MP573

The MP573 is a two stages, single ended class A preamp, based on the design that was originally used in the Neve 1290/1073 modules, that has been adapted to the '500' format of API.

Just install it in your API* compatible LunchboxTM rack and start recording.

The sound of the MP573, like its model is full, silky, detailed and musical, slightly larger than life, very complimentary to a digital recording environment.

The MP573 is great on vocals, acoustic instruments and generally all close miked sources that need to be pushed forward in the mix.
