M1.1

About the M1.1

The CH Precision M1.1 monoblock amplifier redefines high-performance audio amplification with its sophisticated design and versatility. Each unit contains two power amplifiers and can be configured in five different modes including stereo, monaural, bridged, passive bi-amplification, and active bi-amplification. It delivers up to 350W per channel into 4 ohms in stereo mode and up to 1200W in bridged mode. The amplifier features a massive 2200VA transformer, discrete analog stages with no capacitors in the signal path, and a JFET-based fully differential input stage running in class-A with class-AB output stages. It uses OnSemiconductor ThermalTrak devices for precise temperature monitoring to maintain bias stability. The M1.1 also includes a DSP-based protection system for speaker safety. Its software-driven housekeeping capabilities allow dynamic adaptation to signal and load changes, ensuring stability and optimal performance. The amplifier is handmade in Switzerland, weighs approximately 165 pounds, and is known for its exquisite sound quality, combining power and finesse with cutting-edge technology and understated luxury design.
