Product Description
The problem is that although power amps themselves might appear simple, their job is anything but straightforward. Caught in a sandwich between the output of a line-stage or DAC and the load requirements and sensitivity of any number of different loudspeakers, they must be able to accommodate the widest range of partnering equipment and interface parameters presented to any unit in the audio system. Achieving optimum results under such varied conditions demands a capable and versatile performer – yet as we’ve already established, most power amps offer a single, brute force solution to the problems they face, instead of adopting a more sophisticated response. It’s time for a change – it’s time to meet the CH Precision M1.1, a new-paradigm in power amplification.
What sets the M1.1 apart? It goes without saying that the M1.1’s sonic and musical performance challenges the state-ofthe- art, an incredibly short audio signal path executed with exacting component choices and construction, a massive power supply providing absolute stability and unfettered headroom, capable of meeting both the most delicate and most massive musical demands. But what makes the M1.1 really different is its software driven housekeeping capabilities, a non-intrusive support network that does more than just keep the amplifier unconditionally stable.

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.
