The Behringer ULTRA-DI DI20 features electronically servo-balanced
standard inputs and outputs. The circuit design is equipped with
automatic hum suppression for balanced signals and operates
problem-free even at high levels. Externally induced mains hum is
thus eciently suppressed. The servo function automatically detects
unbalanced pin connections and changes the nominal level internally
by 6 dB so that there is no dierence in level between input and
outputsignals.
