Description
P8
Eight-channel microphone preamplifer with discrete technology
P8 is equipped with eight identically designed microphone preamplifers. All eight preamps have a discrete design – without ICs, made of individual transistors. This is typical for absolute high-end preamplifers and is one of the main reasons for the outstanding sound.
Besides an analog gain control for adjusting the preamplifcation, each of the eight preamps features an individually switchable phantom power supply (48 V), a PAD switch, a phase inversion function and a switchable analog high-pass flter.
With the optional eight-channel ADAT converter, the purely analog P8 can be digitally connected to an audio interface.
P8 paves the way for high-quality multi-channel recording sessions.
