Official description
The NK-72DI is a 500 Series Mic Preamp with built-in DI input. It is based on our popular X-72 500 Series Preamp, with an added Direct Inject (DI) circuitry for high-impedance signal sources like electric or bass guitars. It has a big, punchy sound which also adds a deep, nice, warm coloration to the overall sound. Low frequencies come out tight and punchy, while high end is silky smooth - thanks to those huge Carhill transformers!

This is a great project for a first-time beginner to kit building. The kit is very affordable, but don't let it's low price fool you. This preamp delivers top-notch performance.

An API Rack/Lunchbox or compatible rack is required to supply power and the necessary XLR input and output connections to the SK-1DI module.
