A New Standard of Accuracy and Stability

In any digital audio system, the rate at which digital data is transmitted and received is of the utmost importance. Specifically, all devices in the digital signal path must be synchronized in order to provide a coherent presentation. Therefore, for the ultimate experience in clarity, transparency, focused imaging, and natural realism, your system’s digital source, DAC, and any other upsamplers or converters should all receive the same synchronized clock signal from an ultra precise and stable source.

The Aurender MC20 is both a Master Clock and Word Clock generator that is inspired, developed, and designed to deliver an exceptionally high level of digital audio realism from a connected music server and/or D/A converter. Thanks to the MC20’s superior timekeeping, jitter is reduced to infinitesimal levels resulting in the ultimate timbral purity and rock-steady placement of instruments within your system’s soundstage.

At the heart of the MC20 is a rubidium module that generates a 10MHz master clock reference signal. A rubidium clock is employed for its superior accuracy and stability in both the long and short term for ultra-low jitter. Additionally, MC20 contains two discrete OCXO word clock modules for generating the frequencies 44.1 kHz and 48 kHz. MC20 will independently and simultaneously supply the four 10MHz master clock outputs and four Word Clock outputs (2 at 44.1 kHz and 2 at 48 kHz) for unprecedented versatility with a wide variety of Aurender and third party equipment.

Rubidium 10 MHz Clock Module

The rubidium clock module employed in the MC20 is an exceptionally stable and accurate design that establishes a new low level of phase noise and jitter. Its flawless performance delivers a new level of vivid clarity with a three-dimensional width, depth, and height to the sound field it creates. The reduction of jitter and phase noise removes any trace of “digital glare,” and instead provides an analog-style warmth and naturalism to any digital audio source.

Discrete OCXO Clocks

Two separate channels of OCXO Word Clock generators with 75Ω and 50Ω ports on each channel.

Many DACs and sources accept only Word Clock input as opposed to 10MHz Master Clock input. For connectivity with such equipment, 2 channels of discrete OCXO driven word clock outputs are included. Set one to 44.1 kHz, and the other to 48 kHz (and multiples thereof).

Synchronized Perfection

An innovative SPDIF sync channel enables automatic synchronization of word clock output depending on the content being played.

Connectivity

Connect MC20 to an Aurender source + a DAC with clock input for the maxiumm benefit. However, even if your DAC does not have a clock input, synchronizing your Aurender transport with MC20 is still a revelation.
