Introducing Pureformer

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 filled 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 find and treat the source of each problem

FAQs

Will the Pureformer eliminate the 60 cycle AC hum I have on my recordings?
No. The Pureformer cannot remove noise after it has already entered the audio signal. It will only prevent noise from entering before the recording takes place.
