1. Introduction

Be it on-s tage or in the stud io, musicians ofte n look for ways to
connec t certain signal s ources direct ly to the mixing cons ole.
Even thoug h this approach has o bvious advantag es, there are still
some technical hurdles obstructing its implementation. For example,
keyboard s seldom feature b alanced output s, and guitars can n ot be
direc tly connected to m ixing consoles b ecause of the high i mpedance
of guitar signals.

A DI-box le ts you directl y tap into a high-imp edance, unbalanced
signal—f or example, the sign al between a guit ar and a guitar amp.
From there o n, you can feed the sig nal directly to a mi xing console.

There are ac tive and passive D I-boxes. A passive D I-box is more
aordab le, but its perf ormance is highly de pendent on the
impedanc e of the equipment to w hich it is connec ted. When the
impedanc e on the mixing conso le’s end changes, so doe s the
impedanc e at the DI-box’s input . A passive DI-box on ly functions
correctly when the impedance of the connected equipment is exactly
speci ed (high at the input, l ow at the output).

On the othe r hand, active DI- boxes, such as the DI80 0, are not bound
by these lim itations, since th e signal located at t he input is “buere d”
by an ampli er. Th e input impedance o f the DI800 is ext remely high.
It does not i nuence the sound s ource and has absolu tely no eect on
the signal  ow though the DI-bo x. The output impe dance is balanced
and is very l ow, and the signal is far les s susceptible to pic king
up noise. The U LTR A-DI PRO always tran smits signals opti mally,
independent of the impedance of the connected equipment.

In additio n to being powered by a ma ins connection, t he ULTRA-DI
PRO DI800 c an also run on phantom p ower provided by your
mixing console.

◊ To avoid damaging your loudspeakers, always first

connec t the DI-box and on ly then open up the r espective
channel strip.

1.1 Before you get started

1.1.1 Shipment

Your ULTRA-DI PRO wa s carefully pac ked at the assembly pl ant to
assure se cure transpor t. Should the condi tion of the cardb oard box
sugges t that damage may have taken p lace, please inspec t the unit
immediat ely and look for physi cal indication s 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 t ook delivery o f the unit. Other wise, all claim s for
replacement/repair may be rendered invalid.

◊ To assure optimal protection of your ULTRA-DI PRO during

1.1.2 Initial operation

Please make su re the unit is provid ed with sucient v entilation,
and never pla ce the ULTRA-DI PRO on top of an a mplier or in the
vicinity of a heater to avoid the risk of overheating.

◊ Before p lugging the uni t into a power socket , please make

sure you have selected the correct voltage:

The fuse c ompartment nea r the power plug socke t 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 u nit has been set up, an d can be altered by rot ating the
fuse comp artment by 180°. ATTENTION: Th is does not appl y to

export models that were for example manufactured only for
use with 120 V!

◊ If you alter t he unit’s voltage, yo u must change th e fuse

accordi ngly. The correc t value of the fus e 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 c an be found in the c hapter “Speci fications ”.

Power is deliv ered via the cable en closed with the u nit. All required
safet y precautions h ave been adhered to.

◊ Please ma ke sure that the unit i s grounded at all t imes.

For your own protection, you should never tamper with
the grou nding of the cab le or the unit itse lf. The unit
shall alw ays be connecte d to a mains socket ou tlet with a
protective earthing connection.

1.1.3 Warranty

2. Control Elements

The BEHRINGE RULTR A-DI PRO features e ight identically b uilt
channels. The control elements described here refer therefore to
all channels.

(1) The INPUT conne ctor is used for co nnecting unba lanced as well

as balanced signal sources.

(2) Becaus e both INPUT and LINK connec tors are wired in p arallel,

the LINK TRS c onnector can b e used both as an input a nd
as a direc t unbalanced outp ut of the INPUT signal. F or the
latter, you ca n for example conne ct LINK with the in put of a
monitor amplier.

(3) The unbala nced input signal c an be tapped into at th e UNBAL

OUT TRS connector – after passing through the amplication

circuitry (see
to the signal l ocated at the XLR ou tput in the back; t he only
dieren ce is that it is unbalanc ed and has therefor e no Ground
Lift f unctionalit y (see

(4) and (6) ). Essentially, the signal is identical

(5) ).

(2) (4) (6)

(5) Using the GND LIFT switch, y ou can fully separ ate input and

output grounding. Depending on how the equipment to which
your DI80 0 is connected is gr ounded, using the GN D LIFT switch
lets you lo wer hum noise or groun d loops. When the GND LI FT
switch is d epressed, the gr ound connecti on is interrupted
(the LED is lit re d). When the switch is in t he PHANTOM OR
MAINS POWER ON s etting, the LED is li t green (when the
GND LIFT sw itch is not presse d).

(6) The +20 dB switch in creases the inpu t signal level by 20 dB.

(7) Use the POWER s witch to power up your DI8 00. The POWER

switch sh ould always be in the “O ” position wh en you are
about to con nect your unit to t he mains.

◊ To disconne ct the unit fro m the mains, pull ou t the mains

cord plu g. When installi ng the produc t, ensure that the p lug
is easily a ccessible. If mo unting in a rack, e nsure that the
mains ca n be easily disco nnected by a plu g or by an all-pole
discon nect switch o n or near the rack.

(11) (10)

(9) (8)

Fig. 2.2: Rear panel connectors

(7)(5)(3)(1)

Fig. 2.1: Front pan el control e lements

(4) The -30 dB atten uation switch inc reases the oper ating range

of the DI80 0 considerably, fro m low signal levels of a hig h­impedanc e mic or a guitar, all the way to sp eaker connector s of
a guitar amplier.

◊ Use the -30 dB swi tch only when the DI 800 starts d istorting

(and not the mi c preamp). When this is n ot the case,
avoid usin g this functi on, since the lowes t amount of
attenu ation is desirab le in order to obt ain the lowest
signal-to-noise ratio possible.

(8) The BAL OUT conn ectors (1 - 8) are the bala nced mic-level

output s of the channels 1 to 8. Us e a high-qualit y balanced
microphone cable to establish connection.

(9) The mains co nnection is achi eved via the stand ard IEC

connec tor. A matching power cord i s included.

(10) Seria l NUMBER. The serial number i s located on the top of t he

unit. Plea se take a few minutes an d send to us a completel y
lled out wa rranty card w ithin 14 days of the origi nal date of
purchas e. Otherwise, wa rranty claims may b e rendered invalid .
Or ll out th e warranty info rmation online at b ehringer.com.

(11) FUSE COMPARTMENT/VOLTAGE SELEC TION: Before pluggin g

the unit int o a power socket, plea se make sure you have sele cted
the corre ct voltage. Fault y fuses must be re placed with fuse s of
appropr iate rating witho ut exception. Som e units feature a f use
compar tment that can be op erated in two di erent positions,
allowing alternating between 230 V and 120 V. Attention: when
using the un it outside of Euro pe (running on 120 V), you have to
use a fuse w ith a higher rating (s ee chapter 5 “Spec ications”).

3. Applications

3.1 Connecting a guitar/bass signal

DI600

Fig. 3.1: Guitar DI-box guitar amp/mixer

This illus tration shows th e standard appli cation of a DI-bo x. The signal
feeding the amplier remains unchanged; it is simply taken and routed
into the amp. T he low-impedance b alanced signal is fo rwarded to the
mic input of the mixing console. This application has its advantages
parti cularly with bas s guitars, bec ause very few mi crophones can
linearly transmit bass frequencies with high signal levels. If you are
using ee cts, inser t the DI800 af ter the eect s device, so that you c an
monitor th e eects via t he PA system or the rec ording as well.

3.3 Converting a microphone signal

Average-quality microphones of ten feature unbalanced,
high-im pedance output s. The DI800 lets y ou wire such mics to t he
mixing console using long cables without running the danger of
inducing hum or interference noise. To this end, the microphone has
to be connec ted to the input of t he DI-box, and the DI -box’s output
needs to be c onnected to the mi c input on the mixin g console.

Fig. 3.3: Microphone connection

3.4 Taking a signal from a speaker output

Sometim es, you want to take a sign al directly fr om a speaker output,
even thoug h just one speaker out put is available. By usi ng the -30 dB
switch on t he DI800, you can conn ect your mixing c onsole to an
amp outpu t (up t o 3,000 Watts into 4 Oh ms), wi thout worryi ng that
the DI800 w ill be damaged due to ove rload! If you are usin g a tube
amp, you shoul d connect a speaker o r a similar load resis tance to the
LINK output.

using long c ables (e.g. connecti ng to a FOH mixer). The signal c an be
looped t hrough to another amp lier via the link ou tput. Thus, you get
