ULTRA-DI DI20 Welcome to the BEHRINGER family! Thank you for the confidence you have placed in us by purchasing the ULTRA-DI DI20 professional active 2-channel DI-box/splitter. On stage as well as in studios, it is sometimes advantageous to connect certain sound sources directly to the mixing console. Since many instruments (keyboards, for example) dont have balanced outputs they require a DI-box. Sometimes, even guitars cant be directly connected to mixing consoles because their impedance is too high.

+ + 4 ULTRA-DI DI20 You should only use the ATTENUATION switch when your DI20 rather than the mixing console preamp begins distorting. Otherwise refrain from using this function to avoid excessive dampening. The MODE switch lets you select the operating modes of the DI20. In the 2-CH mode, two independent signals can be connected to channels 1 and 2 respectively.
ULTRA-DI DI20 BATTERY COMPARTMENT To access the battery compartment, loosen the screw on the rear. 2. CONNECTION OPTIONS 2.
