So what's Balanced Power?
In the USA, electric power is delivered to homes in a "single-ended" fashion with two wires.  One wire, called the neutral, is always held at 0 volts.  There is no voltage on it.  The other wire, called the hot, carries all of the 120 volts AC.  Balanced power converts the single-ended power to a balanced power system with both wires now carrying 60 volts AC, each out of phase with each other.  The total voltage between them is then 120V.  The ground wire is held at 0 volts.


How does it remove power line noise?
Transformers only respond to voltage differences between their leads.  Power lines often have a type of noise called common mode noise which is present on both the neutral and hot wire.  The Balanced Power Supply contains a massive toroid transformer that reject much of this noise.

But what about noise on just the hot wire?
The output of the Balanced Power Supply contains heavy filtering to eliminate much of this noise.  Often times, audio equipment itself generates noise that gets fed back into the power line.  The noise is then free to invade other equipment.  Power amps with laminated power transformers can be the worst offenders.  The heavy filtering on the output can help to eliminate much of this noise.

What is a ground loop?
A ground loop occurs when different equipment grounds are at different voltages, causing noisy ground currents to flow between them.  The Balanced  Power Supply creates a new ground called a derived ground, that decouples equipment connected to it from these circulating ground currents in the rest of the house wiring.  It also provides one common ground reference for all the equipment connected to it.


How does it reduce radiated fields?
Because the power is delivered by two out of phase signals, the electric fields produced by each should largely cancel.  This reduces noise caused by radiated fields.  This is same principal used with twisted pair cable but in reverse.  Instead of rejecting noise, power carrying cables don't radiate noise in the first place.

How does it reduce interference between equipment?
Most modern electronic equipment uses switching regulators in their power supplies.  These devices can produce RF noise that can couple through the power cord to other equipment.  The balanced power supply provides a very low impedance to the connected equipment which shorts out this high frequency noise.  Some users have reported improvements in large screen video performance.


How does the unit provide a soft start?
By using a simple and reliable thermal device, inrush currents on start up are greatly reduced.  As the thermal device heats up in a few seconds, normal power currents are restored.  Very simple.  Very effective.

How many outlets does it have?
To accommodate varying needs of users, the unit has one heavy duty outlet on the rear and is shipped with a six outlet power strip.  This lowers cost, makes the product easier to put together and gives the user complete flexibility for power cord connections. 


The enclosure  is a match to our very popular Grounded Grid Preamp.  Same size, materials, and finish.  This is a low cost product that has the looks and performance of equipment that sells for four times the price.
