Why do I need it? |

All our local main power
distribution is unbalanced. So its vulnerable to interference in the
same way as unbalanced audio lines, and there is plenty of interference
to pick up: from motors, fluorescent lights, switch-mode power supplies
and dozens of other reactive loads. All of these feed spurious harmonics
and out of phase components back into the mains. The more devices on the
circuit, the more these reactive currents can go into the earthing
system. The resulting noise in your grounding system is a major
contributor to a studio’s “noise floor”- that stubborn residual noise
and hum you just can’t get rid of, Star earthing scheme, power
conditioning and cable routing cant solve it. The Balance Studio Power
Supply eliminates these reactive power components in exactly the same
way as balanced audio circuits eliminate external noise. The reactive
currents in a balanced power circuit sum to zero at the power supply’s
earth.
You will immediately notice
everything is quieter. There is an audible improvement in frequency
response and stereo imaging. Even digital transfers are cleaner.
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 if 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.
