convenient place to set it.

There are several ways to mount the HB-III, on a rack shelf, on the floor behind an equipment or rack 
shelf, mounted to a wall or ceiling using the optional wall mount kit.

The HB-III can generate some heat.  This is normal if the HB-III is required to power a large amplifier 
or projector.  Caution should be taken to keep the HB-III in a well ventilated area if it is going to be 
used on a large current draw piece of equipment such as a power amplifier.

If the HB-III is to be placed on the floor or carpet, make sure the unit is not going to come in contact 

with water or cleaning solvents.  

The HB-III can benefit from aftermarket isolation devices such as cones, spikes and Sorbothane 

pads.

Once you have chosen the location for the HB-III you can use the supplied AC power cord to 
connect it to the AC wall receptacle or you can use an aftermarket power cord and receptacle.

We strongly recommend the use of a PS Audio xStream AC power cable and a PS Power Port AC 
receptacle to feed the HB-III power.  While the supplied power cable is adequate for the task it is not 
going to provide the best performance.  Choosing any xStream power cable will make a significant 
performance improvement over the stock PS supplied power cable.

We recommend one HB-III for each piece of equipment that is producing internal mechanical hum 
if possible.  While it is perfectly acceptable to run multiple pieces of source equipment from a single 
HB-III it is recommended that larger power draw equipment, such as a power amplifier, be limited to 
its own HB-III for power.

If you are using additional power conditioning equipment, such as a PS Audio Duet, it is 
recommended that the HB-III be placed before the Duet/Quintet.

If the additional power conditioning products used are a Power Plant, balanced transformer, or 
multiple outlet surge protectors, it is recommended the HB-III 1 be placed after these devices.

The exception to this suggestion is if you are trying to lower or eliminate the internal transformer 

noise of the power conditioning device itself.  In this case, you will need a Humbuster before the 
power conditioner to reduce or eliminate the noise internal to the conditioner.
