The End of Digital Silence. The Beginning of Pure Sound.
Break the noise chain. Precision Audio presents ClearLink, the definitive galvanic isolated USB cable for critical listening.
Full Galvanic Isolation
Breaks ground loops between streamer and DAC.
Blocks digital electrical noise from traveling between equipment.
Result: Dead-black music background.
External DC 5V Input (Critical for SSD users)
Provides dedicated clean power for high-current devices (SSD, external hard disk).
Prevents the streamer’s USB port from being overloaded.
No noise injection – clean external supply powers the device, not the audio path.
Sonic Results
Dark background – Silence between notes.
Enhanced clarity – Instruments and voices gain focus.
Micro-details revealed – Hear room ambiance, bow strokes, and subtle decays previously masked by noise.
Pure Silver Solid Core (Cryo-Ed)
Superior conductivity over copper.
Cryogenic treatment reduces grain boundaries.
Result: Enhanced micro-detail, air, and extension.
Gold-Plated USB Connectors
Ensures low-contact resistance.
Resists oxidation for long-term reliability.
USB 2.0 HiFi-Optimized
480 Mbps — supports PCM 768kHz, DSD512, all hi-res formats.
Plug-and-play, no drivers required.
Where to Use ClearLink
| Use Case | Connection | Why It Helps |
|---|---|---|
| Streamer → DAC | USB A to USB B | Removes USB ground noise from streamer |
| External SSD → Streamer | USB A to USB A or B | External DC input provides stable 5V for the drive; isolation blocks drive PSU noise |

| Function with External DC | Powers high-current devices (SSD, HDD) without taxing streamer’s USB port |
| Backward Compatibility | Works with USB 1.1 and USB 3.0 hosts (at USB 2.0 speed) |
| Connectors | Host: USB A Device: USB B |
| Length | 1.0m |
How to Use the External DC 5V Input
Without external DC: Cable works as a standard galvanic isolator (may not provide enough current for SSDs).
With external DC (recommended for storage drives): Connect a clean 5V power supply to the cable’s DC input jack. The cable will draw power from this external source to run the downstream device (SSD/HDD/DAC), leaving the streamer’s USB power untouched.
Tip: For best results with SSD playback, use a linear power supply or battery on the DC input.
Sound Description (For Audiophiles)
Blacker background – No electrical haze.
Tighter bass – Ground loops often muddy low frequencies; removing them cleans up bass articulation.
More natural treble – Digital harshness disappears.
Better instrument separation – Each element occupies its own space.
