JK Audio Pureformer - Manual (Page 2)

Pureformer is a simple solution to many noise and hum
problems which occur when two audio products are
connected together. Pureformer can be used wherever
line level audio signals are connected between two or
more pieces of equipment such as: computer sound
cards, mixers, pre-amplifiers, tape decks, crosspoint
switches, etc.
Pureformer works in two ways. First, it isolates the elec-
trical grounds of both pieces of equipment. This is es-
pecially important in the case of computer audio cards
connected to high quality / low noise audio equipment.
The computer electrical ground is often filled with noise
from disc drive activity and data transmission.
Many audio cards use the same electrical ground for
the computer and the audio signal. When the computer
audio card is connected to your studio equipment, the
electrical noise from the computer can get into the rest
of your audio system. Pureformer completely isolates
the electrical ground of the two systems and only al-
lows audio signals to pass through. Pureformer cannot
remove noise once it has been mixed with the audio
signal, so it is important to find and treat the source of
each problem.
