The CH Precision C1.2 Digital to Analog Controller is a cornerstone piece for any digital arsenal and can be further configured for higher performance and functionality.

Digital conversion lies at the heart of the C1.2 digital-to-analog controller. Perfectly preserving time and amplitude information is critical to reproducing musical signals stored in digital formats. A MEMS-based, shunt-regulated, and thermally compensated clock addresses both noise and jitter.

The proprietary CH-PEtER algorithms benefited from a fourfold increase in processing power. They now support 32-bit fixed-point processing and have increased input compatibility to include all high-resolution digital formats, whether from optical or file replay sources.

The CH-Link HD interconnection allows the transfer of native DSD and MQA data in the digital domain, from the D1.5 transport to the C1.2. The AES/EBU and S/PDIF inputs accept PCM at up to 192kHz/24bit resolution, while the HD streaming input will accept PCM data at up to 768kHz/32 bit resolution and DSD512(8x). Local regulation of the DSP and FPGA further reduce the system noise floor.

The DAC employs four converter chips per channel in a fully differential, dual-mono topology. The vital analog output stage is discrete, fully differential, Class-A, and DC-coupled. The modular input architecture ensures that the C1.2 remains future-proof and can adapt to changing digital standards or system demands.

The C1.2 can be expanded in the field into a 4-box digital solution, making it true monaural, each with its X1 power supply.
