Summum de musicalité et de technologie, l'Amplificateur de Puissance CH Precision M1 est un instrument de musique d'exception. Il est configurable et adaptable à l'infini. En mode MONO bridged il est capable de fournir 700 Watts en continu sous 8 Ohms! Tous les fabuleux instruments de musique CH Precision sont développés et fabriqués en +Suisse+.

Being able to truthfully and accurately reproduce today’s highest quality recordings has never been more challenging. Only when each element of the reproduction chain is able to precisely recreate the music’s time and level information can a genuine emotion be felt. The M1, CH Precision 1 Series’ most powerful amplifier was developed with this in mind. The leading-edge technological advancements implemented on the A1 were further refined, among others is the ExactBias circuitry and a finer loudspeaker matching.

Specified at 200W RMS into 8Ω in monaural mode, 2x 200W RMS into 8Ω in bi-amplification / Stereo modes and 700W RMS into 8Ω in bridge mode, the M1 houses a dedicated 2200VA power transformer providing the amplifier output stage with ample energy to accurately and effortlessly drive the most demanding loudspeakers.
