High Quality, Low Distortion. The Pureformer provides
hum and noise reduction for sound cards and audio
equipment, and removes ground loops and DC paths that
can cause hum and signal breakup.
Isolate the Problem. The Pureformer isolates the
electrical grounds of two pieces of audio equipment.
This is especially important in the case of computer
audio cards connected to high quality/low noise audio
equipment. The computer electrical ground is often lled
with noise from disk 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 leak into the rest
of your audio system. The Pureformer completely isolates
the electrical ground of the two systems and only allows
audio signals to pass through. Pureformer cannot remove
noise once it has been mixed with the audio signal,
so it is important to nd and treat the source of each
problem.
