1. Introduction
Thank you for choosing the QuadMic. This unique Mic Preamp allows to connect any kind of
microphone to any line level inputs. Thanks to the option of battery-powered operation, the
QuadMic makes an ideal companion to the Hammerfall DSP System in mobile recording situa-
tions. But excellent signal/noise ratio, sophisticated discrete Class-A technology, and lots of
professional features make the QuadMic your first choice even for studio use!
