Aune NC1 EVO - Sound Clock / PSU

Aune NC1 EVO is a high-precision OCXO audio clock with integrated linear power supply, developed in collaboration between Aune and a leading manufacturer of crystal-based components for the aerospace industry. This advanced audio clock delivers crystal-clear clock signals and stable power supply, providing a holographically precise soundstage and maximum audio fidelity for audiophiles and professional environments.

NC1 is a perfect companion to the music streamer Aune N5, where NC1 can handle both power supply and optimize the clock signal.

• High-precision OCXO technology: With an OCXO crystal oscillator, NC1 EVO keeps temperature fluctuations within an extremely narrow range, providing a stable and accurate 10 MHz clock signal (>7 dBm @ 50 Ohm). This minimizes phase noise and jitter, making even the smallest microdynamic details in the music audible.

• Crystal-clear signals: The chassis, made of high-quality aerospace aluminum and equipped with multi-layer insulation, ensures clean clock signals without interference – perfect for studio, stage, or high-quality listening environments.

• Precision power supply: The specially designed, low-noise audio transformer and the independently regulated power supply with precise filtering provide absolute silence in the background and an analog warmth reminiscent of vinyl records. Delivers 2 x DC outputs (9 V 2.5 A / 12 V 2 A) to power external devices.

• Universal compatibility: NC1 EVO is not limited to Aune products but can deliver clock signals and power to devices from other brands, making it a versatile solution for anyone striving for a first-class audio experience.

• Audible sound revolution: The improvements are immediately noticeable, both in laboratory measurements and during real listening sessions, with a holographically precise soundstage and exceptional detail.
