CH Precision C1.2 DAC Controller
Naturally, the digital conversion is the core of the C1.2. The perfect preservation of time and amplitude information is crucial for reproducing music signals stored in digital formats and the C1.2 is a further development of the now famous C1. Digital music reproduction is lifted to a completely new level.
Both Ruis and Jitter are central to the design of every high -quality DAC. CH Precison has developed a completely new Mems-based, shunt-controlled and thermally compensated clock for the C1.2, which improves the clock accuracy considerably (and also highly developed clock synchronization and external reference clock options are offered). A four-fold increase in the processing power has enabled them to further refine the patented CH-Peter algorithms, introduce 32-bit fixed point processing and to increase the input compatibility to edit all digital sizes with high resolution, regardless of the digital source. The own CH-Link HD interconnection makes the transfer of native DSD and MQA data in the digital domain possible, from the D1.5 transport to the C1.2. The AES/EBU and S/PDIF inputs accept PCM with a resolution up to 192 kHz/24 bit, while the HD streaming input PCM data accepts with a resolution up to 768 kHz/32 bit and DSD512 (8x)! Local regulation of the DSP and FGPA further reduces the system noise floor. The DAC itself uses no less than four converter chips per channel, in a fully differential, dual-mono topology. The essential analog output style is discreet, fully differentially, class-A and DC. The modular input architecture ensures that the C1.2 remains future -proof and can adapt to changing digital standards or system requirements.
After the digital decoding core of the C1.2 was created, the next step was to construct the system architecture around it. In addition to the established digital input standards (AES/EBU, S/PDIF and TESLINK), users can configure the C1.2 specifically for their system and play requirements by offering individual Ethernet streaming and USB invo card cards. In addition to the multiple digital input and clock synchronization options, there is also a bypassable hybrid volume control, which works in both the analogue and the digital domain, and an A-to-D-D-Facility, so that the C1.2 can be at the center of each system, regardless of the source components used.
