Overview

dCS Rossini Master Clock – Reference Digital Audio Clock

Precision timing for a more revealing musical experience.

The dCS Rossini Master Clock is a dedicated precision clock designed to optimize the performance of compatible Rossini digital audio components.

Drawing upon decades of digital audio engineering, the Rossini Master Clock provides a highly accurate and stable timing reference that allows connected components to operate in synchronization.

Digital audio depends on precise timing during the conversion process. By supplying a dedicated external clock signal, the Rossini Master Clock helps compatible components maintain consistent timing and minimize the effects of clock-related errors.

The result is a digital playback system designed to deliver greater resolution, precise spatial imaging, and a more natural presentation of music.

Engineered as the ideal companion to the Rossini APEX DAC and Rossini APEX Player, the Master Clock offers a straightforward way to expand a Rossini system while maintaining the elegant simplicity of the range.

Why Add a Master Clock?

Accurate timing is essential to digital audio reproduction.

The Rossini Master Clock provides an independent reference signal that compatible components can use to synchronize their operation, reducing reliance on their internal timing references.

With three independently buffered outputs, it offers flexibility for configuring a digital playback system while maintaining precise synchronization.

Pair it with the Rossini APEX DAC or Player to create a dedicated two-component digital source.
