NPNG QMP4-NW Preamp

The NPNG QMP4-NW Preamp is a hand built exciting 4-Channel preamp designed with your ears in mind. Delivering usability, sound quality and reliability NPNG QMP4-NW is a preamp worthy of any studio.

NPNG's mission is to create new and exciting devices for use in the recording studio. The criteria for our designs are based only on usability, sound quality and reliability. We believe your ears are the most sensitive “test” gear on the planet.

The LPS-41 Power Supply is designed to power either a dual or a quad channel pre amp. It features almost 40,000 uF of capacitor filtering and is fully regulated. AC ripple and noise is less than 150uV rms on all DC Rails. It utilizes both EMI/RFI filtering on the AC Mains input and is internally surge protected. All the DC rails are fuse protected as is the AC Mains. The mains voltage can be changed from 120VAC to 220-230VAC operation by an internal toggle switch.
