Studio Electronics Boomstar Modular Amp Module
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, the 5089, and the 3003 are Class A circuits. They draw 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. The 4075 draws equally from both rails, and is more immune to hum. Like our filters Boomstar Modular AMPs are hand-built entirely in the U. S. of A - just ask Rachael Herbison!
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 Plus" 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 overdirve / saturation
OUTPUT - Adjusts the audio output
INPUT - Audio input
ST1 CV1 - Stage 1, control voltage 1 input
