4 MKII Passive Controller.
Design
PC
●
4 was designed with the audio purist in mind, a minimalist design utilizing the highest quality parts
to yield unmatched transparency.
Similar to previous VPC models, the audio path is completely passive, passing only through an input
switch and potentiometer. For PC
●
4, we sought only the highest grade components… Cardas Input &
Output jacks, Grayhill hermetically sealed switches with gold over copper contacts, and laser-trimmed
ALPS Blue Velvet potentiometer. Improved layout and 2 layer/3 oz. copper circuit board with improved
layout, all housed in a heavy machined aluminum chassis.
