CH Precision C10 DAC

🔧 CH Precision C10 DAC – Technical Highlights & Innovations

🧠 Digital Signal Processing (DSP)

  • Four independent 2.4 GFLOPS DSP engines for real-time digital processing without latency or compromise.

  • Proprietary CH-PEtER 32-bit fixed-point DSP performs synchronous oversampling and data optimization for R2R conversion.

  • Direct DSD-to-PCM conversion at 705.6kHz ensures native handling of SACD and DSD content.

  • Full MQA decoding (unfold + render) up to 24-bit/768kHz, with true analog output stage resolution.

🎚️ Digital-to-Analog Conversion

  • Eight PCM1704 R-2R DAC chips per channel in DSQ™ Phase Array topology, operating at 64x sample frequency.

  • Fully complementary, dual mono symmetrical design for optimal channel isolation and balanced performance.

  • Discrete, ground-isolated linear power supplies feed each channel, minimizing crosstalk and digital contamination.

🕒 Clocking and Timing

  • Ultra-low-jitter MEMS-based, thermally stabilized Master Clock with dedicated shunt-regulated power supply.

  • CH Link interface ensures ultra-precise, LVDS-based synchronization between the Conductor and Master DAC chassis.

🔊 Audio Path and Analog Output

  • Pure Class A, DC-coupled, fully symmetrical analog output stage.

  • High slew-rate, low-noise discrete circuit topology with wide bandwidth.

  • Selectable Local or Global feedback; user-switchable mono output (L+R) and absolute phase reversal.

  • Third-order Sallen-Key Bessel filter for perfect group delay and time coherence.

  • Analog outputs:

    • 1x Balanced XLR

    • 1x Single-ended RCA

    • 1x BNC

🖥️ User Interface & Control

  • 5-button front panel interface with full functionality.

  • High-resolution AMOLED 800x480 display.

  • Remote control via infrared or Ethernet (CH Control app).

  • Integration-ready with home automation systems via network API.

⚡ Power Supply Architecture

  • External PSU with 3 dedicated transformers for audio, digital, and clock domains.

  • >1.5 Farad total capacitance ensures incredible energy reserves and transient response.

  • Multiple cascaded discrete linear regulators with shunt topology for critical analog and clock stages.

  • Fully independent left, right, digital, and clock ground planes for maximum signal purity and isolation.
