Fig. 3.1: Guitar DI-box guitar amp/mixer
This illustration shows the standard application of a DI-box. The signal feeding the
amplifier remains unchanged; it is simply taken and routed into the amp. The low-
impedance balanced signal is forwarded to the mic input of the mixing console.
This application has its advantages particularly with bass guitars, because very few
microphones can linearly transmit bass frequencies with high signal levels. If you
are using effects, insert the DI800 after the effects device, so that you can monitor
the effects via the PA system or the recording as well.

This configuration lends itself to use with a keyboard, DJ mixer or other mono/
stereo signal sources with line level, particularly when using long cables
(e.g. connecting to a FOH mixer). The signal can be looped through to another
amplifier via the link output. Thus, you get a monitor signal that is independent
from the actual FOH signal (useful for keyboarders, DJs etc.).
3.3 Converting a microphone signal
Average-quality microphones often feature unbalanced, high-impedance
outputs. The DI800 lets you wire such mics to the mixing console using long
cables without running the danger of inducing hum or interference noise. To this
end, the microphone has to be connected to the input of the DI-box, and the
DI-box’s output needs to be connected to the mic input on the mixing console.

3.4 Taking a signal from a speaker output
Sometimes, you want to take a signal directly from a speaker output,
even though just one speaker output is available. By using the -30 dB switch on
the DI800, you can connect your mixing console to an amp output (up to 3,000
Watts into 4 Ohms), without worrying that the DI800 will be damaged due to
overload! If you are using a tube amp, you should connect a speaker or a similar
load resistance to the LINK output.

Before connecting to a loudspeaker connector, please make sure that
the GROUND LIFT switch is in the ON position (no ground connection).
This prevents accidental shorting of the amp output. Besides, the tip
of the input connector should be connected to the speaker connector
marked with red. The metal casing of the DI800 should in no case have
physical contact to other equipment.
