Description
The ADDAC712 is a dual-channel discrete amplifier module derived from a 1970s preamp design. It features two gain stages with independent controls and can process modular signals or external sources like keyboards and guitars, delivering progressively colored saturation and hard clipping at higher levels. A bypass switch selects between the top gain stage or a direct path, while an output stage with clipping indicator lets you manage overall level independently.
