CAUTION!
Possible hearing damage
Making music for a prolonged period and at high volume can cause
hearing damage.
Avoid playing the unit at full volume, especially when using head‐
phones.
NOTICE!
Risk of breakage, possible deformation
When placing the instrument with the fretboard down, there is a risk of
damaging the ngerboard and the tailpiece.
Avoid any compressive load on the rear of the instrument, if it is placed
for the assembly or for service work with the fretboard down on a solid
surface.
Before connecting ampliers or headphones, the volume controls of the
violin and the equipment to be connected must be set to "minimum". This
avoids loud crack noises when switching on.

6 Maintenance
6.1 Changing strings
Maintenance
Strings are subject to a natural aging process, which is also aected by the frequency
of use of the instrument. Changing the strings is recommended if the sound quality
of the instrument decreases audibly. Always replace the complete set of strings
(strings of 4/4 length) and always go string by string. In this way you avoid a strong
temporary bending of the neck due to reduced string tension. The bridge also
remains in the correct position and does not have to be readjusted.
Proceed as follows to change the
strings:
6.2 Battery change
1.For example, loosen the run-down E string from the capstan of the machine
head and from the tailpiece.
2.Thread the new E string into the tailpiece, pull it over the bridge into the cap‐
stan bore of the machine head.
3.Hook the string end to the capstan and tighten the string tension slowly. At the
rst windings, pay particular attention that the string is taut to the mechanics.
4.Make sure that the string is running correctly through the grooves of bridge
and nut at the upper end of the neck.
5.Slowly increase the string tension until the correct pitch is reached. Use a tuner
or a pitch pipe for reference.
6.Proceed in the same way with the A, D and G strings and then tune all strings
again successively to the correct pitch. Note that the string tension will drop a
little and the instrument needs to be retuned several times until the strings
stay in tune.
Replace the inserted batteries if necessary (weak output signal) or at regular intervals.
Open the battery compartment cover on the back of the instrument.
Insert the battery into the battery compartment and close the battery compartment
cover.
NOTICE!
Risk of re due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries.
Ensure that proper polarity is observed when inserting batteries.

Introduction
Balanced and unbalanced transmis‐
sion
Three-pole 1/8" mini phone jack
(stereo, unbalanced)
This chapter will help you select the right cables and plugs to connect your valuable
equipment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is indicated:
Even if a plug ts into the socket, an incorrect connection may result in a destroyed
power amp, a short circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hi
use. Instrument cables with two conductors (one core plus shielding) are typical rep‐
resentatives of the unbalanced transmission. One conductor is ground and shielding
while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at
low levels, such as microphone signals and when using long cables.
In a professional environment, therefore, the balanced transmission is preferred,
because this enables an undisturbed transmission of signals over long distances. In
addition to the conductors ‘Ground’ and ‘Signal’, in a balanced transmission a second
core is added. This also transfers the signal, but phase-shifted by 180°.
Since the interference aects both cores equally, by subtracting the phase-shifted
signals, the interfering signal is completely neutralized. The result is a pure signal
without any noise interference.

9 Cleaning
Clean the instrument and especially the strings after playing with a dry, soft, lint-free
cloth. Stubborn dirt can be removed with a slightly dampened cloth.
Never use cleaners containing alcohol or thinner.
