User manual BEHRINGER DI20

[. . . ] The input impedance of the DI20 is extremely high, and it absolutely does not influence the signal flow through the DIbox. The output impedance is balanced and always very low, whereby the signal is far less prone to being affected by noise. + To prevent damaging your loudspeakers, first connect the DI-box and then hook up the respective channel. The same goes for alternating between battery and phantom power operating modes. 2 ULTRA-DI DI20 1. 1 IN input is used to connect unbalanced as well as balanced signal sources to channel 1. [. . . ] 2. 2: DJ-mixer ß DI-box ß mixing console 2. CONNECTION OPTIONS 5 ULTRA-DI DI20 This configuration 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 amplifier. 3. AUDIO CONNECTIONS The BEHRINGER ULTRA-DI DI20 features electronically servobalanced 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 efficiently suppressed. The servo function automatically detects unbalanced pin connections and changes the nominal level internally by 6 dB so that there is no difference in level between input and output signals.
