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 S/PDIF (DX) interface. It works by modulating the DX signal to optical and back to DX over an optical bridge for total optical galvanic isolation. Further, OPTO•DX has independent DC inputs for each side of the optical bridge to provide complete power isolation and reduced noise using battery packs or low noise supplies.
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 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 fatigue. Less measured RF noise at the DAC is a direct corollary for better sound.
OPTO•DX is configured as a transmitter and receiver linked with industrial-grade optical cable. Optional thin coax patch cables ease connection to components. For power, AudioWise strongly recommends use of battery packs to stop RF from bypassing the optical bridge via the AC mains. Please consider the PowerAdd PilotPro5 (or similar) with low impedance DC power cables at the receiver end. Download the PDF here for recommended power isolation configurations.
