This conguration 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. The signal can be linked
through to another amplier, if the keyboard player/ DJ/etc. wants to have a
monitor connected independent of the foldback mix. The ULTRA-DI PRO acts as
both a ground isolator and an unbalanced to balanced converter.
2.3 Converting a microphone signal

Sometimes all that’s available (especially when all other mics are in use) is an
unbalanced high impedance microphone with an unbalanced jack. With the
ULTRA-DI PRO long cable runs to the console can be established without fear
of picking up noise and hum. Just plug the jack into the input and connect the
output to the console’s mic input.
2.4 Tapping a signal from a power
amplieroutput
When no line out is available it is possible to connect an amplier output directly
to the DI4000 (for example, recording direct from a guitar amplier, TV-speaker,
etc). It is possible to connect the output, i.e. an extra speaker output, of up to
3000 Watts to the ULTRA-DI PRO without fear of overloading. Pay attention to the
two -20 dB buttons on the ULTRA-DI PRO! Both must be depressed if an amplier
output is connected to the DI4000 input.

◊ Always make sure the GROUND LIFT is on (no ground link)
when connecting to speaker terminals. This prevents accidental
short‑circuiting of the amplifier output. Also make sure the tip of the
input jack is connected to the red terminal and that the metal housing
of the DI4000 has no contact with other equipment.
