3. Respect the warnings.
4. Follow all these instructions.
5. Do not use near a water source.
6. Clean only with a dry and clean cloth.
7. Don’t place near a heat source, that is near any equipment that produces heat.
8. Don’t use another Power Supply than the one that is provided with the purchase.
9. In case of lost or damage of the Power Supply, contact KLEMENTZ before using a new power supply.
10. Make sure that the Power Supply block is not getting trampled, neither on the transformer part, nor on the
cable or connector part.
11. Unplug this equipment during a thunderstorm or as soon as you have finished using it.
12. Please directly contact KLEMENTZ for any After Sale service. This is mandatory in case the equipment is
damaged : if the cable, the Power Supply or connectors of the equipment are damaged, if liquid has been
knocked over it or if objects have fallen on it, if it has been exposed to rain or humidity, if it does not work
correctly or if it has fallen.
13. Do not let the power supply block plugged in a socket when the equipment is not in use. The power supply
bloc is always powered even if the power switch of the unit is in OFF position. To completely disconnect
the machine, remove the power supply block from the mains plug.
14. In any setup case, leave a sufficient space for the equipment to cool properly. You can arrange other
equipment on the top and/or on the bottom of the unit, but some (like amplifiers) may cause a buzz or
generate too much heat, it may cause damage your equipment or degrade its performances.
15. In order to evaluate any risk of fire or electric chock, keep this equipment away from any source of
humidity and splash of any type. The equipment must also be kept away from any object filled with liquid
(bottled drinks, vase, …)

QUICK START
For a correct use of your NJD BOX, please read the instructions below:
1. This NJD BOX must be plugged into a LINE input of your mixer or preamp. An effect processor
can be plugged between your NJD BOX and the LINE input of your mixer, only if the input of
your effect processor is also a LINE type input. In any case, do not plug your NJD BOX in a
Microphone input or it may damage it. Please see the « Typical wiring » section for a more
detailed description of the possible wirings.
2. In you use the NJD BOX with a DJ mixer, a [MONO JACK 6.35mm] to [2 x RCA (Cinch)] is
necessary.
NOTE
On the cable described above, the 6.35mm JACK must be MONO. If it is STEREO, the sound will be
transmitted only on the left channel of your sound system.
3. Before powering the NJD BOX, ensure that the Volume potentiometer is at the minimum
position. Put your NJD BOX on, activate the trigger and progressively increase the volume until
you have a sound.
4. Only use the provided power supply block.

CONTROLS & USE
FRONT PANEL
The table below explains the features of the controls above.
FUNCTIONS
USAGE
LFO SPEED
4-Positions rotary switch allowing setting the oscillation speed of the LFO.
In position 1 (fully anti-clockwise), the oscillation speed will be lowest
and so the modulation will be slow.
In position 2, the speed will be faster than in position 1.
In position 3, the speed will be faster than in position 2.
In the last position (fully clockwise), said “manual position”, the LFO will
stop oscillating. You can then use the two push buttons labeled
“Modulation” to manually modulate the pitch.
MODES
4-Positions Rotary switch allowing choosing between 4 types of different
sounds.

PITCH
Rotary potentiometer allowing to set the base pitch of the signal :
Set at the minimum position, the base sound pitch will be low.
Set at the maximum (fully clockwise), the base sound pitch will be high.
LFO LED
Light indicating the oscillation speed of the LFO
MODULATION
These push buttons will allow you to manually modulate the sound pitch when
used with the “LFO SPEED” in 4th (“Manual”) position.
SHAPE SW
2-position switch allowing setting the base waveform of the NJD.
TRIGGERS
Push-Button and Switch triggering the output of the sound.

TYPICAL WIRING
DIRECT WIRING
The simplest connection is the « Serial » one, meaning that the output of the NJD BOX is directly
inserted into a LINE input of the mixer or preamplifier.
This configuration is the simplest. To apply an effect on the NJD BOX, your mixer or preamplifier
will need to have the effect send and return functionality.
The diagram of this example is presented below:

THRU FX PROCESSOR
The use of the dub siren (the NJD BOX is one) is often coupled with an effect processor (for
example Echo or Reverb). If your mixer or preamplifier does not have send/return functionality or if you
prefer to keep this effect loop for another use, it is possible to plug the output of your NJD BOX in the
input of an effect processor (DUB DELAY for example). The output of the effect processor will be
plugged into a LINE input of your mixer or preamplifier. The below diagram shows this wiring type:
NOTE
Some effect processors are made to be used with an instrument (a guitar for example) or a
microphone. Before plugging your NJD BOX on your processor, check that the input of your processor
is a LINE type. The output level of your NJD BOX being relatively high, it can damage the input of your
effect processor.
