This conguration is recommended when
using a DJ-mixer or another signal source,
which sends an unbalanced line level signal.
In addition, if you need a separate monitor
signal, the line level signal can be sent to
another amplier.
4. Audio Connections
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 eciently suppressed. The servo
function automatically detects unbalanced
pin connections and changes the nominal
level internally by 6 dB so that there is
no dierence in level between input and
outputsignals.
For unbalanced use, pin 1 and pin 3
have to be bridged
1 = ground/shield
2 = hot (+ve)
3 = cold (-ve)
