T ECH 21, THE C OMP ANY Tech 21 introduced the SansAmp™ Classic (the original pedal design) in 1989. Our proprietary circuitry pioneered Tube Amplifier Emulation in professional applications for recording direct and performing live, and created an entirely new category of signal processing.
To achieve the least amount of noise, we recommend keeping the Pre-Amp knob at unity gain or higher. Experiment with the interplay between your instrument and the SansAmp PSA. For best results, do not set the Pre-Amp level lower than unity gain when the Drive knob is at 9 o’clock or higher.
PROGRAMMING Programs 01-49 are factory presets (refer to list on page 22). If you try to save over a factory preset, you will get a flashing “EE” indicating you’re making an error.
REAR P ANEL INPUT 2 SECTION I NPUT 2 JACK 1/4-inch , 4.7megOhm. This high impedance input is designed with piezo pickups in mind to provide maximum output and dynamics. Plugging into Input 2 lets you match the SansAmp PSA’s input cir- cuitry to the signal level being fed into it, assuring the best signal-to-noise ratio and least distortion.
XLR G ROUND L IFT Connects or disconnects the ground circuits between the XLR Direct Out of the SansAmp PSA and the mixer. We recommend starting with the ground lifted (button in). If necessary, connect the ground (button out). MIDI M IDI I N This jack receives MIDI signals, including Program Change commands and MIDI data dumps.
