Introduction
Thank you very much for purchasing the Nowsonic DBox Two. This active 2 channel Direct Injection-Box serves for connecting up to two high impedance signals (such as instrument signals, 50 kOhm) or two line level sources (such as a keyboard, DJ mixer etc.). The signals may then be connected to the microphone inputs of a mixing desk or to external mic preamplifiers via the balanced low impedance outputs (600 ohms) of the DBox Two. Thanks to the rugged metal housing and power supply from an internal battery, the DBox Two is equally suited for use in a recording studio or on stage. Please take your time to read these instructions carefully in order to operate the DBox Two properly. Please check the unit after unpacking for any damages. In case the housing is visibly damaged, please do not operate the unit, but con­tact your local dealer from whom you have purchased it.

Operating instructions
1) This DI box for indoor use was designed for lossless transmission
of audio signals over long distances.
2) Power is supplied via a standard 9V battery (type PP3). Batteries contain hazardous waste substances and therefore must be dispo­sed properly. If you want to dispose the unit itself, please remove the internal battery first.
3) Turn off the DBox Two via its POWER switch if the device is not in use: This will prolong the battery‘s lifetime and avoids frequent replacement of the battery.
4) When inserting a battery, please take care of connecting the battery terminals correctly.
5) Don‘t let any batteries lie around for any reason, since children and/or domestic animals might swallow them. If a battery has been swallowed, immediately call a doctor!
6) Leaking or damaged batteries may cause skin irritations. Always wear protective gloves when changing batteries.
7) Be aware that the battery may not be short-circuited, thrown into a fire or recharged. In this case it may explode!
8) Please make sure that no liquids spill into the housing. Otherwise let the unit be checked by a qualified technician before operating it again. Any damages caused by liquids that have been spilled of the housing are not subject to warranty.
9) Do not heavily shake the unit. Avoid excessive force on the housing while operating the unit.
10) The operating temperature must always be between -5° C and +45° C. Do not operate the unit next to heat sources like radiators and do not expose it to direct sunlight.
11) The relative environmental humidity must not exceed 50% with a temperature of +45° C.
12) The unit must be operated in an altitude between -20 up to +2.000 a.s.l.
13) Please make sure that the unit is only operated by qualified personnel. Damages on the unit are often caused by a faulty operation!
14) Do not use any solvents or aggressive cleaning agents when cleaning the unit! Please use a soft and dry cloth instead.
15) Please use the original packing material for transporting the device.
16) Please note that unauthorized modifications are not allowed due to safety reasons!
17) Please note: If you operate the device in any other way than described in this manual, the device may be damaged. In addition the warranty may be void.

Operation
1) A DI box converts unbalanced sources like the signal of an electric
guitar or a keyboard into a balanced signal for connecting to any microphone input of a mixing console or microphone preamplifier.
2) In addition, the impedance of the Hi-Z signal is adapted to the low-impedance input of a subsequent microphone preamplifier.
3) Due to the design, you can connect either two monophonic sour­ces (such as an electric guitar and a bass guitar) or a stereophonic device (such as a stereo keyboard or a DJ mixer) to the DBox Two.
4) Depending on the configuration, you select the MONO or STEREO mode via the corresponding switch: In STEREO mode, the signal from INPUT 1 is routed to OUTPUT 1 and INPUT 2 is routed to OUT­PUT 2. If MONO mode is active, the signal from INPUT 1 is routed to both outputs: INPUT 2 then is not active.
5) The PHASE switch reverses the polarity of both channels; activate the PHASE switch if you hear any phase cancellation with other signals.
6) The HI CUT switch activates a low pass filter for damping signals above 8 kHz. Activate the HI CUT to eliminate unwanted noise and hiss or to damp the high frequency range (similar as a loudspeaker).
8) In order to obtain the best sound quality, please use only high­quality cables. Please make sure that the cables are properly connected.
9) Connect your audio sources (e.g. electrical guitar, bass, keyboard etc.) to the sockets named INPUT 1 and INPUT 2.

Operation
9) If you want to loop through the input signals to subsequent
guitar amplifiers etc., connect the amplifiers with the unbalanced LINK 1 or LINK 2 jacks using standard monophonic cables.
10) If any noise occurs, please activate the Ground-Lift switch. In addition, you may adapt the input gain as required using the PAD switch (+20dB for low-level line sources, 0dB for electric guitars,
-30dB for power amplifier outputs) if any clipping occurs.
11) Connect the OUTPUT 1 and OUTPUT 2 jacks with two microphone inputs on your mixing desk using balanced XLR cables. Of course you can feed the DBox Two monophonic with only one source. Accordingly you only have to use one output.
Inserting and changing the battery
Please follow all instructions for operating the device.
Open the battery compartment on the side panel next to the INPUT
2 and LINK 2 sockets respectively.
In order to insert the new battery, you must first remove the old
battery from the compartment.
The acid of leaking or damaged batteries may cause heavy skin
irritations. Therefore always wear protective gloves when changing batteries.
Insert the new battery: Please take care of connecting the battery
terminals correctly. Close the battery compartment and lock the cover. Turn off the POWER switch of the DBox Two if the device is not used
for a longer period. In addition you should remove the battery to
avoid battery leaking. For a long operating time please use Alkaline batteries only. Turn off
the DBox Two via its POWER switch if you don‘t use it.

Einleitung
Herzlichen Glückwunsch zum Kauf der Nowsonic DBox Two. Diese zweikanalige aktive Direct-Injection-Box dient zum Anschluss von bis zu zwei hochohmigen Signalquellen (z. B. Instrumentensignale, 50 kOhm) oder zwei Quellen mit Linepegel (z. B. Keyboard, DJ-Mixer o.ä.). Über die niederohmigen symmetrischen Ausgänge (600 Ohm) der DBox Two können Sie die Signale dann direkt mit den Mikrofon­Eingängen eines Mischpults oder externen Mikrofonverstärkern verbinden. Durch das stabile Metallgehäuse und die Stromversorgung über eine interne Batterie eignet sich die DBox Two gleichermaßen für den Betrieb im Studio wie auf der Bühne. Bitte nehmen Sie sich Zeit und lesen Sie diese Bedienungsanleitung sorgfältig durch, damit Sie die DBox Two richtig in Betrieb nehmen können. Bitte überprüfen Sie das Gerät nach dem Auspacken auf etwaige Schäden: Sofern Schäden am Gehäuse sichtbar sind, nehmen Sie das Gerät bitte nicht in Betrieb, sondern wenden sich sofort an Ihren lokalen Händler, bei dem Sie das Gerät gekauft haben.
