The JCAT USB Isolator blocks all noise coming from a PC and re-generates clean USB signal from scratch. It is capable of transmitting USB Hi-Speed (480 MBit/s) while providing full galvanic isolation up to 2.5 kV of both data and power lines – ideal solution for any sensitive applications requiring high-speed data transfer such as high end computer audio.

Audiophile USB audio high speed galvanic isolation

World's first USB 2.0 galvanic isolation

Recreating and reclocking of USB signal is done by a fast FPGA-based circuit inside the JCAT USB Isolator’s aluminum housing. The enclosure acts as a shield against harmful electromagnetic interference (EMI/RFI) to further minimize noise. Breaking all the noise coming from a PC results in vast sound quality improvements.

Exceptional USB Audio quality with any device

JCAT USB Isolator is a perfect solution for computer audiophiles seeking maximum sound quality from their USB DACs and USB-DDCs regardless of whether used with a PC, laptop or Mac.
JCAT USB Isolator can work alone or in chain with our JCAT USB Card. We recommend JCAT USB Cables for best performance.
