JCAT has released its brand new Master OCXO Clock, which can be the icing on the cake of your (digital) sound system.
The new JCAT Master OCXO Clock is an extremely accurate and entirely in-house designed oven-controlled crystal oscillator. You connect it to one of the USB or NET XE cards, which the manufacturer also has in its product range. Nice detail is, that if you have a USB Card XE in use, it will be provided for free and for nothing (worldwide) with the necessary modification to connect the Master OCXO Clock. After purchasing the OCXO, you send the USB card to the factory in Poland, where everything is taken care of. Technically, it means that an adapter is installed that allows interfacing with the Master OCXO Clock. Pickup and shipping is done via UPS, only the patience you have to take care of yourself. Very much of that is not necessary: JCAT promises that the complete process takes no more than 7 days.
Loose or as a set
The JCAT Master OCXO Clock comes with an appropriate HF clock cable, which you simply plug into the factory-adapted USB card. If you don’t yet have a USB XE card, it is also possible to buy a set consisting both such a card and the Master OCXO Clock.
The price of the JCAT Master OCXO Clock is €1200 (and that includes adaptation of the mentioned USB card).
