BEHRINGER is constantly striving to maintain the highest professional
standards. As a result of these efforts, modifications may be made from
time to time to existing products without prior notice. Specifications and
appearance may differ from those listed or shown.
2.3 Converting a microphone from high impedance unbalanced to low impedance balanced
Sometimes all thats available (especially when all other mics are in use) is a unbalanced high impedance micro-
phone with an unbalanced jack. With the ULTRA-DI 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 consoles mic in.
2.4 Tapping a signal from a power amplifier output
When no line out is available it is possible to connect an amplifier output directly to the DI100 (for example, recording
direct from a guitar amplifier, 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 without fear of overloading. Pay attention to the two -20 dB buttons on the ULTRA-DI! Both
must be depressed if an amplifier output is connected to the DI100 input.
Fig 2.3: Connection to an amplifier output
+ 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 DI100 has no contact with other equipment.
