Behringer Ultra-DI DI100 User Manual

ULTRA-DI DI100 User Manual

This figure shows the standard application of any direct injection box. The signal to the 

amplifier is unaffected, it is just tapped off to be routed to the microphone input of the mixer. 

Especially bass guitars benefit from this application. It is difficult to find a microphone which 

handles high level low frequencies well and with a linear frequency response. Using the 

ULTRA-DI will give you clean and crisp sound. Connect the ULTRA-DI after any effects devices 

so that their effect will be heard over the P.A.-system or on the recording. If the mixer provides 

phantom power between 20 V and 52 V, the internal battery of the DI100 will automatically be 

detached. You should chose this possibility whenever possible to save battery power.

Fig 2.2: DJ-mixer

 2 x DI 

➟

 mixer

This configuration can be used with a keyboard, DJ-mixer, headphone output, drum kit or 

any (stereo or mono) line source. In all cases where you want to run long lines, for instance 

to the FOH (Front Of House) desk. In most cases the best setting is achieved by depressing 

one of the -20 dB pad buttons to avoid overloading the FOH desk input. The signal can be 

linked through to another amplifier, if the keyboard player / DJ / etc. wants to have a monitor 

connected independent of the foldback mix. The ULTRA-DI acts as both a ground isolator and 

an unbalanced to balanced converter.
