ULTRA-DI PRO DI800 User Manual
1. Introduction
Be it on-stage or in the studio, musicians often look for ways to connect certain
signal sources directly to the mixing console. Even though this approach has
obvious advantages, there are still some technical hurdles obstructing its
implementation. For example, keyboards seldom feature balanced outputs,
and guitars can not be directly connected to mixing consoles because of the high
impedance of guitar signals.
A DI-box lets you directly tap into a high-impedance, unbalanced signal—
for example, the signal between a guitar and a guitar amp. From there on,
you can feed the signal directly to a mixing console.
There are active and passive DI-boxes. A passive DI-box is more affordable, but its
performance is highly dependent on the impedance of the equipment to which it
is connected. When the impedance on the mixing console’s end changes, so does
the impedance at the DI-box’s input. A passive DI-box only functions correctly
when the impedance of the connected equipment is exactly specified (high at the
input, low at the output).
On the other hand, active DI-boxes, such as the DI800, are not bound by these
limitations, since the signal located at the input is “buffered” by an amplifier.
The input impedance of the DI800 is extremely high. It does not influence the
sound source and has absolutely no effect on the signal flow though the DI-box.
The output impedance is balanced and is very low, and the signal is far less
susceptible to picking up noise. The ULTRA-DI PRO always transmits signals
optimally, independent of the impedance of the connected equipment.
In addition to being powered by a mains connection, the ULTRA-DI PRO DI800 can
also run on phantom power provided by your mixing console.
◊ To avoid damaging your loudspeakers, always first connect the DI-box
and only then open up the respective channel strip.
1.1 Before you get started
1.1.1 Shipment
Your ULTRA-DI PRO was carefully packed at the assembly plant to assure secure
transport. Should the condition of the cardboard box suggest that damage may
have taken place, please inspect the unit immediately and look for physical
indications of damage.
◊ Damaged units should NEVER be sent directly to us. Please inform the
dealer from whom you acquired the unit immediately as well as the
transportation company from which you took delivery of the unit.

1.1.2 Initial operation
Please make sure the unit is provided with sufficient ventilation, and never place
the ULTRA-DI PRO on top of an amplifier or in the vicinity of a heater to avoid the
risk of overheating.
◊ Before plugging the unit into a power socket, please make sure you
have selected the correct voltage:
The fuse compartment near the power plug socket contains three triangular
markings. Two of these triangles are opposite one another. The voltage indicated
adjacent to these markings is the voltage to which your unit has been set up,
and can be altered by rotating the fuse compartment by 180°. ATTENTION: This
does not apply to export models that were for example manufactured
only for use with 120 V!
◊ If you alter the unit’s voltage, you must change the fuse accordingly.
The correct value of the fuse needed can be found in the
chapter “Specifications”.
◊ Faulty fuses must be replaced with fuses of appropriate rating without
exception! The correct value of the fuses needed can be found in the
chapter “Specifications”.
Power is delivered via the cable enclosed with the unit. All required safety
precautions have been adhered to.
◊ Please make sure that the unit is grounded at all times. For your own
protection, you should never tamper with the grounding of the cable
or the unit itself. The unit shall always be connected to a mains socket
outlet with a protective earthing connection.
1.1.3 Warranty

2. Control Elements
The BEHRINGER ULTRA-DI PRO features eight identically built channels.
The control elements described here refer therefore to all channels.
(1) The INPUT connector is used for connecting unbalanced as well as balanced
signal sources.
(2) Because both INPUT and LINK connectors are wired in parallel, the LINK TRS
connector can be used both as an input and as a direct unbalanced output of
the INPUT signal. For the latter, you can for example connect LINK with the
input of a monitor amplifier.
(3) The unbalanced input signal can be tapped into at the UNBAL OUT TRS
connector – after passing through the amplification circuitry (see (4) and (6)
). Essentially, the signal is identical to the signal located at the XLR output
in the back; the only difference is that it is unbalanced and has therefore no
Ground Lift functionality (see (5) ).
(2)
(4)
(6)
(7) Use the POWER switch to power up your DI800. The POWER switch should
always be in the “Off” position when you are about to connect your unit to
the mains.
◊ To disconnect the unit from the mains, pull out the mains cord plug.
When installing the product, ensure that the plug is easily accessible.
If mounting in a rack, ensure that the mains can be easily disconnected
by a plug or by an all-pole disconnect switch on or near the rack.

the channels 1 to 8. Use a high-quality balanced microphone cable to
establish connection.

(4) The -30 dB attenuation switch increases the operating range of the DI800
considerably, from low signal levels of a high-impedance mic or a guitar,
all the way to speaker connectors of a guitar amplifier.
◊ Use the -30 dB switch only when the DI800 starts distorting (and not
the mic preamp). When this is not the case, avoid using this function,
since the lowest amount of attenuation is desirable in order to obtain
the lowest signal-to-noise ratio possible.
(5) Using the GND LIFT switch, you can fully separate input and output
grounding. Depending on how the equipment to which your DI800 is
connected is grounded, using the GND LIFT switch lets you lower hum
noise or ground loops. When the GND LIFT switch is depressed, the ground
connection is interrupted (the LED is lit red). When the switch is in the
PHANTOM OR MAINS POWER ON setting, the LED is lit green (when the
GND LIFT switch is not pressed).
(6) The +20 dB switch increases the input signal level by 20 dB.
(9) The mains connection is achieved via the standard IEC connector. A matching
power cord is included.
(10) Serial NUMBER. The serial number is located on the top of the unit.
Please take a few minutes and send to us a completely filled out
warranty card within 14 days of the original date of purchase. Otherwise,
warranty claims may be rendered invalid. Or fill out the warranty
information online at behringer.com.
(11) 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 use a fuse with a higher rating (see chapter 5 “Specifications”).

3. Applications
3.3 Converting a microphone signal
3.1 Connecting a guitar/bass 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.

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 lowimpedance 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.

3.4 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.

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.).
Fig. 3.4: Connection to a power amp 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.

4. Audio Connections
◊ Please make sure that your DI800 is installed and handled only by
people with enough technical expertise. Assure that those operating
the unit during and after the installation are sufficiently grounded.
Otherwise, electrostatic charge may alter the performance of your
equipment or damage it permanently.
