MAGIC LITTLE BOX - The Launcher is not meant to be transparent and clean like other “gain boosters” and audio amplifiers on the market. It was specifically designed to add color and character to your microphones and bring your sounds to life. The Launcher features a custom hand-wound transformer and an analog circuit that provides a warm texture and clarity that will make your mics "open up" and become more three-dimensional in any signal chain.

DREAM IN COLOR - Whether on the stage, in the booth, or in your bedroom, the Launcher is plug and play and gives your dynamic and ribbon microphones the ability to perform incredibly with virtually any interface or preamp by optimizing the sound of your source, boosting your gain by 26dB, and lowering the amount of audible noise in your signal chain.

COUNTDOWN TO THE PERFECT SOUND - The Launcher is the culmination of years of beta testing and feedback from musicians and engineers around the world. We did not stop until the winning combination was found. The Launcher’s custom transformer and proprietary circuit have become one of Soyuz’s most closely guarded secrets.
