Our mission is to create new and exciting devices for use in the recording studio. Our criteria for design is based only on usability, sound and reliability. We believe your ears are the most sensitive test gear on the planet.
NPNG started building Mic Pre-Amps in 1995. Virtually all of the original units are still in use today. The occasional service requests we get are all related to mechanical damage. The circuits are robust and reliable. Built with the finest components available, the QMP4 and DMP2 will yield many years of trouble free use.
