• For safety reasons, any unauthorised conversion and/or modiﬁ cation to the product is not

permitted.

• Keep electrical devices out of the reach of children. For this reason, be particularly careful

when using the device in the presence of children. They may try to stick objects into the

device through openings in the housing.

• Do not expose the device to high temperatures, dripping or spraying water, strong vibrations

or heavy mechanical stress.

• Do not use the device in a tropical climate.

• Never place vessels or containers containing liquids, such as buckets, vases or plants, on

top of the product or in its vicinity. Liquids could enter the inside of the housing. If this should

happen, the product must not be operated any longer. Take it to a specialist workshop.

• Do not place open sources of ﬁ re such as burning candles on the appliance.

• Do not leave packaging material lying around carelessly. It may become a dangerous play-

thing for children.

• If you have doubts about how the equipment should be operated or how to connect it safely,

consult a trained technician.

specialist.

Features

• Active 2-channel DI box

• High-quality electronics with wide and linear frequency response

• Converts high-ohm, balanced and unbalanced device outputs to balanced, low-ohm outputs

for connecting e.g. devices directly to a mixer input

• Due to low-ohm output impedance and balanced design, lower susceptibility of the audio

transmission to interference and the option of transporting the audio signal without inter-

ference and loss over long distances

• Ground-lift switch with complete ground breaker between audio input and audio output to

prevent ground loops

• Input sensitivity selectable

• Power supply via battery or phantom power

• Solid and stable metal housing

Connection and Control Elements

This DI box has 2 independent channels. Therefore, the connections and controls are dupli-

cated and each of them act on the associated channel (channel 1 and channel 2).

This manual does not describe every channel separately because the functions of both

channels are the same.

(1) GND switch (5) Battery compartment

(2) ATTENUATOR switch (6) POWER switch

(3) INPUT socket (7) OUTPUT socket

(4) THRU socket

Inserting/Replacing the Battery

The DI box can be powered by a battery or phantom power.

If an audio device with phantom power supply is connected to one of the two outputs OUTPUT

(7), the device can also be operated without a battery.

Batteries should be kept out of the reach of children.

Keep them out of the reach of children. Do not leave batteries lying around.

There is a risk that the batteries may be swallowed by children or pets. If they

are swallowed, consult a doctor immediately.

Make sure that the polarity is correct when inserting the battery.

Remove the battery when the device will not be used for a while.

Leaking or damaged batteries can cause burns if they come into contact with

the skin. You should therefore wear suitable protective gloves.

The batteries must not be short-circuited or thrown into the ﬁ re. Do not

attempt to recharge the batteries. There is a risk of explosion. Charge

rechargeable batteries intended for that use only. Use an appropriate battery

charger.

In the case of battery operation, turn the device off always after use using the

POWER switch (6) to avoid unnecessary battery discharge.

• Open the battery compartment (5) by opening the the screw joint.

• Plug a 9V block battery to the battery contact. The battery can be plugged in only with the

correct polarity.

• Place the batteries in the battery compartment.

• Close the battery compartment (5) again by replacing the cover and screwing it again.

• If the playback sound is distorted, or the device no longer works, the batteries are ﬂ at and

have to be replaced as described above.

Set-up

Select a level, ﬂ at and stable installation location.

Protect valuable furniture surfaces by using an appropriate underlay; otherwise, it may cause

scratches.

Connection

Always use suitably shielded audio cables to connect inputs and outputs. Use

of other cables may lead to interference.

To avoid distortions or mismatchings that could damage the unit, the inputs

and outputs must only be connected to devices with the suitable TRS or XLR

terminals.

• Connect the output from your audio source (e.g. electric guitar) to the INPUT (3). Here,

balanced or unbalanced signals can be connected with TRS or XLR terminal.

• If you want to connect to the original signal of your audio source to another device, connect

the input of this device to the THRU terminal (4). The THRU terminal (4) is connected in

parallel with the INPUT (3).

• Connect OUTPUT (7) to the input of the subsequent audio device (e.g. mixer).

Item no. 40 88 61

Version 05/13

These operating instructions are a publication by Conrad Electronic SE, Klaus-Conrad-Str. 1,

D-92240 Hirschau (www.conrad.com).

All rights including translation reserved. Reproduction by any method, e.g. photocopy, microﬁ lming,

or the capture in electronic data processing systems require the prior written approval by the editor.

Reprinting, also in part, is prohibited.

These operating instructions represent the technical status at the time of printing. Changes in

technology and equipment reserved.

Operation

• Should the device be operated on phantom power of another device that is connected to one

of the two outputs OUTPUT (7), the POWER (6) switch need not be pressed. Even if a battery

is installed, the power supply is primarily via the phantom power.

• Should the device be operated on battery, press the POWER (6) switch to turn it on.

• The POWER (6) switch is colour-coded and lights up with different brightness, depending on

the type of power supply:

green / red dark > power supply via battery

green / red light > power supply via phantom power on both outputs

green light > power supply via phantom power of OUTPUT 1

red light > power supply via phantom power of OUTPUT 2

• Adjust the input sensitivity of the DI box to the output level of your source device using the

ATTENUATOR (2) switch:

Switch not pressed > 0 dB (no attenuation of the signal)

Button pressed > -30 dB (attenuation of the signal)

• Should faults due to ground loops occur during the audio transmission, press the GND (1)

switch. In the GND position, the signal ground is connected to the ground of the output signal,

whereas in the LIFT position, the signal ground is separated from the ground of the output

signal.

Maintenance and Cleaning

Please use a soft, dry, clean cloth for cleaning.

Do not use any chemical cleaning agents, as they can discolour the surface ﬁ nish of the casing.
