The unit offers a stepped input gain knob to ensure repeatability. It'll provide you with up to 70 dB of gain. You'll find controls for phantom power and polarity, while a Hi-Z switch will allow you to plug in your favorite guitar or bass for a DI recording. The preamp utilizes a CineMag transformer for that classic velvety '73-style sound. The output control is situated after the transformer. So, if you wished, you could drive the signal hard with the gain knob for a harmonically rich tone, then lower the output knob to avoid clipping your digital converter downstream.
