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.
