  • Bemerkung

  • The Chameleon Amplifier was a groundbreaking power amplifier introduced in 1990 by Malcolm Hill.

    Renowned for its high power density and compact design, the Chameleon challenged the industry's top performers.  

    Key Features

    • Power output: 1000W RMS per channel into 4 ohms
    • Frequency response: 10 Hz to 20 kHz ±0.5 dB
    • Total harmonic distortion: <0.01% at 1 kHz at full power
    • Signal-to-noise ratio: >110 dB unweighted (20 Hz to 20 kHz)
    • Slew rate: >60 V/μs

    Unique Design Elements

    • Dual-mode operation: Can function as either a voltage source or current source amplifier
    • Adaptive slew limiting: Prevents transient intermodulation distortion
    • Soft clipping: Gradually reduces gain to prevent harsh distortion
    • Dynamic bias control: Optimizes efficiency based on signal level

    Advanced Circuitry

    • Output stage: Uses a complementary bipolar transistor design with multiple parallel devices for high current capability
    • Protection systems: Includes DC offset, thermal, short circuit, and clip limiting
    • Input stage: Fully balanced differential amplifier for noise immunity
    • Signal processing: Features subsonic filter and optional high-frequency rolloff

    Construction and Serviceability

    • Modular design: Allows for easy servicing
    • Forced-air cooling: Ensures efficient heat dissipation
    • Toroidal power transformer: Reduces electromagnetic interference
    • Balanced and unbalanced inputs: Offers flexibility for various audio sources

    The Chameleon amplifier's innovative design and advanced features made it a standout product in the professional audio market. Its ability to deliver high power and exceptional audio quality in a compact form factor solidified its reputation as a benchmark for power amplifiers.
