[Pre-Sale]Douk Audio U7 S/PDIF Reclocker with SRC4392 ASRC and Femto Clock 192kHz

Features

Upgrade the Digital Link: Keep your current source and add dedicated S/PDIF reclocking before the DAC. U7 attenuates upstream clock jitter and rebuilds output timing from a precise local reference, helping bring out more focused imaging, clearer separation and a more open, natural presentation.

Especially useful with computers, TVs and general-purpose digital sources, or where timing or lock stability matters. SRC4392 ASRC + Femto Clock: At the core, U7 pairs TI Burr-Brown’s SRC4392 ASRC with femtosecond clocking in a high-spec reclocking architecture built for exacting digital timing. Oscillator jitter is below 39 fs, with instrument-measured THD+N at 0.000006% and SINAD at 147.2 dB—strong measured evidence of U7’s signal purity. Choose 96 or 192kHz Output: U7 accepts PCM up to 24-bit/192kHz and lets you choose the fixed output that suits your DAC instead of being limited to one setting. Select 192kHz for high-sample-rate content to avoid unnecessary down-conversion, or 96kHz for DACs without 192kHz support, balancing high-rate playback with broader compatibility. Simplify Your Digital Connections: Keep optical and coaxial sources connected and switch between them without reconnecting cables. Whichever source you select, U7 converts and routes it to coaxial, optical and BNC S/PDIF outputs, all active simultaneously—bridging interface mismatches and feeding multiple downstream devices from one source. Engineered Down to the Details: The compact aluminum chassis fits easily into desktop, shelf or full-size HiFi setups. Standard 5V USB-C keeps power simple and leaves an easy path to a linear supply.

Pure-copper, gold-plated coaxial connectors resist oxidation, while built-in overvoltage protection supports reliable long-term use.
