JCAT USB Card XE EVO

The Emerald OCXO provides exceptional timing stability of ±5 PPB, which significantly reduces jitter. This precision ensures that your digital audio data is transmitted with higher accuracy, resulting in a cleaner and more detailed soundstage.

While the card draws power from the PCIe slot, it is designed to be used with an external 5V/1.5A linear power supply for optimal performance. Using an external PSU bypasses the noisy power environment of a standard PC, which is essential for achieving the lowest possible noise floor.

The card features an SMA connector that allows you to bypass the internal clock and connect a high-end external Master Clock. You can easily toggle between the internal and external clock sources using the onboard switch, giving you flexibility to experiment with different timing references.

The XE EVO features a refined design that cuts noise levels nearly in half compared to its predecessor. It also incorporates updated linear voltage regulators and optimized firmware that disables power management, ensuring the card is dedicated entirely to audio performance.

No, the card is designed to be plug-and-play with standard USB audio drivers. Because it uses an optimized PCIe interface, it is recognized by your operating system as a standard USB controller, making it compatible with virtually any DAC that supports USB input.

The advanced EMI filter is designed specifically to clean up the signal path for audio devices without impeding data transfer speeds or compatibility. It effectively blocks high-frequency interference from the computer's motherboard, ensuring your DAC receives a pristine signal.
