Signal chain:

This chapter details on the signal chain's structure in order to help
you better understand the CH-2.
(1)
INPUT SECURITY:
Designed for maximum optimization of all microphones with
all standard features like +48v (phantom), phase reverse
switch and -20db pad, especially designed for minimum sonic
degradation. All these functions are preformed with special
silver coated toggle switches for maximum rigidness of
operation.
(2)
INPUT TRANSFORMER:
High gain 200 ohm microphone input transformer matching to
a high input impedance. Design for optimal reduction of most
kinds of noise caused when microphones are connected.
Ensure Electromagnetic Compatibility (EMC) standards
compliance. Feature Mu-metal core for minimal harmonic
distortion. Internal electrostatic shields for maximum common
