1 Technical Highlights
CH products are proudly designed and manufactured in Switzerland by CH Precision Sàrl. Our engineers have put all their know-
how into bringing you the C1, a top performances future-proof digital to analog (D/A) controller, based on slot-in boards and USB
flash-drive firmware update. In its base version the C1 is a four inputs D/A converter, with integrated preamplifier functions such
as source selection and volume control. Default configured C1 have one DIGITAL_IN board and a CONTROL board. Audio inputs on
each DIGITAL_IN board include three standard digital audio connectors (RCA coaxial S/PDIF, TOSLINK optical S/PDIF and XLR AES-
EBU) supporting S/PDIF encoded PCM up to 24bits/192kHz, as well as proprietary high definition CH Link interface, supporting
both I
2
S PCM (up to 32 bits/768kHz) and native DSD audio signal connection.
Optional boards allow to extend the functionality of the base version of the C1 D/A controller. By adding extra DIGITAL_IN boards
(a total of up to three input boards can be plugged in the unit), the C1 can be connected to even more standard digital sources.
Addition of optional USB_IN board and/or optional NETWORK Ethernet streaming board (replaces standard CONTROL board)
unleashes the full capabilities of the C1 as the ultimate high-resolution computer audio file player. On the other hand, ANALOG_IN
optional board will turn your C1 into a top quality preamplifier while offering single-ended RCA and balanced XLR analog inputs.
Finally, the SYNC_IO optional board provides advanced clock synchronization capabilities for use with external clock generators or
to enslave the D1 SACD/CD drive to the C1's Masterclock for zero-jitter connection.
