The DENAFRIPS Terra MCLK is a flagship-grade audiophile master clock generator designed to elevate digital playback systems to reference levels. Operating on the principle that clock accuracy, thermal stability, and phase noise reduction form the foundation of digital fidelity, the Terra serves as a central timing reference for high-end DDCs, DACs, and digital transports.
The unit houses dual Oven Controlled Crystal Oscillators (OCXOs) running at base frequencies of 45.1548 MHz and 49.152 MHz. These precision oscillators are powered by a multi-stage linear power supply featuring an oversized O-Core transformer optimized for ultra-low noise, high slew rate, and thermal stability. Equipped with four 75-ohm BNC output ports, the front panel allows flexible configuration of both fixed and adjustable master clock frequencies.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- High-Precision Dual OCXOs: Enclosed Oven Controlled Crystal Oscillators running at 45.1548 MHz and 49.152 MHz to eliminate jitter and thermal drift.
- Oversized O-Core Linear Power Supply: Multi-stage linear power supply providing high current, high slew rate, and low-noise DC to prevent crosstalk.
- Four Configurable BNC Outputs: Four independent 75-ohm BNC ports (MCLK1–4) configurable via the front panel to interface with various digital audio components.
- Fixed & Adjustable Frequency Modes: Offers fixed master clock outputs alongside scaled multiplier frequencies (44.1/48 kHz, 11.2896/12.288 MHz, 22.5792/24.576 MHz).
- 75-Ohm BNC Output Impedance: Standardized 75-ohm terminations minimize impedance mismatch and signal reflection over clock cables.
