"The Global Pre" is a compact high-quality electrostatic microphone preamplifier body designed to be used with vintage German-made M-series interchangeable capsule heads, as well as B-series and VIN-series interchangeable capsule heads made by JZ in Latvia. It was designed as an alternative to expensive historical vacuum tube microphone preamplifiers and fully meets today's high resolution audio recording demands.

 

The electronics are phantom powered, with a linear, Class 'A' discrete solid state transformerless design to provide extremely low self-noise and distortion. Polar patterns and applications fully depend on which capsule head is used.
