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 M1.1, 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.

Option board:
Analog_Buf: Monaural analog input buffer board à CHF 1'700.-
Three analog inputs - XLR, RCA and BNC - are provided on a single board. A pass-through XLR male connector allows a direct connection to another A1 amplifier.
Can be factory ordered for Left or Right channel.
Factory built-in (1x), second board is needed for stereo operation.
