12 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. 2.2 Converting the output of a Keyboard / DJ-mixer / Headphone plug L In Out R In Out Microphone Inputs panned To Monitor Left & Right 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.
