Features
High-Precision Master Clock Generator.
JCAT’s first-ever in-house developed high-precision ultra-low noise OCXO (Oven-Controlled Crystal Oscillator) Master Clock Generator replaces onboard clock oscillator on the USB Card XE. The exceptional characteristics of the Master OCXO Clock Module deliver a realistic and refined sound quality beyond your wildest dreams.
No-Compromise Expert Design.
The Master OCXO Clock board and the included RF clock cable were designed in collaboration with a specialist in radiophysics who provided invaluable insights ensuring that every technical aspect was carefully considered. By focusing on the most subtle nuances, JCAT has attained an unparalleled level of musical playback quality within the realm of digital audio.
Superior OPTIMO Power.
The power supply section on the Master OCXO Clock module derives its excellence from the distinguished OPTIMO series truly-linear power supplies. It features two separate power phases for the Oven-Controlled Crystal Oscillator and for the clock output buffer guaranteeing peak performance while minimizing unwanted interference.
Luxurious Audio Commponents.
The Master OCXO board is meticulously gold-plated, fitted with premium audio components ensuring top-quality connections and reliability for years.
The ultimate and the best upgrade for your USB Card
While the OCXO found on USB & NET XE cards is already of exceptional quality, opting to upgrade to the Master OCXO instantaneously elevate your digital frontend to a level akin to possessing a higher-class DAC. Invest in the Master OCXO Upgrade and experience the difference in sound quality that will take your audiophile experience to an entirely new level. The price includes free worldwide door-to-door upgrade service; the customer will receive a pre-paid UPS Express return label for his USB Card XE, the card will be upgraded at our factory in Poland and the customer will receive upgraded USB Card XE with the Master OCXO as pictured below.
