Aurender MC20 Master Clock

Aurender MC20 Master Clock

The Aurender MC20 Master Clock is a technologically advanced and precision-oriented component engineered for audiophiles who demand exacting timing and synchronization in their audio systems. Its SPDIF Sync Input features a Coaxial BNC connection with 75Ω impedance, ensuring robust signal transmission. For clock output, the MC20 incorporates a Rubidium Master Clock that delivers a 10MHz signal through two 75Ω and two 50Ω outputs, maintaining a stable 0.7Vrms signal with a tolerance of ±10%. Additionally, it offers Word Clock outputs, providing CH. A and CH. B with two 75Ω connections.

This device presents a forward-looking approach with reserved USB connectivity for potential future use, catering to evolving audio technologies. The MC20 is equipped with a comprehensive set of LED indicators, including Clock LED, Sync LED, and 10 Multiplier LEDs for each channel, enhancing user control and status monitoring. The Select Button allows easy clock and multiple selection, further simplifying the user experience.

In terms of clock precision, the Rubidium-based clock within the MC20 boasts remarkable Phase Noise ratings of less than -130dBc/Hz at 10Hz and less than -140dBc/Hz at 100Hz, guaranteeing minimal signal interference. Furthermore, it exhibits exceptional short-term stability, with frequency accuracy reaching less than 2×10⁻¹¹ for 1 second, less than 1×10⁻¹¹ for 10 seconds, and less than 2×10⁻¹² for 100 seconds. The inclusion of an OCXO-based clock with Phase Noise performance of less than -90dB/Hz at 1Hz, less than -115dB/Hz at 10Hz, less than -127dB/Hz at 100Hz, and less than -143dB/Hz at 1kHz ensures reliable timing accuracy.

The MC20's design is practical and accommodating, with dimensions of 430mm x 106mm x 370mm (unit only) and 127mm in height with the foot. This device is 16.9 inches x 4.2 inches x 14.6 inches in size (unit only), with a height of 5.0 inches with the foot. Its robust build weighs 20.3kg (44.7lbs), and it accepts input voltages of 110V and 220V, making it adaptable to various power environments. The MC20's power management is efficient, consuming only 5.7W in standby mode, while startup draws 160W during warm-up and subsequently reduces to 58W in a locked state. This ensures that the MC20 functions optimally without unnecessary power consumption.
