The 9754 is used to match low-level signals such as those from microphones to the line-level (plus) signals anticipated by modern modular synthesizers, or, just to perform a general signal boost. Inputs to the module may be balanced or unbalanced (two or three circuits), via XLR plugs, 1/4" phone plugs, or 1/8" phone plugs (tip-sleeve phone, aka 3.5mm mono). An on-board regulated +12V DC or an optional externally-supplied voltage can be selected as an output power source for phantom-powered microphones. The module has an adjustable gain control (to x1000) and an unbalanced 1/8" phone connector output.
