About JK Audio Pureformer

Bring your audio experience to a new level of clarity with the JK Audio Pureformer Stereo Isolation Transformer. Engineered to provide superior hum and noise reduction, this high-quality device is an essential tool for sound cards and audio equipment. It effectively removes ground loops and DC paths that can cause signal breakup and unwanted hum, ensuring your audio output remains clean and clear.

The Pureformer's primary function is to isolate the electrical grounds of two pieces of audio equipment, a critical feature when connecting computer audio cards to high-quality, low-noise audio equipment. Computers often have electrical grounds filled with noise from disk drive activity and data transmission. Many audio cards share the same electrical ground for the computer and the audio signal, which can lead to electrical noise leakage into your audio system when connected to your studio equipment.

The innovative design of the Pureformer completely isolates the electrical ground of the two systems, allowing only audio signals to pass through. This user-friendly and effective device operates with a frequency response of 20Hz to 20kHz and an impedance of 600ohms, making it compatible with a wide range of amplifiers and other audio equipment.

Please note that the Pureformer cannot remove noise once it has been mixed with the audio signal. Therefore, it's essential to identify and treat the source of each problem for optimal performance. With the JK Audio Pureformer Stereo Isolation Transformer, you can enjoy a noise-free, high-quality audio experience.
