ULTRA-DI PRO DI800
FUSE COMPARTMENT/VOLTAGE SELECTION: Before
plugging the unit into a power socket, please make sure
you have selected the correct voltage. Faulty fuses must
be replaced with fuses of appropriate rating without
exception. Some units feature a fuse compartment that
can be operated in two different positions, allowing
alternating between 230 V and 120 V. Attention: when
using the unit outside of Europe (running on 120 V), you
have to implement a fuse with a higher rating (see
chapter 5 “SPECIFICATIONS”).

3. APPLICATIONS

3.1 Connecting a guitar/bass signal

Fig. 3.1: Guitar ß DI-box ß 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.
3.2 Converting output signals of a keyboard,
DJ mixer, etc.

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.

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.
