AUNE NC1 EVO: the heart of time

In the world of high-quality digital audio, timing is everything. The precision with which digital data is synchronized directly affects sound quality, and it is on this principle that the AUNE NC1 EVO is based, a Master Clock Audio OCXO capable of bringing tangible and immediately perceptible benefits to listening.

OCXO Technology: absolute clock signal stability

The heart of the AUNE NC1 EVO is an OCXO (Oven‑Controlled Crystal Oscillator) that keeps the crystal at a constant and tightly controlled temperature, drastically reducing oscillation variations due to the external environment. The result is an extremely stable and precise clock signal, with a significant reduction in jitter and phase noise.

In sonic terms, this translates into greater focus and micro dynamics, with more natural transients and better temporal coherence between the various instruments. But NC1 EVO is not just a dual-output clock generator, but also a sophisticated linear power supply capable of providing two different power voltages at 9V or 12V (switchable via internal dip switch) that can power both Aune products and any other. NC1 EVO is designed to operate even in electrically complex environments. The aerospace-grade aluminum chassis, combined with a multi-layer insulation system, protects the internal circuit from electromagnetic and electrical interference. This construction approach ensures that the digital clock signal remains undisturbed, preserving integrity and precision even in the most critical conditions. The temporal base of the entire system thus remains stable and reliable at all times. NC1 EVO uses the same enclosure as N5, Aune's streamer, and it matches both in terms of clock and power supply. On the 3” front display, the internal temperature indication, strictly monitored, the used sockets, and the selected voltages for the outputs are shown.

Toroidal linear power supply: the basis of a natural sound

A product like this cannot do without a high-quality power supply. AUNE NC1 EVO integrates a toroidal transformer made ad-hoc with a separate branch for the OCXO quartz alone, and two others for the DC outputs of 9V 2.5A or 12V 2A to provide clean and interference-free energy from both the power grid and mutual

Total versatility and wide compatibility

One of the great strengths of the AUNE NC1 EVO is its extensive compatibility. It can be connected not only to Aune products but can provide clock signals and power to devices from many other brands, thanks to the 10 MHz > 7 dBm clock signal at 50 Ohm on BNC

A significant step

The adoption of the Master Clock OCXO AUNE NC1 EVO produces immediately noticeable improvements, significantly reducing jitter, a concrete intervention, in short, on the digital system. A dedicated external clock indeed offers a significantly superior temporal base, with constant performance over time and not influenced by external agents, temperature variations, or highly disturbed power supplies. Investing in an external clock means, in short, improving every digital component connected to it. And we are not talking about excessive investments, as thanks to current technologies it is possible with a modest expense to bring home, as in the case of this NC1 EVO, both a clock and a sophisticated power supply.

AUNE NC1 EVO should not be seen as a simple accessory, but represents one of the most intelligent and complete solutions available today.
