JCAT USB Isolator

Clean up your USB signal and get better sound

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. 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. 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.
