C10 Digital to Analog Converter

C10 Digital to Analog Converter

Same old story – a whole new performance…the C10 Digital to Analog Converter

In many ways, the guiding principles that underpin the C10’s design are firmly rooted in the existing 1 Series. But the revised topology, the novel DSQ™ Phase Array DAC architecture, and the incredibly sophisticated grounding and power supply arrangements deliver a whole new level of upgradable, configurable, musical performance. The 16 software-driven R2R DACs at the heart of the C10 mean that it is both updatable and future-proof: as future-proof as the C1.2 – still at the top of its game after 15 years. The C10 establishes a completely new standard for musical performance, practicality, and versatility. It promises its owners a relationship that’s as long as it is musically rewarding.

The C10 relies on the proven performance of the PCM 1704 R2R DAC chip, driven by our sophisticated DSP-based, short-tailed PEtER over-sampling algorithm. The DSP operates at a 32-bit fixed point before conversion to 24-bit at the output, the native resolution of the PCM 1704. The C10 uses 16 DACs in a dual differential, sequential DSQ™ Phase Array topology.

The C10 power supply provides four independent, highly regulated multiple DC feeds to galvanically isolated circuit blocks within the chassis: the digital processing circuitry, the clock, and the left and right DACs. The audio chassis has adopted a mirror imaged layout, the modular input cards located centrally with the DACs disposed on either side and benefiting from symmetrical clock feeds.

This pure DAC is dedicated to delivering the best possible performance from digital storage media. Best performance demands pairing it with a top-flight line-stage pre-amplifier, like the L10. To optimize system matching, it offers user-selectable output levels (1, 2.5, or 5V) and switchable local/global feedback. Inputs are still modular and configurable. The C10 is fitted with CH-Digital-IN HD and Ethernet Control cards as standard, providing connection to CH-LINK HD, AES/EBU (XLR), S/PDIF (RCA), and TosLink optical inputs and also allowing network control via the CH-Control App.

The Ethernet Control card can be upgraded to the Ethernet-In HD card, creating a high-quality streaming interface (compatible with all major streaming services). Three additional slots allow users to fit an extra digital input card, a USB input, and the Clock Sync card for connection to an external 10MHz master clock, such as the CH T10 Time reference.

The C10 Mono

To move from the C10 to the C10 Mono, you simply add an extra power supply. The separation of the circuit blocks within the C10 audio chassis, combined with the four discrete DC feeds from the power supply means that we can surpass the benefits of the six-box topology by adding a single extra power supply chassis, splitting the DC feeds between them. Same significant step up in performance – half the boxes to accommodate.
