The GKit Baby Pre is a two-channel, standalone mic preamp kit that's designed to provide a rewarding and educational building experience for beginners. The Baby Pre was originally designed by a team of audio educators at McGill University to teach their students the basic concepts of electronics. We're thrilled to make this great piece of gear and educational opportunity available to everyone.

 


BabyPre built by a student

Each of the two channels has a gain control as well as push-buttons for +48V phantom power, a high-pass filter, pad, and a Colour stage. The inputs and outputs are on balanced XLR connectors, and the power supply uses an external “wall wart” AC transformer to ensure there are no potentially hazardous voltages during assembly and testing. The GKit baby pre will surprise you with its quality and versatility in such a small package.
