X1 External Power Supply

When you listen to your audio system, you are quite literally listening to your AC supply. Just as the performance of a car depends on the type and quality of fuel you run it on, so your audio system’s performance can be undermined by a poor quality electrical supply and, within your system, no components are more vulnerable to compromise than the digital and low-level units.

“So yes, The CH Precision X1 does make a difference. A big one! Sadly once you try out X1 along with the P1, there is no going back”

Matej Isak, Mono And Stereo

Product Description

This is one area of technology where size really matters – just not necessarily in the way that you might assume. The critical circuits in your audio system run on DC voltage. The level of that voltage needs to be precise and the level of residual noise it carries needs to be as low as possible. All CH Precision components contain sophisticated power supplies with extensive local DC regulation. But this is one field in which you can never put too much protection between the signal path and the noisy, RF polluted and mechanically intrusive AC supply.

  • Up to two units can be connected to a single X1 (with the addition of a second regulation board)

Internal Topology

  • Dedicated mains filter for each transformer primary
  • Cascades external power supply regulation stage with onboard regulation for superior noise rejection
  • Two oversized power transformers dedicated to the digital and analog power supply sections of the connected unit(s) respectively
  • Allows the connected unit’s mains transformer and rectifier to be powered down, reducing electromagnetic noise and spurious mechanical interference within the audio chassis

Component Compatibility

  • Can be used to further improve the performance of the D1 CD/SACD Transport, C1/C1 Mono DAC/Controllers, P1 Phono-Stage and L1 Line-Stage
  • Housed in the same mechanically grounded enclosure as the rest of the 1 Series units, so that it fits in perfectly with your system

Optional Hardware

  • Second DC Output Board – any X1 can have a second, identical, fully regulated DC output fitted, allowing it to run a second connected unit
  • The X1 External Power Supply is itself a vital optional component in the CH Precision scalable upgrade path. It can be used individually as a dedicated supply, to run two separate components, to run both sides of a dual-chassis component or even as a dedicated supply for a single channel, single chassis set-up

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.
