T10 10MHz Time Reference

In digital audio, precision in the time domain is not simply desirable but essential. Every sample, each microscopic data point, must arrive in perfect sequence and at precisely the correct interval. The C10 Master DAC already incorporates state-of-the-art clocking, improving further when paired with the C10 Conductor. Adding the T10 Master Clock elevates timing accuracy to an even higher standard, unlocking greater clarity, coherence, and musical expression. The T10 produces a hyper-accurate, low-jitter clocking signal with vanishingly low phase noise, ensuring digital data is transferred and converted with unwavering stability.

T10 10MHz Time Reference

Pairing a transport with a separate DAC can introduce timing errors caused by independent clock domains. Even slight discrepancies can result in jitter, diminishing resolution, and musical coherence. The T10 Time Reference Clock addresses this by providing an ultra-stable timing source for the entire system. Its 10MHz oven-controlled oscillator (OCXO) is renowned for low phase noise and is thermally stabilized within a solid billet aluminum block to ensure consistent performance. Referencing all digital components to the T10 reduces timing errors, unlocking deeper resolution, spatial precision, and musical flow.

T10 10MHz Time Reference

Unlike other CH Precision units, the T10 offers only one option – its unique GPS input. Instead, the T10 is itself the option, offering improved performance with all CH Precision digital components (the D10 and C10) a vital part of their scalable, upgradable topology.

CH-Control App

Meet the CH-Control App – a control application that allows users direct access to every aspect of their CH system’s set up and use via any Android portable device. The software control systems used to set and monitor the operational parameters of each and every CH component offer the perfect opportunity for remote operation via a portable App.

To use the CH-Control App, all you will need is an Android device and to connect your CH components to an Ethernet network. That can be done either through the Ethernet control board fitted as standard to all CH units, or through the network streaming board that can be installed in C1.2, C1.2 Mono or I1 units. We would always recommend using a dedicated tablet and network for your music streaming and system control requirements.

Once your CH system is all hooked up, the App gives you touch screen access to every setting on every CH component, from your listening seat, a huge benefit when it comes to whole system set up or optimization for individual recordings. Either way, the CH-Control App allows you to make easier and more accurate judgements: Total control, quite literally at your fingertips.

The features of every CH product are accessible through the CH-Control App:

  • Built-in UPnP controller to stream dematerialized music, create playlists, etc.
  • Set volume level, select sources, reverse phase, mute, etc.
  • Access to all the advanced set-up parameters in every CH product.
  • Works on a standard Ethernet network.
  • The CH-Control App is freely available on Google Play or directly on our website.
