Behringer ULTRA-DI DI100 User manual
Behringer ULTRA-DI DI100 is a versatile and high-quality direct injection box designed to connect unbalanced sources to balanced microphone inputs. It features a wide range of input and output options, including 1/4-inch and XLR connectors, and offers two -20 dB attenuation switches for added flexibility. The DI100 also has a ground lift switch to eliminate hum and noise, and can be powered by either phantom power or a 9V battery.

Welcome to BEHRINGER!
Thank you very much for expressing your confidence in BEHRINGER products by purchasing the ULTRA-DI.
DI stands for Direct Injection. On stage or in the studio there are sources you want to connect to your mixer that arent 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 difficult 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 amplifier, and Inject it Directly into the mixers input without having to use a microphone. But thats 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 amplifier and speakers the impedance to a device determines the performance. With a good power amplifier the load impedance only affects 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) influence 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 consoles 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 specified connected impedances, high in and low out, which means that they only work in a standard application.
Active DI-boxes dont have such restrictions. The signal coming from the input is buffered with an amplifier. The input impedance of the ULTRA-DI is ultra-high so it doesnt affect 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 flat frequency response. Furthermore the BEHRINGER ULTRA-DI can be powered by your consoles phantom power or by battery and switches automatically between these two.
+
You should mute the desk channel before aktivating the DI100.
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.
1. CONTROL ELEMENTS
Fig 1.1: Front & Rear DI100
1 With the ON/OFF switch you can switch the battery power on and off to preserve battery life. Switched off 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/OFF LED will flash once every few seconds, when operating on phantom power the LED will light up continuously.
2 INPUT. Connect the source to this 1/4 jack to receive the signal.
3 To provide maximum flexibility the ULTRA-DI is also fitted 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 amplifier.
+
The 1/4 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. amplifier. Depressing both will give 40 dB attenuation.
+
Only use the -20 dB switches if you are sure the ULTRA-DI is clipping (overloading) and not your mic preamp. 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.
2. DI100 CONFIGURATIONS
The next section will show several different ways the ULTRA-DI can be hooked up.
2.1 Tapping signal from the (Bass)guitar
E
Fig 2.1: Guitar ß DI ß Guitar Amp/Mixer
This figure shows the standard application of any direct injection box. The signal to the amplifier is unaffected, it is just tapped off to be routed to the microphone input of the mixer. Especially bass guitars benefit from this application. It is difficult to find 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 effects devices so that their effect 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.
2.2 Converting the output of a Keyboard / DJ-mixer / Headphone plug
Fig 2.2: DJ-mixer ß 2xDI ß Mixer
This configuration 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 amplifier, 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 thats 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 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.

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.
