Welcome to BEHRINGER!
DI stands for Direct Injection. On stage or in the studio there are sources you want to connect to your
mixer that are not equipped with a suitable connection. Keyboards seldom have properly balanced
outputs. Guitars cannot be directly plugged into a mixer and placing a microphone in front of
a backline is not always ideal. A microphone picks up ambient noise such as other instruments.
Lowfrequencies (such as from a bass guitar) are especially dicult for a microphone to handle.
A DI-box makes it possible to tap a signal from a high impedance unbalanced line, for instance
the signal from a guitar to a guitar amplier, and inject it directly into the mixer’s input
without having to use a microphone. But that’s not all, there are lots of situations where you
want to inject the signal coming from an unbalanced source directly into your mixer and
preferably balanced, too. Thatisthe application of a Direct Injection box.
Impedance is the electrical frequency dependent resistance of a device combined with its
phase response. It is a literally complex matter. That is why a good DI-box is distinguishable
from a bad one. As with a power amplier and speakers the impedance to a device determines
the performance. With a good power amplier the load impedance only aects the maximum
power output. Whereason some other devices the impedance governs other properties as well.
With a transformer as used in a DI-box, the connected impedances (in and out) inuencethe
bandwidth, frequency response, distortion, etc.
There are two basic types of DI-boxes, passive and active. Both active and passive DI boxes are
designed to be connected to the console’s microphone input. Apassive DI box has the advantage
of being slightly lower in cost (lesselectronics, no battery facility) but their performance is highly
dependent on the connected impedances. When the impedance on the mixer side of a passive
DI-box changes, the impedance on the input changes also. Notonly that, the frequency response
changes, too. A passive DI-box only works well at specied connected impedances, high in and
low out, which means that they only work in a standardapplication.
Active DI-boxes don’t have such restrictions. The signal coming from the input is buered
with an amplier. The input impedance of the ULTRA-DI is ultra-high so it doesn’t aect
the signal throughput at all. The output impedance of the Ultra-DI is balanced and very low
so that it is much less susceptible to picking up hum and noise. This way, the impedance
for the signal source is independent from the impedance of the used mixer and vice versa.
There is no sound alteration. The transformer used is BEHRINGER´s renowned OT-1 witch
guarantees distortion free, clean sound and a at frequency response. Furthermore the
BEHRINGER ULTRA-DI can be powered by your console’s phantom power or by battery and
switches automatically between these two.

7ULTRA-DI DI100 User Manual
◊ To avoid switching noise, you should mute the desk channel before activating
the DI100. Same applies when switching between battery and phantom power
and vice versa.
The design of the DI100 includes four sturdy rubber feet which protect the unit
(even during a unplanned drop) and allow cables to run underneath. Italsoprovides literally
a “ground lift” so that the unit can be stacked on top ofanother unit and other equipment
without creating ground loops.

(7) (6) (8) (5)(2) (3) (4)
Fig 1.1: Front & Rear DI100
(1) With the ON/OFF switch you can switch the battery power on and o to preserve
battery life. Switched o the ultra-di will still work on phantom power. Switchedon,
the ULTRA-DI will automatically switch between battery and phantom power. When the
DI100 is operating on battery power the on/o LED will ash once every few seconds,
when operating on phantom power the LED will light up continuously.
(2) INPUT. Connect the source to this ¼" jack to receive the signal.
(3) To provide maximum exibility the ULTRA-DI is also tted with an unbalanced XLR input
to connect the source.
(4) LINK OUT. This is the unbalanced parallel output of the ULTRA-DI. Connectthis to the
input of the backline or monitor amplier.
◊ The ¼" jacks (input and link out) and the Input XLR are wired parallel, so any
connection as input will give the same performance.
(5) The -20 dB attenuation switches greatly increase the operating range of the ULTRA-DI.
From the low-level signals of a high impedance microphone or guitar to the hot speaker
terminals of a P. A. amplier. Depressing both will give 40 dB attenuation.

8ULTRA-DI DI100 User Manual
◊ Only use the -20 dB switches if you are sure the ULTRA-DI is clipping (overloading)
and not your mic pre-amp. Always use as little attenuation as possible to get the
best possible signal-to-noise ratio.
(6) OUTPUT. This is the balanced microphone level output of the ULTRA-DI. Connection to
the microphone input should be made with a standard high quality balanced cable.
◊ Never connect pin 2 or 3 to pin 1 and never disconnect the shield from pin 1,
or the unit will not work on phantom power.
(7) Use the GROUND LIFT switch to either connect the ground of input and output or
keep them completely separate. Depending on the grounding of the connected devices
linking or disconnecting will reduce hum or prevent ground loops. GROUND LIFT ON
means no interconnection.
(8) BATTERY COMPARTMENT.Loosen the screw to open the compartment and to replace
the 9V battery. When the ULTRA-DI is switched on battery power the LED blinks, when it
stops blinking it is time to change the battery.

This gure shows the standard application of any direct injection box. The signal to the
amplier is unaected, it is just tapped o to be routed to the microphone input of the mixer.
Especially bass guitars benet from this application. It is dicult to nd a microphone which
handles high level low frequencies well and with a linear frequency response. Using the
ULTRA-DI will give you clean and crisp sound. Connect the ULTRA-DI after any eects devices
so that their eect will be heard over the P.A.-system or on the recording. If the mixer provides
phantom power between 20 V and 52 V, the internal battery of the DI100 will automatically be
detached. You should chose this possibility whenever possible to save battery power.

This conguration 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. In most cases the best setting is achieved by depressing
one of the -20 dB pad buttons to avoid overloading the FOH desk input. The signal can be
linked through to another amplier, if the keyboard player / DJ / etc. wants to have a monitor
connected independent of the foldback mix. The ULTRA-DI acts as both a ground isolator and
an unbalanced to balanced converter.

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.

Fig 2.3: Connection to an amplier 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.
