sCLK-EX New Clock Board

sCLK-EX New Clock Board

Regular price $1,000.00 AUD

The new clock board is available to output 4 points, so it could be connected to M/B, Lan port, tX-USBexp or tX-USBhubIN and another point at the same time by “a single sCLK-EX board”. The performance and features have been very much upgraded and improved than the current clock, so it will be a worthy challenge and news for all computer audiophile users.

Also the sCLK-EX can be synchronized to the external clock, so it can be synchronized with Rubidium or Reference clock.
