    The Studio Electronics AMP is a EuroRack amp module utilising Class A circuitry.

    Main Features

    • All analogue design
    • Class A circuitry
    • Drive circuit from the Boomstar desktop synth
    • 6 patch points

    The amplifier (AMP) is a 2 stage Class A discrete design using 3 pairs of hand matched transistors. Envelope is usually applied to ST1/1. ST1/2 goes thru an attenuverter and can be used for envelope or modulation. ST2/1 goes to the 2nd stage, and is typically used for volume control. ST2/2 goes thru an attenuverter and is typically used for modulation.

    The AMP is a Class A circuit. It draws more current from the +12 rail than from the -12 volt rail. If the system power supply is under-sized, hum or buzz may be heard. In that case, larger filter capacitors and/or a larger power transformer will be needed.

    Potentiometer Potential
    Two attenuverters and two attenuation pots control the INPUT, ST1 CV2, ST2 CV2, and OUTPUT, delivering smooth, detailed, and complex expression.

    Switch it Up
    Uber useful continuous hypnotic DRONE for endless sustain/release, and DRIVE—the overdrive circuit from the Boomstar desktop—for last stage energy, bite, soft clipping, and gonzo '70's era 'Distortion' + crunchy fuzz.

    Patch it Up
    Six patch points: INPUT, ST1 CV1, ST1 CV2, ST2 CV1, ST2 CV2, OUTPUT direct the deepest manipulation.

    All Controls and Patch Points
    INPUT – Adjusts the audio input.
    ST1 CV2 – Adjusts stage 1, control voltage 2.
    ST2 CV2 – Adjusts stage 2, control voltage 2.
    DRONE – Sustains the last note received.
    DRIVE – Final output stage overdrive/saturation.
    OUTPUT – Adjusts the audio output.
    INPUT – Audio input.
    ST1 CV1 – Stage 1, control voltage 1 input.
    ST1 CV2 – Stage 1, control voltage 2 input.
    ST2 CV1 - Stage 2, control voltage 1 input.
    ST2 CV2 – Stage 2, control voltage 2 input.
    OUTPUT – Audio output.
