Behringer ULTRA-DI DI100 [10/12] Converting a microphone from high impedance unbalanced to low impedance balanced

10 ULTRA-DI DI100 User Manual

2.3 Converting a microphone from high impedance

unbalanced to low impedancebalanced

Sometimes all that’s available (especially when all other mics are in use) is a unbalanced high

impedance microphone 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 console’s mic in.

2.4 Tapping a signal from a power amplieroutput

When no line out is available it is possible to connect an amplier output directly to the DI100

(for example, recording direct from a guitar amplier, 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 amplier output is connected to the DI100 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 DI100 has no contact with other equipment.
