Hear your DAC as it was meant to be heard. OPTO•DX™ is the superior remedy for RF noise in a single or dual-coax SPDIF interface. It works by modulating the SPDIF signal to optical and back to SPDIF over an optical bridge for total optical isolation with no latency. Further, OPTO•DX has independent 12VDC inputs for each side of the optical bridge to provide complete power isolation using separate circuits or battery packs.

While cleaner sources, ferrite-laden coax cables and other tweaks may attenuate RF noise to the level of your systems’ subjective noise floor, OPTO•DX’s optical galvanic isolation provides an objectively superior solution for those with the most revealing systems and highest appreciation for musical transparency. With OPTO•DX you will hear a more perfect D/A conversion: a less bright, smoother presentation with more subtle details revealed - and you can listen louder and for longer without listening fatigue.

OPTO•DX is configured as a transmitter and receiver linked with industrial-grade optical cables.  Also included are two pairs of thin and flexible coax patch cables to ease connection without unwieldy cable management. For power, AudioWise options a very good 12VDC SMPS supply but strongly recommends using a battery power pack like the PowerAdd Pilot Pro 2 or an low-noise supply like the UpTone Audio UltraCap LPS-1.2.
