The VS Studio Violin, Viola, and Mandolin Microphone from AMT is a professional violin / viola / mandolin microphone system that combines the VS microphone with the AP40 preamplifier. The AMT VS microphone is an ultra-miniature cardioid microphone. The microphone features a clamp and arm system for perfect positioning over the sound hole. The AP40 preamplifier converts the microphones to low impedance, it regulates the voltage to each microphone, and with certain models creates a specific frequency curve. The combination results in pristine reproduction of violin / viola in recording applications and sound reinforcement applications.
