CH Precision M1.1 Amplifier. Factory Certified with full warranty

We have a CH Precision factory certified M 1.1 stereo amplifier available. Probably the most versatile/configurable amplifier ever made.

The combination of power and finesse is unmatched from any amp under $100,000 IMO.

Being factory certified, this unit has the same 2-year warranty from CH Precision as a new M1.1
The CH factory assures that every parameter of any certified product performs to new specs.

You are invited to visit and listen for yourself in our demo room.
 

Physical And Conceptual Modularity

• Modular input boards to match system topology
• Output stage can deliver 200W RMS into 8 Ohms stereo, 200W mono (high-current), 700W mono (bridged) or 200W bi-amped (single input, differential channel gain and global feedback settings)

Analog Input Stage

• Pure class A, fully symmetrical circuit topology
• Fully discrete, ultra low noise, high slew rate design
• DC coupled with no series capacitors in the audio signal path

Analog Output Stage

• Pure class A ultra low noise driver and class AB pure follower power stage
• Patented ExactBias circuitry ensures constant bias, independent of room temperature. Monitors output power, temperature and amplifier loading
• User configurable display will show amplifier status, power output etc
• Customized Argento internal wiring and loudspeaker binding posts (accept spades or banana plugs)

Power Supply

• 2200VA power transformer mounted on separate, mechanically isolated chassis bed to eliminate mechanical vibration
• Magnetically and electrostatically shielded transformers to reduce noise and EM interference
• Hyper fast, soft recovery diode bridge rectifiers meet dynamic demands without strain
• Total of 250,000uF custom-built, ultra low ESR reservoir and filtering capacitors

User Adjustable Global Feedback Ratio

• Ratio of Global to Local Feedback can be adjusted from 0% to 100%, in 10% steps via the user interface or control app
• Allows user optimization of amplifier/speaker interface, especially low frequency damping relative to speaker/room interaction
• Each channel can be adjusted individually to control specific drivers/ranges in bi-amplification modes

User Adjustable Input Gain

• Input gain can be user adjusted to accommodate input signal level and overall system gain 24dB range in 0.5dB steps
• Optimizes system noise floor and dynamic range
• Accommodates variations in loudspeaker sensitivity and room size

Light Touch Protection

• No output relay in signal path; full short circuit protection
• Non-invasive output stage voltage, current and temperature monitoring protects your amplifier – and your speakers
